Stephane Teral, research director for mobile said “the 4G experience is still far from consistent and is falling short of expectations.
She said that the debate over 5G is being accompanied by “fanfare, hype and confusion, but little substance about what it is exactly and what it is not. For now the mindset is still locked into mobile broadband as we know it with LTE, so it’s good that the ITU has just stepped in to define 5G in its brand new IMT-2020”.
She said Ericsson, Huawei and Nokia are the top LTE (4G) equipment manufacturers. And commercial voice over LTE (VoLTE) will ramp in volume this year and next year.
And although vendors are talking about 4G network functions virtualisation migration, Teral said that won’t happen very fast because most LTE networks are new, and mobile operators simply aren’t ready to migrate.
