The ZKManet2421UM is a miniature OFDM IP radio that operates in the 800MHz, 1.4GHz and 2.4GHz frequency bands with frequency hopping spread spectrum (FHSS) to ensure good stability even in fast-moving situations. It supports data rates up to 30Mbps and air-to-ground range up to 5-20km, which is ideal for long range and high data stream wireless transmission applications such as surveillance/UAV/USV/robotics etc.
* Up to 5-20km LOS (air-to-ground)
* AES128 encryption (user-defined)
* TDD-OFDM modulation
* Compact size and light weight
* Rugged aluminum alloy housing
* Max 30Mbps@20MHz throughput
* IP data transparent transmission
* 1.4/3/5/10/20MHz five channel bandwidths
* Supports one-to-one and one-to-many transmission
* Supports FHSS inside each band and across bands
* Supports 800MHz, 1.4GHz, 2.4GHz frequency hopping transmission
a. ANT2 Port - Auxiliary antenna, works as auxiliary receiving, NO transmitting.
b. ANT1 Port – Main antenna, work mode is TDD transmitting/receiving.
