Cuts number of base stations required by up to a fifth
Bristol, United Kingdom - ProVision Communications has released an
enhanced version of its WiMAX network site optimisation tool ProSiteTM
that will bring significant cost benefits to service providers and WiMAX
equipment vendors. The tool enables WiMAX networks to be much more
accurately planned, potentially resulting in a dramatic reduction in the
number of base stations required. |

“This has obvious
competitive benefits to WiMAX vendors when bidding on large contracts by
reducing their base station costs by as much as 20%, and at the same
time lowers contract risk by increasing confidence in the precise number
and location of base stations needing to be deployed” said Dr. Nicolas
Lodge, CEO of ProVision Communications.
In using this enhanced optimisation tool the network planner works from
an initial list of sites known to be available to achieve a fully
optimised network design; this avoids theoretical solutions containing
unobtainable sites. The new ProSiteTM optimisation tool considers both
technical and financial data to select the minimum and lowest cost
subset of sites that meet a particular user defined coverage and/or
capacity requirement. The user-supplied list of possible sites can
contain existing sites which must be included in the final optimised
solution. Hence ProSiteTM can assist in planning the growth of an
existing network as well as plan for an entirely new network. Financial
costs (such as equipment rental and operating costs) are considered
alongside technical data (e.g. sector transmit powers, total capacity,
frequency assignment etc.) for each site. ProSiteTM allows a
user-specified frequency plan for coverage and capacity optimisation.
Subscriber locations can be loaded from a file or manually specified
using the supplied GUI. The network planner can specify the requested
traffic level (data rates) for subscribers, as well as the unit charge
for the traffic type (i.e. cost per Mb of traffic). This enables
ProSiteTM to estimate the potential revenue for each optimised solution.
Coverage and capacity constraints are specified using user-defined link
quality metrics. The system offers a ranked list of solutions, and
allows ranking based on various considerations e.g. coverage percentage,
total number of sites, total cost, projected revenue, etc.
ProSiteTM works in conjunction with ProPhecyTM, the world-leading WiMAX
propagation planning toolset developed by ProVision Communications. This
new enhanced version of ProSiteTM can also be used with third party
prediction data derived from other planning systems to provide similar
benefits.

About ProPhecy
ProPhecy is ProVision Communications’ state-of-the-art suite of tools
for modelling wireless propagation in urban and semi-urban areas. Unlike
previous generations of wireless planning tools, it provides highly
accurate predictions for non-line-of-sight wireless propagation, making
it particularly suitable for the planning OFDM systems such as WiFi
hotspots, WiMAX networks, and DVB-T/H television networks. ProPhecy uses
a unique building and terrain scatter model, including foliage loss
modelling, which scales to enable areas of up to 50km x 50km to be
analysed in true 3D. Designed to work with low cost LIDAR geographic
data, it is much less expensive to operate than traditional systems that
require vector data. |
