Frenchy... are you looking for the Zigbee protocols, or just 802.15.4 simple messages where you don't even have to have a PAN coordinator (it's an option). Zigbee is all about mesh routing at the network layer. XBee series 1 are non-Zigbee; series 2 are zigbee-only.
Digimesh is a good alternative to Zigbee - works better.
Most simple RF comms in hobby-land can be done with series 1 and no zigbee- far simpler. And series 1 has the built-in firmware to do I/O and data acquistion, recurring, without an attached microprocessor at the sensor end.
there is no equivalent to the XBee as above, where you have that firmware free, already written.
The XBee Pro modules have 60mW vs. 2mW for the non-Pro. But a gain antenna on one or both ends of the link can offset. Battery life is limited by the receiver rather than transmitter - except when you use a very chatty protocol like Zigbee.
Atmel's 802.15.4 is the product previously known as Meshnetics. Not well documented/supported, IMO. Perhaps OK for high volume OEMs.
Anaren has modules, using TI's CC2530, but they are hardware only. you're DIY for all firmware, and serial port/SPI interface is a problem for small quantities.
This is in the context of 2.4GHz. In the US, there are a few 802.15.4 and more yet proprietary modules for 902-928 unlicensed. In the EU, that has to be 868MHz.
