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
