I worked on the kernel parts of the pre smart phones.

When GSM was invented, there was real doubt that it might not be possible to meet the very specific timing needs on the hardware that was available at the time.

I remember when we had to integrate Bluetooth into our 16 bit, 8Mhz Infineon E-gold platform. We had ~20 people working on it for 2 years.
