The AMB2220 is a compact high performance 2.4 GHz (half-duplex) long range wireless module. It can provide an output power of up to 10 dBm allowing a transmission range from 500 meters (line of sight) to 5 km (with an external antenna) based on the type of transmission. The module has an integrated microprocessor that controls data communication, handling packet and checksum generation, addressing, monitoring of channel access and re-transmission of lost packets. The host system does not have to perform any radio-specific tasks. The embedded software protocol stack supports star and peer-to-peer networks.
The module can be configured in many ways and supports data transfer with fast channel and address switching. An opportunity to assess the quality of the radio link is also provided by using the measured field strength (RSSI value). The graphical user interface of the freely available Windows application “AMBER-ACC” makes it easy to set operating parameters.
It is ideal for long distance applications with low data rates. The AMB2220 measures 17 x 30.8 x 4 mm.
