3.3 Multiple bands

The flexibility of the system allows for up to 4 bands in one remote for the low and medium power

remote units. The high-power version allows 2 bands in the same chassis, mainly because the power

amplifiers are more bulky.

This means that it is very easy to deploy a system for different bands. The fiber link is ultra wide band

and can be used between 88 MHz up to 2 700 MHz thus covering from the VHF end of the spectrum up

to the latest LTE bands.

Each band needs to have their separate BIU in the Master Unit. The uplink and downlink signals can then

be combined in the POI or may be separate all the way into the FOI. The FOI has two inputs and outputs

and can thus be connected to two bands directly.

Here is a block schematic on how to connect a dual band system.
