Cell Planning
This allows the Operator to develop a strategic and tactical plan to establish and provide for the new network. It includes analysis of coverage, end to end capacity requirements, sites that are potentially available, allocated frequency utilization and other information.

	Map data handling and propagation model optimization
	Nominal cell planning
	Site selection
	Final radio network design
	Verification of radio network design

Coverage Expansion
This provides the Operator with a plan for expanding the coverage of the cellular network. This plan includes information such as equipment specification, the number of sites, and use of frequencies and channels. It also includes a rollout plan and a suggested schedule and strategy for implementing the network.

	Nominal cell planning
	Site selection
	Final radio network planning
	Verification of radio network planning

High Capacity Planning
This service provides the Operator with a plan for expanding the capacity of the cellular network with minimum capital expenditure.

It provides advice on additional equipment and features as well as the number of additional cells needed to meet capacity requirements. It provides an evaluation of potential sites and the use of frequencies and channels.

It also includes final tuning and verification of quality. Final tuning verifies that the solution we propose fulfils all the Operator's high capacity planning requirements.

Core Network Design
The core network is designed from perspectives of cost effectiveness, grade of service, capacity, robustness and redundancy, while allowing for future expansion and reengineering as new services and features are planned. We provide services such as:

	Network architecture
	Network element design and dimensioning
	Circuit switched and packet based transport network design and dimensioning design
	IN systems design and dimensioning

PNN’s Network Thinning services help maximize site utilization and optimization in a network. By achieving networks with a reduced number of sites and ensuring the network performance, operators realize monetary savings on leasing cost reduce operational expenditure and ensure efficient management of the network on all technologies.

Network Optimization Services
Having rolled out and commissioned the network, ongoing optimisation is required as the network grows and voice and data traffic increases. New network features can be enabled to enhance capacity and quality of the installed network.

	Radio Network Audit
	Radio Network Improvement
	Radio Network Benchmarking
	Core Network Audit

Radio Network Audit
This desktop review service focuses on network analysis for a fast status check of the network performance. It compares the Operator's network performance indicators with an industrial average and provides a benchmark indicator. The review can be adapted to include all network elements, transmission links and air interface performance, or focus in on only one particular domain. The service produces a detailed report highlighting areas of the network where improvements in quality and capacity are possible.

Radio Network Improvement
This is a service for advanced on-site detailed investigation of the radio network for cellular users. It is designed to allow the Operator to offer an optimised quality service to its subscribers and to get the most efficient use out of the various radio network features and elements of the cellular network.

We provide a detailed report that covers the performance of the radio network, a summary of the tuning activities, and our recommendations on how the Operator can improve its service in the short to medium term.

Radio Network Benchmarking
This service is offered to commercial wireless telecommunications operators who desire to track their perceived network quality relative to other competitors in the same operating environment. This is carried out through network drive-testing in the area of interest as well as customer experience surveys.

Advanced post-processing tools are used for data gathering and analysis.


Core Network Audit
This service performs health check on core network infrastructure. Signaling systems, voice and data traffic interfaces, and network elements are checked for capacity headroom or shortfall for given traffic needs. Processor load and I/O systems of critical switches are checked for correct run time operation capability. Risk of congestion and potential bottlenecks in network elements or transport links are identified and remedial action recommended.

State of the art modeling tools are utilized to provide traffic trends and early impact assessment of proposed network reconfigurations or enhancements. Traffic and network data is extracted from the network elements and analyzed and an audit report is prepared highlighting all aspects of the network indicating its health status.

Core Network Improvement
This service takes the core network audit a step further and executes the remedial actions required to make the core network more robust, less congested and more efficient in its utilization of the installed infrastructure. The network is benchmarked against best in class industry standards in terms of its performance in service availability, capacity, quality, robustness, and cost of operation.

Traffic and network data is extracted in the same manner as the network audit, but with the remedial actions being implemented to deliver to new improvements to achieve best in class performance.

Network Management
The network management services suite covers all aspects of operating and maintaining a cellular network including:

	Data (re)configuration
	Integration of new network elements for expansion
	Re-engineering, expansions
	Network interconnects
	Fault alarm management, fault localization and troubleshooting
	System upgrades and enhancements
	System upgrades and enhancements

The service is normally centralized at the operators network operation centre and also includes site maintenance teams who continuously monitor and maintain all cellular sites throughout the network.

Experienced Network Operation engineers are provided to execute the critical functions of network management and also provide advice and guidance to the operator on achieving best in class streamlined processes ensuring maximum performance of the entire network.

Competence Transfer and Consultancy
For operators wishing to train personnel in all aspects of network planning, implementation, operation and maintenance, PNN offers guidance on how this may be achieved in the fastest and most cost effective manner. Training needs analysis are initiated for the operator’s network engineering personnel where specific and focused theoretical and practical training programs are identified to meet necessary competence requirements in running an efficient and high quality network.

Ongoing network consultancy and support is also available to the operator to assist in maintaining a finely tuned network management organization and provide guidance in managing the evolution of the network.
