2.1 Selecting an ADAM-2000 Module
2.1.1 Selecting a Communication Module
Communication modules are fundamental when needing to perform data acquisition
and control Wireless Sensor Networks systems. There are two types of communica-
tions modules: the coordinator and the router.
A coordinator is essential to associate an Wireless Personal Area Network (WPAN)
and as a data collector of the WPAN. Only one coordinator available in a specified
WPAN of a specified RF channel. A coordinator also acts as a gateway to translate
data packets between two different networks.
The router is optional in a PAN. The major function of a router is to repeat the wire-
less signal to improve the LQI. With routers, a PAN can be easily extended. More
routers in a PAN means larger coverage and capacity of the network.
