15、ptive innovations will emerge into thebusiness model and industrial ecology.1.New Perception-Sensing the Physical World Comprehensivelyand IntelligentlyWith the advancement of internet of things(IoT)technology andapplications,the sensing technology in the future will be developedfromsingle-functiona
16、ndlowintelligencetomultifunction,collaborative,and high intelligence to support emerging application2scenarios such as integrated sensing and communication,andhuman digital twins.1.1 Sensing TechnologyAs a bridge that connects between the physical and the digitalworld,the sensing technology has beco
17、me the cornerstone ofindustrial digitalization,and is increasingly important to thedevelopment of the whole industry.In the future,the developmentof sensors will feature the fusion of various technologies,thesensors will integrate with technologies such as communication,energy harvesting,and heterog
18、eneous integration,thus achievemore accurate,reliable,and powerful sensing capabilities.Integrated sensing and communicationIn the future,the sensing technology will no longer be limited tohardware devices,instead,it can realize environmental perceptionby employing the ubiquitous network signals.Whe
19、n an objectmoving in radio frequency(RF)field,the position,moving speed,moving direction,and attitude of the object can be identified byanalyzing the signal variation of the radio electromagnetic wave,thus a large-scale environment perception can be realized.Theintegrated sensing and communication t
20、echnology is the fusion ofcommunication and radar,and therefore,the base station needs toallocate sensing resources in the time-domain and spatial-domain,and needs to support sensing and data processing functions,3although the current relevant research is still in the early stage.Passive-sensing tec
21、hnologyBy integrating environmental energy harvesting technology withsensors,the sensors can employ vibration,temperature,light,andcommunication signals as energy sources,thus the sensors requireno power supply,and can greatly expand the application scenarios.The key of passive sensing technology is
22、 to improve energyconversion efficiency,which is related to the physics and materialsscience,and it also involves low-voltage energy storage mechanisms,efficient energy management algorithms and software.Therefore,the biggest challenge of passive sensing is to combine basic science,electronic circui
23、t,and software together,and meanwhile achieveoptimal balance among those technologies.Microsystem technologyWith emerging technologies,the performance of integrated circuit(IC)is gradually approaching to the limit of Moores law.Therefore,the industry integrating microelectronics with other disciplin
24、es toproduce a new technology microsystems,thus to achieve Morethan Moore.The microsystem technology is a combination ofmicroelectronics,micro-electro-mechanical system(MEMS)andoptoelectronics,featuring miniaturization and systematization.Microsystems are miniaturized by using advanced integrationsc
25、hemes to produce new functions at the system level,which4greatly increases the function density of systems.The difficulty ofmicrosystems technology is to ensure high integration density whilerealizing coupling andcoalition between different modules,andthe microminiaturization also causes challenges
26、to robustness,reliability,and validation technologies of microsystem technology.Smart sensingThe advancement of IoT,big data and AI technologies facilitates thedigital and intelligent transformation of society,enabling all devicesto be connected and integrated to achieve data-driven andaugmented Int
27、elligence.The future sensing technology will havenew features:first,the intelligence,including strong sensing abilityand advanced understanding ability;second,the autonomy,whenoperating in an unattended environments,the sensors have strongenvironmental adaptability and self-organization ability;Thir
28、d,thecollaboration,devices shall dynamically share resources(data,knowledge,computing,communication and power resources)witheach other,and provide complex services through cooperation.However,to achieve those features,smart sensing needs to focuson the following challenges:First,the intelligence lev
29、el of IoTservices needs to be improved.The system requires the ability tolearn from small sample data,which can be used to build an IoTknowledge graph,realize resource virtualization,collaborativecomputingenvironmentsharing,andthustoachievehighintelligence level.Second,the learning ability of IoT se
30、rvice needs to5be improved.Through the data interaction between wearabledevices,environments,and personnel,the IoT devices shouldrecognize and predict human behavior and emotions,and provideservices on demand to meet individual needs.Third,the contextlinkage ability of IoT service needs to be enhanc
