4 Technology and Performances
4.1 Brief Description of the Adaptive Kernel Tag Technology
The Adaptive Kernel Tag approach consists of two components:
 A low cost, universal and world smallest UHF “Kernel” module converted into the package
 An adaptive antenna, which is customized and intrinsically incorporated within the package of
the item to be RFID-enabled, and also placed in close proximity to the Kernel Tag
A reader sends a radio signal at a specific UHF frequency range via an antenna linked to a reader.
This radio signal activates the AK tag which sends its data to the reader. The reader decodes the
AK tag data and sends this decoded data to a host PC for processing. This radio signal is also
used to write data to the AK tag.
 Alone the AK Tag module can be read/write at a distance up to 30cm(12 inches) according to
the antenna reader characteristics
 AK Tag module associated to the adaptive antenna can be read/write at a distance up to 4m
(13 feet) depending on the item where they are affixed and the size of the secondary antenna.
4.2 AK Tag Read/Write Performances
The AK Tag concept is universal. The Kernel tag can therefore be used for a multitude of items, all
different in size, shape and material. The performance of the Kernel tag can be adapted to its
environment: the geographic region of tag operation or the read range requirements for the object,
by the use of a secondary Adaptive antenna.
The table below shows read/write performances of items equipped with the AK Tag.
These performances have been measured with the 1 Watt SIRIT/TAGSYS Reader.
Items Read/Write distance performances
A standard courier envelope ≤ 3.5m (11.50ft)
A standard luggage label ≤ 4.0m (13.00ft)
A fashion price tag ≤ 1.5m (4.90ft)
A box ≤ 4.0m (9.80ft)
4.3 Tag Encoding
Due to its small size the AK Tag Module requires a small UHF antenna to be correctly encoded.
If you do not own a small UHF antenna we recommend you the AK Tag Module Booster to
facilitate the encoding using a standard UHF antenna reader.
1. Place the AK Tag Module Booster on the SIRIT/TAGSYS reader
2. Place the AK Tag Module on the AK Tag Module Booster as shown Figure 7
3. Proceed to encoding operation
