Inmarsat & Global Xpress Global Mobile Broadband Laura Roberti laura.roberti@inmarsat.com Bangkok, 19 th September 2014
Inmarsat in L-band: an overview Worldwide coverage Land, sea, and air mobile services, including safety services for maritime and aeronautical users In business since 1979 with over 100 satellite years without operational failure and 99.99% network availability Ten geostationary satellites in orbit providing simultaneous voice, data and video streaming services. 2

Market leader in MSS L-band today moving into mobile services in Ka-band Mobile Satellite Services L-band (MSS) Ka-band Global Xpress Inmarsat-4 & 6 Safety and redundancy Inmarsat-5 Core L-band services Highly mobile, agile and resilient Capacity and speed Core Ka-band services High capacity, high speed GX complements Inmarsat s L-Band network Seamless network of L-Band services, Gx services or an integrated L+GX service providing the best of both worlds. 5
Why Global Xpress? People want to use these! Broadband connectivity: anytime, anywhere 6
Mobile terminals operating in FSS frequency bands are then THE SOLUTION! GSO ESOMPs (Earth Station on Mobile Platforms) 7
Inmarsat Global Xpress Service in Ka-band (20-30GHz) Three Inmarsat-5 geostationary satellites to provide global coverage. Fourth satellite for increased capacity First successful launch on 8 th December 2013. Coverage of the Indian Ocean Region. Global service provision, with the launch of two additional satellites, in 2015 Lifetime of 15 years Complements existing L-band services. Faster data throughput. IP based. 8
Fast internet connection to small user terminals on land, at sea and in the air. Terminals similar to current VSATs in Ka-band Maritime Enterprise-Energy Aeronautical Government & Int l Organizations
So what about the rain? All Ka-band networks are impacted by rainfade So how does GX perform?
How to cope with a rainy day... Adaptive ModCod The GX system adjusts the modulation and coding scheme to use additional satellite power if available or reduce data-rate to over come rain-fade. Gateways Each satellite has 2 gateway stations (SAS) in different regions. System does auto handover between gateways to remove impact of rain fade on feeder links L-Band Backup Auto fail-over between GX services and L-Band services 11

Two Unique and Complementary Ka Payloads Global Service Beams High Capacity Overlay Global broadband access 50/5Mbps typical user throughput 89 fixed spot beams per satellite Spectrum use: 32/64MHz per beam in the following bands: User Uplink: 29.5-30.0 GHz User Downlink: 19.7-20.2 GHz Steerable beams 6 narrow beams per satellite: provide additional capacity where and when needed. Spectrum use in part of the following range: User Uplink: 29.0-29.5 GHz User Downlink: 19.2-19.7 GHz The main gateways for IOR are in Italy and Greece, for AOR in USA and Canada and, for POR, in New Zealand
Global Xpress User Terminals (ESOMPs) User terminals operate under the control of a Network Control Facility (NCF): stop transmit when - unintended satellite tracking occurs - entering an area where not authorised User terminals, from and interference perspective, are indistinguishable from other similar FSS terminals User terminals will comply with: - ITU-R Report ITU-R S.2223 - ETSI standard EN 303 978 - ECC Decision (13)01 In CEPT GX user terminals (ESOMPs ) are considered as FSS. Free circulation and exemption from individual licensing. Authorization/licensing process well under way: GX user terminals are now authorized in more than 100 countries worldwide. 14
ESOMPs and the RR Learning from the past ESOMPs are not a new concept in the Radio Regulations; Earth Stations on Vessels operate in the C- and Ku-bands; AES to operate in the FSS in the Ku-band; Both approaches are subject to certain provisions to make sure: That existing and future FSS systems are protected; That harmful interference is not caused other systems sharing the same band 15
ESOMPs Progress at the ITU ITU-R WP 4A Workshop on mobile earth stations in October 2013 set a new tone and shared technology with delegates ITU WP4A: Work on draft Recommendation essentially complete only regulatory clarification remains Radio Bureau created new official class of station in motion for Ka Earth Stations under provision 5.526. Band limitation in Region 1 and 3. Seeking action at WRC-15 to extend status available in the Americas to Europe, Africa, and Asia
The role of the Radio Regulations Facilitating new technologies, while protecting existing ones They need to evolve, to allow a flexible and efficient use of the spectrum resources. Regulations should not be an obstacle but encourage new technologies to be promptly and easily available. 17
The end! Thank you! 18
