Long Range Ethernet Rs232 Wireless Data Transceiver Modules Video Bridge

long range wireless ethernet bridge rj45 rs232/485 two way data video transsceiver

TDD-COFDM is our new NLOS(non-line of sight) two-way data transmission system and wireless mobile emergency communication private network, which is independent of telecom operators wireless network. 

Its confidentiality,security, mobile performance are better than Telecom operators. Also, it is a fully transparent data encryption transmission emergency security network. 

TDD-COFDM multiplexing technology to channel resources in time through time slot, frequency through a large number of sub carriers to flexibly allocated to multiple users, and in a single frequency to maximize the realization of multi user access. 

System occupy relatively narrow-band air frequency (4/8MHz)and strong anti-multipath interference ability to overcome simulation technique and the high-speed mobile data transmission under multipath reflections and nuisance caused by occlusion, then achieved in a complex environment transfer: data packing form, audio and video data, serial asynchronous data, Miniature volume, precision design, lightweight and easy to carry that commonly used in short distance high speed wireless data transmission and on air long distance high speed wireless data transmission purposes.

Features of TDD-COFDM wireless transceiver

1. Advancement: TDD-COFDM channel modulation technology, support fast-moving,ultra-wide band, and fully transparent transmission.

2. Security: private network, private communication transport protocol, sole synchronization code and AES encryption. and also customer manually customize the secret key
