WiFiber
Description: 

WiFiber is short for Wireless Fiber that can provide the backhaul communications. Gigabeam [1] has developed WiFiber G1.25-- a point-to-point wireless technology -- which is neither optical nor based on WiFi/WiMAX standards, yet delivers a data rate of up to 1 Gigabit-per-second (Gbps) through use of Gigabit Ethernet (802.3z) and other standard protocols [2]. WiFiber exploits different part of spectrum near visible light, at terahertz frequencies and transmits in the 71-76GHz, and 81-86GHz radio spectrum bands [3] where there is less traffic hence less time can be spent in routing the data and more time delivering it. WiFiber operation requires line-of-sight and can beam up to 10 miles between between two points. The author in [4] indicated that the communication range is 3 miles for 99.9% availability.

Features include [3]:
• Full Duplex sustained GigE throughput (Layer 1, low latency, unlimited packet sizes on both IPv4 and IPv6)
• High reliability design with dual input/internally redundant power supplies
• Single field replicable unit with rapid slip-fi t antenna mount for low mean time to repair
• Lightweight, small footprint, all outdoor design for ease of installation and commissioning
• Local and remote system management via SNMPV2c
• Automatic Transmit Power Control (ATPC)
• Forward Error Correction
• Security Suite: Radius, SSH, Denial of Service Enhancements

Applications: 

WiFiber can serve as a wireless backhaul for transmission and distribution communication systems, and supporting AMI systems applications. It can also be used to support WiFi applications for substation or distribution automation. WiFiber can be deployed quickly (in a day) and is a much more cost-effective solution compared to its terrestrial fiber counterpart.
