ETL-210A

COFDM Ethernet-over-Air Adaptor

The ETL-210A is a bidirectional COFDM Ethernet-over-Air transceiver for long-range UAV and USV links, field-verified at distances beyond 500 km with up to 26.8 Mbps in each direction (64QAM) over independent uplink and downlink channels. The base unit tunes from 100 to 2500 MHz in 1 kHz steps, with custom bands available from 100 MHz to 6 GHz, and secures traffic with AES-128/AES-256 encryption. Its COFDM ASIC, firmware and boards are designed and manufactured in Taiwan.
