The chip itself may only be able to put out 18dBm at the lowest transmit rate and significantly less (12-14dBm) at the highest transmit rate. The manufacturer may then opt to add extra output amplifiers :) (Also, I'm doing the FreeBSD port to the AR9340 now, in my spare time. Watch this space!) -adrian On 6 October 2013 01:53, Sven Hazejager wrote: > Does anyone know enough about the various Atheros devices to tell me the > differences between various radios, output power, sensitivity and expected > range? > > For various reasons, I am thinking of replacing my present FreeBSD ALIX > router by a COTS OpenWRT router such as the TP-Link WDR3600. > > Current hardware is a WNC DNMA-83 AR9160 chipset and I'm only using 2.4GHz. > > The TP-Link has a AR9340 for 2.4GHz and a AR9582 for 5GHz.
