It defines the forward and return link parameters for technical attributes including, but not limited to, operating frequency, operating channel accuracy, occupied channel bandwidth, maximum effective isotropic radiated power EIRP , spurious emissions, modulation, duty cycle, data coding, bit rate, bit rate accuracy, bit transmission order, and, where appropriate, operating channels, frequency hop rate, hop sequence, spreading sequence, and chip rate. It further defines the communications protocol used in the air interface. The system comprises Interrogators, also known as readers, and tags, also known as labels. An Interrogator receives information from a tag by transmitting a continuous-wave CW RF signal to the tag; the tag responds by modulating the reflection coefficient of its antenna, thereby backscattering an information signal to the Interrogator. The system is ITF, meaning that a tag modulates its antenna reflection coefficient with an information signal only after being directed to do so by an Interrogator. Check out our FAQs.

They are creating RFID air interface standards for the item identification world. You can visit the ISO web site to get more details and order the documents or you can get them from your local National Body. Visit ISO. Each of the parts are at different stages see below. The updates are in one main area but also include other things as detailed below:. A revision to all the parts of will include fixes to the standards based on actual issues discovered during the use of the standards along with the addition of the capabilities to use batteries and sensors with the existing technologies.

For more information on this and any other RFID standard, contact steve hightechaid. The standard is a seven part currently standard with the following parts:. As can be seen, each of these parts deals with a different aspect of RFID. The first part is the defining document that explains how the standard works and the rest are divided by frequency.

The subsequent parts of this Standard providing specific values for Air Interface Definition Parameters shall then, once approved, provide the frequency specific values and value ranges from which compliance to or non compliance with this Standard can be established.

This Standard limits its Scope to transactions and data exchanges across the air interface at Reference Point Delta. See Section 4, fig 1. The means of generating and managing such transactions, other than a requirement to achieve the transactional performance determined within this Standard, are outside the scope of this Standard, as is the definition or specification of any supporting hardware, firmware, software or associated equipments.

Standardisation of other Reference Points are outside the scope of this Standard. See fig 1. Below This standard is an enabling standard which supports and promotes several RFID implementations without making conclusions about the relative technical merits of any available option for any possible application. The physical layer that shall be used for communication between the interrogator and the tag. The method to detect and communicate with one tag among several tags "anticollision".

These two types differ only by their physical layer. Both types support the same anti-collision and protocol. FDX tags are permanently powered by the interrogator, including during the tag-to-interrogator transmission. They operate at kHz. HDX tags are powered by the interrogator, except during the tag-to-interrogator transmission. They operate at To claim compliance with this standard, a tag shall be of either Type A or B. NOTE Nothing in this standard prevents a tag to be of both types, although for technical reasons, it is unlikely that such tags are ever marketed.

To claim compliance with this standard, an interrogator shall support both Types A and B. See Annex C. Two type A and B, interrogator must support both. Three Modes. The Interrogator to Tag data rate is 1. The Tag to Interrogator data rate is Mode 3 is a high speed interface with two options. Both use the C command structure to be compatible with EPCglobal. In option 1 the Interrogator to Tag data rate is Typical applications operate at ranges greater than one meter.

Two modes. Mode 1 is a passive tag, mode 2 is a battery assisted, tag talks first tag. The tag is battery assisted but back scattering. By using of battery powered tags such a system is well designed for long-range RFID applications. This air interface description does not explicit claim for battery assistance in the tag, also real passive tags or tags for mixed operation are conceivably. This part of the standard was abandoned due to insufficient global interest.

For the collision arbitration, Type A uses an Aloha-based mechanism, Type B uses an adaptive binary tree mechanism. In the forward link it uses Pulse Interval Encoding at This prevents the Tag from talking all the time and blocking other types of tags from communicating. The host system runs an application program, which controls interfaces with the RFID. The RFID equipment shall be composed of two principal components: tags and interrogators. The tag is intended for attachment to an item, which a user wishes to manage.

It is capable of storing a tag ID number and other data regarding the tag or item and of communicating this information to the interrogator. The interrogator is a device, which communicates to tags in its field of view. Additionally, the interrogator can use its transmitted RF carrier to power the tag. Systems, which rely on the transmitted interrogator carrier for powering the tag, are typically referred to as passive tag systems.

The interrogator controls the protocol, reads information from the tag, directs the tag to store data in some cases, and ensures message delivery and validity. RFID systems defined by this standard provide the following minimum features:. The updates are in one main area but also include other things as detailed below: A revision to all the parts of will include fixes to the standards based on actual issues discovered during the use of the standards along with the addition of the capabilities to use batteries and sensors with the existing technologies.

An optional anticollision is described in the informative annex D. Interrogator To claim compliance with this standard, an interrogator shall support both Types A and B. Mode 2 is a high speed interface. The Interrogator to Tag data rate is HTA Comment: Two modes.
