* To determine your range, perform a range test under your operating conditions
The frequency used is the 900 MHz band, using 64 software selectable channels. Channels are spaced 400 kHz
apart. The transmission rate is 10 kbps. There are different versions of the XBee 900HP: USA & Canada, Brazil and
Australia.
The different versions differ mainly in the available channels, which are hard-coded in the XBee. Be aware that it is
not possible to change from one version to other with just a firmware change.
According to the country where
the user is located, a different version must be chosen.
The classic topology for this type of network is a star topology, as the nodes can establish point-to-point connections
with brother nodes through the use of parameters such as the MAC address or that of the network.
