scope:

The present document supplements IEEE Standard P802.16-2004 [1], which defines the Data Link Control (DLC) and Physical (PHY) of metropolitan area network systems. The present document provides the supplemental DLC functions required for systems operating in frequencies below 11 GHz to support PMP and optionally Mesh network topologies. The physical characteristics of frequencies below 11 GHz, as well as the characteristics of the Broadband Wireless Access (BWA) market segments for which the present document is designed, result in an environment, where Line Of Sight (LOS) is not necessary, multipath may be severe and the physical medium may be lossy.

The present document does not address the requirements and technical characteristics for conformance testing, nor the requirements for the applicable below 11 GHz PHY Layer. Those are covered in separate documents.
