Wi-Fi for sensor nets?

That's the case GainSpan made over lunch to me the other day. Zigbee, the startup claims, lacks links to network management software such as HP's OpenView and IBM's Tivoli. Existing Zigbee nodes from the likes of Ember, Dust, Crossbow and others lack the interoperable gateways prevalent in the 802.11 world. And some apps need the 1-2 Mbits/s GainSpan's 11b/g Wi-Fi chip can crank out when needed—and still deliver the 3-5 year battery life required of a sensor node.

I hope to dig into this a bit further next week. If you are working in sensor nets with Zigbee, Wi-Fi or some other net, I'd like to hear your thoughts. Drop a comment or email me at rbmerrit@cmp.com
