Low power wlan devices

Who makes WLAN chips that go into cell-phone/smart-phone? A search leads to some information:

1) Atheros AR6002 (Oct 2007)
- 70 percent less power than competitive solutions on the market in active mode while downloading content
* 100 hours to deplete a standard 3.7V, 800mAh phone battery in continual VoIP mode
* 200 gigabytes of data can be downloaded before depleting the same battery
- Near-Zero Power in Standby (6 µW)

2) Broadcom BCM4326 (Oct 2006)
- single-chip 802.11Wi-Fi transceivers and radios with an innovative software architecture that drastically reduces the Wi-Fi subsystem's total power consumption
- exceptional power performance that enables a 54Mbps full-rate active receive power consumption of less than 270 mW
- system battery life enhanced through combination of complete on-chip driver control and other sophisticated software capabilities

Comments:
As the deployment of WiFi increases, it will be adopted in more mobile devices to enable better coverage and also different business models and applications. As a result, I would think
a) the market for wifi chips will grow (and maybe follow the trend of cellphone chips)
b) the winner will likely be the low-energy candidate (assuming all other things are equal)
