RedCap module Rx255C koob; Rau lub ob hlis ntuj 28, Tuam Tshoj Unicom tshaj tawm qhov uas qhia tawm ntawm neeg ntiaj teb thawj universal 5G RedCap coj mus muag module khoom NX307.

Raws li peb yeej paub, Nyob rau hauv tag nrho Internet ntawm tej yam kev lag luam, Lub cev ntawm mandrel manufacturers nyob rau hauv txoj kev ua lag luam saw hlau yog feem ntau txawm li tus prelude rau yavtom ntej yuav tsaws ntawm tej davhlau ya nyob twg thiab cov ntaub ntawv.
Ntua, Tuam Tshoj Telecom, Tuam Tshoj Unicom, Qualcomm, quectel, Zhilian, Lierda thiab lwm players loj players hauv txoj kev ua lag luam saw hlau muaj intensively tso hauv qoob loo-boosting xov xwm, Uas obviously ua rau qhov kev lag luam nrhiav lwm tus rau pem hauv ntej rau lub coj mus muag siv RedCap.

tiam sis, Muaj tug NB-IoT "Starfire" ua ntej, thiab LTE Cat.1 "lwj liam". Vim li cas yog RedCap tam sim no? Nws yuav ua li cas rau theem? Yuav ua li cas nws tsim afterwards? Muag nrog hauv teeb meem, Ntua, Zhicifang Internet ntawm tej yam think tank muaj launched hauv kev sib tham nrog tswv, Tub ntxhais mold manufacturers thiab kev lag luam alliances nyob rau hauv txoj kev ua lag luam saw hlau xws li Suav teb Telecom, Zhilianan, quectel, Lierda thiab 5G Internet ntawm tej yam kev lag luam Alliance, Thiab vam hais tias muab koj inspired.

5G teeb meem yuav lub sij hawm tuaj txog ntawm RedCap daws?

"Nyob rau hauv kuv lub tswvyim, RedCap yog zoo li ib yam khoom ntawm 3GPP 'kawg resort' rau 5G qauv." Qhov no yog Zhicifang tus intuitive impression ntawm RedCap thaum nws sib txuas lus nrog Xie Yunzhou, Secretary dav ntawm lub 5G Internet ntawm tej yam kev lag luam Alliance.

Txawm tias nws suab me ntsis helpless, Nws yog txaus saib qhov vam cia tso rau RedCap los ntawm qhov kev lag luam tseem saw hlau. Qhov tseeb, Yog peb txhais cov kab lus no kom meej meej, nws yuav tsum tau ntawd "Daim ntawv thov tam sim no thiab tag nrho ecological teev ntawm 5G yog nyob deb ntawm xeeb lub hom phiaj xav pom."

Txawm hais tias cov qeeb qeeb ntawm 5G daim ntawv teev yog txwv los ntawm ntau hom phiaj, Xws li lub teev ntawm network deployment, Lub pace ntawm technical txheem evolution, thiab cov pace ntawm upstream mandrel manufacturers...

Tab sis cov lus xaus saum toj no tsis yog cov lus ntawm Xie Yunzhou ib leeg. Nyob rau hauv tus txheej txheem ntawm kev sib txuas lus nrog cov neeg nyob rau hauv saw hlau, Yuav luag tag nrho tau zoo ib yam li views. Thaum nws tawm los rau qhov "culprit" Uas txwv txoj kev loj hlob ntxiv thiab nrov ntawm 5G, Sawv daws invariably ntsiab lus rau tus nqi tam sim no ntawm 5G.

Yao Lio, Senior khoom thawj coj ntawm Quectel Communications, Tseem hais Zhicifang uas raug nqi yeej ib txwm tau ib qhov teeb meem uas qhov kev lag luam muaj tau txhawj xeeb txog.

