From the article: "Modem chips are trickier to make than processing chips because they must work seamlessly with 5G wireless networks, as well as the 2G, 3G and 4G networks used in countries around the world, each with its own technological quirks. Apple microprocessors run software programs designed solely for its iPhones and laptops."
Also: "[Apple's modem] chips were essentially three years behind Qualcomm’s best modem chip. Using them threatened to make iPhone wireless speeds slower than its competitors."
I wonder what some of the regional quirks are, instances where the implementation strays from the standard, but if you don’t do it in quirks mode, you can’t connect to the cellular connection or calls will not go through etc.
A sort of woops, non-strict YAML moment, but in telecommunications.
