2.4. TYPICAL ION-B APPLICATIONS
Due to its unique features, the ION-B is an ideal solution for radio coverage in a variety
of situations:
Multi-operator shared infrastructures: each mobile operator has its own carrier which
needs to be transported without interfering with the others. The ION-B is capable of
transmitting multiple carriers simultaneously while providing independent level
adjustments for each of them, ensuring maximum performance and reducing
infrastructure costs.
High rise buildings: RF signals from surrounding macro cells or external BTSs are
usually quite strong inside high rise buildings and can 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
optimized. This interference control solves many problems, such as the “ping pong”
effect that sometimes is experienced when a mobile frequently changes from indoor to
outdoor coverage.
Exhibitions, conventions, and shopping centers: the critical aspect of these environments
is their high traffic loads, which are furthermore also highly variable. Thus, the main goal
in these cases is to set up radio coverage enabling the effective management of these
variable traffic loads, with neither undervalued nor overvalued infrastructure expenses. A
unique feature of the ION-B is that RF frequencies can be allocated quickly when and
where they are needed, thus reducing implementation costs. This makes the ION-B an
ideal solution for temporary or last minute requests (such as conferences).
Airports: require both modular and flexible radio coverage in order to meet their current
needs while also foreseeing future expansions. The ION-B is able to manage heavy
traffic loads, providing a high level of quality with minimum environmental impacts, its
modularity also allows for future expansions.
Corporate buildings: inside a corporate building, frequent disruptions during mobile
communications may limit business transactions. These environments are often complex
and densely populated while having specific requirements: heavy traffic capacity, high
expectations regarding quality of service, full compatibility with wireless standards and
future expandability. The ION-B guarantees high quality radio coverage in all of the
above conditions and maintains maximum flexibility while managing any possible traffic
conditions.
Subways and densely populated metropolitan areas: These areas are distinguished by
large surface areas, and may require RUs to be placed far away from the BTSs. The
ION-B guarantees signal integrity for distances up to 3km, while through the wideband
interconnect link option, distances of 20km can be reached. Moreover, these
environments require gradual investments, because initially operators tend to provide
radio coverage only in the busiest areas, and then extend it in order to reach complete
coverage later.
The modularity of the ION-B helps operators to gradually expand the system. Often,
large cities set up seamless and reliable radio systems for emergency services. In these
cases, the required RF infrastructure needs to be unobtrusive and environmental
friendly; this can be achieved using an ION-B DAS. When redundancy is required, two
interleaved ION-B 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.
