Introduction
The LKAV-3621 is a mini size OFDM IP radio works at 800MHz, 1.4GHz
and 2.4GHz bands, with frequency hopping technology (FHSS) to
ensure good stability even in rapid movement condition. It supports
data rate up to 30Mbps and transmission range up to 10-20km
air-to-ground, is ideally suit for long range and high data stream
wireless transmission applications, such as
Surveillance/UAV/USV/Robotics.
