Conducted cable testing has been dominantly utilized in the industry to evaluate multiple-input multiple-output (MIMO) capable mobile terminals. However, direct RF cable connection introduces many practical problems. Therefore, radiated testing, where built-in antennas on the mobile terminal is utilized as RF interface to receive desired testing signals, is highly desirable. Wireless cable method is a radiated testing method, where signals can be guided over-the-air to respective antenna ports, just like in the conducted cable case but without RF cable connection. In this paper, several different ways to achieve wireless cable connection for mobile terminal performance testing in the radiated setup is discussed. Validation of the wireless cable method is done both in simulation and active throughput measurements. Future directions and applicability of the wireless cable method are also discussed.
