Authors from MAC Ltd Awarded ‘Best Paper’ at International Conference

Two authors from Multiple Access Communications Limited (MAC Ltd), Dr Ying Li (Principal Engineer) and Peter Gould (Consulting Services Director), have had their paper entitled ‘A Low Cost Adaptive Wireless Sensor Network for Accelerometer Data Collection’ selected for a ‘Best Paper’ award at The Seventh International Conference on Adaptive and Self-Adaptive Systems and Applications (ADAPTIVE 2015). The paper was presented by Dr Li at the conference, which was held in Nice, France on 22 – 27 March 2015. The work presented in the paper was performed as part of a collaborative research and development project, co-funded by Innovate UK, which is examining the use of wireless sensor networks to monitor the condition of railway infrastructure by embedding sensor nodes into railway sleepers. The other collaborators in this project are the Buildings Research Establishment (BRE) and Cemex Rail Products.

2.3 GHz Interference Studies Published

Multiple Access Communications Limited (MAC Ltd) was recently engaged by Ofcom to investigate the potential impact of interference from new LTE systems deployed in the 2.3 GHz frequency band on Bluetooth and ZigBee devices operating in the adjacent 2.4 GHz ISM band. MAC Ltd was selected to perform this work after a competitive tender process and it used its extensive expertise in these mobile communications technologies to design and implement appropriate test set-ups to generate the necessary information required by Ofcom to inform its plans for the release of the 2.3 GHz frequency band. The final reports from the Bluetooth and ZigBee interference studies are available on Ofcom’s web site at

Smart Green Railway Sleeper Research

Multiple Access Communications Limited (MAC Ltd) is pleased to announce its participation in an innovative and collaborative research project entitled Smart Green Railway Sleepers, which brings together new manufacturing techniques in concrete and the use of embedded wireless sensors. The project is co-funded under the Technology Strategy Board’s recent ‘Materials innovation for a sustainable economy’ competition and is led by the Building Research Establishment Limited. The research consortium also includes Cemex UK Limited, the largest supplier of concrete sleepers and crossing bearers to the rail industry.
