Modular test, measuring, and analysis solutions for the optimization of NFC interface design
The NFC interface design is key for a good performance of NFC applications. This is because NFC can only work fine if the involved interfaces are designed properly. Hence, field coverage, reader sensitivity, functionality, and, overall interoperability adhere to global standards. Therefore, CL Development Line provides means to validate all these aspects of NFC design. So, it is absolutely necessary for the optimization of NFC antennas.
The operating volume defines the three-dimensional space in which an NFC-enabled device running in poll mode is able to communicate with an NFC listener.
To optimize transfer within, the strength of the magnetic field must be sufficiently high. In addition, the ability of the reader, aka "Poller" in NFC Forum terms to detect a card or so-called "Listener" is key. It must differentiate a weak signal from noise. This is called "sensitivity" or "receptivity".
Design Validation Center together with the calibrated CL Development line hardware provides measuring means for validating an NFC operating volume. Thus, designing it according to the requirements of the application is a lot faster with:

Do you have doubts that interacting NFC items are not compatible with each other? Or does it seem that they do not completely understand each other? Or do you just want to have a look into the data exchanged on the contactless interface to understand what is going on?
All this issues can be clarified with COMPRION interoperability testing tools.
COMPRION's solution for interoperability testing on the contactless interface shows in a convenient way if partners talking via the NFC interface speak the same language and if there are communication errors. It provides a protocol analyzer for debugging real NFC communication on all NFC layers.
It offers comprehensive measurements and analysis features, such as:
The solution consists of:
Standardization bodies such as NFC Forum, EMVCo, and ISO specify standards for the implementation of NFC technology. They also define the testing for checking if the implementation has been done successfully in conformance with this standards. This procedure is named conformance testing and is done at certified test houses.
COMPRION offers the appropriate hardware and software to execute this conformance tests already during development in the lab. The Device Test Center software comes with the same test benches used for analog and digital conformance testing at test houses:
CL Development Line allows to run this test benches in the own lab on calibrated measuring devices. So, conformity with standards during development can be proven at an early stage and costs for repeated test sessions in test houses are reduced.

NFC enabled device, tag or contactless card.
Individual functions of an NFC-enabled device are out of the scope of the tests defined by standardization bodies such as NFC Forum or EMVCo. But this functionality must also be tested to achieve a good overall quality of the respective components. For extending test coverage beyond conformance standards, programming interfaces are needed, which allow creating individual test scenarios.
For this purpose, the hardware components of CL Development Line are controlled by Device Test Center.
Together with the NFC Test Designer, you can:
