title: zigbee hardware in mobile phone
body: <p>Is it required for a mobile phone to have a dedicated Zigbee chip in order to be a Zigbee node (coordinator/router/endnode) ?</p>
  
  <p>If yes, then, I guess there should be a driver module for it as well ?</p>
  
  <p>I don't know about the exact HW structure of mobile phones; in laptop we have a wlan card with its own antenna and driver; how about mobile phone ? there are separate wifi, gps and bluetooth chips with separate driver modules for each, and all sharing the same antenna ?</p>
  
  <p>Thanks</p>
