Figure 1.3 SATELLAR XT 5RC with display (on down left), SATELLAR XT 5RC without display (on down right) include RU
and CU. These types are used, when a local Ethernet connection is needed.
Range
In the RU of the SATELLAR the communication range of a point to point link is typically longer than 10 km
in urban conditions (some obstacles in the line of sight), and longer than 20 km in line of sight conditions.
Significantly longer range can be achieved, depending on radio conditions, antenna selection etc. The
range can be further extended also by using the radio repeaters.
Security
Data security is often a concern when using radio communication. In the SATELLAR a 128-bit encryption
on the air-interface ensures privacy in the radio network. With QAM-radio also the 256-bit encryption is
supported.
Flexible and expandable
The SATELLAR concept has been designed to be flexible and expandable both in terms of hardware and
software functions. This can also be seen when using the RU alone.
