A modem is a classical embedded system, requiring low cost and low power, having to meet stringent timing constraints and low failure rates. But recently we have seen the emergence of CloudRAN and ORAN, both of which claim to take all, or at least some, of the modem functionality into classical server software environments, such as Kubernetes. So what is going on here? The answer is a complicated mixture of pressures all applying themselves at once, from the end of Moore’s Law to the dominance of the HEN (Huawei Ericsson Nokia) as wireless network equipment supplier, to the 5G standard itself exploding into a Swiss Knife of alternative scenarios to the point it begins to look like an “as a Service” application. The challenge for the modem designers in 5G becomes to pick just the right amount of technology from the highly precise embedded space and the flexible and portable cloud software space and mix them together in just the right manner. This session outlines the pressures faced by today’s modem developer and deduce the challenges to be faced in the development of a successful modem SoC in the 5G era.
