Behind the VoLTE Curtai: Analysis of Four Smartphones / VoLTE Clients Using T-Mobile's LTE network in Southern California - Apple, LG, Samsung & Sony
M2 - Thu Jan 22, 8:42AM CST
Research and Markets (http://www.researchandmarkets.com/research/pkbm9t/behind_the_volte) has announced the addition of the "Behind the VoLTE Curtain, Part 2" report to their offering. KEY HIGHLIGHTS FROM THIS STUDY This report presents the results of an analysis of four smartphones / VoLTE clients using T-Mobile's LTE network in Southern California. The smartphone tested are the Apple iPhone, the LG G Flex, the Samsung Galaxy Light, and the Sony Xperia Z3. Authors' view: We did this study in collaboration with Spirent Communications, who provided us with its test equipment and engineering support to collect much of the data. In addition to gaining some insight into how VoLTE compares with HD-Voice on a 3G network and how the 23.85 kbps voice codec compares with the more widely used 12.65 kbps voice codec, we also identified the performance differences between the four smartphones / VoLTE clients that we tested. Although we didn't identify any meaningful differences when it came to the perceived voice quality (MOS) we did observe differences when it came to the impact on the current drain and estimated battery life. For example, only one smartphone achieved a longer battery life with VoLTE than with 3G CS voice. Two smartphones came relatively close to achieving this important threshold and one smartphone had a significant performance disadvantage with VoLTE compared with 3G CS voice. We were only able to obtain chipset diagnostic information for two of the smartphones so we also relied on results taken last summer when we tested AT&T's VoLTE implementation. In this category the two smartphones preformed largely on par with each other - not surprising given that they both use the Qualcomm chipset. Both smartphones also had much better KPIs than what we observed last summer. Various factors could explain this phenomenon, but in any event the trend is positive for VoLTE. Lastly, we included FaceTime and Viber, along with Skype, to see how the OTT voice applications compared with VoLTE. Consistent with our results from last summer, we observed that these applications can deliver a great voice call - in some cases outperforming VoLTE. However, they do quite poorly with network loading while the cost impact in terms of the shortened battery life and the higher network resource requirements cannot be ignored.

Business Wire - Mon Aug 18, 8:32AM CDT
Spirent Communications, the leader in testing networks, services and devices, announced today it is collaborating with Signals Research Group (SRG) to conduct a two-part study that evaluates the VoLTE User Experience by analyzing VoLTE voice quality, call performance and battery performance. The recently completed part one of this benchmark study compared VoLTE service to 3G Circuit Switched Voice and Over The Top (OTT) Skype Voice Service on the live network of a major US operator. The study revealed VoLTE is worth the wait and successfully delivers on the promise of superior Quality of Experience (QoE) and efficient use of network resources.
Signals Ahead: AT&T's VoLTE Service Performance and Analysis with Alcatel-Lucent's Radio Access Network, Core Network, and IMS Infrastructure
M2 - Thu Aug 14, 8:04AM CDT
Research and Markets (http://www.researchandmarkets.com/research/sc82sn/signals_ahead) has announced the addition of the "Signals Ahead: VoLTE Performance and Analysis" report to their offering. We conducted a network benchmark study of AT&T's VoLTE service (Alcatel-Lucent provides the Radio Access Network, Core Network, and IMS infrastructure) in Minneapolis-St. Paul in collaboration with Spirent Communications who provided us with its test equipment and engineering support. KEY OBSERVATIONS INCLUDE THE FOLLOWING: - VoLTE is pretty much everything that we hoped it would be. - The call quality (MOS), based on the POLQA algorithm, greatly exceeded that of 3G CS Voice and it was measurably higher Skype (over Wi-Fi and LTE). With background applications running on the same phone and transferring data with the network the VoLTE results were considerably better than Skype - the latter seemingly showed no impact while the latter frequently failed to deliver the voice packets in many cases. - Relative to 3G CS voice, VoLTE's big advantage was the call setup time with a CSFB call taking nearly twice as long to establish as a VoLTE call. - VoLTE required substantially fewer network resources (DL/UL resource blocks, scheduled TTIs, PDCCH scheduling grants) than Skype and presumably other OTT voice applications. We attribute this advantage to QCI=1 features, such as RoHC, TTI bundling, and DTX/DRX, which are either not supported by an OTT application or which are supported less efficiently. Once SPS and short DRX are launched the differences should be even more substantial. - The network savings also translates into VoLTE call requiring less current drain and power consumption than a Skype call, meaning a longer batter life. Presently 3G CS voice has a slight advantage over VoLTE in this category. - Continued improvements in LTE network coverage will give VoLTE an even greater advantage in the future and it will reduce the number of eSRVCC handovers to the 3G CS network. Key Topics Covered: 1.0 Executive Summary 2.0 Key Observations and Conclusions 3.0 Voice Call Quality Analysis 4.0 Network Resource Analysis 5.0 Call Reliability, Call Setup Time and IRAT Handover Analysis 6.0 Battery Life, Current Drain and Power Consumption Analysis 7.0 Test Methodology 8.0 Final Thoughts 9.0 Appendix For more information visit http://www.researchandmarkets.com/research/sc...nals_ahead

Global Chips and Salsa XVIII Report 2014 - The Cat 4 is Out of the Bag
M2 - Wed Aug 06, 3:51AM CDT
Research and Markets (http://www.researchandmarkets.com/research/4nr4xk/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. Key Topics Covered: 1.0 Executive Summary 2.0 Introduction 3.0 The Results - Sliced and diced several different ways 4.0 Results and Analysis by Test Grouping 5.0 Deep Dive Analysis 6.0 Test Methodology 7.0 Final Thoughts Companies Mentioned - Ericsson - HiSilicon Intel - MediaTek - Qualcomm - Samsung For more information visit http://www.researchandmarkets.com/research/4n...nals_ahead

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).
