1 SYSTEM DESCRIPTION
The MBF - Multi-Band Fibre optic fed system encapsulates solutions for both indoor and outdoor
environments for single or multi-operator use. It offers seamless coverage in any indoor environment
such as tunnels, metros and larger buildings.
Signals are coupled off from a nearby base station and then distributed via fiber to one or several
MBF repeaters.
Up to 5 frequency bands can be supported over single F/O cable to allow future upgrades w/o the
need to add additional cables, done thru master unit (with F/O interface) and slave unit ( w/o F/O)
connected to the master unit.
The high output power of the remote unit results in a need to deploy a fewer number of sites, which
in turn lowers the capital expenditures for the roll-out as a whole.
These remote units can be installed up to 12.5 miles (20 Km) from the base station site, offering a
great flexibility when providing RF coverage in areas where off air transmission is not a preferable
solution. A distributed antenna system can be used to distribute the signal throughout the area to be
covered.
Cobham Wireless can provide a complete solution including design, site surveys and equipment
related to the POI (Point Of Interface) such as combiners, filters, cross band couplers, etc. The MBF
product family includes version for single band, dual band, tri band and quad band variants available
in various combinations.
