The present document specifies technical characteristics and methods of measurements for the following equipment types (which are parts of a Mobile Communication On Board Aircraft system): 1) The Onboard Base Transceiver Station (OBTS) supporting GSM and/or UMTS, and/or LTE communication protocols including specific functions for restricting the transmit power of the MSs or UEs, associated with the OBTS. 2) The Network Control Unit (NCU) preventing direct connection of the onboard mobile terminals with mobile networks on the ground by raising the noise floor in the cabin. The OBTSs are capable of operating in all or any part of the frequency bands given in table 1-1. Table 1-1: Base Station operating bands Band designation; Direction of transmission Base Station operating bands UTRA I; BS Transmit 2 110 MHz to 2 170 MHz (UMTS); BS Receive 1 920 MHz to 1 980 MHz (UMTS) E-UTRA 3; BS Transmit 1 805 MHz to 1 880 MHz (LTE); BS Receive 1 710 MHz to 1 785 MHz (LTE) DCS 1800; BS Transmit 1 805 MHz to 1 880 MHz (GSM); BS Receive 1 710 MHz to 1 785 MHz (GSM) The NCU is capable of operating in all of the frequency bands given in table 1-2. Table 1-2: NCU operating bands NCU operating bands; Comment 460 MHz to 470 MHz (see note) 791 MHz to 821 MHz (see note); LTE 925 MHz to 960; MHz GSM 1 805 MHz to 1 880 MHz (see note); GSM/LTE 2 110 MHz to 2 170 MHz; UMTS 2 570 MHz to 2 620 MHz (see note); LTE 2 620 MHz to 2 690 MHz (see note); LTE NOTE: Implementation of this operating band in a NCU is not mandatory according to the EC Decision 2016/2317/EU. The present document applies only to radio equipment using a dedicated transmitting antenna that is designed as an indispensable part of the system for usage on board an aircraft. It applies to equipment for continuous and discontinuous transmission of data and digital speech. Within the European Union, the system covered by the present document operates in accordance with the operational requirements as outlined in the Commission Decision 2016/2317/EU based on the former Decision 2013/654. In relation the NCU, some frequency bands are now optional while they were mandatory before. Due to this difference the present document had to be reviewed. The present document contains requirements to ensure that such Radio equipment both effectively uses and supports the efficient use of radio spectrum in order to avoid harmful interference. In addition to the present document, other ENs that specify technical requirements in respect of essential requirements under other parts of article 3 of the Radio Equipment Directive may apply to equipment within the scope of the present document. The present document does not cover equipment compliance with relevant civil aviation regulations. In this respect, a MCOBA system, for its installation and operation on board an aircraft is subject to additional national or international civil aviation airworthiness certification requirements, for example to EUROCAE ED-14G. NOTE: The relationship between the present document and essential requirements of article 3.2 of Directive 2014/53/EU is given in annex A
