Elektromagnetna združljivost in zadeve v zvezi z radijskim spektrom (ERM) - Naprave kratkega dosega (SRD) - Radijska oprema, ki se uporablja v frekvenčnem območju od 40 GHz do 246 GHz - 1. del: Tehnične karakteristike in preskusne metode
Ta dokument velja za naslednje glavne vrste opreme naprav kratkega dosega:
• splošne naprave kratkega dosega, vključno z alarmi, telekomando, telemetrijo, splošni prenos podatkov itd.
Te vrste radijske opreme so zmožne delovati v dovoljeni frekvenčnih pasovih v razponu od 40 GHz do 246 GHz, kot je določen v preglednici 1:
• bodisi s povezavo z radiofrekvenčnim (RF) izhodom in namensko anteno bodisi z vgrajeno anteno;
• za vse vrste modulacij.
Preglednica 1 prikazuje seznam frekvenčnih pasov, kot je določeno v priporočilu CEPT/ERC 70-03 [i.1], znanim na datum objave tega dokumenta.
OPOMBA 1: Preglednica 1 predstavlja najbolj splošno izvedeno postavko v državah članicah CEPT [i.1], vendar se ne sme predpostavljati, da so vsi opredeljeni pasovi na voljo v vseh državah. Prav tako se predvideva, da se lahko te frekvence uporabijo v točkah [i.2], [i.3] in [i.4] v prihodnosti.
OPOMBA 2: Poleg tega je trebe opozoriti, da so napravam kratkega dosega v razponu od 40 GHz do 246 GHz, ki ga zajema ta dokument, lahko na voljo drugi frekvenčni pasovi v državi. Glej priporočilo CEPT/ERC 70-03 [i.1], kot se izvaja z državnimi radijskimi vmesniki (NRI) ali dodatnimi NRI, kjer je ustrezno.
OPOMBA 3: Na neharmoniziranih parametrih lahko državni upravni organi naložijo nekatere pogoje, kot so na primer vrsta modulacije, frekvenca, ločevanje kanala/frekvence, največja moč oddajanja oddajnika, obratovalni cikel in vključitev avtomatskih naprav za izklop oddajnikov, ki se zahtevajo za izdajo individualnih pravic za uporabo spektra ali za splošno avtorizacijo ali uporabo z »licenčno izjemo«, kot velja večinoma za naprave kratkega dosega.
Ta dokument zajema stalne, mobilne in prenosne postaje.

ETSI ETSI EN 305 550-1 V1.1.1 (2011-07) 6 1 Scope The present document applies to the following Short Range Device major equipment types: • Generic Short Range Devices, including alarms, telecommand, telemetry, data transmission in general, etc. These radio equipment types are capable of operating in frequency bands within the 40 GHz to 246 GHz range as specified in table 1: • either with a Radio Frequency (RF) output connection and dedicated antenna or with an integral antenna; • for all types of modulation. Table 1 shows a list of the frequency bands as designated in the CEPT/ERC Recommendation 70-03 [i.1] as known at the date of publication of the present document. NOTE 1: Table 1 represents the most widely implemented position within the CEPT countries [i.1], but it should not be assumed that all designated bands are available in all countries. It is also foreseen that these frequencies may be implemented in [i.2], [i.3] and [i.4] in the future. Table 1: Short Range Devices within the 40 GHz to 246 GHz frequency range Frequency Bands (Transmit and Receive) Applications Notes 57 GHz to 66 GHz Non-specific SRD CEPT-ECC and European Commission regulatory implementation is under discussion
61,0 GHz to 61,5 GHz Non-specific SRD
122 GHz to 123 GHz Non-specific SRD
244 GHz to 246 GHz Non-specific SRD
NOTE 2: In addition, it should be noted that other frequency bands may be available for short range devices in a country within the frequency range 40 GHz to 246 GHz covered by the present document. See the CEPT/ERC Recommendation 70-03 [i.1] or as implemented through National Radio Interfaces (NRI) and additional NRI as relevant. NOTE 3: On non-harmonized parameters, national administrations may impose certain conditions such as the type of modulation, frequency, channel/frequency separations, maximum transmitter radiated power, duty cycle, and the inclusion of an automatic transmitter shut-off facility, as a condition for the issue of an individual or general licence, or as a condition for the issuing of Individual Rights for use of spectrum or General Authorization, or as a condition for use "under licence exemption" as it is in most cases for Short Range Devices. The present document covers fixed stations, mobile stations and portable stations. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

1 Scope
The present document applies to the following Short Range Device major equipment types:
• Generic Short Range Devices, including alarms, telecommand, telemetry, data transmission in general, etc.
These radio equipment types are capable of operating in frequency bands within the 40 GHz to 246 GHz range as
specified in table 1:
• either with a Radio Frequency (RF) output connection and dedicated antenna or with an integral antenna;
• for all types of modulation.
Table 1 shows a list of the frequency bands as designated in the CEPT/ERC Recommendation 70-03 [i.1] as known at
the date of publication of the present document.
NOTE 1: Table 1 represents the most widely implemented position within the CEPT countries [i.1], but it should
not be assumed that all designated bands are available in all countries. It is also foreseen that these
frequencies may be implemented in [i.3], [i.4], [i.5] in the future.