31、ed,for instance,themany-to-many mapping between user demand and data requirescomplex computing,and the behavior of sensors and actuatorsneeds to be designed with corresponding coordination models.1.2 Human Digital TwinDigital twins is one of the typical use cases of the new perception,which is based
32、 on emerging sensing technologies and intelligentperception capabilities,that can perform somatosensory perception,emotional perception,and consciousness perception of the humanbody,and understand the neuroplasticity of the human brain bylearning human somatosensory data and data of the devices ande
33、nvironments used by human beings,so that the human body andthe virtual twin can be mapped to each other.The digital twin alsoinvolves acquisition and transmission technologies in the humandomainsuchasbrain-computerinterfaceandmolecularcommunication,aswellasinformationprocessingsuchascomputation and
34、presentation.The realization of digital twins faces many technical and ethicalchallenges.The first is how to effectively fuse data from differentsources and use AI and other algorithms to achieve accurate6diagnosis and prediction for the somatic twin;the second is how toread and quantify human emoti
35、ons and five sensory sensations forthe empathic twin.In vivo information transfer requires a complexhuman channel environment,and related technologies such asmulti-dimensional heterogeneous transmission system based onmolecularcommunicationstillneedtobeimprovedandsystematically validated.Third,brain
36、 science is still in its infancy,andthere is need for breakthroughs in brain-computer interfacetechnologies for consciousness perception.Fourth,many newethical and privacy security risks willemerge,and correspondingpolicies and regulations need to be formulated.2.New Terminal-A New Form of Human-com
37、puter InteractionThe new human-computer interaction will shorten the distancebetween man and machine.In the future,new terminals should becomfortable,convenient,bio friendly,low power consuming andubiquitous.Flexible electronic devices will be closer to the humanbody and even integrated into the bod
38、y;holographic display cangenerate more immersive and interactive imaging effects,and bringricher sensory experience to users.The new terminal may beinvisible,enabling users to obtain a richer and non-perceptualexperience,by ubiquitous sensing equipment,cloud computingpower,friendlyhuman-computerinte
39、ractiontechnologyandubiquitous communication ability.72.1Flexible ElectronicsFlexible electronics can be summarized as an emerging electronictechnology that makes organic/inorganic electronic devices onflexible plastic and thin metal substrates.It can be used for flexibleelectronic display,organic l
40、ight emitting diodeorganic light-emitting diode(OLED),printing radio frequency identification(RFID),thin film solarpanel,with unique flexibility and ductility,as well as efficient andlow-cost manufacturing process.Like traditional IC technology,manufacturing technology andequipment are the main driv
41、ing force for the development offlexibleelectronictechnology.Flexiblethinfilmtransistortechnology is one of the important technologies.Compared withrigid silicon-based ICs,flexible non silicon-based chips are realizedby making thin-film transistors on plastic or metal foil substrates.Itis not only c
42、heaper to manufacture,but also thinner and moreflexible.The key of flexible electronic manufacturing is how tomanufacture smaller flexible electronic devices on a larger substrateat a lower cost.Its technical level can be measured by thecharacteristic size of the chip and the area of the substrate.O
43、nlywhen the transistor contained in the chip reaches a certain density,the performance of flexible chip can be compared with that oftraditional silicon-based chip.8Flexible electronic technology will break through the intrinsiclimitationsofclassicalsilicon-basedelectronicsandprovideimportant opportu
44、nities for future industrial development such asdevicedesignintegration,energyrevolutionandmedicaltechnology reform in the post molar era.Currently,there are twomainchallenges.Thefirstismechanicalproblems.Flexibleelectronic components will continue to bear alternating stress whenthey are folded and
45、bent repeatedly,which is easy to crack after along time.It is mainly overcome by structural design.The secondchallenge is the problem of electronic packaging,that is,how topackage the components integrated on the flexible substrate tightlyand achieve the expected function.2.2Holographic DisplayHolog
46、raphic communication will combine AI,big data and othertechnologies to build a multi-agent,realize the integration andinteraction between the physical world and the digital world,andprovide a new life experience of blending virtual and real.Holographic communication will integrate AI and a variety o
47、finteraction modes,and use new holographic display terminals andequipment to provide users with a two-way circular couplingexperience from multiple dimensions such as vision,hearing andtouch.The key technologies of holographic communication includeholographic display,sensing interaction and data com
