22 May, 2013 by Larry Hardesty, MIT

Hardware breakthrough could see wireless devices that identify and exploit unused frequencies.


Antenna system monitoring

20 February, 2013

The measurement, monitoring and reporting of the performance of wireless network infrastructure has come a long way over past years. Many modern base station repeaters provide integrated measurement capabilities, but the use of combining and/or isolators in the RF path from the base station transmitter output to the antenna isolates the repeaters from most problems that may occur within the combiner and antenna subsystems.

Understanding the hidden power rating of antennas

14 March, 2012

There are a number of antenna specifications that determine the selection of an appropriate antenna for a particular application. These may include bandwidth, directivity, gain, pattern stability and the PIM rating. Another important antenna rating, becoming more relevant in recent times, is the PIP rating, summarised in this article.
