25、uency allocations of a given frequency band for the purpose of its use by one or more terrestrial or space radiocommunication services or the radio astronomy service under specific conditions NOTE: This term shall also be applied to the frequency band concerned (ITU Radio Regulations article 1, No.
26、17). Automatic Transmit Power Control (ATPC): function to offer a dynamic power control that delivers the maximum power only during deep fading activity; in this way, for most of the time, the interference is reduced and the transmitter operates in a higher linearity mode NOTE: When this function is
27、 used the transmit power is dynamically changed and follows the propagation condition. In principle when ATPC is implemented three different level of power may be identified: square4 Maximum available power (delivered only in a condition of deep fading). square4 Maximum nominal and maximum available
28、 power levels may be coincident or in case of multi-state modulation formats the maximum available power may be used to overdrive the transmitter (losing linearity but gaining fade margin when the fade conditions have already impaired the expected RBER). Performance prediction is usually made with t
29、he highest “available power“. square4 Maximum nominal power (useable on permanent base when ATPC is disabled); it should be noted that this power is “nominal for the equipment“ and has not to be confused with the “nominal level set link by link“ by the frequency co-ordination body, eventually achiev
30、ed through passive RF attenuators or RTPC function. square4 Minimum power (delivered in unfaded condition). conformity assessment procedure: See Directive 1999/5/EC 1, annexes II, III, IV and V. environmental profile: range of environmental conditions under which equipment, within the scope of the p

32、frequency band: commonly referred as a portion of the frequency spectrum that CEPT/ERC allocates to a specific service through a CEPT/ERC Decision (proper definition is currently under study by CEPT/ERC) NOTE: Presently radio frequency bands allocated to Fixed Service are not harmonized. maximum ava

ETSI ETSI EN 301 997-2 V1.1.1 (2003-09) 10radio frequency channel
36、: portion of a radio frequency band where a radio frequency channel arrangement has been established, dedicated to one fixed radio link (or a P-MP system sector) radio frequency channel arrangement: predefined centre frequencies raster for a number of radio frequency channels used by administrations
37、 for co-ordination in the same geographical area NOTE: Radio frequency channels are defined by ITU-R Recommendation F.746 20. recommended radio frequency channel arrangement: predefined centre frequencies raster for a number of radio frequency channels, covered by a CEPT/ERC Recommendation in a not
38、harmonized frequency band (not used for the same purpose by all administrations) that is recommended to the member countries in the case they use the relevant frequency band for Fixed Service NOTE: Currently, CEPT does not recommend a radio frequency channel arrangement for the 40 GHz frequency band
39、. Remote Frequency Control (RFC): function allowing to change and control the transmit/receive centre frequency/channel either by a local monitoring terminal connected to the system or a by a remote network management terminal NOTE: The frequency variation is static and usually made to adapt the fre
40、quency of the link to the interference scenario in the same geographical area. It is also used at the activation or re-commissioning of links in order to easily obtain the licensed frequency assigned by the co-ordinator body to the network operator for that link. Remote Transmit Power Control (RTPC)
41、: function allowing to change and control the transmitter output power either by a local monitoring terminal connected to the system or a by a remote network management terminal NOTE: The transmitter power variation is static and usually made at the activation or re-commissioning of links in order t
42、o easily obtain the EIRP required by the frequency co-ordination body for that link to control co-channel and adjacent channel interference in the same geographical area. In principle, this function is equivalent to the requirement of power regulation capability (e.g. by fixed attenuators) commonly
