What is a wireless bridge?

As the name suggests is a wireless bridge wireless network bridging, which uses wireless transmission achieved between two or more networks put up a bridge of communication; wireless bridge into a bridge circuit type and data type bridge from the communication mechanism.

Concept
Circuit-type bridge wireless transmission mechanism using PDH / SDH microwave transmission principle, the principle of realization interface protocol using bridging, with data rates steady, small transmission delay characteristics, the demand for multimedia converged network solutions, suitable as 3G/4G interconnection of mobile communication base stations;
Data type bridge using IP transport mechanism, interface protocol using bridging principle to achieve, with flexible networking, low cost characteristics, suitable for low-level network data transmission and image transmission in monitoring class, widely used in various data based on pure IP architecture network solutions.
Feature
In addition to the above-mentioned wireless bridge cable bridge beyond the basic features, free wireless bridge 2.4G or 5.8G in-band wireless applications for licenses, and thus easier to deploy than other wired network devices.

Transmission of data
According to the data transfer rate of the bridge type using different criteria, as follows:
Wireless bridge transmission standard often used 802.11b or 802.11g, 802.11a and 802.11n standard, 802.11b standard data rate is 11Mbps, while maintaining sufficient bandwidth data transmission premise, 802.11b usually able to provide the actual 4Mbps to 6Mbps data rate, and 802.11g, 802.11a standard for wireless bridges have bandwidth to 54Mbps, the actual data rates of up to about 5 times the 802.11b, the current through the turb and Super mode transmission bandwidth of up to 108Mbps; 802.11n can usually provide transfer rates of 150Mbps to 600Mbps.
Bridge circuit type modulation transfer rate and bandwidth according to different decisions, PTP C400 up to 64Mbps, PTP C500 up to 90MBPS, PTP C600 up to 150Mbps; You can configure the carrier-class E1, E3, STM-1 interfaces.
