NB-IoT ikhala chisankho choyambirira cha mapulogalamu a LPWAN munthawi ya 5G

NB-IoT idayamba "kupititsa patsogolo".

Kuyambira kukhazikitsidwa koyamba kwa NB-IoT mu 2015, NB-IoT idakumana ndi kuzizira kwa 2016, yankho la 2017 lakonzeka, ndipo kukhwima kwa chilengedwe kwa 2018 ndi magawo angapo. Cao Ming, wachiwiri kwa purezidenti wa mzere wopanga ma waya wa Huawei, adati NB-IoT ilowa bwino pamalonda pa 2019 a NB-IoT "mamiliyoni 100" oyendetsa zachilengedwe. Pali ma network amtundu wa 89 NB-IoT padziko lapansi. Ndi mitundu yopitilira 180 ndi kulumikizana kwina pafupifupi mamiliyoni 70, NB-IoT yakhala njira yabwino kwambiri padziko lonse lapansi, yomwe ikudziwika kwambiri komanso ndiukadaulo wa LPWA.

Cao Ming adatinso pakupanga makampani a NB-IoT, Huawei ndiwotsatsa wodalirika wa makampani a NB-IoT, ndipo akupitilizabe kupititsa patsogolo msika wa NB-IoT mokhudzana ndi mayankho ndi chilengedwe. Pankhani ya mayankho, Huawei ndiye otsogolera omwe akutsatsa mayankho omaliza a NB-IoT kuchokera ku tchipisi ndi zida zamtaneti kupita ku nsanja ya mtambo ya IoT.

Cao Ming adawonetsa kuti zaka zitatu zapitazo, Huawei adayambitsa Chip cha NB-IoT, Boudica 120, chomwe chidayambitsa kwambiri njira yamalonda ya NB-IoT. Mu 2018, Huawei adapanga chipika cha Boudica 150, adathandizira protocol R14, adathandizira ma frequency band angapo, ndipo magwiridwe adayandikira. GPRS imakulitsa bwino malo a NB-IoT. Pofika chaka cha 2020, Huawei akhazikitsa pulogalamu ya Boudica 200, yomwe imathandizira protocol ya 3GPP R14 / R15, kuphatikiza kwakukulu, chitetezo komanso kutseguka. Kugwiritsa ntchito magetsi pazomwe zikuchitika kumatha kuchepetsedwa ndi oposa 40%. Kugwiritsa ntchito kwa Boudica 200 kupititsa patsogolo Kupititsa patsogolo kulumikizana kwa masiteshoni a NB-IoT.

Pa netiweki, nsanja komanso chilengedwe, Huawei amakhalanso akuyesetsa.

Pa msika wa maukonde, Huawei amatsata kusintha kwa protocol ndikupitilizabe kupitiliza mapeto ake. Mtengo wa R14 uplink wafika pa 150Kbps. Poyerekeza ndi ukadaulo wa GPRS IoT, kuchedwa kwa R15 / R16 ndikugwiritsanso ntchito magetsi kumachepetsedwa, ndipo mtunda wophimba ungafikire ku 120KM. Pofika nthawiyo, chiwonetsero cha kuthandizira kwa NB-IoT chikhala chambiri.

Pa nsanja ya mtambo, yokhazikika pa nsanja ya mtambo wa OceanConnect IoT, Huawei akhoza kupereka chithandizo chazomwe chimakhala chodzaza ndi mizinda yanzeru, kugwiritsa ntchito intaneti, malo ophunzirira anzeru komanso mafakitale ena. Ili ndi cholumikizira cha biliyoni ndi kuthekera kwamilingo imodzi. Kusintha kwake kumaphatikizapo NB-IoT. Ma intaneti ambiri, ma protocol ambiri komanso mitundu ingapo yamafakitale kuphatikiza 5G aphatikiza kale chilengedwe cha mafakitale opanga 50+ ndi othandizana nawo 3000+.

Makamaka pankhani yachilengedwe, Cao Ming adanenanso kuti mu 2016, Huawei adapanga koyamba Openlab, popereka mautumiki monga kapangidwe ka mayankho, kuphatikiza mayankho ndi chitsimikiziro chaukadaulo kwa abwenzi a IoT. Pakadali pano, yakwanitsa kugwira ntchito zopitilira 40 kuchokera ku Openlab. . Nthawi yomweyo, Huawei adakulitsa mphamvu zachilengedwe za NB-IoT pogwiritsa ntchito mgwirizano wamakampani, mabungwe azogulitsa ndi mabungwe ena kuti alimbikitse kugwiritsa ntchito ukadaulo kwa ukadaulo wa NB-IoT m'mafakitale osiyanasiyana. Pakadali pano, pali mamembala 2 500 oyambitsa NB-IoT Alliance omwe adalembetsedwa mu GSMA, akupanga makampani 1,500. Mothandizidwa ndi mabungwe azogulitsa mafakitale, NB-IoT yaphatikizidwa pamiyeso yamakampani a zamadzi, gasi, kuyatsa mumsewu, chitetezo chamoto, ndikuwunikira pakagwa tsoka. Mwa iwo, kuchuluka kwa kulumikizana m'madzi, gasi ndi mafakitale ena wafika 10 miliyoni. Potsatila, Huawei adzaonjezera kukhazikitsa kwa chilengedwe cha NB-IoT GLocal (Global + Local), kukopera zomwe zinachita bwino ku China NB-IoT kutsidya lina, ndikukulitsa limodzi ntchito zakunja ndi antchito apakhomo achi China.

Monga tonse tikudziwa, malonda a 5G afika. Munthawi ya 5G, ndalama zogwiritsira ntchito ma network ambiri zidzakhala katundu waukulu kwa ogwiritsa ntchito. Pofuna kupititsa patsogolo magwiridwe antchito, 2G ndi 3G pang'onopang'ono imachoka mu netiweki, ndipo kusunthira kowoneka bwino kupita ku 4G kakhala kachitidwe ka nthawi. Maukonde chandamale cha nthawiyo adzakhala 4G + 5G. Cao Ming adatsimikiza kuti opanga opitilira 20 padziko lonse lapansi atseka ma network a 2G, ndipo ogwira ntchito ku China akukonzekera kubwereranso ku 2G / 3G network. Chifukwa chake, makampaniwo azindikira kale kusintha kwaukadaulo uku, ndipo agwiritsa ntchito ukadaulo wa NB-IoT kupanga ma termoals a IoT. Chaka chino, kuchuluka kwa kulumikizidwa kwatsopano ku NB-IoT ya China kwadutsa 2G.

Mu Julayi chaka chino, nthumwi zonse za ku China komanso 3GPP zidatumiza NB-IoT ngati ukadaulo wa 5G ku ITU (International Telecommunication Union), zomwe zikutanthauza kuti NB-IoT ikhala gawo la ukadaulo wa 5G. Makina a NB-IoT omwe adayikidwa pakadali pano amatha kulumikizana ndi netiweki ya 5G nthawi zambiri mawonekedwe ataperekedwa kwa 5G NR (mawonekedwe atsopano a mpweya) mtsogolo. Cao Ming pomaliza ananena kuti mgwirizano wa R16, womwe udzagundidwa mu Marichi 2020, sudzatanthauzira njira yatsopano ya 5G LPWAN. NB-IoT ikhala chisankho choyambirira cha mapulogalamu a LPWAN munthawi ya 5G. Mayendedwe onse amoyo amatha kugwiritsa ntchito bwino chilengedwe cha NB-IoT, kuyendetsa patsogolo makinema, ndikukhala ndi mwayi mu nthawi ya 5G Internet ya Chilichonse.