48、munication.9Holographic display may carry a variety of new intelligent terminals,involving dynamic computing,three-dimensional display,opticalencryption and compression coding and other technologies;Sensinginteraction needs to support multi-channel virtual reality fusioninteraction ability(such as g
49、esture,posture,eye movement,voice,smell and touch).The multi-dimensional information is very easy tobe distorted by noise,jitter,packet loss and other factors,which is agreat challenge to maintain the naturalness,realism,immersion andsynchronization of interaction.A large number of complex datagener
50、ated by the interaction between holographic display andsensing have high requirements for communication.These data maycome from video,audio,touch,or people,physical objects andbackground environment.The required network transmissionbandwidth is very large.Efficient encoding/decoding technologymust b
51、e used for compression processing.At the same time,itneeds technical support such as ultra-large bandwidth,ultra-lowdelay,cloudedgeintegrationcomputingpower,highsynchronization and strong security.3.New Computing Power-Enabling High-Efficient and MassiveSecure Data ProcessingAs ICT pushes the world
52、into the digital economy society,themassive data has become as an increasing important factor ofproduction.As a new production tool,computing has penetrated10into many aspects of economy and society.In other words,computing power is productivity.The demand for computing poweris growing rapidly,leadi
53、ng to a big change in global computingtechnology and industries.And its system presents a trend ofdiversificationandcoexistenceofmultipleevolutions.Thenon-classical computing,such as quantum computing,opticalcomputing,lightweight computing,and privacy computing,isgradually moving from theory to prac
54、tice.3.1 Quantum ComputingQuantum computing is a new computing mode that followsquantum mechanics to control quantum information units forcomputation.It uses quantum bits as the basic unit,and realizesdata storage and calculation through the controllable evolution ofquantum states.It has the advanta
55、ge of strong parallel computingcapability and can provide exponential speedup on some specificproblems.Quantum computing can be used for quantum simulations,quantum optimization algorithms,quantum cloud computing,andquantum-enhanced AI,where the quantum optimization is aneffective approach to solve
56、many optimization problems includingthe direction of information processing.The high computing powerand high parallel computing requirements of AI make it possible tocombine quantum computing with AI.The model of quantumcomputing+AI has been used in data clustering and other fields.11However,the app
57、lication of quantum computing in informationcommunication still faces some great challenges.First of all,thecombination of AI and quantum computing is still in the stage oftheoretical exploration,which is far from practical application,andthe improvement of quantum computing on machine learning is n
58、otclear.Secondly,since quantum computing can only solve specificoptimization problems,it is necessary to explore the feasibility ofquantum computing on general optimization problems.Thirdly,there are some bottlenecks in the miniaturization and stability ofquantum computer.No matter what type of quan
59、tum computer is(superconductivity-based,optical-based,ion trap-based or nuclearmagnetic resonance-based),there are limitations in maintainingquantum coherence time and in producing coherent quantum,bothof which require extremely high material technology.3.2 Optical ComputingDue to the resistance,cap
60、acitance and induction,significantamount of heat would be generated when electric charges movefrequently inside the devices.As the circuit integration level keepsgrowing for communications and computing devices,the energyconsumption associated with the moving of charges increaseexplosively and becom
61、es unsustainable.Hence,it is quite necessaryto explore a computing system that is more energy efficient.Optical computer is a potential candidate with the aim to achievefull-opticalcomputingwhichincludes:opticalprocessors,12transmitter/receiver of optical data,optical memory,etc.Amongthem,optical pr
62、ocessors are able to fulfill the functions such ascontrolled amplification and optical logic-gates,based on thenonlinear diffractions of optical material/devices.Optical datatransmissioncanbethroughopticalfibersorspatiallightmodulators(similar to optical lenses).Optical memory can be madeof phase-ch
63、ange or thermal-change based optical disks.The biggestadvantage of optical computing is the low energy consumption.Apart from the optical-to-electro and electro-to-optical conversionsat the input and output ports,there is no electric charges movinginside the devices.Another big advantage of optical
