Cognio expands its technology for spectrum analysis to support wireless management of RFID devices. ...
... "The unlicensed bands are becoming increasingly congested as more devices, and types of devices, are now available and in use. Wireless networks are also proliferating at a staggering rate, with the leading networks leveraging the unlicensed band for RFID and WiFi. This makes managing these networks and devices challenging for wireless IT managers as they operate in the most difficult spectrum to control -- the unlicensed spectrum, where these networks must compete for resources with other devices that use these frequencies. To combat the growing problem, network professionals need tools that can quickly troubleshoot the physical layer. For RFID networks, the need is to be able to determine whether there are interfering devices and to test to verify the power transmitting from RFID readers as either can significantly undermine network availability and reliability. For WiFi, the problem is to ensure that connectivity problems are not being caused by physical layer problems. In both cases, Spectrum Expert solves these problems by enabling wireless IT manager to identify and locate interfering devices quickly before they can bring down or impact the network. " ...

Tektronix: Applications > RF > RFID: "The main purpose of this application note is to demonstrate using a Real-Time Spectrum Analyzer to evaluate an RFID system's compliance to ISO/IEC standards as well as government regulations regarding intentional transmitters (i.e. FCC 47 part 15, ARIB STD-T82, and EN 300 330)."
Real-Time Spectrum Analysis In RFID Testing About RFID Transmission protocols Real time spectrum analysis: "The testing requirements for RFID signals cover not only the traditional RF measurements of frequency, spectral emissions, power and power versus time (because of the time-varying nature of the signal) but also analysis of the short bursts of modulation. The situation is further complicated by the fact that signals are present only for a short time, have vastly differing power levels and could even be frequency-hopping."
Spectrum Analyzer measures 3 distinct frequency bands., Berkeley Varitronics System: "Interfacing with iPAQ PocketPC, RF-calibrated BumbleBee measures 2.400-2.500 GHz, 5.150-5.900 GHz, and FCC designated Public Safety band of 4.940-4.990 GHz. Spectrum analysis features include 3 waveform traces, peak hold, peak search, and user-selectable packet/interference triggers. Unit allows on-the-fly switching of bands for real-time spectral analysis of wireless standards including RFID, VoIP, 802.11, cordless phones/ video, and broadband public safety data networks."
