YiniI-LTE Band 31 450MHz Isiphinda?
I-LTE450, eyaziwa nangokuthi i-band 31, iyizinhlelo zokusebenza zenethiwekhi yangasese ye-LTE esebenzisa i-450Imvamisa ye-MHz.
Amanethiwekhi ezokuxhumana e-Long-Term Evolution (LTE) asebenzisa amabhendi efrikhwensi amaningana, i-Band 31, FDD, 450, NMT, 452.5 – 457.5, 462.5 – 467.5 .
Umehluko osobala kakhulu ku-LTE 450 imvamisa yayo ephansi, ku-450 MHz.Amanethiwekhi omphakathi ajwayelekile anefrikhwensi engu-900, 1800, 2100 noma 2600 MHz.Imvamisa ye-LTE 450, noma ibhendi 31 njengoba yaziwa kanjalo ngezinye izikhathi, idinga imojula ye-LTE 450 ezinikele.Lokhu kunikeza ngokushesha i-LTE 450 inzuzo mayelana nokuminyana kwesignali okuncane.
I-LTE 450 yona ngokwayo iyinethiwekhi yokuxhumana engenantambo esekelwe kumafrikhwensi angu-450 MHz.Okubaluleke nakakhulu, ibhande lenethiwekhi elinikeza ukufinyelela okubanzi, ukungena kwesignali ejulile, isivinini esikhulu nokuxhumeka okuvikelekile, okuthembekile.
I-Kingtone Nikeza Izindleko Ezisebenza Kakhulu Ukusebenza Okuphezulu Kwangasese kwe-LTE Inethiwekhi ye-FDD LTE Ibhendi engu-31 450MHz Isiphindaphinda Esikhethiwe Sebhendi Yangaphandle, wamukelekile umbuzo wakho!
Izici Eziyinhloko
◇ I-PA ephezulu yomugqa;Ukuzuza kwesistimu ephezulu;
◇ Intelligent ALC ubuchwepheshe;
◇ I-duplex egcwele kanye nokuhlukaniswa okuphezulu kusuka ku-uplink kuya ku-downlink;
◇ Ukusebenza okuzenzakalelayo ukusebenza okulula;
◇ Isu elihlanganisiwe elinokusebenza okuthembekile;
◇ Umkhawulokudonsa ungalungiselelwa ukusuka ku-5-25MHz kubhendi yomsebenzi.
◇ Ukuqapha kwendawo nokukude (ongakukhetha) nge-alamu yephutha elizenzakalelayo &isilawuli kude;
◇ Idizayini evikela isimo sezulu yokufakwa kwesimo sezulu sonke;