64、computing isthat it can achieve massive inter-connection very efficiently,forinstance,a spatial light modulator is essentially an analog antennawith very large aperture which can distribute optical signals frommultiple branches to different receivers.Currently,the main challenge of optical computing
65、 is the maturityof optical devices which involves optical processing,optical datatransmission and optical memory.Significant breakthrough isneeded in the field of optics and material science.3.3 Lightweight ComputingIt has been envisioned that there will be trillions of AI-enabled IoTdevices globall
66、y.Computing on resource-constrained IoT devicesmust be energy-efficient to minimize the energy needs.Differentapproaches are needed given the diversity of IoT applications.13Using energy harvesting with low power chips in the IoT devices issuch an approach.For example,low-power microcontrollers(MCUs
67、)may consume only a few milliwatts to microwatts.Energy may beharvested from many sources,e.g.,radio waves,temperatures,vibrations,or sunlight.Thus,the research on technologies of energyharvesting is required.While the IoT devices may harvest energy,the energy-gain functionmay be challenged to keep
68、up with the computing applications.Thisis especially hard for sophisticated applications that need muchenergy.It may result in software problems if the device energy runsout during the application processes.In order to maintaincomputing correctness on such devices,additional measures areneeded to de
69、al with the outages and more researches on efficientcomputing in IoT devices are needed.Further,IoT devices are usually subject to resource constraints,e.g.,data,knowledge,energy,computing and communication resources.This requires IoT systems to be resource-aware,which cansimultaneously take into ac
70、count of status of sensor battery,thestatusofactuatorpowersource,andthe possibleenergyrequirement of the applications.Researches on resource-aware,energy-efficient computing technologies are requiredto realizelow-cost,small and efficient future IoT systems.143.4 Privacy ComputingAs the realization o
71、f cross-domain data fusion and data valuemining in a secure and compliant manner has become an urgentdemand in the era of big data,privacy computing technologiesaround multi-party secure computing and federated learning areattractingwidespreadattention.Privacycomputingutilizescutting-edge cryptograp
72、hy technologies such as secret sharing,oblivioustransfer,garbledcircuit,homomorphicencryptioncomputing,and zero-knowledge proof to make data available andinvisible.However,privacy computing needs further research andbreakthroughs in distributed computing systems,the improvementof trusted and secure
73、computing efficiency,the guarantee of modelaccuracy,the standardization of data elements,and the complianceof business development.4.New Security-A Built-in Security System for the FutureNetworkWith the openness of the network and the emerging of newtechnologies,the traditional security system based
74、 on patching andplug-in ideologies can no longer meet the needs of the increasinglycomplex network environment,which demands built-in securitycapabilities with network trust,secure data sharing and proactiveimmunity support,and ultimately realizes the transformation from15network security to secured
75、 network.4.1 Secure Quantum CommunicationThe development of quantum computers has been accelerating andtech giants including Google,IBM,Microsoft,and Intel haveinvested heavily into the research and development(R&D)ofquantum computing,which can solve mathematical problemsfundamentally challenging fo
76、r current computers,for example,Quantum computing may greatly reduce the time of crackingcommonly used asymmetric encryption algorithms such as the RSAalgorithm.Asymmetric encryption relies on the difficulty offactoring large numbers into primes,but the prime factorizationalgorithm based on quantum
77、computing(e.g,Shor)can find primefactors of large numbers in a much shorter period of time,whichshakes the foundation of asymmetric cryptography systems basedon the complex mathematical problems.Moreover,quantum entanglement is crucial for long-distancequantum communication and scalable quantum comp
78、uting,but thestorage of quantum entanglement,especially high-dimensionalquantum entanglement is currently a challenge and must be solvedin order to build a quantum communication network capable ofhigh volume and long-distance transmission.As a result,it is needed to carry out researches on quantum-b
79、asedsecurity technologies in the context of mobile communication,16including:Quantum attack resistant cryptographic algorithms;Thelastone-kilometertransmissionproblemofquantum crypto key;Mathematically proven secure crypto key by using thetime-varying,reciprocal and spatially irrelevant properties o
