Wireless Point to Point Bridges

JEFA Tech offers a selction of Point to point wireless bridges are available in 3 unlicensed frequency bands - 2.4GHz, 5GHz, and 900Mhz. Each band has its advantages and disadvantages.

2.4 GHz (2400MHz) is the most widely used frequency band for WiFi and unlicensed point to point network links. 2.4GHz requires line of sight for best performance, however it is somewhat tolerant of sparse trees. A drawback of 2.4GHz equipment is due to the popularity of this band, it is crowded in populated areas and likely to have interference which can affect your data rates. In a rural environment, this is not as great of a concern. If you are operating a large outdoor WiFi network, it is best to create your backhaul bridge network on a band other than 2.4GHz if possible.
5 GHz (5000MHz) is a much less crowded band and is the preferred band for point to point, line of sight links. It will not interfere with 2.4GHz WiFi networks so it is a perfect choice for an outdoor backhaul to wirelessly link remote access points. It is also ideal for point to point building links where there is a clear line of sight between the buildings. The drawback is 5GHz is not tolerant of line of sight obstructions. You must have a clear path between your bridges. Use the rule of thumb "if you can see it, you can link it".
900 MHz is the lowest frequency band available for wireless network links. Due to the relatively low frequency, 900MHz is very tolerant of line of sight issues and will go through even thick stands of trees in many cases. However, the drawback of 900MHz is a low data rate. Use 900MHz if you are unable to get your antennas above the trees, but be aware you may only get a rate of 1 - 2MBps on a point to point link.
