Most engineering firms are deep in one discipline. Faststream is organised around the fact that a connected product is never one discipline, and that the difficulty concentrates at the boundaries — between the chip and the board, the board and the firmware, the firmware and the radio, the radio and the cloud.
That is why the company describes itself through System Integration rather than as an engineering services provider. The distinction is about accountability: supplying specialists into a customer's plan is a different business from owning an outcome that spans disciplines.
The portfolio reflects the same shape. Licensable IP cores because silicon customers need blocks. Radio subsystems because the digital front end is where amplifier economics are decided. Gateways, trackers and vision systems because connected products need hardware that exists. Frameworks because a fleet needs managing after it ships.
