At CDNLive EMEA last month, Stefan Stanic of Methods2Business (M2B) presented The Challenge of Designing a First-TIme-Right Wi-Fi HaLow Baseband in Less than Six Months. WI-FI HaLow is a standard for superior IoT connectivity. Links can be up to 1km, with superior connectivity through walls and other obstacles. It is low power, intended for mutl-year battery operation in edge devices. The data rates are "moderate" meaning several Mbps but fast enough to support standard internet connectivity protocols like TCP/IP. M2B has designed a scalable MAC and baseband (BB) platform with an embedded Tensilica core for the MAC firmware. The focus of the presentation was the baseband. Another challenge was that this is new technology, so there are no reference designs, so no existing devices that implement the protocol to use for testing.