80、fwireless channels;The storage of quantum for long-distance and securequantum communication etc.4.2 Dynamic Data Coloring TechnologyAs data gradually become critical assets in business operations andcarry great values,the risks of unauthorized data access willincreaseexponentiallywhendataflowwithino
81、routsideorganizations.Traditional data security technologies are insufficientin solving data pollution,data privacy violation,and data leakageintractability problems exacerbated by increasing data fluidity.Inthe future,data security capabilities need to adapt to the datafluidity to ensure dynamic se
82、curity protection for flowing data.Therefore,it is necessary to study the data security technologieswith data fluidity awareness,built-in support of data asset labeling,data flow path management and risk detection,which will provide17the capabilities of data pollution control,data value assessment,a
83、nd data tracing required for data protection in future dynamicnetwork environment.4.3.Trusted Built-in Security SystemThe traditional security systems are no longer able to effectivelydefend against security risk uncertainty and potential attacksbecause of their plug-in and patching based mechanisms
84、.There aretwo fundamental challenges:Transform network from risk uncertainty to certainty ofsecurity trust with the support of trust relationship establishment,transmission and evaluation;Evolve from passive protection of network to activeself-immunity security to meet the requirements of predictabl
85、enetwork behavior,strict management,and extreme end-to-enddifferentiation for different services.Zero trust is a security concept based on continuous verification,never trust,which will play an important role in the future mobilenetworks and break the traditional practice of providing securitymostly
86、 at the network border.Facing the future open networkenvironment,its of great importance to study the securityarchitecture with deep integration of zero trust and communicationnetworks,to build a trusted endogenous security system,and to18plant security into the networks genes to provide ultimate se
87、curityfeatures such as self-immunity and self-evolution.4.4 Unified Identity Authentication based on Biometric and DeviceCharacteristicsThedevelopmentofthedigitaleconomyandmobilecommunications has brought a growing number of economicactivities with high security requirements on mobile networks,sucha
88、s comprehensive government administration,financial payment,medical care,etc.In these scenarios there are demandingrequirements for users identity authentication;however,currentlymobile phone numbers are the single commonly used real nameidentifiers for users,which cant meet the needs of consistency
89、 ofauthentication between business users and mobile device owners.In recent years various biometric authentication technologies haveemerged followingthe development of sensorand featurerecognition technologies,such as fingerprints,palm prints,face,iris,voiceprint,etc.The biometric based authenticati
90、on has theadvantageofconveniencewithoutsettingandmemorizingpasswords,and is rapidly being used in various applications.On theother hand,the device authentication based on RF fingerprints canperform individual identification of wireless devices at the physicallayer,which has also become a future rese
91、arch direction.A trusted digital identity authentication system should be built for19mobile networks with unified identity authentication which shouldcombinebiometrics,devicefingerprintandtraditionalauthenticationtechniques.Forthisgoalmoreresearchoncutting-edge intelligent authentication mechanisms
92、incorporatingmultiplebiometricfeatures,multipleauthenticationfactors,continuous assessment and verification are needed.5.Low-Carbon Innovation-Help to Accomplish Carbon Peakingand Carbon Neutrality GoalsIn September 2020,China announced at United Nations GeneralAssembly(UNGA)that it will strive to p
93、eak carbon dioxide emissionsby 2030 and achieve carbon neutrality by 2060,which is an arduoustask.Complex and large scale communication systems are seen ashigh energy consumption(EC)infrastructures,therefore need todecrease carbon emissions by focusing on two possible solutions:reducing expenditure
94、and broadening sources of income,i.e.tocurb energy consumption and switch to green energy.In terms of reducing expenditure,due to the huge cost pressure onnetwork operators given by the high EC of network devices,ZeroWattsZero Bits is necessary to be realized both in EC andcommunicationvolumessimult
95、aneouslyforfuturenetworks.Omni-directionalimprovementofenergyefficiencyandECreduction relies on the following technologies of high efficiency20radiosignalingtransmission,highefficiencyhardwareimplementation,deepsleeptechnology,integrationofcommunication technology and other applications,etc.5.1 High
