1 Scope
The present document specifies the minimum performance requirements for terrestrial fixed service
radiocommunications equipment operating in the 58 GHz frequency band which do not require co-ordinated frequency
planning.
The frequency band is proposed to be used by various technologies for uncoordinated use of the band. It also benefits
from the high and stable atmospheric attenuation which suppresses efficiently distant interferers (about 10 to 15 dB/km
at sea level, refer to ITU-R Recommendation P.676 [16]).
For the purposes of the present document two equipment Classes are specified depending on the network requirements:
- Class A: Digital equipment for High Density Fixed Service (HDFS) applications typically connected to public
networks, which apply the RF-channel selection procedure (see subclause 4.1.3), error performance and
availability requirements (see subclause 5.2).
- Class B: Equipment without requirements for quality of service, typically private network connections.
Typical applications for Class A equipment are e.g. interconnection between cellular networks where there, in some
cases, is a need for short length connections (up to about 500 meters). The RF channel selection procedure shall be used
to protect existing systems from a new system being commissioned. However, the channel selection procedure may not
guarantee interference free installation or operation in all cases due to limitations in the procedure with respect to the
variety of systems.
Typical applications for Class B equipment are in private networks, such as video surveillance systems.
The present document does not contain aspects related to test procedures and test conditions, however they are to be
found in EN 301 126-1 [6].
Safety aspects are outside the mandate of ETSI and they will not be considered in the present document. However
compliance to CENELEC EN 60950 [17] will be required to comply with 99/5/EC [18] Directive (R&TTE).
Technical background for the parameters and requirements referred in the present document may be found in
TR 101 036-1 [15].

4 General characteristics
4.1 Frequency bands and channel arrangements
4.1.1 Frequency band
The frequency band is from 57 GHz to 59 GHz.
NOTE: The successful co-existence of Class A and Class B equipment may require the regulator to define
exclusive spectrum for each equipment Class (see annex A).
4.1.2 Radio Channel Arrangements
The channel arrangements are specified in CEPT/ERC Recommendation 12-09 [5] with 50 MHz or 100 MHz channel
rasters. For reader convenience, the basic parameters of the CEPT Recommendation are shown in informative annex A.
4.1.3 RF-channel Selection
RF-channel selection procedure is mandatory for Class A equipment only.
4.1.3.1 RF-channel selection procedure
The purpose of the RF-channel selection procedure is to detect and protect existing transmissions in order to avoid
unacceptable interference situations.
At both transmission sites, radio-relay terminals shall measure during installation, the interference levels of both receive
and transmit channels (Note). Only in the instance when an unoccupied channel is identified and selected as the
transmission channel shall the transmit power be switched on. The interference avoidance requirements for the receiver
to detect occupied channels are specified in subclause 4.1.3.2 below.

9 ETSI EN 300 408 V1.2.1 (2000-09)
The principle of protecting existing transmission shall be respected also during the antenna alignment (see annex A for
examples of possible antenna alignment procedures)
NOTE: If the national regulatory rules allowes to change the frequency of the link during its operation, it may be
considered, in order to decrease the possibility of undete
