Embedded development but specifically low-powered embedded development. Not everything is wifi and cell network, sometimes you have devices that wake up, broadcast a signal over LoRa or Zigbee and return to sleep. Specialized batteries can last 10+ years. You see some of this stuff in smart lighting remotes and sensors. However much of this was done in the interest of as few cpu cycles as possible rather than raw speed. |
