White paper on RFID usage of the radio spectrum with different air protocols
24 January 2007
News
Trolley Scan has completed an important research project on looking at the use of the very limited radio spectrum by RFID (radio frequency identification) applications. Unless something is done, RFID will strangle itself by being wasteful with the precious spectrum resource.
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 than in others. As more and more users will want to use this technology as it increases in popularity, so the demands on the spectrum will escalate.
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. This paper from Trolley Scan shows measured results of the different spectra 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.
The document 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.
