Radio Network Planning

Overview

Radio network operators are passionate about efficiency – getting the maximum return for the minimum outlay. Planning a network with the least amount of base stations to meet service requirements is one way to achieve that.

Part of radio network planning is modelling. Modelling answers questions like whether a proposed new service can be slotted into a spectrum space without causing interference. Radio network modelling provides answers before the operator incurs outlay costs or services suffer as a result of interference.

Network optimisation improves network coverage and the quality of signals. Whether this is achieved by automated frequency planning (AFP) or other methods, network operators worldwide are adopting sophisticated optimisation techniques to improve their network performance.


Benefits

RF Planning

Radiofrequency planning includes network planning, design and optimisation. These functions enable network operators to build flexible wireless networks which can grow to meet increases in traffic and subscribers. At this stage of network development, it is important to ensure the network is rolled out faster, performs better and costs are kept to a minimum.

But today’s networks demand so much more. Engineers need to manage in-building coverage, small cell planning, backhaul or transmission network planning. All these activities need overseeing while ensuring the network delivers the coverage and capacity to meet the needs of the data-hungry subscribers.

Automatic Frequency Planning

AFP is used by operators worldwide as a method of optimisation. It is based on sophisticated techniques which control automatic frequency planning and optimisation of TRX allocation versus interference conditions. This method incorporates specific advanced features such as the allocation of frequency hopping parameters, intermodulation, multi-layer analysis, inter-system interference, use of the neighbour list, and user-definable constraints, enabling automatic frequency network planning, including worst-case scenarios in dense urban areas.

Support

HTZ provides incorporates the latest ITU propagation and prediction models. These propagation models enable the software to provide accurate results. The main network planning and analysis features include:

  • Prospective planning to identify the best locations for new sites for greenfield and densification scenarios;
  • Migration analysis from analogue to digital communications;
  • Analysis of outdoor to indoor coverage by signal penetration loss calculation;
  • Population analysis from points, areas by vector polygon imports or raster files;
  • Coverage studies including network coverage, composite coverage, overlapping, best-server and network densification;
  • Propagation model tuning by analysing the correlation between prediction and measurement;
  • Automated frequency assignment and optimisation;
  • Traffic analysis from ground occupancy, target areas or mesh blocks to cover;
  • Point to Point network analysis including path profiles, reliability analysis, automatic optimisation, frequency and space diversity and frequency analysis;
  • Simulcast planning and analysis.
