Caller location in emergency communications (e112)

Caller location in emergency communications (e112) as a mandatory requirement for radio equipment supporting GNSS or Wireless LAN

Following EU Commission’s Delegated Regulation (EU) 2019/320, the Directive 2014/53/EU (RED) has been supplemented by additional essential requirements referenced to in Article 3(3)g. This amendment introduces new requirements for hand-held mobile equipment supporting satellite-based positioning services (GNSS) or WLAN technology.

The changes will apply from March 17 2022. From that date on, hand-held mobile devices must comply with the essential requirements of Art. 3(3) g in addition to those under Art. 3(1) and 3(2).

The baseline requirements can be clustered into three categories:

  1. Obligatory support of European satellite-based positioning system (“Galileo”) for any GNSS equipment
  2. WLAN positioning capability for devices supporting WLAN
  3. Support of Advanced Mobile Location (AML) algorithm for radio devices under 1) and 2)

As the European Standardization Organisations (ESO) refused the development of harmonized standards, conformity assessment can only be succeeded with notified body support. CE self-declaration as set out under RED Annex II is no longer allowed for this kind of equipment.

Specific assessment and test requirements to the aforementioned baseline requirements are indicated in “Guidelines for Compliance with the Delegated Regulation (EU) 2019/320”, published by the European Commission. They are structured into the following parts (A-D):

  1. Compatibility and interoperability with the Galileo system
  2. Availability of GNSS raw measurements
  3. Processing and making available for transmission of the data referred to in Article 1(2) of Delegated Regulation (EU) 2019/320
  4. Use of a wireless local area network for positioning

Tests are mainly based on existing ETSI test standards and test specifications like EN 303 413, TS 103 246 and TS 103 625. In this way, the underlying test methods are clearly described and approved.

We are well prepared to support our customers in fulfilling these new requirements. Our specialists are ready to assist in mapping the requirements to specific devices, creating test plans and accompany the certification process carried out by our RED notified body.
