Test equipment maker Azimuth Systems Inc. has announced a test solution that enables semiconductor manufacturers, cellular phone vendors, service providers, consumer electronics vendors and PC manufacturers to accurately measure the power consumption of mobile platforms.

Azimuth said its Wi-Fi Power Consumption Benchmark Suite allows design engineers to measure power consumption during various Wi-Fi usage modes and to run profiles that can determine the impact of Wi-Fi connectivity on a device's battery life. The new suite runs on the company's W-Series platform and enables manufacturers to optimize device design and power consumption algorithms to help extend the battery life of mobile Wi-Fi devices.

Wi-Fi is being embedded into many battery-operated devices, imposing additional power demands on their already strained batteries. Because battery life significantly impacts the user experience of these devices, manufacturers must identify the factors that lead to battery drain. Although measuring power consumption is a relatively simple process, correlating its affect on battery life for Wi-Fi-enabled devices presents a challenge for most manufacturers. The reason is that mobile devicesespecially those that include Wi-Fi capabilitiesoperate in a variety of states with variable power requirements.

Azimuth said its power consumption tester is the first solution that can measure current and voltage in various operational states, allowing vendors to predict average power consumption over the life of a typical battery. The flexible tool enables users to create profiles to test the effects of various modes of operationincluding off, Wi-Fi disabled, idle (associated or unassociated) and activeas well as different device configurations and traffic characteristics. The test suite can be used to measure power consumption over a fixed time period, over the entire life of a battery, and as a device switches between usage modes or configurations.

"Battery life of mobile devices can be an important differentiator for mobile vendors and service providers," said Jeff Abramowitz, VP of marketing at Azimuth Systems. "The Azimuth Wi-Fi Power Consumption Benchmark Suite provides flexible, easy-to-use and repeatable methodology that can be used to improve products."

The Wi-Fi Power Consumption Benchmark Suite is a software that runs on the Azimuth W-Series test platform. The software can also run on Azimuth's voice handset test solution, the VTB-VHS, or can be delivered as part of a pre-packaged bundle specifically aimed at power consumption, the EDB-PCT.

The new power consumption suite leverages Azimuth's unique testing approach, which provides unmatched repeatability, flexibility and automation for wireless data communications testing, the company said. The test solution utilizes Azimuth Director Test Executive software and device libraries for test automation and precise parameter control. RadioProof enclosures are used to ensure repeatability and Azimuth's patented SmartMotion technology emulates motion in a controlled environment. The company's Real2Real architecture enables validation of data for mobile clients against a variety of commercially available access points.

Pricing is $8,000 for software to use on an existing platform, and $39,900 for the complete bundled solution. The Power Consumption Benchmark Suite software will be available in August and the W-Series platforms for the test are in production.
