Nokia Siemens Networks wasn't fibbing when it said it would re-focus its efforts on mobile broadband. It's just announced a 'six pipe' radio head upgrade for time division LTE (TD-LTE) base stations that can boost capacity by 80 percent and coverage by 40 percent compared to a traditional three-sector site. Alternatively, the same replacement can be used to reduce a station's running costs, by allowing it to cover three sectors using a single radio head. As far as we're concerned, anything that recalls OK Computer is a good thing, but if it speeds up carriers' shift to LTE then it's even better. Meanwhile, for those who still want to invest in CDMA, Nokia Siemens is pushing it's 1X Advanced technology, which also promises big improvements in voice and data capacity as well as energy efficiency. Read on for more technical details in a PR double-shot.
