Dear Bob,

The Radio Regulatory Technical Advisory Group (802.18) is the liaison between the wireless Working Groups of IEEE 802 and national and international Regulatory agencies. IEEE 802 wireless standards are part of a network infrastructure that utilize ‘best effort’ physical layer transport, and may not provide real-time service.   Additionally, some of these systems operate on unlicensed frequencies and are not afforded any protection from interference. We believe there are applications where hospitals may benefit from the use of IEEE 802 standards.  However these IEEE 802.11 and IEEE 802.15 devices were never intended or designed for life critical applications.

Sincerely,

Michael Lynch
Chair, IEEE 802.18 Radio Regulatory Technical Advisory Group
