scope:

The present document specifies the technical characteristics to be provided by TErrestrial Trunked Radio (TETRA) terminal equipment, which uses the TETRA technology. It applies to terminal equipment operating within the frequency ranges, which are expected to be allocated to TETRA when member states have implemented ERC Decision ERC/DEC/(96)/4 [18].

The objective of the present document is to ensure that no disturbance occurs to the public telecommunications network, and to ensure proper inter-working of TETRA terminals with TETRA networks so that communication can be routed successfully through the applicable network(s).

The Harmonised Standard does not contain requirements on Direct Mode operation (DMO) (which means direct interworking between two mobiles without control or intervention by a network) unless control mechanisms to avoid interference are found.

In addition to the present document, other Harmonised Standards may apply.

Requirements apply to the network interface and the Radio Frequency (RF) Air Interface of the equipment.

TETRA terminal equipment consists of several elements. The present document is structured to enable the approval of the individual elements as separate items. Because of the need for effective use of the radio spectrum, the essential air interface characteristics will always apply. For each essential requirement a test is given including measurement methods.

In the present document there are no Electromagnetic Compatibility (EMC) requirements in terms of the Terminal Directive 98/13/EC [15], article 5c.

NOTE: Technical requirements for EMC performance are covered by the relevant standards applicable to the EMC Directive 89/336/EEC [17] which also lays down the conformity assessment procedure.

The present document is based on the radio and protocol provisions of ETS 300 392 and ETS 300 394.
