5.3.6 Scanning Mode of IRCU
For compatibility with different BTS/NodeB, Comba R&D designs 2 different modes of IRCU
scanning: Single-mode and Multi-mode*. IRCU-302, IRCU-502 and IRCU-602 both support
Single-mode and Multi-mode, IRCU-C414 and IRCU-C814 support Single-mode.
Single-mode is the default setting for all IRCU but both modes actually have no difference in
term of function controlling. Taking IRCU-302 for example, being used in 3 frequency band
build-in RCU RET antenna and in 3 sectors deployment as shown in Figure 12:

*If operators wish to use multi-mode, kindly contact supplier to provide .bin file configuration.
