Research and Markets: Operators will Turn to LTE TDD for a Much-Needed Capacity Layer

Research and Markets (http://www.researchandmarkets.com/research/px4p22/signals_ahead) has announced the addition of the "Operators will turn to LTE TDD for a much-needed capacity layer" report to their offering.

This report is the first exhaustive [and exhausting] independent analysis of LTE TDD for public consumption. Over a four day period in late August, we conducted a drive test of Softbank's LTE TDD and LTE FDD networks in the greater Tokyo region. In addition to comparing the two LTE duplex schemes while doing lengthy downlink and uplink throughput tests in a mobile environment - we transferred 124.2 GB just on the LTE TDD network during these tests - we also looked at the performance of the two duplex schemes with more typical applications.

This effort would not have been possible without the support of Accuver, who provided us with access to its XCAL data collection tool and its XCAP post-processing software. We have used the solution numerous times over the last several years so we are very accustomed to using it, although we do stumble upon new capabilities and features each time we use it. In our most recent benchmark studies, specifically LTE TDD in Tokyo and LTE Advanced Carrier Aggregation in Seoul, the solution's ability to support recently introduced technology features, including Category 4 chip sets and Carrier Aggregation, proved to be invaluable.

This drive test campaign was entirely self-sponsored although we did receive logistical support in the form of test SIMs, a high bandwidth server, and mobile devices. SRG assumes full responsibility for the analysis and commentary included in this report.

In her session at Big Data Expo®, Hannah Smalltree, Director at Treasure Data, discussed how IoT, Big D...
Connected devices and the Internet of Things are getting significant momentum in 2014. In his session at Internet of @ThingsExpo, Jim Hunter, Chief Scientist & Technology Evangelist at Greenwave Systems, examined three key elements that together will drive mass adoption of the IoT before the end of 2015. The first element is the recent advent of robust open source protocols (like AllJoyn and WebRTC) that facilitate M2M communication. The second is broad availability of flexible, cost-effective ...

There is no question that businesses successful in adopting a DevOps mindset have seen departmental culture change, ...
