I'm not sure about Zigbee, but the useful range of Bluetooth is very
short. There are claims of over 30 meters, but as far as I can tell
that must be under laboratory conditions, e.g. in a faraday cage.
In the real world, more than about 3 meters line of sight works poorly,
as does non-line-of-sight at any distance.
Get an old satellite dish, remove the LNB, cut a piece of wood to fit
with a slot that will take a bluetooth USB dongle and then point it at
someone a mile away. You should be able to associate to their phone.
