Product Description

T321S-400 TDD SD Transmitter 1W Same Frequency Network

Introduction:

Time Division Duplexing (TDD) is a communication technique allowing for two-way communication within the same frequency band by alternating the transmission times of a device. An important parameter for devices in these TDD-transmission systems is the transient response of the adjusted carrier feedthrough when the devices are rapidly turned on and turned off. When a device transitions to the active transmitting state, quickly achieving and maintaining the lowest adjusted carrier-feedthrough levels possible is important. Quickly achieving the lowest adjusted carrier-feedthrough levels keeps the carrier signal from masking the desired information and allows for greater available transmission time.

Features:

1. Modularity , Three security , Low-power electronics ;
2. Support the system build network within same frequency or different frequency , automatic roam ;
3. Power stability, adjustable dynamic power ;
4. The wireless channel adopt either AES128 encryption ;
5. IP Non line-of-sight transparent data transmission ;
