We've been having it!

For a number of months now, first LTE towers went live about middle last year.
The problem is not the network technology but on what spectrum we can deploy it. All the networks have the same spectrum but the bigger the network (i.e. the more users on the network), the less spectrum is available to deploy LTE. Neither Vodacom nor MTN can really refarm the amount of spectrum needed for a decent LTE service. Deploying LTE on current 900, 1800 or even 2100 allocations will result in a crippled LTE service.
What everyone needs is new spectrum for LTE so additional capacity can be built. Thus the continuous requests to ICASA for 2.6 spectrum. First price would be to get the digital dividend sorted so LTE can be deployed on 800.
But then, I also believe in the Easter Bunny.
As I've stated many times before, deploying newer technolgies is not about outright speed but rather all about getting more capacity from a single tower so more people can get a decent speed.
