Definitions
- This embodiment has a second error-checking reflector group located on the substrate that is dependent upon data contained in the at least one tag identification number reflector group and the first error-checking reflector group.
- Another embodiment des for the SAW identification tag to also have a synchronizing reflector group on the substrate.
- a SAW identification tag has a first reflector group located on a substrate with reflectors that have substantially similar first reflection characteristics.
- a second group of reflectors located on the substrate has substantially similar second reflection characteristics.
- the first reflection characteristics and the second reflection characteristics are substantially similar.
- FIGURE 2 illustrated is a SAW identification tag system 200 operating in an environment where a wireless LAN device 210 and a microwave oven 215 are operating within the same ISM frequency range.
- a detection module 206 that detects the signals 211, 216 emanating from the wireless LAN device 210 and the microwave oven 215.
- the detection module 205 also detects and identifies a null period 221 in the transmission pattern 220 of the wireless LAN device 210 and the microwave oven 215.
- the null period 221 may be either a time null period 221 when no signal 211, 216 is transmitted, or it may be a frequency null period where a frequency within the ISM band is identified where no signal is being transmitted.
