Understanding the Mobile World

The intertwining of telecom, banking, and M2M/IoT produce a new degree of complexity. We hope our COMPRION glossary helps you to get a good overview of all the connected terms, technologies, and concepts.

n

Also called 4FF (4th form factor). It measures 12.3 × 8.8 × 0.67 mm and reduces the previous format to the contact area while maintaining the existing contact arrangements. A small rim of isolating material is left around the contact area to avoid short circuits with the socket. The 0.7 mm thickness of the nano-SIM is about 15% less than its predecessor. 4FF can be put into adaptors for use with devices taking 2FF or 3FF SIMs.

51f89

Industry standard for short distance contactless data exchange using radio signals. The technology is a simple extension of the ISO/IEC 14443 proximity-card standard (contactless card, RFID) that combines the interface of a smart card and a reader into a single device. An NFC device can communicate with both existing ISO/IEC 14443 smart card and readers, as well as with other NFC devices, and is thereby compatible with existing contactless infrastructure already in use for public transportation and payment.

d31d3

The Near Field Communication (NFC) standards created by NFC Forum specify different data and recording formats. These formats are necessary in order to enable NFC-compliant communication between NFC readers and NFC tags. NDEF is a lightweight, binary message format that can be used to encapsulate one or more application-defined payloads of arbitrary type and size into a single message construct.

6558c

Dedicated report intended for those users who intend to apply for certification at the NFC Forum. If you want to certify mobile equipment according to NFC Forum specifications, you must submit the required information about the product to be certified, including the Implementation Conformance Statement (ICS), test report, and test plan. In COMPRION test tools, the report can be printed, saved, and exported in various formats (for example, PDF).

3064d

NFC tags are an application of RFID technology. They are limited in their range to only a few inches or almost touching the phone to the tag. This is done deliberately, so that tags have no effect on a phone unless there is a clear user action to 'trigger' the tag. Although phones are usually touched to tags, this does not require any 'docking' or galvanic contact with the tag, so they are still considered to be a contactless technology. When an NFC-enabled phone is placed or 'tapped' on a tag, the programmed action is undertaken. This could cause a website to be displayed, the phone switched to silent mode, or many other possible actions.
