[wireless-regdb] Review of EN 301 893 1.5.1 and 1.6.1 changes

[Michael Green]

Luckily, the "harmonized standard" is by law, one and only one for DFS conformance across all European Community countries. 

There are no differences in pulse patterns, non occupancy, channel close time, etc etc. across EU countries.  I have not gotten any indication from anywhere that there will be deviation on a country by country basis in Europe affecting DFS rules.

BTW, as of June 30, 2010, EN301 893 V1.5.1 became mandatory.  All devices placed on the EC market must meet those latest pulse patterns per V1.5.1.

tks,

you think I'm mocking you, maybe I am :P

I just fear that will not allow us to keep manoeuvring effectively in
the future, because then we need to change all the implementations,
potentially old ones, rather than just updating the database.

I wasn't so much thinking of the pulse patterns though as the other
timings like the airtime allowed to use before moving onto a new
channel.
