"Reflectometer Measurements - Revisited"

Twenty-four years ago Wiltron (nor Anritsu) published a Technical Review "Why Tolerate Unnecessary Measurement Errors," long since out of print.  Thousands were printed and it was widely used by test engineers.  This review will include some of the material originally presented in 1975 - as it still very important - and addresses problems that regularly appear in current applications.

"Practical Tips on making WiMax field measurements Part 2"

Worldwide Interoperability for Microwave Access (WiMAX) digital communications technology is based on wireless transmission methods defined by the IEEE-802.16 air interface standard. Intended for wireless metropolitan area networks, it provides broadband wireless access up to 30 miles for fixed stations, and 3 to 10 miles for mobile stations. WiMAX has a range of potential uses, including providing high-speed mobile data and telecommunications services (such as 4G), as a wireless alternative to cable and DSL for last mile broadband access, and to connect Wi-Fi hotspots with each other and to other parts of the Internet.
