6. UWB in JAPAN Near field high speed communication only.
Power level is limited lower than 41.3dBm≒74nW/MHz, bandwidth should be kept GHz or GHz in JAPAN. The minimum data rate is 50Mbps.
From 2010 low band will be narrowed to 4.2GHz to 4.8GHz and DAA will be mandate.
Tags must be response from AC powered interrogator. One way beacon is prohibited.
