3 Agenda 1.1 for the 2015 Conference AI 1.1 Terrestrial Mobile broadband : Genesis: Res 233 (WRC-12) calls for studies on (a) additional spectrum requirements for IMT and (b) potential candidate frequency bands Key claim: growth in use of IMT systems demands more spectrum However, questions remain unanswered by the mobile industry ESOA Objective: Ensure protection of satellite services in , MHz, MHz and MHz 3

4 Satellite C-band is alive and well C-band supports critical satellite services that need high availability C-band is used by satellites globally to support a range of communications services, especially in climatically challenged regions (subtropical convergent zone). Satellite industry has made and is continuing to make extensive investments in C-band : In addition to the more than 169 C- band satellites in orbit, 35+ satellites constructed/scheduled to be launched in , representing $9-10 billion infrastructure investment Numerous national satellite programs have launched or are in development Graphic: C-Band Earth Stations in Africa ( MHz) (Incomplete Count from Intelsat) 4

5 Satellite C-band services are *not* replacable C-band services are irreplaceable due to its unique characteristics: superior availability and wide coverage: Ku and Ka band cannot provide the high availability demanded of services Studies submitted by GSMA indicating that many services can be supported by Ku band are not credible Such claims rely on an untenable availability and coverage assumptions based on a limited set of service types that are not representative Customers and users of C-band satellite know what they need, and know that other bands *cannot* meet their requirements. 5

6 Africa Europe! Africa has its own characteristics Not only because of its unique tropical climatic regions, But also to its size. The territory of all of Europe is on the scale of a single country in Africa. Key users continue to have requirements which only satellite C-band can satisfy Needed where outage is not acceptable Demand remains high, and C-band is heavily used.. 6

8 IMT So what about IMT? The satellite industry does not contest the legitimate needs of the IMT industry to grow without undue spectrum constraints Satellite and terrestrial mobile services are complementary and their co-existence drives mutual growth. One obvious case in point is that satellite C-band provides for terrestrial mobile backhaul in many regions But: The growth IMT does not depend on a global identification for IMT in the bands currently used for critical and irreplaceable satellite services! 8

9 IMT spectrum predictions IMT will not require the amount of spectrum they are asking for under this agenda item. Future demand is contested with multiple sources indicating that it is over-stated An LS Telecom report of August 2014 concluded the results of the model developed by the ITU WP-5D for forecasting mobile demand is built upon a faulty set of inputs, for example regarding traffic density figures which are: are at least two orders of magnitude [i.e. 100 times] too high when compared with those which would be expected in any developed or developing country in a 2020 timeframe Small cell and WiFi offload effects have not been factored in to calculations Other studies have shown similar results, and we see a repeating pattern: WiMAX customers were approx. 1M subscribers in 2007 compared to some 15M+ average of 15 forecasts The ITU WP-5D forecast spectrum requirements for IMT in 2015 is 2 to 3 times higher than that which is actually licensed and in use 9

10 IMT spectrum needs Mobile industry has not demonstrated a need for this spectrum Spectrum currently identified for IMT is significantly under-utilised (<50%) Many countries have not made available spectrum identified for IMT in 2007 If identified spectrum is not licensed to IMT, then the first action should be to implement the mechanisms to license it. IMT can still grow and serve Africa with existing spectrum - let s start by licensing it and using it 10

11 IMT and FSS simply cannot coexist ITU studies Studies have consistently concluded that protection distances of between km are necessary to allow co-frequency sharing between BWA/IMT systems and FSS earth stations, i.e. co-coverage sharing is not feasible Adjacent band protection distances to avoid LNB overload of FSS receivers are between km Considering that a typical city has a radius of 15 to 30 km, sharing between BWA/IMT systems and FSS receive earth stations is not realistic Reconfirmed in the current CEPT Brief on AI 1.1): Report ITU-R M.2109 have demonstrated that there is no technical compatibility between the FSS and MS operation in the same geographical area Considering the studies conducted by the JTG for IMT [for the WRC 15 cycle], the new IMT parameters do not change the overall conclusion of the existing studies 11

12 The sharing myth It s easy for the IMT community to promote sharing. when the services of party promoting the sharing is never effected by the operations of services with which they are asking to share! This is simple physics, a result of the extreme power disparity of transmitting signal of the satellite downlink vs the terrestrial mobile service As such, implementing provisions for protecting existing satellite terminals does not provide for a fair or symmetric co-existence of FSS and IMT services. Rather, this would be a choice to re-assign currently used satellite spectrum to terrestrial mobile services. 12

13 L-band L-band services also need protection: There are IMT candidate bands in & MHz ITU-R studies concluded that co-frequency sharing between BSS and IMT in MHz is not feasible in the same area There is potential for interference from IMT in MHz into BSS operating in MHz. There is potential for interference from IMT into MSS operating above 1518 MHz Studies on these issues were not completed by the ITU-R To protect L-band satellite services: The band MHz should not be identified for IMT unless measures are taken to ensure the protection of BSS operating in MHz and the MSS operating in MHz The consideration of identification of IMT in the band MHz shall not impose any limitation to the incumbent BSS(sound) operating under primary allocation in this band. The band MHz is not feasible to be considered as the potential candidate bands for IMT system under WRC-15 agenda item

14 Interference and protection AI 9.1-5: RESOLUTION 154 (COM6/24)-WRC-12 Consideration of technical and regulatory actions in order to support existing and future operation of fixed-satellite service earth stations within the band MHz, as an aid to the safe operation of aircraft and reliable distribution of meteorological information in some countries in Region 1 Tendency of some within the ITU community is to consider that the ask of Res. 154 is currently satisfied by existing provisions of Radio Regulations Reality is different, as in practice interference from terrestrial mobile services does, and continues to happen. Despite the existing general provisions of the Radio Regulation Despite the protection safeguards built into the C-band footnote identifying IMT in GHz in some countries Examples of interference from WiMaX and other mobile terrestrial services operating in GHz are present and increasing throughout the world, including in Africa. 14

15 Conclusions The satellite industry opposes identification of satellite spectrum in C-band (and L-band) for IMT: These satellite bands are essential to ensure availability of critical services Mobile industry has not demonstrated a need for this spectrum Current identified IMT bands are significantly under-used Satellite and mobile services cannot co-exist 15
