I agree. Delivering 100Mbps as an avg performance for many dozens on one site is not likely in the foreseeable future. Advanced LTE and WiMAX 2.0 can do it but will there be enough spectrum for most carriers? Backhaul is a challenge too.
Requiring 100Mbps for 4G is not very realistic for many many a year. 4G may as well be 10Mbps to distinguish from previous 3G - and yes, it's OK to label HSPA+ as 4G if it looks like a duck.
