mmW DEV is required to support “802.15.3-MAC based data transmission mode” and “IF-mmW Non-regenerative repeater mode”
Maximum available band for a mmW DEV (2.5 GHz in Japan) is divided into 5 mode-selectable sub-band (500 MHz)
Which mode to be used is selectable for every sub-band
Example of requirement policy under Japanese radio regulation

Millimeter-Wave Self-heterodyne Technique suitable for non-regenerative repeater
Low-cost mmW LO is available at Tx. and no LO is required at Rx. ---> Drastic cost reduction of mmW RF front-end
Frequency offset and phase noise are completely cancelled out ---> Extremely frequency stable transmission
(Maybe non-regenerative channel quite sensitive to frequency offset is included.)

Summary
IF-mmW non-regenerative repeater application for broadcast video is important for 15.3c WPAN
Proposed to introduce “Non-regenerative repeater mode” as well as “802.15.3-MAC based data transmission mode” into 15.3c PHY
Which mode to be used is selectable for every sub-band and example frequency allocation plan was shown under Japanese regulation
Low-cost mmW-RF front-end technique based on Self-heterodyne detection is introduced again
