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. →

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 →

http://www.vox.com/2016/5/27/11797924/cellphones-cancer-bad-reporting Another bad research reporting is spreading FUD that cell phones would cause cancer – and many magazines spread this false “news”. Stop this kind of bad science reporting. →

I wrote in earlier in New Full Duplex Radio Chip Transmits and Receives Wireless Signals at Once posting about article New Full Duplex Radio Chip Transmits and Receives Wireless Signals at Once – IEEE Spectrum that told about a new chip that makes full dupled radio communications (tranmitting and receiving at the same frequency time at →

New Full Duplex Radio Chip Transmits and Receives Wireless Signals at Once – IEEE Spectrum http://spectrum.ieee.org/tech-talk/telecom/wireless/new-full-duplex-radio-chip-transmits-and-receives-wireless-signals-at-once A new chip by Columbia University researchers uses a circulator made of silicon transistors to reroute signals and avoid interference from a transmitter and receiver that share the same antenna. The chip enables them to work around the principle →
