•2017: Dongosolo la 4G GSM la kanema latulutsidwa.
Dongosolo la intercom la 4G GSMKulowa ndi kutuluka ndikosavuta - ingoyimbani nambala ndipo chipata chimatsegulidwa. Kutseka makina, kuwonjezera, kuchotsa ndi kuyimitsa ogwiritsa ntchito kumachitika mosavuta pogwiritsa ntchito foni iliyonse. Ukadaulo wa mafoni am'manja ndi wotetezeka kwambiri komanso wosavuta kuyendetsa ndipo nthawi yomweyo umachotsa kufunikira kogwiritsa ntchito zowongolera zakutali zambiri komanso makadi ofunikira. Ndipo popeza mafoni onse obwera sayankhidwa ndi chipangizo cha GSM, ogwiritsa ntchito salipira ndalama zoyimbira. Dongosolo la Intercom limathandizira VoLTE, limasangalala ndi mtundu wabwino kwambiri wa kuyimba komanso kulumikizana kwa foni mwachangu.
VoLTE (Voice over Long-Term Evolution kapena Voice over LTE, yomwe nthawi zambiri imatchedwa high-definition voice, yomwe imamasuliridwanso kuti long-term evolution voice bearer) ndi muyezo wolumikizirana wopanda zingwe wa mafoni ndi malo osungira deta.
Imachokera pa netiweki ya IP Multimedia Subsystem (IMS), yomwe imagwiritsa ntchito mbiri yapadera ya Control plane ndi media plane ya voice service (yomwe imafotokozedwa ndi GSM Association mu PRD IR.92) pa LTE. Izi zimalola kuti voice service (control ndi media layer) ifalitsidwe ngati data stream mu LTE data bearer network popanda kufunikira kosunga ndikudalira ma voice network achikhalidwe osinthidwa.
Mphamvu ya mawu ndi deta ya VoLTE ndi yoposa katatu kuposa ya 3G UMTS komanso yoposa kasanu ndi kamodzi kuposa ya 2G GSM. Popeza ma header a VoLTE ndi ang'onoang'ono kuposa VoIP/LTE yosakonzedwa bwino, amagwiritsanso ntchito bwino bandwidth. 4G intercom system imalola zinthu za VoLTE. 1. Foni yam'manja iyenera kuthandizira VoLTE. 2. SIM khadi imathandizira VoLTE ndipo iyenera kukhala ndi wopereka chithandizo cha telefoni. 3.intercom system module ili ndi chonyamulira chothandizira
Kodi VoLTE ndi chiyani?
VoLTE (Voice Over LTE) imatumiza mautumiki a mawu kudzera pa netiweki ya LTE, zomwe zimathandiza ogwiritsa ntchito kusangalala ndi khalidwe lomveka bwino la kuyimba mawu.
