• 2017: 4G GSM video intercom system inobudiswa.
4G GSM intercom systemiri nyore kupinda nekubuda - ingo fonera nhamba uye gedhi rinovhurika. Kukiya sisitimu, kuwedzera, kudzima uye kumisa vashandisi kunoitwa nyore kushandisa chero foni. Tekinoroji yenharembozha yakachengeteka zvakanyanya uye iri nyore kubata uye panguva imwe chete inobvisa kukosha kwekushandisa akawanda, akakosha-akananga madhiraivha uye makadhi akakosha. Uye sezvo ese mafoni anouya asina kupindurwa neiyo GSM unit, hapana yekufona muripo kune vashandisi. Intercom system inotsigira VoLTE, inonakidzwa nekujeka kwekufona mhando uye nekukurumidza kubatana kwefoni.
VoLTE (Voice pamusoro peNguva Yakareba-Kushanduka kana Izwi pamusoro peLTE, rinowanzozivikanwa sezwi repamusoro-tsanangudzo, rinodudzirwawo semutakuri wezwi wenguva refu) ndeyekumhanya-mhanya isina waya yekutaurirana nharembozha uye data terminal.
Inobva pa IP Multimedia Subsystem (IMS) network, iyo inoshandisa purogiramu yakanyatsogadzirirwa yeKudzora ndege uye ndege yevhidhiyo yebasa rezwi (inotsanangurwa neGSM Association muPRD IR.92) paLTE. Izvi zvinobvumira iyo izwi sevhisi (kutonga uye midhiya layer) kuti ifambiswe sedhata dhata muLTE data mutakuri network pasina chikonzero chekuchengetedza uye kuvimba netsika yechinyakare inochinja izwi network.
Izwi reVoLTE nedata rakapetwa kanopfuura katatu iro re3G UMTS uye rakapetwa katanhatu iro re2G GSM. Nemhaka yekuti VoLTE packet headers iduku pane isina kugadziriswa VoIP/LTE, vanoitawo zvakanyanya kushandisa bandwidth.4G intercom system inogonesa mamiriro eVoLTE. 1.Nharembozha inofanirwa kutsigira VoLTE. 2.SIM kadhi inotsigira VoLTE uye inoda kuva nemupi wefoni. 3.intercom system module ine mutakuri wekutsigira
Chii chinonzi VoLTE?
