Quoting from the PDF:
2Wire's unique triple wireless antenna design extends wireless reach and boosts performance compared to typical 802.11 wireless designs which have only two-antenna. HomePortal has a third antenna used only for transmitting packets. This means 2Wire's wireless gateways avoid the power loss associated with switching the antenna use back and forth, from transmit to receive. Antenna placement is optimized with a dedicated set of receive-only antennas resulting in greater access point sensitivity and increased wireless throughput and range. And increased bandwidth throughout the home is critical for high-bandwidth, value added services such as digital media.
Feh. It is likely that the loss of reciprocity inherent in this "solution" actually costs them 3dB of link margin. (Perhaps more if the unit is badly placed.) All in the name of avoiding a t/r switch.
Now, if this is FCCID: PGR2W1000W (and I'll assume that most here know how to look that up), then the
stated RF power output (in the RF exposure info document) is 19.5dBm, or 89mW. They claim a 3dBi antenna, for
22.5dBm, or 178mW EIRP.
If its FCCID: PGR2WHPLHW, (which is, btw, an older certification), then they claim (and tested) 26.02dBm of tx power into a 2dBi antenna, for 633.9mW EIRP. This is the 400mW unit.
