Azimuth Announces VoLTE Support for Industry Leading Analytics and Automation Solution
May 20 14
Azimuth Systems, Inc. announced the addition of unique VoLTE support to their integrated analytics and automation toolset, DNA and DAC. VoLTE is one of the most challenging milestones in the ubiquitous adoption of LTE whereby voice and video can be sent over LTE's packet-based network while leveraging its substantial QoS and policy framework capabilities. VoLTE will no longer require bandwidth to be separately allocated for circuit switched traffic; it will instead allow operators to share capacity for voice, video and data. VoLTE is thus expected to be a key element in operators' LTE-based plans to offer high quality of service to consumers and monetize their investments with differentiated offerings. Azimuth's DAC and DNA solution for VoLTE delivers detailed per call as well as aggregated analytics and reporting for VoLTE deployments. Seamless integration of the DAC and DNA products ensures that Azimuth's solution for VoLTE provides rapid and effective test and analysis of VoLTE performance. This is essential in both deployment and post-deployment phases of VoLTE, to meet the quality expectations users have of a 4G service. Azimuth DAC and DNA toolset is Azimuth's platform for advanced VoLTE support. Device Automation & Control (DAC) enables unattended execution of user experience testing and logging for smartphones and other mobile devices. Device-Network Analytics (DNA) provides KPIs and analytics that enable device benchmarking and profiling, linking subscriber perceived performance to underlying device-network interaction and root cause analysis for both voice and video performance Azimuth DAC and DNA for VoLTE is unique in that it: Is the ONLY solution in the industry that intelligently ties the VoLTE SIP, RTP layer performance with the underlying LTE device-network interaction Unlike other solutions that show events across multiple layers as individual/disjointed events, DNA leverages advanced algorithms to synchronize events from different layers to provide a unified view that connects user performance to the underlying device-network interaction. Performance is typically reported for a statistically significant number of samples, however, common statistical analysis tools could underestimate the impact of outliers (VoLTE, unlike data, is very unforgiving). Integration of DAC automation allows for immensely valuable control, logging and analytics at a very granular level.
Azimuth Systems, Inc. Plans to Deploy LTE, LTE-Advanced and Voice over LTE (VoLTE) in 2014
Feb 17 14
Azimuth Systems, Inc. announced that it plans to deploy LTE, LTE-Advanced and Voice over LTE (VoLTE) in 2014. The increasingly complex interactions between networks, devices and applications call for an expanded scope of testing at lower incremental cost. Azimuth will be exhibiting solutions designed in collaboration with the industry's operators and manufacturers to specifically improve testing of new network and device features such as Carrier Aggregation and VoLTE, using new methods such as Multi-Link Scenario Application, Device-Network Analytics and Intelligent-Over-The-Air. LTE-Advanced: Effective testing of Carrier Aggregation (CA) and Heterogeneous Networks (HetNet) in the lab requires large testbeds to model many disparate, simultaneous radio frequency links representing the full scope of real-world propagation environments. Creating the corresponding test cases in turn requires more time and more engineering resources than ever before. Azimuth is introducing the Multi-Link Scenario Application (MSA) to allow test engineers to quickly advance from test case definition to automated test setup and execution on Azimuth ACE channel emulators. MSA's benefits include: Aligned to ecosystem requirements--preselected test scenarios were chosen in collaboration with leading operators, infrastructure and device vendors; Dramatically reduces test development--select a Coverage Map and Mobility Path to define the CA test case; MSA then executes algorithms to compute frequency-adjusted link characteristics which are available for immediate playback; Dynamic Uplink--true bi-directional capabilities to ensure that the device's uplink closely emulates real-world power control and signaling behaviors; and Scalable and extensible--initial scenarios focus on CA, and the framework will easily support plug-ins for HetNet and other emerging multi-link applications. VoLTE: with operators set to launch VoLTE service commercially later this year, industry attention turns to assuring the quality of experience, given users' low tolerance for poor performance when it comes to the most essential aspect of mobile communications. Azimuth's focus is on testing at the device level, with user experience automation and device-network analytics software intended to benchmark performance of multiple devices, and facilitate identification and resolution of root causes of performance issues. Azimuth's VoLTE solution: Automates the essential user experience applications on smartphones, including voice, messaging, data and video Enables synchronized testing and diagnostic logging of multiple devices; Analyzes, visualizes and correlates metrics from user experience to device performance and