asterisk users - Aug 2004 - WiFi phone radiation regulation?

All,

I just had the fortune to take one of the new Senao Wifi SIP phones for 
a short test drive. First look - it's a nice, compact phone. Weighs 
around 87g and roughly the size of a Nokia 6210. More on the those 
later. The thing that struck me was the RF power, it's rated at 100mw 
(20dBm). That's 10 times more than any of the other brands out on the 
market  Cisco, WiSIP, Zyxel are all rated at 10mW.

I'm not really sure if I want to stick something with that power to my 
ear. Assuming a reasonable antenna gain of 2.2dBi, we're talking about 
22.2dBm - that's nearly 200mW of power radiating out of the phone. At 
2.4GHz, it has higher penetration power than cells phones.

My question:
Does anyone know if cell phone SAR rules apply to WiFi phones as well? 
Over here in Singapore, there seems to be a loophole. As long as your 
equipment is in 2.4GHz, approval is not required if Tx power is <200mW.

I've had an e-mail into pulver for a few days on getting access to the
firmware w/o a response. Anyone have the most recent wisip firmware they
wouldn't mind posting or e-mailing me?

Thanks,
Bill

I have one of those SMC High Power W-LAN cards for special war driving 
applications :-) It is rated at 200mW and is sold over the counter. Ok, 
I usually don't put the card on my ear...
