Research and Markets (http://www.researchandmarkets.com/research/h2vb8g/signals_ahead) has announced the addition of the "Signals Ahead: Chips and Salsa XVIII - The Cat 4 is out of the bag" report to their offering.
This report is our eighteenth Chips and Salsa report since 2004 with each of these reports covering various aspects of the wireless IC market. We've done company profiles and emerging trends on various market segments, written about the RF front-end and the many challenges and opportunities associated with LTE and band fragmentation. We've also done more than our fair share of performance benchmarking, including UMTS (call reliability), HSDPA, HSPA+, Mobile WiMA X, A-GNSS, and LTE, including over-the-air (OTA) testing of leading smartphones. This report marks the tenth time that we have collaborated with Spirent Communications in the benchmark studies. As it has done in the past, Spirent provided us with its CS8 test system and engineering support in order to obtain highly objective results.
In the most recent round of chipset testing, we tested solutions from six different chipset suppliers. All of these chipsets had Category 4 (Cat 4) capabilities, meaning that they could support a theoretical peak data rate of -150 Mbps in a 20 MHz LTE FDD channel - the Cat 4 is out of the bag. Five of these solutions came directly from the chipset suppliers while we purchased the HiSilicon-based platform on the open market. This study does not include several chipset suppliers, but to the best of our knowledge very few of them are currently shipping a Cat 4 chipset into a commercially-available mobile device. We look forward to including these chipsets in future testing, including our LTE TDD and LTE Advanced Carrier Aggregation benchmark tests that we are planning to kick off in the very near future.
We subjected the chipsets to 29 different test scenarios that combined a mix of fading profiles (EPA5, EVA5, ETU70 and ETU300, plus Static channel conditions) and transmission modes (Open Loop MIMO and Closed Loop MIMO). We also incorporated different MIMO correlation factors (low, medium, and high), and six different SINR values for each of the four fading profiles.
Based on our highly-objective evaluation criteria, Samsung's pre-commercial chipset was the top- performing chipset, based on its average throughput in each of the tests and based on its individual finishing place in each of the tests. We explain our ranking criteria in more detail later in this report. Samsung (19) also had the most first place finishes, followed by MediaTek (4), Qualcomm (3), Intel (2), and Ericsson (1).
We also ranked the chipsets for each grouping of ITU channel models. Based only on the ranking of average throughputs, the winning chipsets in each grouping of tests were as follows: Static (MediaTek - pre-commercial), High SINR with varying MIMO correlation factors (Intel - commercial hardware), EPA5 (Samsung - pre-commercial), EVA5 (Samsung - pre-commercial), ETU70 (Samsung - pre-commercial) and ETU300 (Samsung - pre-commercial). All this and more in this issue of Signals Ahead.

1.0 Executive Summary
3.0 The Results - Sliced and diced several different ways
4.0 Results and Analysis by Test Grouping
5.0 Deep Dive Analysis

Digital Transformation is the ultimate goal of cloud computing and related initiatives. The phrase is certainly not a precise one, and as subject to hand-waving and distortion as any high-falutin' terminology in the world of information technology. Yet it is an excellent choice of words to describe what enterprise IT—and by extension, organizations in general—should be working to achieve. Digital Transformation means: handling all the data types being found and created in the organizat...

Container technology is sending shock waves through the world of cloud computing. Heralded as the 'next big thing,' containers provide software owners a consistent way to package their software and dependencies while infrastructure operators benefit from a standard way to deploy and run them. Containers present new challenges for tracking usage due to their dynamic nature. They can also be deployed to bare metal, virtual machines and various cloud platforms. How do software owners track the usag...
