So the only way to make that workable is for every car to in effect be its own cell tower, adding yet more cost & complexity. |
5G won't be restricted to high frequency, which is why they killed off 2g and have already set drop dead dates for 3g.
Also, beam forming technology from wifi will likley be implemented and will improve transfer rates and range.
