Stable Wireless Signal WIFI GDCBT400W For Digital TV , 12VDC / 500mA

Overview

GDCBT400W EOC slave with wifi (based on AR7411 chip) is a kind of coaxial cable two-way system accessing devices, which provides 4 Ethernet ports, and wireless WIFI function.adapting point to multipoint transmission way between master and slave equipment, it assures many people can enjoy fast transmission speed at the same time.

? ?

Slave equipment merge relatively low speed parallel modulation data streams which are demodulated by master equipment ?into a high-speed serial data stream, finally, decrypting data into the standard Ethernet signal for the user data terminal (PC, IPTV set-top boxes, IP voice gateway )etc.

? ?

Wifi function conforms to IEEE802.11 B/G/N protocol,IEEE802.11 I security protocol, as well as the IEEE802.11 protocol, and it can interconnected with other wireless devices conforms to the same standard.Supporting the latest 64/128 WEP encryption, and the WPA-PSK/WPA2-PSK,WPA/WPA2 security mechanism.Its wireless transmission rate can up to 150 mbps which can adapt to different working environment,and make a desktop or laptop computer and other devices need wireless easily access wireless network.

? ?

The slave equipment supports remote management and can operate master equipment through SNMP/WEB ?to achieve management and Settings to under slave devices .It provides 320 MBPS access bandwidth on coaxial network , occupying 7.5 MHz-65 MHz low frequency band, effectively avoiding conflict with the frequencyof the existing CATV system occupying ,and reducing the interference between each other. Besides, it supports tree-type and star-type CATV network with long transmission distance, good network adaptability and high bandwidth ,is a powerful weapon in radio and television system deploying the data network.
