Antenna o The antenna couples energy between the air and the AIR module For applications where installations are done by an end user non professional an omni directional antenna pattern is desired such that the application will work equally well in any direction Similarly for peer to peer or point to multipoint applications an omni directional pattern is desired such that all nodes have a fair chance of communicating The A2500R24A module has an integral antenna that is near omni directional whereas the A2500R24C has approved antenna options ranging from near omni directional to shaped front back patterns useful for inline professional installations Note that the end radiation pattern depends not only on the antenna but also on the ground plane enclosure and installation environment e Filtering o Filtering removes spurious signals to comply with regulatory intentional radiator requirements e Matching o Matching provides the correct loading of the transmit amplifier to achieve the highest output power as well as the correct loading for the receive LNA to achieve the best sensitivity e Physical o physical layer provides conversions between data symbol and RF signal MAC o The MAC layer is part of the Logical Link Layer and provides frame handling addressing and medium access services Microcontroller Interface o microcontroller interface exposes registers and commands for the physical and MAC layers to a micro