96、 Efficiency Radio Signaling TransmissionFuture network will adopt minimal signaling structure,reducingenergy radiation from multi-dimension including source domain,time domain,frequency domain and spatial domain.For example,new encoding method can be used in source domain to transmitmore information
97、 with fewer bits;innovation waveform is beingdeveloped in time domain to increase sleep time duration ofdevices;more technologies in spatial domain such as very largescaleactivemeta-materialphasedantennaandlasercommunication can help to form more precisely directed beams,and lower energy waste of ra
98、dio radiation.5.2 High Efficiency Hardware ImplementationFirst,we must improve the efficiency of RF devices.RF devices arethe main EC components of traditional base station system,amongwhich RF power amplifier(PA)has the highest proportion of powerconsumption.In terms of material and process,the fou
99、rthgeneration semiconductor will be applied in PA;and new circuit andalgorithm design can be used to further simplify the architecture,for instance,direct RF sampling technology and fewer interfacesbetween modules will increase RF efficiency to 80%,90%or even21100%.Second,we must reduce digital proc
100、essing EC.Future network willuse passive optical devices instead of active chip.Thanks torefraction,scattering and other optical properties,series of complexlogical operations in digital computing can be completed withalmost zero EC.Furthermore,improving chip process will be ofbenefit to gradually a
101、pproach the power density limit,andtechnologies like chiplet encapsulation are also expected to breakMoores Law to further lower the EC of digital signal processing.Third,we must promote heat dissipation.Let the heat out of therunning system through liquid cooling at the plate levelandmaterial of fa
102、st thermal conductivity,to increase the power densitylimit of the chip.The main challenges here are high price of newmaterials,increase of deployment and maintenance cost,difficultyof production process,and low degree of supply chain autonomy,etc.5.3 Deep Sleep TechnologyTraffic-awarebasedmodulariza
103、tionhardwareandminimalistprotocol design are introduced to switch on/off functionalitiesaccording to traffic load conditions.When network is out-of-service,most hardware modules transit into deep sleep mode with almostno power consumption.As soon as a terminal detects traffic arriving,dormanthardwar
104、ewillresumerapidlytoprovidealmost22zero-latency loading,and ensure high quality of network service.The main challenge in this case is to completely redesign thehardware and software of the chip.5.4 Integrating with Other ApplicationsCommunication integrating with other applications is a kind ofeffic
105、ientwaytosaveenergy,whichcanachievedoubledachievementwithhalvedeffort.Forexample,visiblelightcommunication combines semiconductor lighting technology withoptical communication technology.Combined,the light-emittingdiodes(LEDs)light intensity is used for information modulation.Itneeds to overcome the
106、 problems of limited LED bandwidth,limitedcoverage,and susceptibility to interference.In addition,the scale ofnetwork nodes will grow sharply in the future.Free electromagneticenergy and friction power generation can also be employed asenergy sources to achieve coordinated transmission of informatio
107、nand energy and recycling energy saving.In terms of finding more resources,green new energy should bevigorously promoted.However,the new energy consumption rate islow,due to the problems of curtailment.In order to improve theutilization rate,it is necessary to build energy storage facilities.Many ba
108、se stations in mobile communications are located in top ofmountains and rural areas where new energy resources arerelatively abundant.Other than running base station directly by thenearby green energy,excess electricity can also be stored in backup23batteriesinthebasestation.Theintelligentendogenous
109、communication network can be integrated with the intelligentnetwork to maximize the utilization rate of green new energy.Compared with wind and solar energy,nuclear fusion is stable andenvironmentally friendly.It is considered to be the ultimate energysource that can solve human energy problems.The
110、difficulty ofachieving nuclear fusion lies in controllability.Controllable nuclearfusion methods include magnetic constraints,inertial constraints,gravitational constraints,etc.Magnetic constraints are close tosuccess under laboratory conditions,which is also the mainstreamresearch direction.But the
111、re is still a long way to go in terms ofcommercialization,andthereshouldbemorecontinuousexploration and breakthroughs.6.New Materials-the Basis for the Development of FutureInformation NetworksThe development of information and communication networks withhigherfrequencybandsandlowerEChasputforwardtr
112、ansformative demands for new materials.New antenna materials,new chip materials and new optical fiber materials have becomethree directions worthy of attention.246.1 Nanoprinted AntennaNanoprinting is an emerging technology for the preparation offlexible electronic devices by printing new materials
