Long Range Wireless Bridges for Remote Video Backhaul
Video backhaul encompasses the transport of video from cameras in remote locations to a central location for viewing or storage more. Sometimes this might require multiplexing data from different cameras to a central station before it is transported from the central station to yet another location. RfWeL offers various solutions to enable this long-range wireless non-internet based video backhaul. Recommended method is to use IP-enabled cameras and the all-pervasive IP networking for backhaul. We also offer non-IP video/audio transmission solutions as well as systems to convert legacy cameras systems to IP allowing us to take advantage of a rich selection of IP long-range bridging solutions. Axis is our IP camera provider more

Ethernet Bridging of Wireless Video
 

The four main frequency bands used for these applications are 900MHz, 2.4GHz, 4.9GHz and 5.8GHz. Each has its own benefits and shortcomings so we work closely with you to understand your requirements and other constraints. We don't encourage 2.4GHz ISM due to it's high potential of interference. 4.9 GHz is licensed for Public Safety use. Contact us if interested in 4.9GHz solutions.

900MHz Non-Line-of-Sight Wireless Video:
900MHz products provide an ultra-long-range non-line-of-sight (NLOS) outdoor wireless broadband backhaul. Utilizing the 900MHz spectrum for wireless transmission, IP based cameras are able to be deployed in areas that may be obstructed by trees, buildings, or any other obstacles. 900MHz signal can pass through 3-4 leafy trees with little to no data loss in throughput. Our 900 MHz solutions allows for a maximum of 1.5Mbps raw data rate - this equates to an IP camera running approximately at 8-12 fps @ 320x240 resolution or 4-6 fps @ 640x480 resolution.
A few other benefits of 900MHz (Avalan Wireless is our 900MHz hardware provider more
