Sprint, NSN showcase 1.3Gbps over TDD-LTE
Being in the Silicon Valley, often to check out the latest innovations from our North America research and innovation teams, is one of my favorite parts of the job. This time was even more exciting as we joined Sprint to showcase 1.3Gbps throughput over TDD LTE. The event was organized as part of Sprint’s contract announcement to NSN for the supply of TDD LTE technology and associated deployment and support services, a major booster for our LTE market share in North America.
The showcase was hosted in Sprint’s lab near San Francisco, very close to our own Innovation centre in Mountain View. We put our commercial Flexi Multiradio 10 Base station platform to work on 60MHz of Sprint’s 2.5GHz spectrum band to deliver 1.3Gbps downlink throughput in a single sector over TDD LTE. We leveraged TDD LTE Advanced features to achieve this breakthrough. With this demo, Sprint became the first North American operator to achieve such a speed record on commercial gear and TDD LTE spectrum, almost ten times the speed of current LTE networks.
Sprint CTO, Steven Bye was very excited about this achievement and it was particularly rewarding to see the entire Sprint team highly engaged in our TDD LTE speed demo. They spent most of their time with our showcase despite a lineup of many other cool demonstrations related to devices and applications at the event – nice compliment for networks! Check out this video from the event, the buzz is electric.
If I rewind the thoughts of the research community to pre-2000 years, we thought technology would evolve to enable networks to deliver 100Mbps speeds by 2010 and 1Gbps by 2020. But here we are in 2013, fast forwarding technology by a decade, by already delivering 1.3Gbps speeds on commercial hardware. I am awed by our progress and equally amazed by the hunger for more and more data and faster and faster networks.
Rewinding back to about five years ago, when the world was deploying 3G and I was busy planning LTE and LTE-Advanced 3GPP specifications, we knew that success of LTE depended on opening up large amounts of usable spectrum, which could theoretically allow 1Gbps mobile broadband data throughput. And that also meant driving the TDD LTE technology and ecosystem along with FDD LTE given the goldmine of available spectrum in TD bands.
Turning our LTE vision into reality has been an exciting journey. With the conscientious efforts of our teams in driving global adoption of TD-LTE, many governments have now allocated large amounts of spectrum TD-LTE bands like band 40 (2.3GHz) and band 41 (2.6GHz). Personally, it has also been very humbling to outdo ourselves by showing a series of world records for more than 1Gbps throughput. With my teams now working on the communication networks of the next decade, I have no doubt we will surprise ourselves, again!