Raspberry Pi USB3.0 IoT Motherboard

Txoj kev loj hlob ntawm 5G yuav hais tias yuav tsum nyob rau hauv daim ntawv qhia txog viav vias hnub no, Tiam sis nws yog undeniable tias rau tej daim ntawv thov scenarios, Qhov huab kev kawm ntawm 5G theem teeb meem xws li nqi muaj cuam tshuam dab tsi rau nws txoj kev ua lag ua luam thiab daim ntawv thov kev pab, Thiab nws txoj kev loj hlob prospects muaj tau cuam tshuam dab tsi rau ib yam twg.

Qhov tseeb, ntxov 2020 mus rau 2021, Qhov kev lag luam saw hlau tau ua ib kev pom zoo-kom lub teev thiab txo tus nqi. Feem ntau hais lus, Feem ntau peb txoj kev mus cuag lub hom phiaj no: Thawj yog txhawb lub popularization ntawm tshuab tshiab los txhawb sawv daws siv los ntawm ib txoj cai foupective; Tus thib ob yog siv tswv li subsidies tsav lub enthusiasm ntawm tus industrial saw hlau thib peb yog innovate los ntawm ib tug pom kev pom, Xws li Cat.1 rau tej qhov nqaij ntuag 4G tej qhov nqaij ntuag, RedCap rau tej qhov nqaij ntuag 5G tej qhov nqaij ntuag, thiab lwm yam.

Txawm tias piv nrog rau txoj kev thib peb, Thawj ob txoj kev yuav cuag lub hom phiaj ntawm "Ua lub teev ntawm txoj kev ua lag luam thiab txo tus nqi", Tab sis kuv ntshai tias tsuas yog cov neeg koom muaj ib tug to taub txog lub ups thiab downs.

contrast, Txoj kev thib peb twb tau sim kom ntxov li ntuj 2021 thiab tau tiav zoo. lub sij hawm ntawd, Tuam Tshoj Unicom thiab ob peb manufacturers tso qhov kev lag luam tus thawj nqi tsawg 5G module - Yanfei 5G module. Yog ib lub highlights biggest highlights ntawm no module yog tias tus nqi xws li cov nyiaj ua se tau tsuas yog tsuas 499 neeg hais lus muag.

Qhia lub cev computing nrog raspberry pi thiab python

Yog vim li cas peb twb tau coj tus nqi ntawm 5G modules nyob rau hauv cov 500 yuan kos hauv cia li ob xyoos ntawm 5G siv yog tias Suav teb Unicom tau ua ntau innovations rau lub hauv paus ntawm general-purpose modules, Xws li txo yooj yim components thiab tsim cov nqi los ntawm tailoring, Tib lub sijhawm, txhim khu kev qha yog ua rau tej scenarios scenarios.

Nrog lub freezing ntawm tus txheej txheem RedCap, Tub ntxhais mold manufacturers yuav tau ntxiv thov nej tsam ces nqa tawm ntau streamlined tsim rau 5G terminals. Piv txwv, RedCap siv ib spectrum bandwidth, Thiab cov bandwidth hauv lub Sub-6GHz frequency qhab yog tsuas 20MHz, Thaum cov tsoos 5G yog 100MHz. 3GPP R18 ntxiv lub hom phiaj los txo nws bandwidth rau 5MHz.

Tsis tas li ntawd, RedCap muaj kuj txo cov transceiver antennas, txo tus xov tooj ntawm MIMO layers, Thiab nkag tau zog-txuag ntsuas xws li eDRX, li ntawd., Uas yuav pab cov tub ntxhais mold khoom mus ntxiv cuag lub hom phiaj ntawm tus nqi txo.

Piv txwv, Neeg ntiaj teb thawj tsawg-fais fab 5G RedCap positioning module khoom txiav txim los ntawm Suav teb Telecom Tianyi IoT thiab tub ntxhais mold manufacturers Zhilianan thiab Lierda lub sij hawm no yog raws li tus 3GPP R17 low-power high-precision positioning specification thiab adopts ib zaug xwb tsim.

