Point-to-Point Wireless Bridge and Point-to-Multipoint Bridging:

What is Point-to-Point? When connecting two points together (Referred to as a Wireless Bridge), the distance, obstructions, and antenna height as well as location must be considered. If the antennas can be mounted indoors and the distance is not far (several hundred feet), the standard dipole or upgraded 7dBi Omni-directional may be used.

An alternative is to use two patch antennas for your Wireless Point-to-Point Bridge Kit. GNS Communications offers complete Wireless Bridges that include everything you need to wirelessly connect your two locations safely and securely.

For longer distances (1/4 mile or more), directional, high-gain antennas must be used. These antennas should be installed as high as possible, and above obstructions such as trees, buildings, and so on. These antennas should be pointed at each other, as much as possible. With a line-of-site configuration, distances of up to 25 miles at both 2.4 GHz and 5 GHz can be reached using 24dBi grid antennas, or Motorola Canopy. Contact us for more info.

With the use of directional antennas, fewer interference possibilities exist and there is less possibility of causing interference to anyone else.

What is Point-to-Multipoint Bridging? In this case (in which a single point is communicating to several remote points), the use of an Omni-directional antenna at the main base station point must be used. The remote sites can use a directional antenna that is directed at the main point antenna.
