Should the 4g and lte be merged? Whilst there might technically be a difference between them I don't think most users realise (or care) and both terms are used interchangeably.
What is LTE?
Though originally marketed as 4G technology, LTE (Long Term Evolution) didn't satisfy the technical requirements that the ITU-R outlined, meaning that many early tariffs sold as 4G weren't actually 4G.
However, due to marketing pressures and the significant advancements that LTE brings to original 3G technologies, the ITU later decided that LTE could be called 4G technology.
