1.4. Theory of Operation
The A2541R24A and A2541R24C modules operate in the global 2.4 GHz ISM/SRD frequency
band. They can be used to implement a variety of networks, including point to point, point to
multi-point, peer to peer and mesh networks.
Figure 1 and Figure 2 show the functionality of A2541R24A and A2541R24C, respectively. Both
modules operate in a similar manner except the antenna part where A2541R24A communicates
through a built-in antenna, and A2541R24C communicates through an external antenna
attached to a U.FL antenna port.
