10. Application Scenarios
This section describes various configuration scenarios for the CrossFire.
10.1. Operators Located at Same Site
In this example, operators A, B, C, D and E are located at the same site (see Figure 10-1). Operators B and C operate
in the same frequency band, which can be combined in one channel in “the RF domain”. The maximum bandwidth per
operating band should be less than 60MHz and the maximum bandwidth of all operators should be less than 200 MHz.

Figure 10-1 Example for Operators Located at Same Site
10.2. Operators Located at Separate Sites
In this example, operators A, B, D and E are located at one site and operators C and F are located at a different site.
(See Figure 10-2) Operators C and F can access the Master AU through the Slave AU so that all operators can combine
within the same fibre from the Master AU to the EU. In contrast with the scenario in section 10.1, operators B and C can
be combined in the “baseband domain”. The maximum bandwidth per operating band should be less than 60MHz and
the maximum bandwidth of all operators should be less than 200 MHz.
