WRC-03 WRC-2000, Res. 216 resolved that WRC- 03 should examine the possibility of broadening the secondary allocation to the MSS, except AMSS to include aeronautical use Currently, the frequency band GHz is allocated to FSS, RNS, FS and MS On primary basis
WRC-03 On a secondary basis, to several other services including the MSS (except AMSS) ITU-R studies have demonstrated and concluded that appropriately designed AMSS can operate on a secondary basis without causing harmful interference to primary and secondary services
WRC-03 (Cont.) Restriction “except AMSS” was removed from the table of frequency allocation and new Recommendation was adopted by WRC-03) ITU opened the door for the commercial deployment of a new mobile information service
Recommendation 1643 This Rec. provides the technical and operational requirements for aircraft earth stations (AES) of (AMSS) in the GHz Technical guidelines includes: –Establishing conformance requirements for AES –Facilitating the licensing of AES operations
Recommendation 1643 (Cont.) –Facilitating the development of common arrangements of conformance of AES –Facilitating the development of common arrangement to enable the worldwide use of AES
Recommendation 1643 (Cont.) The following services are protected according to Rec. 1643: FSS FS RA SR
Licensing in US US Table of Frequency Allocation include: Primary allocation for: –Fixed satellite service –Radionavigation –Radio astronomy
Licensing US (Cont.) Secondary allocation for: –Mobile (except aeronautical mobile) –Space research –Fixed and mobile –Mobile-satellite service No allocation for AMSS neither in 12 or 14 GHz
Licensing US (Cont.) Boeing was given an authority to operate up to 800 technically identical transmit and receive mobile Earth stations aboard aircraft in the “14 GHz”
Licensing in Europe & Canada temporary license or authorization for Lufthansa and BA trials in: Belgium, Canada, Denmark, France, Faero islands, Germany, Greenland, Iceland, Luxembourg, Netherlands, Norway and UK
Licensing Europe (Cont.) ETSI recently developed a Standard EN for technical standard requirements of (AES)
ETSI Specify min. technical requirements of AES with both transmit and receive capabilities Frequency bands –Transmit: GHz –Receive: GHz &
ETSI (Cont.) The technical requirements divided into two major categories: –Emission limits: to protect other radio services and systems from harmful interference –AES control and monitoring functions: to protect other radio services and systems from unwanted transmission from the AES
ETSI (Cont.) The document does not cover equipment compliance with relevant civil aviation regulations AES and its installation on board aircraft are subject to additional national or international civil aviation authorities

Licensing in Jordan (Cont.) In the 14 GHz band is assigned for FS and FSS services These assignment will be protected by the system as follows: –FSS receivers: the system will protect GSO FSS satellite receivers in 14 GHz by controlling the aggregate EIRP spectral density in the direction of the GSO
Licensing Jordan (Cont.) –FS: it will comply with the PFD limits given in Rec.1643 for FS protection Based on these facts: –There will be no interference effect to services in Jordan –This service will provide two-way broadband services for planes over Jordan – Jordan be among first countries to license this service in the region
