Who We Are

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 wireless systems.  Building on its heritage in the mobile cellular industry from the early days of GSM (2G) MAC Ltd has 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, eg, radio frequency systems, modulation, error correction coding, equalisation, FDMA, TDMA, CDMA, OFDM, and also in the specific ways these technologies are applied in the many commercial standards.

Multiple Access Communications – 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 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.

On this website, you will find a summary of the services that the Company offers, which cover modelling and simulation, digital signal processing (DSP), field-programmable gate array (FPGA) design, embedded software, hardware design, user interface and database software 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 or handling complexity.

So, if you need a solution to a problem in your project and you need help, please feel free to give us a call or email us using this link click here and we’d be happy to take up the challenge.

Expertise in radio communications technology is the foundation of our business.
