Digital Microwave Radios: E1 and Ethernet Radios
- Solutions for 5.8GHz, 7GHz, 8GHz, 13GHz, 15GHz
- PSK and 16QAM modulation options
Valiant offers its latest E1 Digital Microwave
solution for wireless transmission
Valiant's offers a rugged and a very reliable Wireless
Digital-Microwave solution which may be used to transmit up to 16 E1 channels (or E1
channels plus an Ethernet Channel) up to a distance of 40 KM in a
"line-of-sight" installation.
Valiant's Digital-Microwave Radio solution consists of a
1U, 19-Inch Rack-Mountable Indoor Unit (IDU) and a very compact, pole-mountable Out-Door
Unit (ODU). |

The 1U, 19-Inch Rack-Mountable Indoor Unit (IDU) may be
powered from a nominal - 48V DC power input (acceptable DC voltage input range is - 40V DC
to - 60 V DC).
The ODU (Out-Door Unit) is packaged in a weather-proof,
rugged pole-mountable units which is powered from the IDU (Indoor Unit) through it's
single antenna cable.
Valiant's Digital-Microwave Radio solution is provided with
advanced internal diagnostics capabilities which enables it to offer reliable performance
even under the most difficult and harsh conditions. The equipment is also available
(optionally) in a 1+1 protected package.
