EOA-100 Ethernet-over-Air Adaptor

             


Ref. Price for a link (2pcs): US$399/ $499


EOA-100 Ethernet-over-Air adaptor is designed with the IT9560 COFDM transceiver chips. EOA can be used to extend Ethernet wirelessly.
The nature of robust COFDM technology enables versatile long range wireless applications, like UAV’s,
The EOA is built in with 900MHz band 100mW power amplifier, conducted RF power output @+20dBm. It’s optional (and easy) to disable the on-board power amplifier, and redirect the RF to an external power amplifier via the two by-pass SMA connectors.
EoA supports both 1-to-1 (point to point) and many-to-many communication modes.
Besides transparent Ethernet wireless link, the board can be configured as a transparent UART (RS232/RS485) link. One RS-232 and one RS-485 are supported simultaneously at up to 921K bps data rate.

System Features