61,0 GHz to 61,5 GHz Non-specific SRD
122 GHz to 123 GHz Non-specific SRD
244 GHz to 246 GHz Non-specific SRD
NOTE 2: In addition, it should be noted that other frequency bands may be available for short range devices in a
country within the frequency range 40 GHz to 246 GHz covered by the present document. See the
CEPT/ERC Recommendation 70-03 [i.1] or as implemented through National Radio Interfaces (NRI) and
additional NRI as relevant.
NOTE 3: On non-harmonized parameters, national administrations may impose certain conditions such as the type
of modulation, frequency, channel/frequency separations, maximum transmitter radiated power, duty
cycle, and the inclusion of an automatic transmitter shut-off facility, as a condition for the issue of an
individual or general licence, or as a condition for the issuing of Individual Rights for use of spectrum or
General Authorization, or as a condition for use "under licence exemption" as it is in most cases for Short
Range Devices.
The present document covers fixed stations, mobile stations and portable stations.

3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
alarm: use of radio communication for indicating an alarm condition at a distant location
artificial antenna: non-radiating dummy load equal to the nominal impedance specified by the provider
assigned frequency band: frequency band within which the device is authorized to operate and to perform the intended
function of the equipment
Direct Sequence Spread Spectrum (DSSS): form of modulation where a combination of data to be transmitted and a
fixed code sequence (chip sequence) is used to directly modulate a carrier, e.g. by phase shift keying
NOTE: The code rate determines the occupied bandwidth.
dedicated antenna: removable antenna supplied and tested with the radio equipment, designed as an indispensable part
of the equipment
fixed station: equipment intended for use in a fixed location
Frequency Hopping Spread Spectrum (FHSS): spread spectrum technique in which the transmitter signal occupies a
number of frequencies in time, each for some period of time, referred to as the dwell time
NOTE: Transmitter and receiver follow the same frequency hop pattern. The number of hop positions and the
bandwidth per hop position determine the occupied bandwidth.
integral antenna: permanent fixed antenna, which may be built-in, designed as an indispensable part of the equipment
mobile station: equipment normally fixed in a vehicle or used as a transportable station
necessary bandwidth: width of the emitted frequency band which is just sufficient to ensure the transmission of
information at the rate and with the quality required under specified conditions
NOTE: The necessary bandwidth including the frequency tolerances is accommodated within the assigned
frequency band.
occupied bandwidth: width of a frequency band such that, below the lower and above the upper frequency limits, the
mean powers emitted are each equal to 0,5 % of the total mean power of a given emission
NOTE: This corresponds to the -23 dBc bandwidth of the signal.
operating frequency: nominal frequency at which equipment is operated; this is also referred to as the operating centre
frequency
NOTE: Equipment may be able to operate at more than one operating frequency.
operating frequency range: range of operating frequencies over which the equipment can be adjusted through tuning,
switching or reprogramming
portable station: equipment intended to be carried, attached or implanted
radiated measurements: measurements which involve the absolute measurement of a radiated field
spread spectrum: modulation technique in which the energy of a transmitted signal is spread throughout a large
portion of the frequency spectrum
unwanted emissions: emission on a frequency or frequencies which are outside the necessary bandwidth and the level
of which may be reduced without affecting the corresponding transmission of information
NOTE: Unwanted emissions include harmonic emissions, parasitic emissions, intermodulation products and
frequency conversion products.

fixed station: equipment intended for use in a fixed location
Frequency Hopping Spread Spectrum (FHSS): spread spectrum technique in which the transmitter signal occupies a
number of frequencies in time, each for some period of time, referred to as the dwell time
NOTE: Transmitter and receiver follow the same frequency hop pattern. The number of hop positions and the
bandwidth per hop position determine the occupied bandwidth.
integral antenna: permanent fixed antenna, which may be built-in, designed as an indispensable part of the equipment
mobile station: equipment normally fixed in a vehicle or used as a transportable station
necessary bandwidth: width of the emitted frequency band which is just sufficient to ensure the transmission of
information at the rate and with the quality required under specified conditions
NOTE: The necessary bandwidth including the frequency tolerances is accommodated within the assigned
frequency band.
occupied bandwidth: width of a frequency band such that, below the lower and above the upper frequency limits, the
mean powers emitted are each equal to 0,5 % of the total mean power of a given emission
NOTE: This corresponds to the -23 dBc bandwidth of the signal.
operating frequency: nominal frequency at which equipm
