Jul 12, 2010 07/12/10 Project: IEEE P802.15 Working Group for Wireless Specialty Networks (WSN) Submission Title: 6 GHz NPRM and EC RLAN Discussion Date Submitted: January 2018 Source: Tim Harrington, Pro-ID Consulting Contact: Tim@UWBAlliance.org Voice: +1 408 309 2503, E-Mail: Tim@UWBAlliance.org Re: Enhanced Impulse Radio Technical Group Abstract: Discussion of options to deal with proposal of 6 GHz RLAN Purpose: Discuss options to counter effort by RLAN to move into 6 GHz with high power RLAN. Also to discuss mitigation options to propose to the FCC, ECC, and RLAN community. Notice: This document has been prepared to assist the IEEE P802.15.

How bad is the problem? Applications Affected? 1,2,3 Consumer Apps Key fob Smartphone “Follow me” apps POS transactions Industrial Apps Tool tracking Automated assembly Sports Tracking

Possibilities Should 1% duty cycle be written into the rules RLAN defends using Monte Carlo simulation for 1% duty cycle Less Power for RLAN centered at 6.55 GHz More Power for Part 15.250 and UWB Frequency Options: Extend Band for Part 15.250 to higher band – but military above 7.250 No Mobile Hot spots Or perhaps only low power hotspots? Mobile devices only use (Mobile or Fixed) must turn off 6 GHz on command Will allow for a device to detect and control rogue devices Could be used to protect vehicles Mobile devices only use 6 GHz on command from AP Other Options?
