Summary This document address to resolve the following comments for sponsor ballot regarding to Japanese 920MHz band. Following CIDs are addressed; 67, 68, 69, 75, 76, 77, 78

Background on Reallocation of Frequency Band for Smart Utility Network (SUN) in Japan Currently 950 MHz band has been assigned for SUN and 802.15.4g draft has been edited on the frequency band. 950MHz band will be reallocated to new mobile phone services such as LTE: Long Term Evolution in order to harmonize with other countries / regions. Instead, the frequency band for sensor networks including SUN, smart meters, etc will be moved from 950MHz band to 920MHz band (915MHz - 930MHz).
