Licensed Microwave Wireless Backhaul (White Paper)
Licensed microwave wireless backhaul is also known as fixed wireless backhaul. A licensed microwave link is a point to point wireless bridge or a point to multipoint wireless bridge used for wireless Ethernet backhaul. Microwave backhaul is becoming more popular for wireless Ethernet bridge applications as a result of noise interference in unlicensed wireless spectrum ( U-NII Band ).
The term "Microwave" is a broad term that covers the UHF ( Ultra High Frequency with frequencies between 300MHz and 3GHz ) to the EHF ( Extremely High Frequency with frequencies between 30GHz to 300GHz ) . Licensed microwave links operate in the SHF ( Super High Frequency with frequencies between 3GHz to 30GHz ) and the EHF bands. Typical licensed microwave link frequencies used for wireless backhaul operate within 3.65GHz WiMax ( as a point to multipoint wireless backhaul) , 4.9GHz public Safety, 6GHz, 11GHz, 18GHz, 23GHz bands and the 80GHz millimeter wave E-band.
