Is the 433 MHz band too congested to be effectively implemented for security?

0

No. Given their short range nature, active RFID tags, regardless of their frequency, would only be susceptible to congestion or interference from competing devices in their immediate vicinity. As mentioned above, the output of the tags is such that congestion is typically a non-issue. Should congestion occur because of too many SRD’s of the same type in a location (i.e. too many active RFID tags), it will first be noticeable in that SRD’s will successfully communicate with the system less frequently. As congestion in a location increases, the SRD’s frequency of successful communication continues to decrease until the system is rendered functionally inoperable. RF interference caused by an outside source of RF on the band will manifest itself through the reduction in the maximum read range possible from the SRD’s. The greater the outside source of RF interference, the shorter the read range offered by the SRD’s, eventually reducing to the point where the system is rendered functionally
