Following are the descriptions of the RND services.
New Network Design
A new radio network is designed for a defined service area where the operator has not service earlier. The network will have relatively few subscribers when service is initiated. Therefore the planning strategy would be based on quick expansion of the coverage at the beginning.
Macro Cell Expansion
The number of macro cells in the existing network is increased by adding new sites and/or adding new cells to the existing sites. The geographical area covered by the new cells/sites are in or adjacent to an area were the operator already provides service. The objective is to increase subscriber capacity or improve coverage/quality. The new cells will have a substantial amount of subscribers from the day one.
Micro Cell Expansion
New micro cells added to the existing network mostly in order to provide more subscriber capacity for a limited area or to relief the congestion on the macro sites. Typically it can be a down town area where a set of micro sites are installed with the antennas located below roof level.
Indoor Design
A particular indoor cell/site is planned within an existing network in order to increase the capacity or improve the coverage/quality for an indoor environment such as office hotels, shopping malls.
Dual Band
Number of available radio frequency channels increased by adding some from a different frequency band. So the existing network would be expanded in terms of capacity using new allocated frequencies that will not interfere with the ones already in use. This is done by adding new sites to the network either at the same locations with existing ones or by using new site locations.
Frequency Re-planning
Existing frequency plan of the network is replaced with a new frequency plan in order to improve the quality and thereby the performance of the network.
Tighter Frequency Reuse
A tighter frequency reuse makes it possible to release frequency spectrum to be used either for more transceivers per cell, so that to increase the capacity or to implement GPRS/EDGE. It is important to reduce the interference of the network in order to proceed with the tighter frequency reuse.
GPRS/EDGE Radio Network Design
Activities required for planning a GPRS/EDGE network are carried out under this service. It includes assessment of end-user throughput, setting of radio parameters and tuning of the radio network.
