Background For Motions• Japan’s Ministry of Public Management, Home Affairs, Posts and

Telecommunications (MPHPT)– http://www.soumu.go.jp/english/index.html

• Recent activity– Held Public Enquiry about additional License Exempt spectrum in 4.9GHz

band:• 5MHz or 10MHz channels in 4.900-4.950GHz• 20MHz channels centered at 4.920, 4.940, 4.960 and 4.980 GHz

– And in low 5GHz (5.03-5.091GHz) band:• 5MHz or 10MHz channels in 5.030-5.060GHz• 20MHz channels centered at 5.040, 5.060 and 5.080GHz

– Considering experimental operation in low 5GHz this year– Issues for 802.11:

• 2.5MHz channelization authorised for 5MHz and 10MHz channels• IBSS prohibited in these bands• APs must respect 4msec rules on transmission and detecting other APs

Summary of the changes

• Wireless LANs have been regulated in 2.4GHz, 22/26/38GHz and 5.2GHz (for in-door use only). It is strongly expected for 5GHz band wireless access systems to be available for out-door usages. The object is to change related regulations to support the out-door 5GHz wireless access in 4900-5000 and 5030-5091 MHz.

Summary• Small changes to 802.11, .11a and .11d to meet Japan’s

proposed regulatory requirements for low-band 4.9-5GHz operation

• PAR/5 Criterion preparation does not appear to warrant formation of a Study Group, but should developed to be submitted to the 802 exec before November 802 Plenary.

The WG Motion

Move to empower WNG to draft a PAR and Five Criteria to extend 802.11, 802.11a and 802.11d to the Japanese

4.9GHz-5GHz bands, and after a Working Group confirming vote in the September 802.11 interim

meeting, empower the Working Group to forward them for approval at the November 2002 IEEE 802 Plenary
