Hi Luis,
Can you pls help write a patch for Indonesia. To be honest, I have not
looked at what’s in your sw now but assume it’s outdated.
Latest rules are:
RD: APL2_World
5GHz:
11a center frequencies: 5745, 5765, 5785, 5805
11n HT20 & HT40: Not allowed in 5GHz
2.4GHz
11bg: 1-13 allowed
11n HT20 & HT40 Allowed in 2.4GHz
5GHz: For power levels, not sure what to put. ATHR sets 23dBm for
uniformity. But the rules state 36dBm is allowable. So lets subtract max
gain ant of 6dBi which yields 30dBm conducted tx power. That should be
reasonable to use in sw. It is highly doubtful any device would pass
Indonesia regulatory tests at that level. So 30dBm is a reasonable upper
limit to put in sw.
2.4GHz: Same power level as currently in sw.

FYI and reattached the documents from TEKNOKRAT INDONESIA.
Summary :
1. Only 20MHz BW is allowed @ 5.8GHz since regulation says so.
2. Both 20MHz and 40MHz are OK since there is no restriction about this
in 2.4GHz regulation.

Dear Sir,
We are very sorry that we are only able to submit you the document in
Indonesian since there is no official english available from the regulator.
However your assumption was right, that since there are no restriction on
modulation for 2.4 GHz in the regulation then both 20 and 40 MHz is
allowable in Indonesia.

Hi,
Thanks for the document. Unfortunately I can’t read Indonesian but I think I
can find there is a mentioned about 5.8GHz only accept 20MHz in last page in
5.8GHz document.
Can you please guide me where I can find the regulation state both 20MHz and
40MHz are accepted in 2.4GHz document? Or both are accepted due to no
mention of restriction of Bandwidth in regulation?Thanks.

Dear Sir,
Please be received 2 documents other than the technical regulation which we
believed you have aware of. These 2 documents are actually the official
directive of utilization of frequency 2.4 GHz and 5.8 GHz from Frequency
Department in the regulator's office. Hopefully this could meet your
expectation and please do not hesitate to contact us should you need more
information.

Hi,
Can you please share any official document from regulator so that we can
justify our change to the modulation requirement @ 2.4GHz and 5GHz in
Indonesia.Thank you.

Dear Sir,
Very sorry that we have overlooked your e-mail. Only HT20 is allowable in
5.725 - 5.825 GHz while both HT40 and HT20 are allowable in 2.4 - 2.4835
GHz. Hopefully this could explains.
