Benefits of technology

The present invention provides a RFID system and tag that can communicate with different readers using different protocols and standards without added complexity. The tag design can be kept relatively simple minimizing manufacturing costs and tag dimensions. The use of time-division multiplexing allows for one tag to provide its ID or other information via one or more protocols and standards, simultaneously or selectively to different readers.

Problems solved by technology

However, this raises the cost of the item considerably and precludes low cost items from access to such multi-protocol systems.
This also adds cost and size to the tag.

Embodiment Construction

)

[0037]The exemplary embodiments of this invention will be described in relation to RFID systems, and in particular to RFID systems using TTO tag(s) that are configured to receive power from an interrogating reader (passive tag), but also battery-powered TTO tag(s) that are configured to continuously broadcast information, either autonomously or when activated by an interrogating reader. As non-limiting examples, the tag(s) could be operated at 860 MHz to 960 MHz, 13.56 MHz or 125 / 134 KHz and according to any one of the standards and classes shown in FIGS. 2 (a) and (b).

[0038]However, it is understood by a person skilled in the art that any other suitable tag design (passive, semi-passive, active) may be used in connection with this invention. Also, it is understood that the scope of the invention is not limited to the specific design described for the example embodiment(s).

[0039]Further, in the context of this particular example of the present invention, signal transmission include...

Abstract

The present invention provides for a RFID tag assembly that is suitable for operation with at least one RFID reader assembly. The RFID tag assembly comprises, inter alia, an antenna member for transmitting and / or receiving an RFID signal, and at least one integrated circuit (1C) for processing the RFID signal and which is configured to communicate, alternatingly and sequentially in time, a first signal transmission and at least one second signal transmission, each defined by a plurality of predetermined signal transmission parameters, to the at least one RFI D reader assembly, utilising time-division multiplexing, wherein the at least one first signal transmission differs from the at least one second signal transmission in at least one of said plurality of predetermined signal transmission paameters.

Description

[0001]The present invention generally relates to wireless RF (Radio Frequency) communication and particularly to an electronic tag such as a RFID (Radio Frequency Identification) tag adapted to simultaneously communicate with one or more reader(s) utilising different communication protocols / standards.INTRODUCTION[0002]Applications of radio-frequency identification (RFID) are widespread in today's well-connected world. RFID uses radio frequency (RF) signals to identify and track objects, such as, for example, vehicles, shipping containers, equipment, tools and even personnel utilising so called tags (i.e. transponders) that are attached to the object. In some cases, RFID may also be used to provide information about the tracked object's state, such as, for example, temperature, humidity or a precise location.[0003]Typically, RFID systems are categorised according to the operating carrier frequency. For example, Low-Frequency (LF) RFID operates at 125 KHz to 134 KHz (kilohertz), offer...
