under all conditions, while maintaining maximum flexibility in managing
any traffic condition.
• Subways and Highly Dense Metropolitan Areas: These areas are
distinguished by large distances, and may require that RUs are placed
far away from the BTSs. Britecell Plus guarantees the signal integrity at
distances up to 3 km, and through the wideband interconnect link
option distances of 20 km can be reached. Moreover, these
environments need gradual investments, because initially operators
provide radio coverage only in the busiest areas, and then extend it in
order to reach complete coverage. The modularity of Britecell Plus helps
operators to gradually expand the system. Some large cities often need
to set up seamless and reliable radio systems for emergency services.
The required RF infrastructure needs to be unobstrusive and
environmental friendly; this can be achieved using a Britecell Plus DAS.
When redundancy is required, two interleaved Britecell Plus systems can
be used, management and supervision for these systems can be
remotely established by means of an external modem and an open
protocol such as SNMP.
