With 6G deployment already being projected, when I don't even know anybody with a 5G handset, it also seems like a make-work technology.
Deployment of a new wireless technology throughout a national wireless carrier, let alone all carriers in a country the size of the US, or in the world, is such a huge undertaking in terms of environmental resources, that it seems almost irresponsible unless there is a significant improvement.
2G was a quantum leap over 1G analog networks. In 2G networks like GSM, the digital communications stack was so tightly integrated, and as optimized as a 1990s video game, that even everyday layman users knew stories like "I could send an emergency SMS from the middle of nowhere even when there was no signal". It seems like that kind of robustness is missing the more abstract and higher-level these wireless generations go.
- Very good quality cameras front and back, including IR, dot projector and flash
- Analog audio I/O
- GPS receiver
- 3D accelerometer and gyroscope
- Magnetometer
- Ambient light level and color temperature
- Ambient temperature, air pressure, hygrometer
- Radiation detector
- Wasn't there some research into a user-facing radar that could detect gestures?
- GPIO and SDR
