TD-LTE gathers momentum
The next generation of China’s homegrown mobile technology, TD-LTE, is gathering momentum among the vendor community, as a public demonstration of the platform starts up at the World Expo in Shanghai.
Motorola, working with China Mobile, has deployed and is supporting an indoor TD-LTE network for “a couple of thousand” dongles at the Expo, which takes place in Shanghai between May and October this year.
The company said a single TD-LTE USB dongle can stream 24 simultaneous video streams while supporting high speed internet browsing applications, at a total data rate of 20Mbps.
The US vendor also announced that it has completed the Phase I TD-LTE field trials with China’s Ministry of Industry and Information Technology (MIIT), demonstrating key functionality, performance and mobility test cases in a multi-sector, multi-site environment.
During the trial, Motorola demonstrated a downlink throughput of up to 80Mbps, with TD-LTE trial sites overlaid on existing 2G/3G sites.
Motorola and the MIIT are now ready to begin Phase II TD-LTE field trials with an increased focus on applications and quality of service (QoS) in Shunyi, Beijing.
At the same time, handset vendor Samsung and Nokia Siemens Networks (NSN) have announced what they claim is the “world’s first end-to-end TD-LTE data call”. The data call was made using a prototype end user USB dongle from Samsung and infrastructure from NSN, namely the Flexi Multiradio Base Station and the company’s core network solution, including the Flexi NS (Network Server) and the Flexi NG (Network Gateway) – all using LTE software compliant with the 3GPP March 09 baseline specifications.The trial was conducted at NSN’s R&D Center in Hangzhou, China.

China Mobile announced to show live demonstrations at NGMN Industry Conference in Shanghai, 2-4 June. Commercial product release should be on the 2 June
With all my respect to the TD-LTE technology, but the 80Mbps that they announce is somtimes is the total Base station download throughput or the throughput per one sector. If multiple users share the same Base station (lets say 20 at a time) then the average downloaded rate is = 80/20=4Mbps !
So when you announce the download rate, you have to mention is it per Base station or per one sector or per frequency carrier . Many thanks
The 80Mbps is based on one sector……
Unfortunately, HSPA biased comments need to be also raesonable. When you are talking about the sector throughput on LTE, you need also to compare it with sector throughput on HSPA. Adding to that the fact that only 4% of the subscribers that are actually near the center of the cell will get benefit from the claimed high speed with HSPA, compared with 60% enjoying super high speed on LTE, you will findout that this comment is not realistic and far from being credible and reasonable.
