doc.: IEEE /0647r1 Submission May 2010 Bruce Kraemer, MarvellSlide 2 WP5A liaison proposal LIAISON STATEMENT TO ITU-R WORKING PARTY 5C AND EXTERNAL ORGANIZATIONS ON MULTIPLE GIGABIT WIRELESS SYSTEMS IN FREQUENCIES AROUND 60 GHZITU-R Working Party 5A has begun work on a Multiple Gigabit Wireless Systems in frequencies around 60 GHz, under Question 238-1/5. Two working documents are being developed, which are attached for information and comment (see Attachment 1 and Attachment 2). WP 5A looks forward to further collaboration in this area and would appreciate receiving information on relevant related activities that may be useful for the completion of the working documents. The next meeting of WP 5A will be held on 8-19 November Deadline for contributions: 1 November 2010 at hours UTC.
