I-LTE-M kunye ne-NB-IoTNgamandla oMbane oBanzi weeNdawo zoThungelwano (LPWAN) eziphuhliselwe i-IoT. Ezi ndlela zintsha zonxibelelwano ziza kunye neenzuzo zokusetyenziswa kwamandla aphantsi, ukungena nzulu, iifom ezincinci kwaye, mhlawumbi okona kubaluleke kakhulu, iindleko ezincitshisiweyo.
Isishwankathelo esikhawulezayo
I-LTE-Mimele iIxesha elide lokuzivelela koomatshinikwaye ligama elenziwe lula le-EMTC LPWA (uhlobo lonxibelelwano lomatshini ophuculweyo lommandla obanzi wamandla aphantsi) ubuchwepheshe.
I-NB-IoTimele iNarrowBand-Intanethi yezintokwaye, njenge-LTE-M, bubuchwephesha bendawo ebanzi yamandla aphantsi obuphuhliselwe i-IoT.
Itheyibhile ilandelayo ithelekisa iimpawu eziphambili zeetekhnoloji ezimbini ze-IoT kwaye isekwe kulwazi oluvela3GPP Ukukhutshwa kwe-13. Ungafumana idatha kolunye ukhupho olushwankathelweyo kuleNarrowband IoT Wikipedia inqaku.
Olu lwazi lungasentla aluphelelanga kodwa luluncedo lokuqala ukuba uzama ukwenza isigqibo sokuba ingaba i-NB-IoT okanye i-LTE-M iyilungele na iprojekthi yakho ye-IoT.
Ngaloo magqabantshintshi akhawulezayo engqondweni, masingene nzulu nzulu. Olunye ulwazi olongezelelekileyo ngeempawu ezinje nge-coverage/ukungena, ihlabathi, ukusetyenziswa kwamandla, ukushukuma, kunye nenkululeko yokushiya kuya kunceda isigqibo sakho.
Ukusasazwa kwehlabathi kunye nokuzulazula
I-NB-IoT inokuthunyelwa kwiinethiwekhi zombini ze-2G (GSM) kunye ne-4G (LTE), ngelixa i-LTE-M i-4G kuphela. Nangona kunjalo, i-LTE-M sele ihambelana nenethiwekhi ye-LTE ekhoyo, ngelixa i-NB-IoT isebenzisaUkumodareyitha kweDSSS, efuna ihardware ethile. Zombini zicetywa ukuba zifumaneke kwi-5G. Ezi zinto, kunye nezinye, zinefuthe ekufumanekeni kwihlabathi jikelele.
Ukufumaneka kwehlabathi
Ngethamsanqa, i-GSMA inomthombo oluncedo obizwa ngokuba yiImephu yokuhanjiswa kwe-IoT yeselula. Kuyo, unokubona ukusasazwa kwe-NB-IoT kunye ne-LTE-M kwihlabathi jikelele.
Abanini-zithuthi basasaze i-LTE-M kuqala kumazwe asele ene-LTE (umz. e-US). Kulula kakhulu ukuphucula inqaba ekhoyo ye-LTE ukuxhasa i-LTE-M kunokongeza inkxaso ye-NB-IoT.
Nangona kunjalo, ukuba i-LTE ayixhaswanga, kuyabiza ukubeka isiseko esitsha se-NB-IoT.
La manyathelo anenjongo yokwazisa abasebenzisi malunga nokusetyenziswa kombane ngokufanelekileyo nangobuchule ngezi mitha.
