1.4 Britecell Plus typical Applications
Thanks to its unique features Britecell Plus is the ideal solution to set up radio coverage in may
situations:
• Multi operator shared infrastructure: each mobile operator has its own carriers, which
must be transported without affecting the others. Britecell Plus is capable of transmitting
multiple carriers simultaneously, while providing an independent level adjustment for each
of them, ensuring maximum performance and reducing infrastructure costs
• High rise buildings: RF signals from surrounding macrocells or external BTSs are usually
quite strong inside high rise buildings, and cause so much interference that indoor mobile
communications often become impossible. By strategically placing antennas along the
exterior walls of the building, the signal to noise ratio can be optimised. This interference
control solves many problems, such as the “ping pong” effect that sometimes is experienced
when a mobile frequently changes from an indoor to an outdoor coverage.
• Exhibition, conventions, and shopping centres: the critical point of these environments is
due to the high traffic loads, which are furthermore highly variable. Thus, the main goal to
achieve is setting up a radio coverage which could effectively manage these variable traffic
loads, with neither undervalued nor overvalued infrastructure expenses. A unique feature of
Britecell Plus is that RF frequencies can be allocated quickly when and where they are
needed, thus reducing the implementation cost. This makes Britecell Plus the proper solution
also for temporary or last minute requests (such as conferences).
• Airports: they require modular and flexible radio coverage, in order to meet present needs
while foreseeing future expansions. Britecell Plus can manage high traffic loads providing
high quality with minimum environmental impact, while its modularity allows future
extensibility.
• Corporate Building: inside a corporate building, difficult mobile communications may limit
business transactions. These environments are often complex and densely populated with
specific requirements to be fulfilled: high traffic capacity, maximum expectations on Quality
of service, full compatibility with wireless standards and future expandability. Britecell Plus
guarantees high quality radio coverage 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.
1.5 Health and Safety Warnings
IMPORTANT NOTE: To comply with FCC RF exposure compliance requirements, the following
antenna installation and device operating configurations must be satisfied: A separation distance of
at least 35 cm must be maintained between the antenna of this device and all persons. RF exposure
compliance may need to be addressed at the time of licensing, as required by the responsible FCC
