What is the future of LTE?

Question

When WiMax was there everyone was talking about the WiMax, now LTE in future may be 5G. What if 5G comes before LTE takes over the market. Is there a market risk with LTE in this way?

Answer 1

At least in India LTE is not going to be a hit, that seems to be the trend. Number of 4G subscriber for the Airtel is still less then 20K (source http://en.wikipedia.org/wiki/Bharti_Airtel) and there is already a price war started in the data space.
Now coming to the main point if there a market risk with OFDMA then answer is yes, before the critical mass is achieved if any new technology comes then OFDMA can be a old story. But EPC will remain as most of the infrastructure part will be reused whatever technology come.
