This page was last edited on 27 Novemberat In response to a valid command each tag randomly selects a channel on which to transmit its reply. Tags reply to the interrogator by inductive coupling whereby the voltage across the tag antenna coil is modulated by a subcarrier. In addition to random channel selection the tags can randomly mute individual replies.
By Claire Swedberg Tags: However, a handful of unnamed end users are currently testing prototypes of RFID readers and tags that work with the standard, primarily in the gaming industry, as well as for document tracking and item-level logistics—all areas in which tags will be densely contained.
Primary applications are in RFID tags for use in gaming, healthcare, pharmaceuticals, document and media management. The air interface operates as a full-duplex communication link.
Ios stored time stamp defines precisely when the tag first entered the interrogator and provides a high-resolution method of determining tag order, which is decoupled from the speed of identification. The powering field frequency is Views Read Edit View history.
The reply data rate is Yes—we have deployed RFID and our operations have improved. Commands are transmitted from the interrogator to the tag by phase-jitter modulation PJM  of the powering field. The target markets for MODE 2 are in izo systems for manufacturing, logistics, retail, transport and airline baggage.
Tags, Readers Compliant With the ISO 18000-3M3 Standard Expected Soon
Upon receiving the next valid command each tag randomly selects a new channel and transmits the reply ido the newly selected channel. Parameters for air interface communications at There is no reduction in the transfer 18000–3 power to the tag during PJM, and the bandwidth of PJM is no wider than the original double-sided spectrum of the data.
By utilizing the new standard, RFID interrogators can read many more tags simultaneously, and much more quickly, compared with most currently available passive HF tags that is, those complying with the ISO or ISO standard.

Random muting is necessary when identifying very large populations of tags during singulation. The interrogator operates with full-duplex transmissions being able to transmit commands while simultaneously receiving multiple tag replies. Concepts, Practical Experiences, Technologies. The higher-powered version, says David Rutherford, Optys’ business development and sales manager, will be able to read more tags, and faster—at a rate of up to tags per second, he says, as opposed to several dozen tags per second, which the lower-powered version is capable of reading.
Wo die wirklichen Gefahren lauern” [New Identity Card: The reply is transmitted once using the selected channel. When a reply is muted, the tag will not transmit that reply.
The interrogator can selectively mute identified tags to remove them from the identification process. When a tag is muted, the tag will not transmit any replies.
All commands are time-stamped, and tags store the first time stamp received after entering an interrogator. Handbook of EID Security: This method of reply frequency hopping using random channel selection is repeated for each subsequent valid command.
Optys’ existing reader is low-powered, while the firm is working to create a high-powered version that is expected to be made available next month. The subcarrier is derived from division of the powering field frequency.
