The new highly hyped tech advance known as 5G will boost the capabilities of computer-to-computer communications. Which for consumers means . . . not that much, actually. Martin Reisslein, Fulton Schools professor of electrical engineering and an expert in communications networks, says 5G is an enhancement for machines that interact with machines and with humans using machines. The 5G improvement involves reducing “latencies” — the time it takes between communication initiation and response. It will make a difference only to those for whom “milliseconds matter,” Reisslein says. So that may be an advantage for players of fast-paced computer games, but not for most other users.
