31、chnical characteristics, exemption from individual licensing and free carriage and use of digital PMR 446 applications operating in the frequency band 446,100 MHz to 446,200 MHz. NOTE 1: The technical requirements for Digital PMR 446 included in ECC/DEC/(05)12 i.1 are: operation in the frequency ran
32、ge 446,100 MHz to 446,200 MHz, maximum e.r.p. of 500 mW, and a maximum transmitter time-out-time of 180 seconds. ii) In the frequency band 149,01875 MHz to 149,11875 MHz under exemption from individual licensing. NOTE 2: These requirements are: maximum e.r.p. of 500 mW, and a maximum transmitter tim
33、e-out-time of 180 seconds. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

39、itions For the purposes of the present document, the following terms and definitions apply: bearer service: type of telecommunication service that provides the capability for the information transfer between user network interfaces, involving only low layer functions (layers 1 to 3 of the OSI model)
40、 NOTE: Confirmed Data and Unconfirmed Data are examples of bearer services. burst: short duration RF signal that may cause interference to a dPMR transmission item call: complete sequence of related transactions between radios NOTE: Transactions may be one or more items containing specific call rela
41、ted information. Configured Services and Facilities (CSF): those functions available in the radio after re-programming Control plane (C-plane): part of the protocol stack dedicated to control and data services feature: attribute intrinsic to a station, e.g. MS has an address Handportable Station (HS
42、): physical grouping that contains all of the mobile equipment that is used to obtain dPMR mobile services and operating with an integral antenna initial services and facilities: those functions available in the radio at point of sale (out-of-the box functions) late entry: where receiving stations t
43、hat have missed the start of a transmission are able to recover all information about the call from data that is interspersed within each superframe logical channel: distinct data path between logical endpoints payload: bits in the information field peer-to-peer mode: mode of operation where radios
44、may communicate outside the control of a network NOTE: This is communication technique where any radio unit may communicate with one or more other radio units without the need for any additional equipment (e.g. BS). personalization: address and configuration information that characterizes a particul
45、ar dPMR HS NOTE: This information may be implanted by the installer before putting an HS into service. physical channel: FDMA transmission polite protocol: Listen Before Transmit (LBT) protocol NOTE: This is a medium access protocol that implements a LBT function in order to ensure that the channel
46、is free before transmitting. prefix: most significant digit of a HS address in the user domain Protocol Data Unit (PDU): unit of information consisting of protocol control information (signalling) and possibly user data exchanged between peer protocol layer entities radio frequency channel: radio fr
47、equency carrier (RF carrier) NOTE: This is a specified portion of the RF spectrum. The RF carrier separation is 6,25 kHz. Received Signal Strength Indication (RSSI): root mean squared value of the signal received at the receiver antenna signalling: exchange of information specifically concerned with
48、 the establishment and control of connections, and with management, in a telecommunication network ETSI ETSI TS 102 490 V1.8.1 (2014-06)9simplex: mode of working by which information can be transferred in both directions but not at the same time NOTE: Simplex is also known as half duplex. superframe
49、: four concatenated FDMA frames NOTE: A superframe has a length of 320 ms. supplementary service: supplementary service modifies or supplements a tele-service or bearer service NOTE: Consequently, it cannot be offered to a user as a standalone service. It is offered together with or in association with a tele-service or bearer service. The same supplementary service may be common to a number of telecommunication services. Late entry is an example of supplementary service. telecommunication service: offered by a dPMR entity in order to satisfy a specific tele
