5W TDD - OFDM Portable Base Station for Commanding Centers

Introduction:

The other system uses only a single frequency and it shares the channel between transmission and reception, spacing them apart by multiplexing the two signals on a time basis. Time Division Duplex, TDD, is used with data transmissions (data or digitised voice), transmitting a short burst of data in each direction. As the transmission periods are relatively short no time delay is noticed on voice transmissions resulting from the time delays introduced by using TDD.

Product Features:

Inserted modular functionalized, data transmission and display integration Stable power and adjustable dynamic power Support 8 channel video decoding, built-in soft matrix, data storage Single carrier frequency support up to 4 simultaneous users two-way data transmission Encryption: AES 128 bit, flexible power supply Built-in microphone for phone talk and PTZ control.
