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 automatic frequency planning (AFP) or other methods, network operators worldwide are adopting sophisticated optimisation techniques to improve their network performance.
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.
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.
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:
