Do you have a transmit ban on 802.11 channels in 4X too?
We as hams in the Netherlands are no longer allowed to transmit above
2400 MHz except to an amateur satellite.
There is a limit of 100mW EIRP for 2400-2450 mHz for terrestrial use,
with a limit of 100W EIRP to satellites in the 2400-2402 mHz part of the
band. This is from a document on the Ministry of Communicatons website,
dated 1999. It has been unchanged except for the addition of 7.100-7.200 mHz
so they never bothered to update it.
The difference between a 100mW limit and an outright ban in practice is
very little IMHO.
For example, you can turn off encryption and use a WiFi device as a packet
radio, or you can call CQ on your cordless phone. :-(