113、on differentflexible substrates.On a flexible fabric substrate,flexible wearablefabric antennas can be prepared by printing nano-conductiveparticles or coating conductive polymers according to the antennastructure.This makes flexible wearable communication systemspossible.Currently,printing electron
114、ic ink to prepare flexibleelectronic devices has become a new direction,but the printing inkmarket is less mature and requires huge amounts of polymericnanocomposites to assist development.6.2 Carbon NanotubeCarbon Nanotube(CNT)is an alternative to silicon transistorspotential technology for the pro
115、duct.At the same level ofintegration,carbon nanotube chips are smaller than silicon-baseddevices.Carbonnanotubeshave extremelyhigh toughness,strongerelectrical conductivity,shorter electrical signal transmission delay,high thermal conductivity,and low EC.In theory,compared withsilicon transistors wi
116、th the same characteristics,the energyutilization rate of carbon nanotube chips can be increased by 60%to 70%,the operating speed can be increased by 5 to 10 times,andthe power consumption can be reduced by 10 times.However,25large-scale production of high-purity and uniform carbon nanotubesand fixi
117、ng them on the substrate to make field effect transistorsaccording to the design requirements still face huge challenges.6.3 Anti-resonant Hollow FiberWith the explosive growth of information traffic,the inherentdefects of quartz as a fiber material gradually appear,such asnonlinearity,inherent time
118、 delay,limited bandwidth,maximumcapacity of single-mode fiber(bandwidth distance product),photo-induced damage,etc.barriers to technological development.New optical fibers such as hollow photonic crystal fibers,hollowanti-resonant fibers,few-mode fibers,and multi-core fibers havebecomeactivefrontier
119、researchfields.Amongthem,theanti-resonant hollow fiber has achieved breakthrough developmentin recent years due to its low loss and large bandwidth.In the future,itisanticipatedthathollowfibercanreducetheopticalcommunication delay by 1/3,and its ultra-low nonlinearity,largetransmission bandwidth win
120、dow and other characteristics areexpected to greatly increase the optical amplification distance andoptical system capacity.At present,the basic theories such as the light-guiding mechanism,bandwidth limit and loss limit of anti-resonator hollow fibers havenot yet been thoughtfully studied.The resea
121、rch of end-to-endanti-resonator hollow fiber communication system has just started.Thesubversivenewhigh-speedlong-distanceoptical26communication system based on hollow fiber needs to be exploredfrom scratch,and the industry chain needs to promote the researchof hollow fiber and its ultra-high-speed
122、long-distance opticalcommunication system.7.New Bionics-Combining Biology Technology and InformationTechnologyThe development of brain science and material science paves theway for fast progress of bionics in the field of information&communications and spawns two new directions:brain-inspiredcomputi
123、ng and DNA-based storage.7.1 Brain-inspired ComputingArtificial neural networks(ANN)was proposed in 1940s.The inputto each neuron in an ANN is a static electric signal.Its nonlinearresponses to excitations can be modeled by various nonlinearmappings.However,this is quite different from the transmiss
124、ionand processing of neural signals inside human brains which are inthe form of signal pulses.Compared to the cognitive process ofhuman brains,ANN merely utilizes some topology structures ofneurons,which is essentially the pile-up of digital logic gates.Manykey mechanisms of human brains are still u
125、nknown.27By further inspired by the bionics,models for neurons and synapsesthat are most closely resemble their biological counterparts havebeen proposed,the so called the third-generation neural networktechnology or brain-inspired computing.Its potential is huge:accurate modeling of space-time char
126、acteristics of biological signalswhere neural signal pulses are transmitted and processed.Thiswould drastically reduce the activity of neurons and ensurelow-energy consumption with high efficiency.By passing and distributing neural pulses across neurons andsynapses,brain-inspired computing can learn
127、 faster than deeplearning when it is used for characterization and signal processing.Hence,it is more suitable for high-efficient space-time signalprocessing and data mining.Brain-inspired computing has graduallyshown its benefits in the fields of intelligent decision-making,robot-control and comput
128、ational neurology.It is anticipated thatthe architecture and chips for brain-inspired computing will be oneof the key areas of computer architectures in post-Moore Era.Still there are several challenges for brain-inspired computing.Firstof all,the study is lack of basic support.Brain-inspired comput
