Modems need to take very faint, very noisy analog input that often bounces and overlaps with itself and other signals, digitize that and interpret the results. It has to do that quickly, reliably, without burning through batteries and without costing $100/chip. It also has to not step on patents owned by Qualcomm.I don’t understand why building a modem is so challenging. I wonder if it is more of a patent legal obstacle course rather than a technical hurdle.
Easy Peezy! 🤣
