Automatic Transmit Power Control for responsible use of GURL frequencies outdoors
Ever since mass-produced outdoor General User Radio Licence (GURL) products hit the market, there has been the fear that the entire 2.4GHz and 5GHz bands would collapse and become completely unusable. This is true in some high-density urban city areas and certain radio towers. What we tend to see though is that the manufacturers are always keeping one step ahead and are working on the next piece of technology, enabling them to continue selling their products and services.
Antennas, in essence, channel electrical power into electromagnetic signals. The shape, size, and connectorization all affect the antenna radiation pattern. Two key parameters in assessing the performance of an antenna are directivity and gain―directivity is a measurement of the concentration radiation in a direction while gain represents the power transmitted in the main beam.

A more eclectic bunch, and a larger range of not only vendors, but technologies too.

Two Way Radios – An essential part of your business toolbox
Going back a few years now it seemed that mobile radio was nearing the end of its life with our typical users as cellular coverage grew and everyone had a least one cell phone, then came the reality that cell phones do not replace mobile radio.
IOT – so what’s new?!
Internet of Things (IOT), Internet of Everything (IOE), both buzz words of the minute. Confusing to some, scary to others, but what we as an industry group need to know, is that we have been delivering these sorts of systems for a long time now.
