AT&T promised it would start rolling out what it claims will be the first true mobile 5G service before the end of the year, and it has just announced the first three cities in line to receive it.
The company says that the commercial rollout follows multi-city trials …
The term ‘5G‘ is a somewhat ill-defined one at present, with different carriers using the term to refer to different speeds, but AT&T is keen to stress that its own service will be based on 3GPP standards.
3GPP is an international body comprising a range of telecoms associations, and was originally created to agree standards for 3G services.
The way we are implementing 5G in the initial deployments will also seamlessly integrate with current LTE technologies using the non-standalone configuration outlined in 3GPP release 15. The equipment we are deploying today on our LTE network will allow us to easily migrate to 5G.
However, AT&T admits that it won’t be able to guarantee the ‘multi-gigabit’ part of its headline.
In particular, the mmWave spectrum it says it will use for the launch has very limited range – hence the need for a migration path from existing LTE infrastructure.
When 5G support will come to iPhones and iPads is another big question. Apple has been testing the technology, and has made a number of 5G-related patent applications, but doesn’t generally rush into new data standards. As we discussed last time, the company was later than its rivals to support first 3G and then LTE, so we can probably expect it to take its time over 5G also.
The Trump administration briefly touted the idea of a nationalized 5G network, but this was strongly opposed by the FCC and the idea doesn’t seem to have been mentioned since.
