Why Wi-Fi Stinks—and How to Fix It – IEEE Spectrum

http://spectrum.ieee.org/telecom/wireless/why-wifi-stinksand-how-to-fix-it?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+IeeeSpectrum+%28IEEE+Spectrum%29&utm_content=FaceBook This article is a very good overview on today’s WiFi wireless networking problems. WiFi is so popular that it works more or less baddly for many users. And new standards that promise more speed do not make WiFi more reliable.

Finding faults in coaxial cables

Coaxial cables are essential transmission lines in many RF/microwave applications. Coaxial cables are usually reliable, but sometimes coaxial cables can develop unseen faults that may be anywhere in their length. Finding those faults can often be challenging, typically requiring the use of time-domain reflectometry (TDR) which operates much like a radar system. Analysis of the reflected
