Looking at the Japanese section of the website it seems that the beacon will be 15w on 5.8 Ghz (I may be wrong about this because hese are the nly non-Japanese characters).
I wonder what the qrm might be from this system on 5.9 GHz? This is an experimental road-tolling system outside Denver Colorado.

This will rapidly go off-topic, but...
I don't think it matters much at all (5.8 to 5.9 is a significant frequency change at 5 GHz), but that system will generally be decommissioned soon.
The E-470 toll road will be switching to using nothing but video cameras to photograph license plates for their billing in July of 2009.
The RF system won't be in use after that, AFAIK.
