CONSISTEL maintains very high standard in implementing in-building
networks. While not disturbing the ambience of the building, we
make use of the available resources to provide a cost-efficient high
quality network.
Cable Routing
Cable risers inside the building will serve as the main distribution
points for the feeder cable distribution system on the various floors
of the building. Efficient utilization of the cable risers ensures
that feeder lengths are minimized, thus minimizing the feeder losses
as well as material cost. This allows for a more robust link budget
that translates into improved signal strength on both the forward
and reverse links. Feeder routes on each floor are chosen to minimize
installation difficulties by avoiding private enclosed areas such
as shops and offices.
Antenna Location
Antenna locations are important in maximizing the coverage areas
by avoiding shadows, capitalizing on the propagation gain effect
along corridors and identifying important coverage areas like car
parks, lobbies, restaurants, shops and reception areas. Customers
can specify the area to be covered. The antennas will be small and
positioned in such a way that indoor structural aesthetics is not
compromised. The antennas will be installed on the ceiling and
walls. Moreover, they will be positioned to decrease uplink interference
and downlink emission while providing very good coverage to the
interior of the building.
Handover
There shall be sufficient overlap between the coverage footprint
afforded by the relevant antenna elements with the existing outdoor
coverage so that indoor-to-outdoor and outdoor-to-indoor handovers
can be performed smoothly without the incidence of dropped calls.
At the same time, unnecessary spillage of the indoor signals into
the outdoor cells are avoided by proper selection of antenna types
and antenna positioning, as well as proper signal strength. Difficult
and/or unique handover optimization can be resolved by using the
propagation models and simulation, high-end data capture/analysis
and measurement tools.
Expansion Flexibility
The design is designed to cater for further expansion with minimal
modification of the RF distribution network. Such expansion may
be for purposes of improving coverage or capacity, or to cater for
emerging new technologies.