129、ingrequires chips of special purposes,as well as a series of hardwareand software support that is based on neural science.Such chiparchitecture is based on new programable architecture that followsthe principles of neural science and has bio-neuron like analogcircuits to achieve fuzzy logic.This is
130、totally different from the28Von-Neumann architecture which is based on general-purposeprocessors and heterogeneous accelerators.In Von-Neumannarchitecture,memory and processors are separated,and the entiresystem operates with instruction flows.The study on brain-inspiredchips is still in its early s
131、tage,hampered by the lack of coredevices/materials and implementation complexities.While thegeneral processor-based simulator for brain-inspired computing canmitigate the deficiency of chips,the study and development of basicmodules is still in exploration stage and quite incomplete.Second,the human
132、 brains are not adequately understood andsimulated.Right now we can only achieve quite coarse simulation ofneural signal transmissions.There is still a long way to go inexploring how the information is transmitted,exchanged andintegrated via intricate coordination among hundred billions ofneurons in
133、side a brain.In addition,the study on brain-inspiredcomputing requires deep knowledge and expertise.Yet,such talentsare quite rare,not enough to hold up a big industry.7.2 DNA-based StorageEfficient data storage is an indispensable part of informationtechnology.Benefitingfromthefastdevelopmentinsemi
134、-conductor storage and magnetic storage,the data recordingdensity has kept growing at a pace similarly to Moores law.However,assemi-conductortechnologyisapproachingthequantum limit,it is necessary to look for alternative media to store29information,to meet the demands by the development ofinformatio
135、n technology.The idea of DNA-based storage wasproposed in 1960s,not long after DNA was found.After about 30years of a quiet period,the study on DNA-based storage hasbecome active,triggered by the projects of gene sequencedecoding.DNA-based storage is a way of information storage based on thebase seq
136、uences on the chromosomes of nucleus inside cells.Thereading and recording of base sequences on DNA segments are viathe chain reaction of polymerase.As the size of each DNA is atmolecular level,the information unit has two bits(A,G,T and C),and the structure of DNA is double helix and compressible,e
137、xtremely high storage density can be achieved within a very smallspace.Compared to the traditional solid-state memory devices andmagnetic disks/tapes,DNA-based storage has the advantage of lowpollution,light weight and organically degradable.Nevertheless,currently the data rate for the reading and r
138、ecording of DNA-basedstorage is very slow,much lower than that of solid-state devices ormagnetic based storage.Also it is quite expensive to prepare DNAsamples suitable for data storage and the cost of read/write is veryhigh.These challenges require breakthroughs in the fields of biology,chemistry,e

173、igh bar for vendors to participate.For example,the 3GPPoften takes 2 to 3 years for a given version of standard to completefrom its origination to finalization.It is hence extremely hard forsmall and medium enterprises to afford and follow through such along R&D cycle,except for a handful large oper
174、ators,globalequipment vendors,and chip manufacturers.Broad innovation istherefore hindered,preventing the growth and prosperity of theeco-system.In contrast,the modern IT industry leverages open source38communities to promote the creation and growth of eco-systems.Typically,open source projects evol
175、ves rapidly,and become the defacto standard after productization,which in turn pushes thestandard forward.Furthermore,widely used agile developmentmethods in R&D in recent years,along with various deploymentautomation,testingframeworks andtools,closed-loopdatautilization,life cycle management of AI/
176、ML algorithms and models,they together spawned a wild variety of software-defined modelsand eco-system.The adoption of the microservice architecture andthe momentum of cloudification have effectively helped thesoftwareandhardwaredecouplingandthesoftwaresegmentation.Combined with flexible APIs and SD
177、Ks provided bythe community,it sets a low bar so that start-ups,even individualdeveloperscanparticipateandcontributeinopensourcecommunity,resultingsignificantgrowthoftheeco-systems.Enterprises participating in open source and innovation can alsobenefit from faster go-to-market pace,forming positive
178、feedback tobuild up a healthy structure of the eco-system.The deep convergence of DICT also brings new challenges to thefuture information and communication industry and standardizationprocess.The synergy of the three is not only reflected in thetechnical perspective,but will also extend to others s
