Pros: No one knows what 4G is anyway, not by the ITU-r standards. The government could deploy a bowl of spaghetti and call it 4G internet and people would believe it…just like they believed VZW, ATT etc.
Cons: The Government doesn’t know what 4G is. If they did, the FTC would be contesting VZW and ATTs claims to be 4G carriers. You could sell the government a bowl of spaghetti and tell them it is 4G internet and they would very likely buy it….with your money.
