[Olpc-open] radio transmit power and health

[John Kintree]

Information for the Marvell chipset in the hardware section of the OLPC wiki says, "Tx power at pin = +22dBm at 11b, +16dBm at 11g."  Can someone translate what +22dBm means in milliwatts, or in mw/cm2.  The FCC limit for power density is 1 mw/cm2.  How far below the limit is the Marvell chipset?
Thanks,
John Kintree

Concern is sometimes raised about the possible harmful effects of exposing children to microwave radiation.  It's my understanding that consumer WiFi products in general have a lower transmit power (often 30 milliwatts) than cell phones (as much as 1 watt), and therefore have fewer potential risks, especially since laptops are not held against the user's head the way cell phones are.  Some of the concerns might be reduced if we could tell people what the transmit power of the radio in the OLPC computer is.
