Last week we focused on how the R&D lines between 4G and 5G are blurred – many technologies which are likely to end up in the 5G standards are already being trialled and even deployed as part of the evolution of LTE, creating a continuum which may save operators from another big bang upgrade. And the announcements just keep coming, only stimulated by the start of the World Radio Conference 2015 this week, with hopes for some pointers on 5G spectrum; and by the kick-off of the 3GPP standardization process.
