Guide to Wireless Bridging
What is a Wireless Bridge?
A wireless bridge is used to provide Ethernet network connectivity where the installation of cabling is impractical, most commonly to provide network connectivity over large distances.
The equipment consists of a radio and antenna at each end, taking an Ethernet cable input at the beginning of the link and an Ethernet cable output at the other end of the link.
Put simply the unit transforms the packet data from Ethernet cable into a wireless radio signal, and then back to Ethernet cable - the transformation affects only the L1 transmission, ensuring the link is transparent at L2.
How far can I bridge?
As far as you need. Naturally the longer the distance the more expensive and complicated the required equipment becomes.
Irrespective of frequency band, the limiting factor on a wireless link is SINR - Signal to Interference Noise Ratio (or S/I+N).
SINR is reduced by a reduction in signal strength due to distance or the presence of obstructions, an increase in noise from thermal/environmental conditions, or interference from hostile transmitters.
Signal strength can be increased while simultaneously reducing interference and noise by the use of high grade antennas. This process can be augmented by using larger and larger antennas, appropriate to the distance and radio conditions imposed by the required link.
