General

The present document specifies technical characteristics and methods of measurements for Mobile Earth Stations 
(MES), except aeronautical mobile earth stations, which have the following characteristics: 
• The MES are operating in one or more frequency ranges, or parts thereof, of the Fixed Satellite Service (FSS): - - - 
10,70 GHz to 11,70 GHz (space to Earth); 
12,50 GHz to 12,75 GHz (space to Earth); 
14,00 GHz to 14,25 GHz (Earth to space). 
The MES is designed to transmit to the Satellite in the 14,00 GHz to 14,25 GHz band and receive from the satellite in 
the bands 10,70 GHz to 11,70 GHz and 12,50 GHz to 12,75 GHz. The MES does not cause harmful interference to 
primary services in the band (including the Fixed Satellite Service (FSS)) and does not claim protection from harmful 
interference from those services. 
• The MES may be either:  - - 
a Land Mobile Earth Station (LMES); and/or 
a Maritime Mobile Earth Station (MMES) not providing those distress and safety functions required by 
the International Maritime Organization (IMO). 
• These LMESs could be either vehicle mounted or portable equipment. 
• These MMESs are installable equipment on ships. 
• The MES could consist of a number of modules including a keyboard interface to the user. 
• The MES use linear polarization. 
• The MES operate through a geostationary satellite at least 3° away from any other geostationary satellite 
operating in the same frequency band and covering the same area. 
• The antenna of the MES may be omnidirectional or directional with a means of tracking the satellite. 
• The MES are operating as part of a satellite network used for the distribution and/or exchange of information 
between users. 
• The MES are controlled and monitored by a Network Control Facility (NCF). The NCF is outside the scope of 
the present document. 
The present document applies to the MES with its ancillary equipment and its various terrestrial ports, and when 
operated within the boundary limits of the operational environmental profile defined for its intended use and when 
installed, following the indications contained in the user documentation. 
The present document is intended to cover the provisions of Directive 2014/53/EU [i.6] (RE Directive) article 3.2, 
which states that "… radio equipment shall be so constructed that it both effectively uses and supports the efficient use 
of radio spectrum in order to avoid harmful interference". 
NOTE:  The relationship between the present document and essential requirements of article 3.2 of 
Directive 2014/53/EU [i.6] is given in Annex A.

The present document applies to cooperative communications using radio transmitters and receivers for Intelligent 
Transport Systems (ITS). ITS communications may comprise vehicle-to-vehicle, vehicle-to-infrastructure and 
infrastructure-to-vehicle.  
The equipment is comprised of a transmitter and associated encoder and modulator and/or a receiver and associated 
demodulator and decoder. The types of equipment covered by the present document are as follows: 
• OnBoard Equipment (OBE) fitted with an integral or dedicated antenna(s), intended for use in vehicles, e.g. a 
road or a rail vehicle. 
• RoadSide Equipment (RSE) fitted with an antenna socket, integral or dedicated antenna(s), normally used as a 
fixed station, e.g. a road or rail infrastructure. 
These networks operate over a short range with very wideband communications using a variety of directional medium 
and high gain antennas to enable a high degree of spectrum reuse, and may use a flexible bandwidth scheme under 
which they normally operate in a wideband mode, and periodically reduce their bandwidth (e.g. for antenna training and 
other activities). 
The technical characteristics of these applications are described in ETSI TR 102 400 [i.3], where ITS applications in the 
63,72 GHz to 65,88 GHz band is described. The present document is also in line with the results of the spectrum 
compatibility study in the CEPT ECC Report 113 [i.4]. 
These radio equipment types are capable of operating in all or any part of the frequency bands given in table 1.
