TO THE EDITOR:
Regarding "Safer roads outweigh expanded Wi-Fi," Nov. 4: Moving bandwidth from dedicated short-range communications to Wi-Fi is a poor idea. Clearly, there is a tremendous expansion in the world of driver-assistance and traffic management electronics. Whether we think that is a good idea or not, it is underway, and we are going to have to live with it. In anything to do with electronics, bandwidth is important.
That said, there is some rhetoric on both sides that needs to be vetted. Example: "A Rand Corp. study in 2018 cited that opening the 5.9 GHz band to expanded Wi-Fi use would add between $60 billion and $106 billion to U.S. gross domestic product annually." I doubt it, at least if costs such as productivity lost and injuries incurred by the indiscriminate use of cellphones and other attendant costs are factored in. Another example: "Putting DSRC to work tomorrow would help us reduce road deaths by more than half." I doubt that, too. There are things that can be done — bringing roads up to some minimum standard, as an example — but none of them by themselves will do what is claimed for DSRC.
Wi-Fi can wait for 5G much easier than DSRC or any other measure that requires coordinated effort by governments.
