Central Receiving System - Gigawave

The Central Receiving System coming from the manufacturer that always breaks new ground in the field of professional microwave transmission provides an alternative to the satellite transmitter devices of ENG crews at a good cost-benefit ratio, especially in cities where need arises regularly for live broadcasting and reports.
The antennas and the multi-channel, diversity-operating microwave units of the receiver can be installed on top of any high building in the city or on a relaying tower set on a nearby mountaintop.
From such points of vantage perfect coverage can be achieved for the whole city.
The ENG crew relays its material to these receivers – instead of a satellite uplink –, and the device transmits them via a leased line or microwave connection to the studio.
The signal transmission between the cameras and the receiver is handled by digital COFDM modulation, assuring low latency, error free transmission.
Thanks to the Maximum Ratio Combining diversity method the transmission is resistant to signal loss or fading due to non-singular spreading. This assures a higher level of stability during operation, as well as greater transmission distances.

If short range radio transmission is required, the manufacturer’s camera mountable, omnidirectional D-Cam Clip-On microwave transmitter is usable. With its weight of barely 1 kilogram, it provides the cameramen with unlimited mobility even on occassions where cable based connection is impossible to implement.
The range of the microwave transmitter can be highly increased by the use of power amplifiers and directed helix antennas.
The frequency range of operation of these transmitters is between 1,3-7,5 GHz. Since in Hungary the use of the 2,4 GHz frequency is free of charge and requires no registration, such subsidiary expenses are negligible.
