Of 528 organizations globally that have deployed, or are deploying private 4G or 5G networks, either to test them or for commercial deployment, about 70 percent to 75 percent use 4G (Long Term Evolution) rather than 5G, according to the Global Mobile Suppliers Association.
Some 24 percent to 29 percent of those trials or deployments use 5G, GSA reports. GSA has partial or some data on a total of 626 instances (including planned tests or deployments). Some 50 infrastructure suppliers and 71 mobile operators are involved in the tests or deployments.
Automotive companies account for over 18.5% of the 108 identified manufacturing companies holding suitable licences or involved in known pilots or deployments.
Though 5G has performance advantages over 4G, it seems clear that 4G private networks are deemed suitable for the purposes enterprises have in mind.
For example, 5G offers 10 times the speed of 4G. Where 4G tops out at 150 Mbps, 5G can support 1 Gbps to 10 Gbps data throughput. 5G also supports up to two orders of magnitude more devices per radio site, compared to 4G.
At least in principle, private 5G networks have availability of 99.999 percent to 99.9999 percent. In principle, however, 4G should match the “five nines” standard.
5G provides an order of magnitude improvement in latency, compared to 4G. Where 5G is capable of one millisecond round-trip latency, 4G is rated at about 10 milliseconds.
Also, 5G has been engineered for 90 percent less power consumption than 4G, making 10-year battery life feasible for some devices.
It would appear none of those advantages are mission critical for existing mobile private network users.
