title: Data loss due to simultaneous transmission in ZigBee
body: <p>I'm designing a multi-agent robotic application, where robots communicate through <a href="http://en.wikipedia.org/wiki/ZigBee" rel="nofollow">ZigBee</a> modules. If two (or more) robots send their data simultaneously (at the same time) will it cause data loss at the receiver?</p>
  
  <p>Consider multiple senders and one receiver (where senders send data simultenously and receiver receives them and perform certain tasks).</p>
