The IEEE 802.16 designed to operate in the 10-66 GHz spectrum and it specifies the PHYsical layer (PHY) and Medium Access Control layer (MAC) of the air interface BWA systems. At 10-66 GHz range, transmission requires Line-Of-Sight (LOS). IEEE 802.16 is working group number 16 of IEEE 802, specializing in point-to-multipoint broadband wireless access. The IEEE 802.16 Working Group created a new standard, commonly known as WiMAX, for broadband wireless access at high speed and low cost, which is easy to deploy, and which provides a scalable solution for extension of a fiber-optic backbone.
