Product Description

10km UAV Data Link Video & Data Frequency Hopping Low Latency


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.



■TDD-OFDM modulation

■Supports 3 bands (800HMz/1.4GHz/2.4GHz)

■Supports FHSS inside each band

■1.4/3/5/10/20MHz five channel bandwidths

■Max 30Mbps@20MHz throughput

■Supports one-to-one, one-to-many and many-to-one transmission

■Supports serial data and video at the same time

■Up to 10-20km LOS (air-to-ground)

■WebUI for management

■AES128 encryption (user-defined)

■Uplink and downlink stream control

■Compact size and light weight

■Rugged aluminum alloy housing