network conditions, including access, connectivity, mobility and PHY/MAC; Addresses critical aspects of VoLTE including call registration and setup, call presence and quality, further broken down into mobile originating, mobile terminating, audio LTE and video LTE calls; Parses and reports key VoLTE parameters and KPIs related to TTI bundling, DRX and dedicated bearers for voice and video calls;Provides rich yet easy-to-understand reports for comparison of multiple devices, identification of issues and root causes, and rapid decision-making; Intelligent Over-The-Air: Azimuth has literally cut the cord in mobile performance lab testing. Traditionally, the device under test (DUT) is opened up and the RF port is connected to test equipment using a cable. This widely accepted method has delivered useful results but has always ignored the performance impact of a critical component of the device: the antenna. Over-the-air (OTA) testing places the DUT in a shielded chamber for a precisely controlled environment, and radiates the network information through the antenna, exercising the device in its native state. Azimuth's Intelligent Over-The-Air (iOTA) further augments OTA testing, by going beyond antenna measurements to benchmark multiple devices and predict performance in market; replaying field RF conditions captured during drive testing for more relevant scenarios; automating essential user applications such as messaging, browsing and video streaming; and facilitating root cause analysis rather than just a pass/fail measurement. iOTA's advantages include: Only supplier to offer both the reverberation chamber and channel emulator directly, with attendant benefits of seamless integration; Switching between antenna characterization (TIS/TRP) and performance (throughput testing) without days of effort to reconfigure the system; The first MIMO OTA performance test platform mandated by a U.S. Tier-1 operator to its device ecosystem. As mobile networks become more complex--with the deployment of carrier aggregation, HetNet and VoLTE--so are the devices connecting to them. Both the network environment and device utilization need to be represented as precisely as possible to deliver meaningful, repeatable test results. By enhancing prediction of performance in subscriber scenarios under real-world conditions, Azimuth's test solutions enable more efficient development, qualification, marketing and troubleshooting of mobile devices. Device manufacturers and component suppliers can validate or revise designs further upstream in the development process. Operators can ensure that devices perform as expected on their networks prior to launch, troubleshoot issues found once devices are in market, or identify root causes for returns.
Azimuth Introduces Intelligent Over-The-Air (iOTA) Platform, Opening Up The Next Frontier for Mobile Device Lab Testing
Dec 5 13
Azimuth Systems, Inc. announced the evolution of its over-the-air test platform, developed to measure and analyze performance of mobile devices in their native states, under real-world conditions. Intelligent Over-The-Air (iOTA) revolutionizes lab testing by enabling device performance to be tested through the complete radio frequency (RF) chain under highly configurable scenarios, including playback of data from drive routes to emulate actual and familiar network conditions. In addition to traditional throughput tests, iOTA also includes application automation to run test cases simulating typical subscriber usage. While most solutions in the industry stop at running the test, iOTA provides end-to-end functionality by allowing users to precisely correlate user experience results with network information for enhanced root cause isolation. Azimuth's over-the-air platform has been accepted in a Tier 1 operator's mobile device test plan, and in the labs of the top global device OEMs. Azimuth is also actively participating in the standards process for over-the-air performance testing. As mobile networks become more complex--with the deployment of MIMO, carrier aggregation, and HetNet--so are the devices connecting to them. Both the network environment and device utilization need to be represented as precisely as possible to deliver meaningful, repeatable test results. Traditionally, testing of mobile devices in the lab occurs in conducted mode, whereby the RF port of the device is opened and connected to the testbed via a cable. This method has delivered sufficiently accurate results but has always ignored the impact on performance of a critical component of the device: the antenna. Over-the-air testing entails running the same type of tests but with network information delivered through the antenna, with the device in a shielded chamber to enable more control over environmental factors. iOTA further augments traditional over-the-air testing, by: going beyond antenna measurements typical of standard OTA solutions, to benchmark multiple devices and predict performance in market; replaying network conditions captured during drive testing for more relevant scenarios; applying application automation and network profiling analytics to enable correlation of user experience with network conditions; utilizing a portable chamber that can be reconfigured for alternative test cases in minutes rather than days.
