the 2G/3G is still mainly using, 4G LTE is also coming now!
SEM.Test, as a famous band in the telecom test lab, we'd stated the 4G LTE Automatic test system.
We can provide the test and certification for 2G, 3G, 4G LTE for the applicants for their rapid response to the market in time.
一、4G LTE mainly specificatioin
Mostly 4G LTE product contained Mobiles, MID, 4G LTE data moduler and also contained 2G and 3G.
4G LTE's working Modes:
FDD-LTE --- for American and EU
TDD-LTE --- for Asia such as China Mobile and China Unicom
4G LTE has many channel that FDD-LTE (Band 1 ~ Band 25),TDD-LTE(Band 33 ~ Band 43)。Most 4G product contains 3个Band,some other has 4-5个Band。
二、4G LTE Test standards:
(1) EU R&TTE
