Background
The Ministry of Internal Affairs and Communications is developing regulations for the new radio allocation of 950 MHz band in Japan.
The first regulation for the passive tag systems had already been issued.
Now Japanese committee is working on the second regulation for the LR-WPAN and active tag systems. Expected completion in Q4/2006.

5. Requirements for new regulation
July 2006
Requirements for new regulation
The new regulation should co-exist with the existing passive tag systems.
The regulation for the passive tags will not be changed for the new systems.
Special requirements from the passive tag systems are
Narrow band width, and
Channel alignment with the passive tags.
