802.16
In recent years there has been increasing interest shown in wireless technologies for subscriber access, as an alternative to traditional twisted-pair local loop.
These approaches are generally referred to as wireless local loop (WLL), or fixed-wireless access. To provide a standardized approach to WLL, the IEEE 802 committee set up the 802.16 working group in 1999 to develop broadband wireless standards.
An 802.16 wireless service provides a communications path between a subscriber site and a core network (the network to which 802.16 is providing access). Examples of a core network are the public telephone network and the Internet. IEEE 802.16 standards are concerned with the air interface between a subscriber's transceiver station and a base transceiver station.
Protocols defined specifically for wireless transmission address issues related to the transmission of blocks of data over a network. The standards are organized into a three-layer architecture.
