I-LTE-M ne-NB-IoTAmanethiwekhi Endawo Ebanzi Yamandla Aphansi (LPWAN) athuthukiselwe i-IoT. Lezi zindlela ezintsha zokuxhuma zifika nezinzuzo zokusetshenziswa kwamandla okuphansi, ukungena okujulile, izici zefomu ezincane futhi, mhlawumbe okubaluleke kakhulu, izindleko ezincishisiwe.
Ukubuka konke okusheshayo
I-LTE-MimeleUkuvela Kwesikhathi Eside Kwemishinifuthi yitemu elenziwe lula le-EMTC LPWA (umshini othuthukisiwe wokuxhumana endaweni enamandla aphansi ebanzi) ubuchwepheshe.
I-NB-IoTimeleI-NarrowBand-Inthanethi Yezintofuthi, njenge-LTE-M, ubuchwepheshe bendawo obunamandla aphansi obuthuthukiselwe i-IoT.
Ithebula elilandelayo liqhathanisa izimfanelo ezibalulekile zobuchwepheshe obubili be-IoT futhi lisekelwe olwazini oluvelaUkukhishwa kwe-3GPP 13. Ungathola idatha evela kokunye ukukhishwa okufingqiwe kulokhuNarrowband IoT Wikipedia isihloko.
Ulwazi olungenhla luyisiqalo esingaphelele kodwa esiwusizo uma uzama ukunquma ukuthi i-NB-IoT noma i-LTE-M iyifanele kangcono iphrojekthi yakho ye-IoT.
Unalokho kubuka konke okusheshayo engqondweni, ake sijule kancane. Eminye imininingwane ngezici ezifana nokufakwa/ukungena, umhlaba, ukusetshenziswa kwamandla, ukuhamba, kanye nenkululeko yokushiya kuzosiza isinqumo sakho.
Ukuthunyelwa komhlaba wonke nokuzulazula
I-NB-IoT ingafakwa kuwo womabili amanethiwekhi e-2G (GSM) kanye ne-4G (LTE), kuyilapho i-LTE-M ingeye-4G kuphela. Nokho, i-LTE-M isivele iyahambisana nenethiwekhi ye-LTE ekhona, kuyilapho i-NB-IoT isebenzisaUkuguqulwa kwe-DSSS, edinga ihadiwe elithile. Zombili zihlelelwe ukuthi zitholakale ku-5G. Lezi zici, kanye nezinye, zinomthelela ekutholakaleni emhlabeni jikelele.
Ukutholakala komhlaba wonke
Ngenhlanhla, i-GSMA inesisetshenziswa esiwusizo esibizwa ngokuthiI-Mobile IoT Deployment Map. Kuyo, ungabona ukuthunyelwa komhlaba wonke kobuchwepheshe be-NB-IoT kanye ne-LTE-M.
Ama-opharetha ngokuvamile asebenzisa i-LTE-M kuqala emazweni asevele esene-LTE (isb., i-US). Kulula kakhulu ukuthuthukisa umbhoshongo okhona we-LTE ukuze usekele i-LTE-M kunokwengeza usekelo lwe-NB-IoT.
Nokho, uma i-LTE ingakasekelwa kakade, ishibhile ukubeka ingqalasizinda entsha ye-NB-IoT.
Lezi zinhlelo futhi kuhloswe ngazo ukuqwashisa abasebenzisi mayelana nokusetshenziswa kahle nokukhalipha kukagesi ngala mamitha.
