From one of my contacts today in the medical marketplace, the question came up, should we use 802.11b/g, or a? Bottom, line is the cost is built into the silicon. 802.11b, is legacy, and g, has displaced, while a offers other than 2.4GHz. 802.11a/b/g radios are defacto. In the presence of b, g, will fallback, this will allow connectivity in legacy 802.11b clients are present. In light of the need to conserve power and maximize security and 802.11e, it felt that medical device companies just may desire to look to Atheros. Oh, yes, regarding 802.11n, with MIMO requirements, way too power intense. Plus, the medical device marketplace does not any of this bandwidth.
