XBee S2D ZigBee how many nodes?

Hello,

we bought the XBee S2D-SMT ZigBee Kit to build a large sensor network. Because of the large number of devices in the network i have some questions:

  • how many devices can be discovered by repeaters and the coordinator module? (i think about a number like 500 modules? is it possible?)

We don’t know which wireless technology we want to use for our end product, but it should be possible to run these modules with a single battery for years and achieve a good range in large buildings.

Thanks for your help!
