Same tools as gig LTE, only more so. At Huawei's November Tokyo event, a large sign about "Two Gigabit Mobile" for Britain intrigued me. Below, some details of a 2 gigabit test run by BT's EE division and Huawei. One gig hadn't yet shipped, so what was this? The booth engineer confirmed two gigabit systems were not yet available, but expects them soon. Using more spectrum and efficiently delivering MIMO in all bands will get close to the two gig target, in 2018 if not 2017.
I explain the technology involved in For non-engineers. How LTE gets to the gigabit: 4x4 MIMO, 4 Band Carrier Aggregation, 256 QAM In a gigabit cell site, phones usually connect at hundreds of megabits. If few are using the cell, individual speeds can approach the gigabit.
Two gigabits could double that speed, but does anyone need that much speed today? Probably not, but the gigabit and two gigabit cells allow serving all customers at much higher speeds than today
