Verification of coexistence measurement methods: Radiated anechoic and open environment

With an abundance of wireless devices saturating daily life, the ability of devices to coexist among other devices is of increasing interest. While standards are starting to incorporate coexistence measurements, the robustness of coexistence measurement methods is still an area of active research. To demonstrate the robustness of the multiple test methods, a series of measurements needs to be conducted that compare a measurement methods. Ideally, if the same coexistence test is performed by use of each of the four methods, the end result should be the same. Here, we compare two popular radiated test methods: an anechoic chamber test and a radiated open-environment test. Both methods are part of the ANSI C63.27 standard. We examine the impact two of the possible environments may have on the outcome of a coexistence test. For this, we use Bluetooth low energy and Wi-Fi networks. Overviews of generalized coexistence testing and future work are also presented.