Ntawm no tsis nyob ntev, lub hom phiaj ntawm lub hom phiaj 5G module xav tau 400 mus rau 500 yuan txawm tom qab subsidy thiab nqe txo. tiam sis, Raws li cov kev paub txog peb lub luag hauj lwm ntawm Zhici, Tus nqi ntawm lub RedCap positioning nti tsim thiab manufactured los Zhilianan yog tam sim no tsuas 5G txawb xov tooj txawb tej daim rau lub lag luam. ib-tenth ntawm tus nqi.

Tau mas, Ntxiv rau txo tus nqi ntawm tus module xwb, the industry chain is also promoting the reduction of the overall cost of 5G and RedCap in other ways. Piv txwv, Quectel provides supporting services such as machine design consultation, hardware testing, and machine certification services, thiab lwm yam. , from the side to reduce the cost of commercialization of the customer's complete machine.

While providing overall technical solutions, Lierda is promoting close cooperation with surrounding suppliers, establishing a complete supply system based on RedCap, and promoting products at the module level to quickly enter the expectations of industry customers by improving the integration of the industrial chain. scope.

Tian Zhiyu, manager of Lierda's 5G business department, told Zhicifang that with the increase in the popularity of RedCap, the price of modules will continue to approach the price of 4G modules in the future, which will further support 5G application innovation.

But at the same time, he also emphasized that if RedCap only has an advantage over the current 5G module price, it may not be widely accepted by the market, and the industrial chain will not be able to "stable and long-term". The more important advantage of RedCap lies in its new 5G features. , which can meet the needs of vertical applications in thousands of industries.

What impact has RedCap had on IoT?

If the high price is only the "surface" that reflects the problem, then the value mismatch between supply and demand is the "Hauv" of the problem.

The biggest difference from previous network deployments is that the Internet of Things is highly fragmented. The application scenarios of the Internet of Things are complex, and the demands of various industries and even individual customers are also different, which leads to different requirements for actual users on the network indicators. This has also been confirmed in the conversations between Zhicifang and industry insiders—everyone mentioned that there is a mismatch between network speed and scene requirements in actual scenarios.

Piv txwv, in a highly automated smart factory, although 5G's ultra-large bandwidth, ultra-low latency and high reliability can meet the needs of precise control of industrial robots.

tiam sis, there are often a larger part of the equipment in the factory that does not use the high rate of eMBB, such as video transmission, industrial sensing equipment, li ntawd, thiab thiaj li. Tib lub sijhawm, these devices often require higher performance than mMTC (NB-IoT and eMTC), and lower latency connection support than 4G networks.

Carriers are one of those who benefit from being inspired by RedCap. Wang Zhicheng, director of China Telecom's Internet of Things Open Laboratory, believes that promoting RedCap applications can not only reduce the cost problems faced by 5G applications, but the more important aspect is to realize its value and fully integrate it into UC in various industries. And this will eventually lead to the real transformation of the role of operators in the era - from "operators' Internet of Things" mus rau "operators of the Internet of Things".

Piv txwv, the three major operators are now expanding their customized network services. According to the traditional thinking of network construction and delivery, most of the projects can only stay at the "network construction" Tshooj. Once the network is built, it means that the entire service In the end, there may not actually be an intersection with the client's business.

As for digital empowerment, operators not only need to coordinate network deployment, but also need to consider deeply integrating their own CT capabilities with customers' OT services, so as to truly embed them in vertical industries.

The promotion of RedCap will prompt operators to change their thinking. Through the China Telecom Capability Rubik's Cube platform and RedCap, customized services will be proposed, and specific industry application scenarios will be selected one by one, and the uplink and downlink, time delay, jitter and The positioning accuracy and other requirements are strictly and accurately defined, so that this 5G customized network can more accurately meet the needs of vertical industries. Behind this is not only simple product provision, but also a series of tasks such as operation and maintenance, kev pab, customer service, and the launch of the industrial chain.

Tau mas, based on the characteristics of the Internet of Things and the premise of large-scale network connections, operators not only need to break up the entire Internet of Things, but also need to integrate the needs of the same industry, find the greatest common divisor, and provide relatively standardized atomic ability. Thaum tam sim no, China Telecom has carried out scenario verification based on RedCap for the five major industries of port, fais fab tuag, steel, mining and chemical industry, laying the foundation for the deployment of RedCap as soon as possible.

yav tom ntej, such benefits will continue to be transmitted to all parties in the industry chain. Operators, khoom manufacturers, terminal manufacturers, and application integrators will cooperate more and more closely and continue to penetrate into vertical industries. Create and interact.

