GTrusted – Industry’s Connectivity Database & Test Services

Specification (spec) compliance is an important element in getting devices to work well together.  Just as critical, interoperability testing with a large diverse set of devices is needed since there is a wide range of device behaviors and spec adherence that affect the user experience.

In the past, interoperability testing was done blindly with different devices purchased from retail without a true understanding of the appropriate interaction and functional behavior.  Just because you see a green checkmark doesn’t mean that your product worked properly with another device.

The user experience depends not only on proper interaction between devices but base technology capabilities of those devices.  Often these capabilities are not reported to the user but are critical to the user getting the desired performance outcome.  Unfortunately, a lot of unverified capability information is put on the Internet and users have to rely on here-say and guesswork.

To clear all this fog of uncertainty, GTrusted incorporates a standardized framework to anyone to consistently determine proper device behavior based on technology capabilities and environmental factors.  Software automation allows side by side benchmarking comparisons and new visualization techniques to make it easier to gain insights as to what’s actually going on.  No more guesswork.

GRL offers the following GTrusted based services:


Smart Interoperability Testing

Intelligently customized extended interoperability testing with results judged for the extent of deviation from proper behavior.

Get access to hundreds of devices from around the world but optimize costs through a customized list of target interoperability devices optimized to provide just the right level of test coverage depending on-target application and region.

Automated setups with GRL testers enable consistent test results and easy benchmark comparisons to best-in-class devices or competing products.

GTrusted Database Access

Instead of everyone testing in silos, the GTrusted database allows everyone to instantly access thousand of hours of high quality, consistent, and structured test data to benchmark performance and develop smart test plans to cover a wide range of interoperability behaviors.  Professionals with GRL testers can also contribute to growing the database based on GRL test results.

Bad devices found in retail can be identified to stress test the robustness of your product.

Easily compare how well your product performs vs other products with target devices and applications.

The database content is structured to be accessible through the cloud by professionals, GRL test software, and servers.

Brand & Technology Audit

GRL can perform audits around the world at the company and industry level to evaluate the health of the brand and technology through retail sample testing and using performance, compliance, and interoperability metrics.

GRL worldwide lab locations can regularly acquire devices in different retail markets to monitor key metrics and use test data to also check for signs of counterfeiting and logo compliance.

Separately, GRL publishes benchmarking data on for the public on an ongoing basis so that users can compare products and brands based on real test data, and be alerted to issues and problems found.

Promotion Through Test

Nowadays, the user review system can be easily manipulated and its credibility compromised.

GRL offers an alternative approach where companies can promote their products online through high-quality content based on real test data.

Products can be easily compared and are scored using an objective test results-driven rating system
