3. www.gvf.org Wi-MAX Spectrum by Region 2005 - 2007 Spectrum Focus 2.3, 2.5, 3.5, 5.8 GHz 2.3, 2.5, 3.7, 5.8 GHz 2.5, 3.5, 5.8 GHz 2.5, 3.5, 5.8 GHz 3.5, 5.8 GHz 2.3, 2.5, 3.5, 5.8 GHz 2.3, 2.5, 3.3, 3.5, 5.8 GHz Expect future WiMAX deployments in spectrum ~ 700 MHz Expect future WiMAX deployments in spectrum ~ 700 MHz A key issue is Europe, especially the 2.5GHz Band North America Caribbean & Latin America Middle East & Africa Asia Pacific Source: Wi-MAX Forum Presentation Delivered at 2007 GVF C-band Summit

4. www.gvf.org IMT/Wi-MAX in C-band Downlinks Band commonly used by FSS satellites Additional band (FSS, feederlinks for MSS, …) Future mobile phone networks (IMT Advanced, 4G, ….) Broadband Wireless Access (BWA), WiMax, FWA, …. Was recently considered at ITU WRC-07 Is currently being introduced country by country worldwide 3.43.53.63.73.83.9 4.0 4.14.2 Std. C Etx. C

5. www.gvf.org The Findings BWA or IMT in a part or all of the FSS C-band downlink will be incompatible with general FSS reception in any part of C-band in the same geographical area BWA or IMT in a part of C-band may be compatible with FSS reception by a small number of earth stations if: –Appropriate exclusion zones around each of the earth stations are established –User terminals are designed not to emit any signals when not in contact with a base station Introduction of BWA or IMT by one country can block FSS reception in another country

6. www.gvf.org Why Is SatCom Important in C-band?

7. www.gvf.org Exclusion Zones: A Viable Solution? Example of calculated exclusion zone around an earth station to counter interference from a single IMT base station in each cell (From French study to ITU Working Party 8F (Document WP 8F/868))

8. www.gvf.org Impact of protection of earth stations in non-overlapping frequency bands (e.g. BWA in 3.5 GHz and FSS in 3.7-4.2 GHz) ATLAS OF THE WORLD.. 2 km exclusion zones around one earth station at the White House and one earth station at the Pentagon (protection against micro- cell base station used in urban areas)

9. www.gvf.org USE OF 3625 – 4200 MHz BY THE FSS IN BRAZIL Brazilian Contribution at June CITEL Meeting (OEA/Ser.L/XVII.4.2 CCP.II-RADIO/doc. 974/06):  No Better Band to Address Rain Attenuation  Exclusion Zones Unworkable in Nations with High-Density Satcom Deployment  Developing Countries Can’t Afford Equipment Changeout Conclusion: 3625-4200 & 4500 – 4800 MHz Should Not Be Considered for IMT

13. www.gvf.org The WRC-07 Outcome: Agenda Item 1.4 No global identification for IMT, But… Individual countries can take a different position to the international community and sign up to ‘country footnotes’ that offer… –In Region 1: 3 400 – 3 600 MHz is allocated to mobile services and identified for IMT for some countries –In Region 2: 3 400 – 3 500 MHz is allocated to mobile services –In Region 3: 3 400 – 3 500 MHz is allocated to mobile services and identified for IMT for some countries, as is 3 500 – 3 600 MHz

14. www.gvf.org

15. How C-band Will be ‘Protected’ Any deployment of IMT services in the C band must fulfil strict criteria laid out in the country footnote: –Careful limits are placed on the power flux density allowed at the border between countries that choose to allow the deployment of IMT services and countries that follow the norm –Existing rules governing sharing between services are reaffirmed to make sure they are applied when necessary - to help protect both existing and future satellite services There are no future agenda items to revisit this issue in the years to come; case closed…

16. www.gvf.org … With Some ‘Small’ Caveats WRC-07 Protections Focus on Cross-Border Protections National-Level Interference Still Major Issue At WRC-07 only 200 MHz allocated to IMT in C-Band IMT Sector Wants More… Americas: Brazil at CITEL PCC.II, Mexico, Colombia, others Arab Region: Jordan at ATRN Europe: EC Dismisses Satellite Industry Recommendations Asia: Australia, India, Mongolia, others Africa: More Than 50 Wi-MAX Licenses Issued by 2007; Major Interference Being Reported Across Continent GVF Has Now Launched The ‘Spectrum Security Initiative’
