Research and Markets: Signals Ahead for LTE: By the Light of the Silvery Moon

Research and Markets (http://www.researchandmarkets.com/research/j7hsc9/signals_ahead_by) has announced the addition of the "Signals Ahead: By the Light of the Silvery Moon" report to their offering.

When operators first launched LTE starting back in late 2009 they used a standard 2x2 MIMO implementation, meaning two transmit / receive antennas at the cell site and two receive antennas in the mobile devices. And until last year they also relied on Cat 3 (Category 3) devices which under certain circumstances became the bottleneck that limited downlink data rates in a 2x20 MHz network. The resultant data rates were still very impressive and dramatically higher than they were with DC-HSDPA - thanks, in large part to the wider channel bandwidths - but in hindsight they could have been even better.

Thanks to the technology advancements that the industry has made for infrastructure and devices / chipsets and the initiatives taken by some forward-thinking operators, LTE is undergoing another round of performance improvements. It is also providing many of these improvements under the auspices of the Release 8 standard. One noteworthy example, which also happens to be the subject of this Signals Ahead report, is the introduction of 4x2 antenna schemes.

KEY OBSERVATIONS INCLUDE THE FOLLOWING:

  • The benefits of 2x20 MHz LTE, a Category 4 smartphone, and 4x2 CL- MIMO cannot be ignored
  • Peak data rate of 143.8 Mbps in the downlink (per TTI) and 46.93 Mbps in the uplink (per second)
  • The median MAC (Media Access Control) Layer downlink throughput was 36.42 Mbps and the median MAC Layer uplink throughput was 28.15 Mbps - both values include 2x2 OL-MIMO results
  • The downlink throughput exceeded 10 Mbps for nearly 95% of the time and the uplink throughput exceeded 10 Mbps for 87% of the time - both values include 2x2 OL-MIMO results
  • The clincher for bullish views on a 4x2 cell site configuration appears after we filter the 4x2 and 2x2 results.
  • Substantially higher uplink user data rates, in particular closer to the cell edge
  • Far more efficient scheduling of uplink network resources, again when the mobile device was closer to the edge of cell
  • A clear indication of improved battery life throughout a large portion of the cell
  • Meaningful improvements in downlink data rates near the edge of the cell
  • Consistent with our earlier study, 4x2 CL-MIMO delivers strong gains versus transmit diversity for a wide range of network conditions - perhaps even a greater range than we previously observed with 2x2 OL-MIMO.

The major cloud platforms defy a simple, side-by-side analysis. Each of the major IaaS public-cloud platforms offers their own unique strengths and functionality. Options for on-site private cloud are diverse as well, and must be designed and deployed while taking existing legacy architecture and infrastructure into account. Then the reality is that most enterprises are embarking on a hybrid cloud strategy and programs. In this Power Panel at 15th Cloud Expo (http://www.CloudComputingExpo.com...
The move in recent years to cloud computing services and architectures has added significant pace to the application development and deployment environment. When enterprise IT can spin up large computing instances in just minutes, developers can also design and deploy in small time frames that were unimaginable a few years ago. The consequent move toward lean, agile, and fast development leads to the need for the development and operations sides to work very closely together. Thus, DevOps become...
