doc.: IEEE 802.11-02/480r0 Submission July 2002 Peter Ecclesine, Cisco Systems, et alSlide 6 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. http://www.soumu.go.jp/s-news/2002/020611_3.html#01
