Trolley Scan (Pty) Ltd, a Johannesburg, South Africa based developer of RFID (Radio Frequency Identification) technologies announces the release of a report on measurements of UHF radio spectrum usage for different air-protocols in use with different RFID designs.

Radio Frequency Identification uses part of the radio spectrum for its operation. This is a precious resource as the available spectrum is limited, in some countries more so than in others.
As more and more users will want to use this technology as it increases in popularity, so will the demand on the spectrum.

By careful selection of the optimal air protocols between the reader and the transponders in the RFID system, many users can share the available spectrum.

"The study shows measured results of the different spectra in the UHF band of the different protocols using advanced spectrum analysers and signal generators. These results allow an understanding of the issues involved and indicate why a change from certain protocols that are currently promoted needs to be made as the industry matures." Says Mike Marsh, Managing Director of Trolley Scan.

A technical report on the tests has been written such that novices with little understanding of radio issues can follow the arguments as well as those well versed about these matters.
