Multiple Access Communications Limited (MAC Ltd) was founded in 1986 and the company has a wealth of experience in the specification, design and implementation of radio systems, particularly at the lower layers of the protocol stack, namely, the physical (PHY) layer, the data link layer and the network layer. It has been at the forefront of the software defined radio (SDR) revolution and it has world-leading expertise in implementing designs on a range of different SDR architectures and platforms.

Building on our heritage in the mobile cellular industry from the early days of GSM (2G), we have worked on all of the subsequent generations (3G, 4G and now 5G) as well as on many allied technologies such as TETRA, Bluetooth, WiFi, Zigbee and satellite systems. We have an in-depth knowledge of the fundamental technologies on which these systems are built, including radio frequency systems, modulation, error correction coding, equalisation and multiple access schemes, and the ways these technologies are applied.

MAC Ltd is privately-owned and independent, hence when you work with us you can be sure of impartial advice and no conflicts of interest. We have been helping our clients with the analysis, evaluation, design and development of advanced mobile radio technologies and equipment for over 30 years, so you can be sure that our work is built on solid foundations and a strong reputation.

We offer a range of services including modelling and simulation, digital signal processing (DSP), field-programmable gate array (FPGA) design, embedded software development, bespoke hardware design and much more. More than anything we like a challenge and our clients return to us because we have a track record in solving difficult problems and handling complexity.
