This document provides an overview of the MCELLBLOCK platform for automated mobile network testing using real devices. Some key points: - MCELLBLOCK allows running thousands of automated tests on hundreds of real mobile devices to validate 3G, 4G/LTE, 5G and WiFi networks and services. - It supports most Android and iOS devices and enables both automated and manual testing at scale. Tests can validate various aspects of the mobile network including voice, data, applications and more. - The platform includes hardware racks that can hold up to 320 devices organized into modular cell blocks as well as automation software and a library of test scripts for common functions and applications.

13. Automation Life Cycle – Using Real Devices
• Today – Manual tests occurs at a point of change. New Device, New OS,
New Application, Network upgrades and changes → MCb Manual Test
• Automate Manual Test –
• Allowing tests to occur multiple times a day, finding problems quick and early
• In wireless the test path is always changing: Device, OS, Application, Network
Capacity, Platform, …
• Understand User Group TOL requirement
• MCb & User → Steps through Application with target device/OS
• Expected Results
• Validation Points
• Points of Interest
• Exceptions – Items not easily addressable by automation
• Logs / Video / Checkpoints for all or failed tests
• Implement TOL – Orchestrated through Automated Network Test, ANT
