Wireless Design
Ranplan is dedicated to providing a service to the wireless telecommunication industry which ensures that our customers are provided with the best possible products and services, whilst endeavouring to achieve the most efficient cost and performance specifications, and provides consulting and training services for Wi-Fi, UMTS/HSPA, TD-SCDMA and WiMAX planning.
The aim of our wireless division is to research and develop automatic planning and optimisation (P&O) tools for emerging broadband radio access networks (RANs) such as High Speed Packet Access ( HSPA ) and WiMAX (the Worldwide Interoperability for Microwave Access) and the hybrids of such networks with Universal Mobile Telecommunications System (UMTS) and Wi-Fi, i.e., Heterogeneous Radio Access Networks (HRANs).

Planning & Optimisation
Services to industry in the area of automate HSPA (HSDPA/HSUPA) planning and optimisation.
Novel approaches to automate WiMAX PMP (Point to Multiple Point) & mesh modes planning & optimisation.Develop novel approaches for automatic joint planning and optimization of hybrid Wi Fi/UMTS/HSPA/WiMAX networks.

Distributed Simulation & Planning
Develop efficient parallel and distributed simulation and planning methods that can improve the performance and accuracy of RAN and HRAN P&O.
The current main focus of Ranplan is on the R&D of advanced radio network planning and optimisation tools. The project currently we are working on that will lead to commercial automatic RAN planning tools that can be used to plan and optimise some emerging broadband RANs such as HSPA, WiMAX, and their hybrids with 3G and Wi-Fi networks (i.e., HRANs). These tools will provide some 20-30% performance improvements for RAN/HRAN and can be used to plan environment friendly wireless infrastructure with less health concerns.
Our research topics are very important for Wireless infrastructure. The project is highly interdisciplinary as it covers wireless communications, Operations Research (OR), and High Performance Computing (HPC).efficient use of the channel by adapting, for example, AMC (Adaptive Modulation and Coding) techniques.
A coverage model is under developing that will describe the size of the network and its coverage (e.g., using link budget). The planned overall capacity of the network is to be described in a capacity model. This capacity model will be used to ensure that WiMAX Base Stations (BSs) do not become overloaded. Finally, a subscriber traffic model will be developed, which will reflect the traffic density, distribution of a certain area.

WiMAX Simulator Development
Planning-driven WiMAX Modelling, analytical models are developed for WiMAX P&O. In this area, ranplan is developing a simulation platform for WiMAX P&O. WiMAX is a complex wireless system that supports various services with different QoS requirement; For a complex wireless system like WiMAX, simulation methods are normally more accurate than analytical approaches. In our current project, the existing simulation methods for WiMAX is reviewing, we are developing a simulator that can be used for WiMAX P&O. It is expected that the WiMAX simulator will be adapted from the RAT (Radio Access Technology) simulators developed by project partners.

Development of Automatic WiMAX P&O Methodology and Toolkit
In order to automate WiMAX planning, the WiMAX BS locations and parameters selection problem should be formulated as a combinatorial optimization problem, and solved by optimization algorithms. Our Development of Automatic WiMAX P&O Methodology and Toolkit is best kit for The automatic WiMAX P&O methodology, which consists of an optimisation framework, analytical models and WiMAX simulator).

WiMAX optimisation framework and cost function design
In this field, a multi-objective optimisation framework is used to automate WiMAX P&O. infrastructure cost, coverage, network performance (e.g., throughput under a certain routing algorithm), interference, and network resilience. In addition, the radio wave pollution problem will also be taken into account. This multi-objective optimisation problem can be solved either by using RANPLAN Parallel front.. A number of solutions will be offered to reduce the time & costs. The combination of both analytical approach (much quicker than simulation approach) and simulation method (more accurate than analytical approach) will be used to improve the speed of optimisation. Solution oriented approach as discussed in WiMAX P&O Methodology and Toolkit will be explored. New “intelligent” optimisation algorithms, which can “learn” from previous searching results and instruct next “moves” accordingly, is under RANPLAN developing. e.g., parallel optimisation algorithms and parallelised WiMAX simulators.

Development of Automatic WiMAX P&O Toolkit
Based on the research developed in WiMAX optimisation framework and cost function design, Ranplan is dedicate main focus to developing automatic WiMAX planning and optimisation toolkit that comprises of various WiMAX models, simulator,and optimisation algorithms.
