3.2 Radio Units
The radio units are continuously developed and improved regarding design
and technology. Two types of radio unit are available, RAU1 and RAU2. They
have the same functionality, but different mechanical design and microwave
technology. RAU2 has a higher integration of microwave circuits.
The radio units are independent of traffic capacity, that is the operating
frequency is determined by the radio unit only. The operating frequency is set
on site. This is done with the management software products or with a toggle
switch on the indoor M MU.
The radio unit is a weatherproof box painted light gray, with a handle for lifting
and hoisting. It connects to the antenna unit at the waveguide port. The radio
unit also has two hooks and catches to guide it for easier handling, when fitting
to or removing from an integrated antenna.
Radio units are available for different frequency channel arrangements
according to ITU-R and ETSI recommendations. For detailed information on
frequency versions, see Section 8 on page 125 and the MINI-LINK E and E
Micro Product Catalog (AE/LZT 110 2011).
