General

The present document specifies technical characteristics and methods of measurements for equipment implementing the 
Digital Enhanced Cordless Telecommunications (DECT) common interface, as specified in the multi-part technical 
specification ETSI EN 300 175 including the variants DECT Evolution and DECT ULE (see ETSI EN 300 175-1 [i.3] 
for an overview). 
The present document applies to the following equipment types: 
a) Fixed Part (FP); 
b) Portable Part (PP); 
c) Cordless Terminal Adapter (CTA); 
d) Wireless Relay Station (WRS) (FP and PP combined); 
e) Hybrid Part (HyP) (a PP with capability to act as a FP to provide PP to PP communication). 
NOTE: This release of the standard covers the WRS type CRFP, but not the WRS type REP. 
These radio equipment types are capable of operating in all or any part of the frequency bands given in table 1. 
Table 1: Radiocommunications service frequency bands 
 Radiocommunications service 
frequency bands
Transmit 1 880 MHz to 1 900 MHz 
Receive 1 880 MHz to 1 900 MHz 
The DECT service frequency band for transmitting and receiving for all elements is 1 880 MHz to 1 900 MHz. 
National regulation can allow additional frequency bands. 
Details of the DECT Common Interface may be found in the multi-part deliverable ETSI EN 300 175 (see [1] to [4] and 
[i.3] to [i.6]). Further details of the DECT system may be found in the ETSI TR 101 178 [i.1]. 
DECT ULE implements, in addition to the DECT Common Interface, the multi-part ETSI TS 102 939 (see ETSI 
TS 102 939-1 [i.7] and ETSI TS 102 939-2 [i.8]). 
The present document contains requirements to demonstrate that radio equipment both effectively uses and supports the 
efficient use of radio spectrum in order to avoid harmful interference. 
NOTE: The relationship between the present document and essential requirements of article 3.2 of 
Directive 2014/53/EU [i.10] is given in annex A.

The present document is a specification of the lower layers and the lower layer signalling system for the two-way 
satellite network variants defined by ETSI TS 101 545-3 [i.16]. The present document constitutes a complete 
specification of the lower layers for a transparent star satellite network, a transparent mesh overlay satellite network and 
a regenerative re-multiplexing satellite network. Also, components required for a satellite network with a TRANSEC 
system are included. 
The present document is normative for the consumer terminal profile in a transparent star satellite network as defined 
by ETSI TS 101 545-3 [i.16], and does also include normative components specific to the other terminal profiles and 
satellite network variants defined by ETSI TS 101 545-3 [i.16].
