TPC is not supported, so 5250-5350 should be 20dBm (100mW) as description of
ESTI EN 301 893. Since we can extend adjacent channels, add AUTO-BW attribute
to them.

By source, 1000mW is only for outdoor application. Should be 500mW.
Then, it also satisfies the limit 27 dBm defined by ESTI EN 301 893 without TPC.

I think the range should be reference to ETSI EN 302 502, which EIRP level to a
level not exceeding 24 dBm for ChS = 20 MHz and 21 dBm for ChS = 10 MHz.
Then, this rule should be 24 dBm.

However the source points to standard EN 301 893 (wrongly?).
