To hear the major mobile carriers talk about it, 5G is here. They’ve deployed it, it works, and it’s ready to start changing the world just about right away, with ultra-fast connectivity, low latency and a dramatically improved ability to handle huge numbers of different connections at once.
Eventually, that will all be true – but, according to experts in the field, it isn’t yet, and most of it won’t take place within the coming calendar year. The 3GPP standards that will underpin all new-radio 5G technology are still not yet finalized, although that is expected to happen in early 2020, which means the much-touted 5G deployments in the U.S. are based partially on pre-standard technology.
