Waa maxayKooxda LTE 31 450MHz?
LTE450, sidoo kale loo yaqaan band 31, waa codsiyo shabakad LTE gaar ah oo isticmaalaya a450Inta jeer ee MHz.
Kobcinta Muddada Dheer (LTE) ee shabakadaha isgaadhsiinta waxay adeegsadaan dhawr xabbo oo soo noqnoqda, Band 31, FDD, 450, NMT, 452.5 – 457.5, 462.5 – 467.5.
Farqiga ugu muuqda ee LTE 450 waa inta jeer ee hooseeya, oo ah 450 MHz.Shabakadaha caadiga ah ee dadweynaha waxay leeyihiin soo noqnoqoshada 900, 1800, 2100 ama 2600 MHz.Inta jeer ee LTE 450, ama band 31 sida mararka qaarkood loo yaqaan, waxay u baahan tahay module LTE 450 gaar ah.Tani waxay isla markiiba siinaysaa LTE 450 faa'iido marka la eego ciriiriga calaamadaha yar.
LTE 450 lafteedu waa shabakad isgaarsiin wireless ah oo ku saleysan inta jeer ee 450 MHz.Waxa ka sii muhiimsan, waa koox shabakad ah oo bixisa gaadhis ballaadhan, gelid calaamad qoto dheer, xawaare sare iyo isku xidh ammaan ah oo la isku halayn karo.