Yao Li told Zhicifang that each industry and each type of product has its own demand characteristics for accessing the network. The efforts of operators and mandrel manufacturers will continue to promote RedCap from "usable" mus rau "yooj yim", and finally pass the The refined design works better on the 5G To B ecosystem.

What kind of attitude will RedCap develop?

Thaum tam sim no, the industry has already summarized the pyramid demand model of "high, medium and low" three different categories of rates of "10%-30%-60%" for the Internet ntawm tej yam, and reached a consensus. The cellular IoT technologies represented by NB-IoT and Cat.1 rely on mature technologies and industrial chains, and have an annual growth scale of hundreds of millions of connections in China. Yog li ntawd, vim, this has also caused a little concern in the industry about the development of RedCap.

Qhov tseeb, for each technology, based on the different classes it serves and the industry applications it applies to, it will also have its own unique living space, which is the premise of each new technology. What's more, RedCap also has a big killer feature - 5G native features, which is a capability that NB-IoT, Cat.1 and even 4G do not have, which also makes RedCap have basic advantages in many industry application scenarios.

Piv txwv, in the power grid environment, RedCap can support differential protection with uRLLC ultra-low latency; while in a separate industrial park or smart factory, based on the requirement that the data does not leave the park, RedCap cooperates with the 5G lwm network UPF sinking solution to be able to operate on 5G When a network is deployed, a mode of isolation from the outside world is established to ensure data security - these are not available in 4G.

Tsis tas li ntawd, RedCap is also adding new features to further meet the challenges faced in actual application scenarios. Piv txwv, add positioning function.

5G RedCap succeeded? Nws yuav tam sim no?

In the R17 standard, the positioning accuracy target has been further improved from 3 meters indoors and 10 meters outdoors to the sub-meter level, and the positioning delay requirement is less than 100ms; in the industrial Internet of Things scenario, the positioning accuracy error of R17 is required to be less than 20cm.

Wang Zhijun, senior vice president of marketing and sales of Beijing Zhilian Technology Co., ltd., told Zhicifang that in fact, in 5G To B projects, the demand for positioning on the terminal side is stronger, and the number is also larger. The RedCap based on 5G characteristics will turn the "dumb terminal" in the IoT terminal into a "terminal that can speak".

From the current point of view, the positioning market is already a state of contention among a hundred schools of thought, and there are different positioning service solutions for indoors and outdoors. Piv txwv, outdoors, the technology based on satellite positioning has long been mature and has been widely used. Indoor Bluetooth AoA positioning, UWB positioning and other technologies have also attracted attention along with market demand and application innovation.

But from the current point of view, both indoor and outdoor positioning still cannot achieve the coverage of one network, and it needs to be realized by integrated positioning technology, such as GNSS+Bluetooth AoA or GNSS+Wi-Fi. When the application scenario has data transmission requirements such as returning location information, it is also necessary to bind other communication technology solutions, such as the positioning method of Bluetooth AoA+4G fusion, of which 4G can be used for information transmission.

tiam sis, if 5G ready is taken as the premise, the problem of indoor and outdoor positioning connection can be easily solved by deploying a 5G network, thiab tib lub sijhawm, there is no need to add other auxiliary technologies for communication. Tsis tas li ntawd, 5G-based positioning will greatly reduce deployment costs, because ready-made 5G indoor and outdoor base stations can be reused without repeated network deployment and site construction, avoiding a large amount of labor cost investment. Thaum kawg, a large number of energy-saving technologies introduced by RedCap will realize the low power consumption requirements of 5G positioning, which will also reduce a large number of subsequent operation and maintenance costs.

What kind of commercial rhythm will RedCap present?

