Zigbee: new topic. You know me and my curiosity about new technologies. I like to watch the new technology as it tries to establish its own tipping point and become ubiquitous. Zigbee seems like it is at the beginning of this move. You will read about zigbee in Current Buzz from now on. Wi-Fi, which I followed from its beginning is just about ubiquitous, so it is of less interest to me now. When whole cities (Philly, for example) are getting wired, and every coffeeshop is a wi-fi zone, even journalists who are often the worst type of close-minded techno-phobes probably are using Wi-fi, so I am going to write about it less as I shift my interest to Zigbee. Just in case you are thinking, who would want to use zigbee, I note my husband would like to be able to sit at my computer and monitor the efficiency of oury heating system and set the thermostat setback to its most efficient setting. I think it would be fine to use zigbee to send a shopping list to my phone's "to-do" list from my refrig, based on what products are running low. So much for the news from geek central. What Is ZigBee?
