FH1G4 – Microwave link

Range of economical narrowband microwave links which enables to extend private communication networks on large distances: up to 150km in function of the antennas installation

Category: .

The FH1G4 numerical microwave links use the open European frequency band for fixed links, arround 1,4 GHz

They can transfer data, voice and images.

It is a very economical solution compared to recurrent costs on leased lines.

Several product options enables the construction of point-to-point networks, point-to-multipoint networks or linear networks with multiple repetitions, for very extended coverages.

When integrated in a SCORPION infrastructure, these radio beams can constitute a solid backbone accross several departments with a high redundancy rate.
