Everything in Timeline
- GSM goes liveThe first GSM networks opened in 1991 and set the pattern of a standard defined before deployment rather than after it.
- LTE, and the end of the circuitLTE moved cellular to an all-IP core, which is the change that made voice a service on the data network rather than the other way round.
- Wi-Fi 6 was a rename, not a releaseThe Wi-Fi Alliance applied generation numbers retroactively in 2018, an admission that the lettering had failed as communication.
- Wi-Fi 7 and the width problemWi-Fi 7's widest channels need spectrum that not every regulator has released, so the same product performs differently by country.
