OmniAir Overview

Updated November, 2013

OmniAir is an industry led trade association committed to the development of certification in intelligent transportation.

• Certification policy, structure, development • Support of national tolling interoperability • Support of standards for certification for electronic payments, connected

vehicle, tolling and commercial vehicles applications

OmniAir Certification Services (OCS) is an independent sister organization of OmniAir. We independently certify components and processes to the to the specifications that OmniAir or other clients develop.

Conformance Testing

• These tests ensure that a device has implemented all functionality correctly.

• Both radio and protocol commands are tested. • For example, tests verify that a tag responds in the correct

amount of time to a reader command.

• These tests also ensure that a reader will not interfere with other readers by virtue of meeting multiple or dense interrogator masks.

• A device has to pass all tests at this level to obtain certification. • A sophisticated test apparatus developed by National

Instruments can prove beyond any doubt whether a device conforms or not.

Baseline Test Suites

Read EPC when Perma-Locked and when Access Password is Zero This test case tests the ability of a reader to properly read the permanently locked EPC when the Access Password on the tag is Zero. At the same time verifies that the tag is able to correctly transition from Ready Reply Acknowledged Secured states.

Write EPC when Perma-Locked and when Access Password is non-Zero Verifies that a reader cannot Write to EPC when it is permanently locked even when the correct non-zero password is used. Also, verifies that the tag transitions from Ready Reply Acknowledged Open Secured states.

Perform a matching Select followed by a Query consistent with the Select matching action such that the tag responds with its EPC. Several iterations of this test are performed changing parameters such as the Target, Action, Pointer, Truncate, Lock etc.

Test Cases (examples out of ~300)

There are close to 300 test cases, such as the above, that fully exercise the state table in the specification. Several iterations of some test cases are performed with changing

parameters. 50 tags are required to complete test cases

A scripting language such as Perl on the reader is desired to run through the test cases in an efficient manner.

Using referenced readers or tags Already a proven approach Confidence that a tag and a reader interoperate Baseline for Applied Testing

Environmental Tests

Additional Tests:

Temperature testing (-40-90+ Celsius) Humidity testing (50-93%) UV testing (400 hrs. of exposure) IR testing Future (shock absorbance, salt)

Measurements taken with many parameters: distance between a tag and toll antenna

tags mounted on specific heights (motorcycle, car, truck)

tags placed at different positions on the windshield tested at different speeds ( ,,,85mph)

changing tag orientation (angles)

changing antenna orientation (angles)

analyzing interference (single lane, multiple lanes, open lanes).

Applied IOP Tests Summary

Wealth of systematically collected data will allow toll agencies to select interoperable tags and readers that meet their needs.

Builds on Baseline testing Reduces a need for “shootouts” Allows fair comparisons Final result: “true interoperability”

OCS Accreditation

Requirements • Quality system based on ISO 17025 • Current scope: 6C

• Other scopes in development • Need to use OCS Qualified Test Tools • OmniAir member

OCS is open to accredit additional test labs • To increase competition among test labs • Provide regional service

Accreditation • Initial Accreditation

• By independent auditor • Re-Assessments (yearly)

• Desk Audits 1 year • Physical Audit 2nd year

Fees • Test lab determines test fees (not OCS) • Test lab pays OCS:

• Accreditation Fees • Reassessment Fees • Collects OCS Certification Fees from the client
