Wireless Bridge

Wireless bridge

Wireless bridge is for the use of wireless (microwave) long distances of data transmission between point-to-point nets interconnected design. Come up from the function, it can understand wireless bridge for connecting two or more independent network segment, these independent network segment is usually located in different buildings, hundreds of meters to dozens of miles apart. So it can be widely used in different between buildings of interconnected. Meanwhile, according to the agreement is different, wireless bridge can divide again 2.4 GHz frequency band 802.11 b or 802.11 G and adopting the 5.8 GHz frequency band 802.11 a wireless Bridges. There are three kinds of wireless bridge work style, point-to-point, point-to-multipoint, relay connection. Especially suitable for long-distance communication in the city. It has two kinds of access, IP interface access, IP + E1 double interface access.

In no tall (the mountains or building) obstacles, under the condition of a pair of speed networking and field operations temporary networking. Its action distance depends on environment and antenna, presently 7km point-to-point microwave interconnection. A pair of directional antenna can realize 27dbi 10km point-to-point microwave interconnection. 12dbi of directional antenna can realize 2km point-to-point microwave interconnection, A pair of only realizes the link layer function of wireless bridge is transparent Bridges, and having the routing and other network layer function, in the network 24dbi of directional antenna can realize heterogenous network interconnection real layer of device called the wireless router, but also can be used as the third Bridges use.

Wireless bridge is usually for outdoor, mainly used for connecting two network, the use of wireless bridge could not only using a, it is necessary to two above, and AP can be used alone. Wireless bridge big power, long distance transmission (maximum will reach about 50km), strong anti-jamming capability, etc, do not bring a parabolic antenna, general equipped with long antennas realize point-to-point connections.

On market now has appeared 802.11 wireless bridge n, transmission rate can reach 300Mbps above. But by various factors, the actual rate is far below businessman flaunt numerical. But the rate of relative to 11g did improve a lot, it also allows us to require high bandwidth, high transmission rate become possible. Along with the development of technology, believe there is more new products with the emergence of new technology derived.
