Optical links may soon complement Wi-Fi in some situations, with higher data rates, security, and RFI resistance, but are engineers ready for the world of advanced optical test and measurement? The dramatic proliferation of wireless devices has forced engineers who don't have much RF background to become somewhat RF-knowledgeable and meet performance standards. Fortunately, in many cases, the required tests are well-defined, the needed equipment and test suites are available, and there's often a specialist with experience on the team or one within reach.
