AeroComm AC4790 900MHz RF Peer-to-peer TransceiverAeroComm AC4790 900MHz RF Peer-to-peer Transceiver

  • True peer-to-peer protocol.
  • Small form factor: 1.65 x 1.9 inches.
  • API commands to control packet routing.
  • Software-controlled sensitivity.
  • Remote radio discovery.
  • Variable output power: 5mW to 1000mW.

High-performance AC4790 transceivers utilize AeroComm's "masterless" protocol, allowing each transceiver to communicate with any other in-range transceiver for true peer-to-peer operation.

Using field-proven 900MHz FHSS technology that requires no additional site licensing, AC4790s resist interference, enable co-located system operation, increase output power and maintain data integrity.

AC4790's protocol features a dynamic addressing scheme, which simplifies node-to-node communication. The transceiver identifies the most efficient transmission path, so OEMs can design routing sequences that optimize the RF network. This makes AC4790s ideal for a wide range of industrial applications that must rely on smooth, constant data flow.
