3GPP Release '99 (June 2012)

CCww's protocol stack technology is used on >3B handsets world-wide, and - in 2020 - customised and supported world-wide.

It was designed in the late 1990s, using the latest CASE tools, and hand-coded by engineers with experience of GSM that extends back to 1988, providing a resource-lean implementation which is low on latency and high on quality. As well as supporting 3rd party licensees, our engineers, in conjunction with our partners, have developed a range of products and reference designs, ranging from handsets to M2M devices, and they continue to develop and maintain the protocols to guarantee reliable service world-wide.
