Gigabit LTE, as demonstrated by Ericsson and Huawei, sounds impressive (see separate item), but it is thrown into the shade by more blue-sky tests reported by Nokia Bell Labs and Mitsubishi, using putative 5G techniques to achieve 30Gbps and 20Gbps respectively. One of the first announcements from Bell Labs under its latest ownership was the demo of a system which not only reached the 30Gbps peak speed, but could also support a million simultaneous connections in the same cell. The peak rates were achieved by aggregrating a range of mobile and fixed technologies into one “ultra-capacity” stream, and a combination of techniques were employed to enable massive density and very low latency – the qualities required for some of the…
