Drive Test
Drive Testing is a method used in the mobile phone and wireless industry to check how well cellular networks perform in real-world conditions. It involves driving around in a vehicle equipped with special testing equipment to measure signal strength, call quality, data speeds, and other network parameters. This helps phone companies ensure their networks work properly everywhere their customers go. People might also call this "network testing," "RF drive testing," or "mobile network testing." It's like doing a road inspection, but for cell phone signals instead of road conditions.
Examples in Resumes