There is no doubt that 2023 will be the first year of commercial use of RedCap. Wang Zhicheng told Zhicifang that the commercial development of RedCap should be faster than expected. According to previous industry estimates, the release of RedCap will probably wait until 2024, but from the market point of view, it has clearly exceeded this expectation, and judging from the current pilot and customer response, it will even be more optimistic than this speed.

Yog 5G RedCap txawv teb chaws los yog suav?

In terms of chips, Zhilianan will mass-produce 5G RedCap high-precision and low-power positioning chips in the third quarter of this year. Starting from April, it will conduct small-batch experiments in several typical B-end scenarios. Do sample deployment, and then carry out large-scale shipments after testing and debugging.

yav tom ntej, in the middle of 2024, Zhilianan will also develop software for the digital transmission function of RedCap, so as to truly realize the integrated capability of chip positioning + kev sib txuas lus. Thaum tam sim no, Zhilianan is actively cooperating with the three major operators, following the implementation of the operator's 5G private network, and ultimately driving the promotion and popularization of RedCap from point to surface.

In terms of modules, Quectel has officially released its Rx255C series of 5G modules in early 2023, and has designed two versions including RG255C and RM255C for the global market. Thaum tam sim no, this series of products is in the stage of intensive R&D and perfection.

It is expected that the first batch of module engineering samples will be provided in the second quarter of this year for testing by customers in vertical industries. It will officially enter the commercial stage by the end of this year, fully meeting the market demand for RedCap.

In terms of Lierda, Ntxiv rau kev koom tes nrog Zhilianan los tsim 5G RedCap high-precision thiab tsawg-fais fab txoj hauj lwm modules, Nws yuav tau tsom ntawm txoj kev tshawb fawb thiab kev loj hlob ntawm RedCap modules nrog cov transmission functions, Thiab yuav tsum tso engineering samples kawg ntawm xyoo no.

tiam sis, Txawm hais tias qhov kev lag luam hu rau coj mus muag siv RedCap yog maj mam qhia, Nws tseem yuav tsum tau saib rationally. Tian Zhiyu hais tias lub suab txhais tau hais tias qhov kev lag luam muaj rua redCap, Uas yog tus tsav quab yuam ua qhov kev lag luam rau pem hauv ntej, Tab sis tej kev lag luam yuav tsum tau sij hawm mus cultivate, Tshwj xeeb tshaj yog nyob rau hauv daim teb industrial teb.

IOT Raspberry Pi

Raws li ntau lawm kev ruaj ntseg ntau lawm yuav tsum tau, Nyob rau hauv cov ntaub ntawv upgrade ntawm lub teb industrial teb, Nws ua tau yuav siv sij hawm ntev los xyuas los ntawm cov khoom qhia los teev tawg. Txawm nyob hauv lub automotive teb, lub voj voog yuav ntev dua, feem ntau nyob ib ncig ntawm 2 Xyoos.

Raws li txoj cai ntawm network intergenerational upgrades, kab tias ib hnub yav tom ntej, 4G tes hauj lwm yuav usher hauv "glorious laus". Ua ib feem tseem ceeb ntawm lub kaw lus 5G, RedCap no kuj xav pom kom siab undertake qhov tseem ceeb ntawm kev cob cog rua nruab nrab thiab high-speed scenarios. Peb tseem tsis tau qhia thaum hnub ntawd yuav, los sis txawm nug seb nws yuav tuaj. Tiam sis nws yog conceivable tias RedCap yuav "continuously loj hlob thiab tawg thaum twg los tau".

Yog 5G RedCap txawv teb chaws los yog suav?

Tuam Tshoj Unicom muab cov hlau lead hauv tsim kom muaj txoj kev lag luam tus thawj 5G RedCap kev lag luam alliance.
Qhov kev lag luam alliance yog coj los ntawm Suav teb Unicom thiab ua yeem los ntawm Suav teb Huadian Corporation Tianjin Branch, COOEC, Huawei thiab lwm enterprises. Nws yog ib lub koom haum industrial integrating pab neeg, professionalism thiab kev lag luam.
