I'll wait for 5G
"The plan is based on 40 million predicted connections within the next five years, which is a hell of a lot even if one is selling wholesale."
Over recent years we've seen the launching of several very expensive technological upgrades that have failed to take the world by storm. Vista, Blue-Ray and the PS3 are three good examples. By offering only a marginal improvement in quality (in the mind of the consumer) at a significant extra cost, most of the market simply said "thanks, but no thanks".
Will 4G be a similar flop? Harbinger is banking on a significant change in the way the market currently works. At the moment, most people don't have a data plan with any mobile device, and there are a lot of consumers who will never want to do more than check their emails, Facebook and Twitter accounts. For this 3.5G is adequate, especially as most smartphones come with wifi. 4G will only become a standard if the phone manufacturers and mobile networks decide to make it standard... and that will almost certainly mean having to subsidise both handsets and data costs for the first few years.
Considering the sleight-of-hand tactic being used by Harbinger, the big networks may just decide to refuse to stump up the extra cost, drive the Harbinger out of business and then buy up the infrastructure at a fraction of the cost it took to put it in place.
