The goal of this group is to publish standards, recommended practices, or guides that have broad market applicability and deal effectively with the issues of coexistence and interoperability with other wired and wireless networking solutions 802.16 Broadband The IEEE 802.16 Working Group on Broadband http://grouper.ieee.org/groups/ Wireless Access Wireless Access Standards develops standards and 802/16/ recommended practices to support the development and deployment of broadband Wireless Metropolitan Area Networks. 802.17 Resilient Packet The IEEE 802.17 Resilient Packet Ring Working Group http://grouper.ieee.org/groups/ develops standards to support the development and 802/17/ deployment of Resilient Packet Ring networks in Local, Metropolitan, and Wide Area Networks for resilient and efficient transfer of data packets at rates scalable to many gigabits per second. These standards build upon existing Physical Layer specifications, and will develop new physical layers where appropriate. 802.18 Radio Regulatory- The mandate of this Working Group monitoring of, and http://grouper.ieee.org/groups/ Technical Advisory Group active participation in, ongoing radio regulatory 802/18/ activities, at both the national and internationa
