Equipment technical parameters:

1) Technical advantages

l Long transmission distance: using COFDM modulation, space-time coding, transceiver diversity and other technologies,

The receiving sensitivity can reach -104dBm, and under 2W transmission power, the ground-to-air/space-to-air line-of-sight communication can reach 40km, and the ground-to-ground line-of-sight communication can reach 20 km. It also has better anti-multipath interference and interference under non-line-of-sight environmental conditions. Strong diffraction ability;
