RF testing of wireless communication technologies has always been a complex and nuanced endeavor with many considerations and trade-offs, similar to making the ultimate lemon meringue pie. With the advent of more sophisticated communication protocols (5G and Wi-Fi 6e) and hardware techniques, such as MIMO/beamforming and heterogeneous networks, more advanced RF testing systems have emerged. Of course, this is necessary. We aren’t talking about just cellular for smartphones or Wi-Fi for tablets and TVs anymore. Almost every electronic device will eventually have a radio in it, and more non-electronic systems are being electrified and given sensing and reporting capabilities. Now modern communication devices must struggle alongside a growing number of sibling devices all screaming for attention. |
