Seamless communication is critical to the successful execution of military operations, but ensuring reliability from communications systems and devices is rapidly becoming ever more difficult. More protocols, more frequency bands and more applications all add to the complexity of developing and testing military communications equipment so that it performs with an advanced degree of reliability in the field—and ensures both mission success as well as the safety of the military personnel that depend on it. However, ensuring the latest tactical radio systems consistently perform as expected presents a number of unique challenges given dangerous battlefield conditions and the often harsh, remote terrains where military communications systems must operate.

Testing today’s advanced smartphones and mobile devices involves many phases. The final predeployment test typically is device validation, commonly performed under the field conditions where the subscribers will actually use them. However, device field testing across diverse conditions of terrain, population density, physical location, and motion is extremely time-consuming and costly and lacks repeatability.
Wireless Design & Development, May/June 2011
Real-world drive testing is very expensive; lab testing is much less expensive and faster—provided that the real world can be emulated with sufficient fidelity. Field-to-Lab allows service providers, equipment manufacturers, and chipset vendors to take real-world drive test logs collected from around the globe, and replay the data in the ACE MX MIMO channel emulator in order to effectively recreate actual field conditions in any lab, during any phase of the equipment design and qualification cycle for equipment benchmarking, troubleshooting or many other purposes.
