800 MHz Reconfiguration

1. 800 MHz Reconfiguration Region 39 Presentation Nashville, TN September 15, 2005

2. History • Interference first identified in late 1990s • Nextel worked with public safety and FCC to develop “Best Practices” for resolving 800 MHz interference reactively • In 2001, Nextel filed a “White Paper” with FCC to eliminate interference proactively • Nextel joined with public safety and private wireless carriers in 2002 to create the “Consensus Plan” • Intense opposition and lobbying occurred during 2003 and 2004 • FCC issued a decision in August of 2004 • Revised decision was issued in December of 2004 • Nextel accepted responsibilities & obligations on February 7, 2005 • Nextel commences 800 MHz reconfiguration on June 27, 2005 Nashville September 15, 2005

9. Requirements Reconfiguration Principles • Sprint Nextel must have “Phase I” complete in 20 markets within 18 months (mid-2006) • Entire nation must be fully complete within 36 months (except border regions) • Licensees will have all reasonable costs of reconfiguration paid for by Sprint Nextel • Sprint Nextel (and other cellular carriers) must adopt more stringent interference protection standards immediately Key Objectives • Minimize disruption to public safety communications systems during reconfiguration Nashville September 15, 2005

12. How we all can get it done Reconfiguration Sequence • Transition Administrator releases frequency plans • Sprint Nextel initiates negotiations with licensees • Sprint Nextel and licensee execute Frequency Reconfiguration Agreement • Sprint Nextel pays all reasonable costs associated with reconfiguration Typical Reconfiguration Steps • Sprint Nextel’s replacement channels added to Licensee’s call sign • Licensee has both “old” and “new”channels on their license • Sprint Nextel discontinues use of replacement channels • Licensee uses replacement channels for reconfiguration • Retune mobiles, portables and repeaters to utilize “new” channels • Licensee discontinues use of its original “old” channels • Licensee cancels “old” channels from their FCC license Nashville September 15, 2005

13. Guard band elections (860’s) • The 800 MHz Order of the Federal Communications Commission (“FCC”) envisions that Public Safety entities currently operating in the Expansion Band (815-816 MHz/860-861 MHz) will be relocated unless they affirmatively elect to remain in the Expansion Band • Costs of Public Safety licensees relocating out of the Expansion Band will be paid by Sprint Nextel • Generally, if a licensee does not also have frequencies in the 806-809MHz/851-854 MHz range that must be reconfigured in the near term, they should negotiate and reconfigure in the same timeframe as licensees with NPSPAC frequencies (821-824 MHz/866-869 MHz) Nashville September 15, 2005

14. Negotiations with licensees • Affected licensees must enter into an agreement with Sprint Nextel before reconfiguration can begin • Sprint Nextel has already begun voluntary negotiations with licensees • Per FCC requirements, Sprint Nextel will proceed in this order for each wave: PHASE I Move non-Sprint Nextel, non-Southern LINC channels 1-120 PHASE II Relocate NPSPAC licensees currently in 866-869 MHz band and public safety who elect to move out of the 860-861 MHz expansion band. Nashville September 15, 2005

15. Preparing for negotiations • Validate accuracy of your FCC licenses • Assemble reconfiguration team & identify/authorize a representative to consult with Sprint Nextel • Contact your Sprint Nextel representative • Inventory radio equipment: Make and Model (not serial #) • Number of mobile units • Number of combiners • Number of repeaters • Number of base stations • Identify call signs and frequencies to be reconfigured • Develop a detailed list of what needs to be changed • Identify other agencies that interoperate with your system • Prepare a preferred work schedule, including times of day to minimize disruption Nashville September 15, 2005

16. Sprint Nextel’s commitment • Sprint Nextel, formed by the combination of Sprint Corporation and Nextel Communications, assumes and will honor all obligations that Nextel accepted to implement the FCC’s 800 MHz reconfiguration plan • We’re committed to a timely and efficient reconfiguration of the 800 MHz band • We’ll work closely with licensees from negotiating reconfiguration agreements through retuning the last public safety radio • We’ll work to minimize disruption to public safety communications systems during reconfiguration • The overriding goal: eliminate CMRS interference to public safety radios at 800 MHz Nashville September 15, 2005

17. Typical questions • Who pays for reconfiguration? • Who handles the paperwork with FCC? • Can we do the work ourselves? • Is there anything written for us to review? • Can Sprint Nextel pay the vendors directly? • Are dollars available for system upgrades? • How will I get my new frequencies? • Others?
