GDCBT400WB series EOC Slave with WIFI


Overview        GDCBT400WB EOC slave with WIFI 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 frequency of 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. Features         Providing four standard Ethernet interfaces
        Stable wireless signal, strong penetrating power
        Following IEEE802.11 B/G/N and IEEE802.11 I security protocol
        Supporting the latest 64/128 WEP encryption and the security mechanism of WPA-PSK/WPA2-PSK and WPA/WAP2
        Wireless transmission rate can up to 150 Mbps
        Providing one independent EOC channel (one CATV output, the other CATV + data input)
        high frequency spectrum use ratio, nearly twice higher than than the serial system, which has strong competitiveness in the cable television transmission environment with limited resource of frequency spectrum.OFDM signal of adjacent sub-carrier overlap, theoretically their frequency spectrum use ratio is close to the limit.
        Possessing strong anti-jamming capability, stable performance. The OFDM system to spread out the data into many sub-carrier, and greatly reduces the symbol rate of each sub-carrier to abate the effect of multi-path propagation. If adding cyclic prefix as a means of interval protection ,users can even eliminate inter-symbol interference.
        It can select automatically the best way of modulation and frequency point transmitting data according to the status of the cable lines relay data to choose and improve the utilization of the system.
        With convenient installation. Users need only access cable TV signal to the F seat of slave and connect RJ45 port and data slave device to complete the installation. Technical Specifications
