Network planning Network planning is the initial phase of a new network roll out or technology enhancement. The overall goal in any network is to deliver the required coverage and capacity and to fulfill quality of service targets while meeting defined financial objectives.

The widespread use of smartphones, the proliferation of new data-intensive services and consistent traffic growth drive mobile operators to continue to invest in the network. But with the average revenue per subscriber (ARPS) falling, correct planning is crucial to focus and optimize such investments. Network planning starts with several critical business decisions, including defining financial targets and setting performance objectives for coverage, capacity and QoS. These objectives drive the link budget calculations, which in turn influence network infrastructure selection, channel propagation...

Base station lab testing The performance of a wireless network infrastructure, e.g. transmit power, downlink timing error and receive sensitivity, has a critical effect on the overall network performance. Selecting equipment such as components, modules and even the entire base station with the right specifications is therefore a key decision. RF characteriszation of network equipment can be done by performing user-defined receiver, transmitter and performance tests or by verifying that the equipment complies with 3GPP standards. Rohde & Schwarz test equipment such as spec- ¸SMW200A  vector signal Ggenerator ...

Spectral clearance It is often necessary to re-deploy or eliminate existing transmitters to ensure a clean RF environment before deploying additional transmitters in a network. This process, known as spectral clearance, requires an appropriate RF scanner such as the ¸TSMW to fully capture all the signals present in the band of interest and then plan the spectrum for future use. Using a mobile device for this would be too slow and would not have the necessary accuracy or sensitivity. Often existing broadcast and cellular services are moved from one frequency band to another to make way for the...

Network deployment Mobile network operators deploying, upgrading and maintaining their networks require portable field tools to measure the performance of the BTS infrastructure.

During this phase, a new cell site must be installed, commissioned and verified in accordance with a predefined test procedure to ensure its performance when operational. Handheld field test tools enable measurements such as VSWR, distance-to-fault and spectrum measurements to be made either by direct connection or over-the-air using an appropriate antenna. Test tools must be adaptated to the type of network architecture, from macro cells to remote radio heads and DAS systems, to take into account connectivity, power and performance specifications.

Network optimization To achieve optimum network efficiency and ensure the required RAN coverage, network optimization is required.

Drive tests, walk tests or fixed probes are used to measure network coverage and performance. The results are analyzed using sophisticated software such as ¸ROMES4 to identify potential areas for network improvement. Benchmarking uses the simultaneous measurement of multiple cellular networks to evaluate the relative performance of each network. This process shows the operator the strengths and weaknesses of his own and competitor networks for the purposes of strategic network development and marketing. Rohde & Schwarz and SwissQual offer a wide variety of optimization and benchmarking solutions...

Benchmarking For mobile operators, subscriber quality of experience (QoE) is one of the key factors driving revenues and reducing churn. Benchmarking your network performance against the competition is an effective way to really understand relative competitive performance to identify needed improvements and to trigger strategic investments. It is also an effective way of getting to know the competition and of gathering valuable information as a source for focused promotional campaigns.

Network operation Once a network is operational, the task is to understand its performance in realtime, to run it efficiently and securely and to identify and rectify faults when they occur. To run a network efficiently and ensure subscriber quality of experience (QoE), it is necessary to monitor the level of service experienced by subscribers in the RAN and monitor IP traffic on the network to identify and rectify faults quickly and efficiently. This requires probes such as the SwissQual Remote Control to be placed in the RAN and probes such as those from ipoque in the core IP network. These...
