Standards Update – 3 – February 2011

This month there are a series of ISO RFID standards meetings taking place in Sarasota, FL USA.  The third meeting was SC 31/WG 4/SG 3.  This committee is responsible for RFID air interface standards –  ISO/IEC 18000 series standards.

All of the parts of ISO/IEC 18000 have been published, but work items are currently open to revise parts 6 and 7.

ISO/IEC 18000-6 is the air interface standard for 860 – 960 MHz UHF RFID. This standard was revised and published in 2010 with the addition of a Type D and support for sensors and battery assist. The addition of these options to the standard meant that the document had grown to almost 500 pages.  A new work item to break this standard into smaller parts was approved at the end of 2010 and the committee met, for the first time since that approval, to review the work that has been done.

The standard has been broken into five parts:

  • Part 6: Parameters for air interface communications at 860 MHz to 960 MHz General
  • Part 61: Parameters for air interface communications at 860 MHz to 960 MHz Type A
  • Part 62: Parameters for air interface communications at 860 MHz to 960 MHz Type B
  • Part 63: Parameters for air interface communications at 860 MHz to 960 MHz Type C
  • Part 64: Parameters for air interface communications at 860 MHz to 960 MHz Type D

Each of these parts was approved to move to the first stage of balloting – CD ballot. For more details of how the ISO process works see: http://www.understandrfidstandards.com/how-does-iso-work/

ISO/IEC 18000-7 Parameters for active air interface communications at 433 MHz was last published in 2010. This standard has been opened to revise the technology to include multi-channel utilization and more efficient communication techniques needed to address increased market and application needs for higher and more secure data transmissions. This revision will also specify the sensor interface and a universal mechanism to allow for other services to be enabled on the tag.

Standards Update – 2 – February 2011

This month there are a series of ISO RFID standards meetings taking place in Sarasota, FL USA.  The second meeting was SC 31/WG 7.  This committee is responsible for security and file management of the ISO/IEC 18000 series standards. The standard is ISO/IEC 29167 and it is still in the early stages of development.

The meeting was well attended with 25 people from 13 National Bodies and Liaison organizations.

Part 1 of this standard is the overall architecture and this document is already in ballot at the CD stage (see http://www.understandrfidstandards.com/how-does-iso-work/ for details of the process).

The standard is broken into several parts – the first is the general information, but the remainder define the specific methods to implement security and file management in the specific frequency dependent parts of ISO/IEC 18000.  The first part of the work is on a method to implement in ISO/IEC 18000-6.

The work of this group on the UHF specific implementations is being kept in step with the work of GS1 EPCGlobal. This has slowed the work a little, but the progress has been good.

The two parts to the work are File Management and Security. For File Management, the goal is to produce a method to provide a standardized way of accessing user memory on a tag that conforms to ISO/IEC 18000-6. The concept can be thought of as similar to a hard drive on a PC where we have a file management scheme that we call folders. The committee is addressing how this can be achieved on a tag.

The second part of the work is on Security. The committee is creating a means to implement encryption based security on a tag. This security option will be presented in a standard fashion with a collection of optional security suites (such as AES, Triple DES etc.). The tag and reader will negotiate a common security method and then communicate through this encryption.

This work will allow for the authentication of tags and readers thus enabling many new applications for RFID. The ability to hide data in an encrypted form gives a RFID the ability to satisfy the needs of the users to effect a scheme that will enable privacy of data.

Standards Update -1 – February 2011

This month there are a series of ISO RFID standards meetings taking place in Sarasota, FL USA.  The meetings started with a meeting of SC 31/WG 4/SG6. This committee is responsible for the conformance and performance standards as they apply to the ISO/IEC 18000 series of standards.

The meeting was well attended with 19 people representing 11 National Bodies. The meeting included comment resolution meetings for ISO/IEC 18046-1, ISO/IEC 18047-2, and ISO/IEC 18047-3.  All of these comment resolution meetings, were able to resolve all the comments and they agreed to move the documents on to the next stage of the standards process. (see http://www.understandrfidstandards.com/how-does-iso-work/ for details of the process).

In the subsequent committee meeting the following items were reported:

  • Review of progress of WI 18046 RFID Performance testing
    • ISO/IEC 18046-1 – FDIS to start
    • ISO/IEC 18046-2 – FDIS closes this week

 

  • Review of progress of WI 18047 RFID Conformance testing
    • ISO/IEC 18047-2 – move to FCD
    • ISO/IEC 18047-3 – move to publication
    • ISO/IEC 18047-6 – published Jan 11, 2011, needs to be revised because of the new Work Item that splits 18000-6

The committee also review a document that details the availability of performance and conformance documents for all of the RFID standards created by ISO/IEC JTC 1/SC 31/WG 4.  The document was approved for submission to WG 4 with a recommendation that is becomes an SC 31 level document with input from other Working Groups in SC 31.

RFID Standards in 2011

Happy New Year:

Welcome to 2011.  What will we see in this new year with regards to RFID Standards?

Now that I have posted the basic information about the ISO/IEC 18000 series of air interface standards, I will start to look at the new work as well as talking a little about work outside of the air interface.

Please let me know if there is anything special you want covered, and don't forget to sign up for any special information about RFID Standards that I release.
