Update on EN 302 208

RFID manufacturers and system integrators with equipment operating at UHF should familiarise themselves with two developments concerning the ETSI standard EN 302 208.

Firstly version v1.1.2 of this standard will be superseded at the end of 2009. This means that it will no longer be possible under the standard to place on the European market product using LBT and operating across 10 high power channels. From 1 January 2010 all new equipment should comply with v1.2.1 of the standard, which describes the use of the four-channel plan as the accepted mitigation technique.

Further revisions to the standard have recently been approved and will be published in the Spring and harmonised in late 2010. The new version of the standard is v1.3.1. The principal changes are as follows

  1. The extreme temperature limits in clause 5.4.1 have been amended to bring the requirements for Category III equipment in line with other ETSI standards. In addition manufacturers may specify alternative temperature ranges to those in Table 1.
  2. The maximum permitted horizontal beamwidths for antennas connected to interrogators have been revised. Clause 8.3.3. introduces an intermediate limit at 1 W e.r.p. of +/- 90 deg. By extension the limit for horizontal beamwidth at 2 W e.r.p. has been amended to +/- 45 degrees.
  3. The test methods for measurement of the spectrum mask (clause 8.4) and spurious emissions (clause 8.5) have been revised. The new test methods ensure that any unacceptable emissions at the start and end of a transmission are detected. As a consequence of this change it was decided to improve the text in clause 6.4.1, which describes “Normal test signals for data”.
  4. The test procedure for tags in clause 10 has been re-written to align it with the requirements of ERC Rec 74-01. The new test method requires firstly measurement of the radiated power transmitted by a tag and secondly measurement of its unwanted emissions outside its necessary band.
  5. The settings specified for the RBW and the VBW for the spectrum analyser in clauses 8.4, 8.5, 10.1 and 10.2 have been revised.
