Digitalne izboljšane brezvrvične telekomunikacije (DECT) - Brezžična relejna postaja (WRS)
Ta dokument opredeljuje brezžično relejno postajo (WRS) za digitalne izboljšane brezvrvične telekomunikacije (DECT). Brezžična relejna postaja je dodatni gradnik za fiksno omrežje digitalne izboljšane brezvrvične telekomunikacije.
Ta dokument opredeljuje določbe, ki so potrebne za nadzorovano in zanesljivo uporabo infrastrukturnega gradnika brezžične relejne postaje za digitalne izboljšane brezvrvične telekomunikacije.
Brezžična relejna postaja za digitalne izboljšane brezvrvične telekomunikacije, opredeljena v tem dokumentu, podpira profile nove generacije digitalnih izboljšanih brezvrvičnih telekomunikacij (NG-DECT) in profile ultra nizke porabe energije (ULE) digitalnih izboljšanih brezvrvičnih telekomunikacij.

1 Scope
The present document defines the Digital Enhanced Cordless Telecommunications (DECT) Wireless Relay Station
(WRS). A WRS is an additional building block for the DECT fixed network.
The present document defines provisions needed for a controlled and reliable application of the DECT WRS
infrastructure building block.
The DECT WRS defined by the present document supports the DECT New Generation (NG-DECT) and DECT Ultra
Low Energy (ULE) profiles.
