Accurately replicates subscriber experience from device to services, for full-stack validation in controlled lab environments

FREDERICK, Md.--(BUSINESS WIRE)--Jun. 25, 2025-- Spirent Communications plc (LSE:SPT), a leading provider of test and assurance solutions for next-generation devices and networks, today announced the launch of the Landslide E20 Over-the-Air (OTA) solution, an innovative, scalable test platform that introduces true end-to-end testing by automating interactions with real handsets in lab environments. The solution enables the validation of app, service, device, and OS performance across 4G, 5G, and Wi-Fi networks, including support for complex scenarios such as mobility and roaming.

The telecommunications industry is facing growing pressure to validate handset performance, service quality, and operating system updates before rolling them out on a large scale. Traditional lab setups that emulate portions of the network cannot capture the complete subscriber experience that real devices deliver in the field. Spirent's Landslide E20 OTA solution addresses this critical gap by delivering a solution with integrated software, customizable scripting, and support for dual SIM scenarios. It is the only platform to provide carrier-grade automation and visibility into real handset behavior and is scalable to support hundreds of devices simultaneously.

"Ongoing evolution of 5G, Wi-Fi offload strategies, and new handset and OS releases demand an automated, repeatable approach to testing in realistic conditions," said Anil Kollipara, Vice President of Product Management, Spirent. "Our Landslide E20 OTA solution delivers full-stack visibility and real-world accuracy, validating services under true user conditions. This platform uncovers performance issues others miss, with scalable testing across devices, OS updates, and mobility scenarios."

Key capabilities of the Landslide E20 OTA solution include:

• End-to-end validation: Complete subscriber experience testing from handset through RAN to core network
• Real device automation: API/SDK-based automation that is immune to UI changes to ensure long-term reliability and lower maintenance overhead
• Concurrent use-case simulation: Reflects realistic multi-app usage like video streaming and voice calls running simultaneously
• Custom test scripting with remote UI control: Allows distributed CSP teams to create, automate, and manage tests for apps unique to their networks without physical lab access
• Scalable architecture: Purpose-built rackmount platform designed for carrier-grade lab environments

Landslide E20 OTA is built for mobile network operators, handset manufacturers, and lab automation teams and addresses critical applications including mobile core and RAN validation, device and OS certification, app performance assurance, network slice behavior, 5G/Wi-Fi offload, and roaming scenario testing. It is part of Spirent's lab-to-live assurance strategy, enabling CSPs to validate services in the lab under real conditions before launching and aligning with live network monitoring. By combining OTA lab testing from Landslide with VisionWorks for live mobile network management, Spirent enables continuous validation from development through deployment, uniquely positioning the company as the only vendor delivering solutions for full-lifecycle, real-device service assurance.

“The Landslide E20 OTA solution further reinforces our leadership in scalable, end-to-end service assurance and represents a critical advancement in lab-based OTA testing for the telecommunications industry,” said Kollipara.
