3. History of the 800 MHz Band • Established in the 1970s for land mobile use (reallocated from UHF-TV) • Intended to relieve crowding of lower band land mobile frequencies • Channels allocated for mixture of services • Public Safety • Business Radio • Industrial/Land Transportation (e.g., utilities) • Specialized Mobile Radio (commercial service)

6. Interference Problem • Mid-1990s – Nextel and other commercial providers begin deploy cellular-architecture systems in and adjacent to the 800 MHz band • Late 1990s -- 800 MHz public safety systems encounter increasing interference and “dead zones” • Problem traced to an incompatible mix of system architecture between commercial cellular carriers and traditional “High-Site, High-Power” systems operated by Public Safety.

7. Near/Far Problem “Near/far” problem – First responder is near the ESMR cell site and far from its own base station Public Safety BaseStation ESMRCellSite Strong signal from cell site 10 MILES Weak signal from public safety base station 2500 FEET Result: Signal from cell site overloads public safety handset

10. 800 MHz Report and Order (2004) • New band plan adopted to separate public safety from cellular systems • Nextel (now Sprint) must pay all rebanding costs incurred by public safety and other 800 MHz incumbents for “comparable facilities” • 36-month transition period

14. 800 MHz Transition Process • 36-month clock started on June 27, 2005 (except for border areas) • Planned June 26, 2008 end date now past • Transition is divided into four geographic waves • Each wave divided into two stages • Stage 1 – Relocation of Channels 1-120 • Stage 2 – Relocation of NPSPAC, Expansion Band • 800 MHz Transition Administrator (TA) administers the transition

15. Transition Waves 1-4

16. Rebanding – Stage 1 Start Channels 1-120 SMR/General Category NPSPAC (Public Safety) Interleaved SMR, B/ILT, Public Safety ESMR 1 2 (1) Channel 1-120 Non-ESMR licensees move to the Interleaved Band (Sprint vacates interleaved channels as needed to make room) (2) A few non-Nextel ESMR Systems move to the ESMR Band (Sprint vacates ESMR channels as needed to make room)

17. Rebanding – Stage 1 Finish Channels 1-120 (All Non-Sprint licensees vacated) NPSPAC (Public Safety) Interleaved SMR, B/ILT, Public Safety ESMR 1 3 2 3 • (1) Channel 1-120 cleared of all licensees except Sprint • 97% of non-border Channel 1-120 licensees have been cleared • (2) Channel 1-120 licensees relocated in Interleaved Band • (3) Sprint continues to operate on portions of Channel 1-120 block and on some interleaved channels

18. Rebanding – Stage 2 Start NPSPAC (Public Safety) Interleaved SMR, B/ILT, Public Safety ESMR Expansion Band Guard Band 2 1 3 (1) NPSPAC licensees move down 15 megahertz to new NPSPAC Band (2) Clearing of Expansion Band and Guard Band (3) Sprint vacates remaining channels in Interleaved Band

19. Rebanding – Stage 2 Finish NPSPAC (Public Safety) SMR, B/ILT, Public Safety Interleaved ESMR Expansion Band 1 Guard Band 2 3 (1) Sprint moves into new ESMR (old NPSPAC) band (2) Interleaved spectrum vacated by Sprint is available exclusively to public safety for 3 years (3) After 3 years, vacated spectrum is also opened to both public safety and Critical Infrastructure for an additional 2 years

20. Transition Steps – Negotiation/Mediation • Sprint and each licensee negotiate Planning Funding Agreement (PFA) • Licensee and vendor inventory equipment, develop rebanding plan and cost estimate for submission to Sprint • Sprint and each licensee negotiate Frequency Relocation Agreement (FRA) • Most negotiations mediated by a TA-designated mediator • If the parties cannot reach a mediated agreement, the TA refers the case to PSHSB, which has delegated authority under the 800 MHz R&O to rule on disputed issues de novo

21. Transition Steps – Implementation • First step – Retuning/replacement of licensee’s mobile/portable radios (“first touch”) • Retuning – new channels can be programmed into existing radio without removing old channels • Replacement – occurs when existing radio model can’t hold old and new channels simultaneously • System continues to operate on old channels until cutover • Second step – System “cutover” to new channels • Base station infrastructure retuning • System operates on new channels after cutover • Third step (not all systems) – Removal of old channels from mobile/portable radios (“second touch”)

23. Transition Progress (Non-Border Regions)As of February 2009 • Stage 1 – more than 97 percent of Channel 1-120 incumbents have relocated • Some licensees with both Channel 1-120 and NPSPAC systems will relocate in Stage 2 • Stage 2 – more than 32 percent of NPSPAC and Expansion Band incumbents have relocated • Stage 2 timeline longer due to number of large, complex public safety systems and more interoperability relationships among licensees • Many Stage 2 licensees received waivers of the June 26, 2008 deadline

24. Canada and Mexico Border Issues • Border regions are not subject to the 36-month timetable because of need to resolve cross-border spectrum allocation issues • Existing bilateral agreements with Canada and Mexico limit U.S. access to the 800 MHz band in border areas • Modifications are needed for border-area rebanding to be consistent with rest of U.S. • FCC working in coordination with State Department

25. Canada & Mexico Border Status • Canada Border: FCC has adopted new U.S.-Canada border rebanding plan • 30-month transition clock started October 14, 2008 • Ongoing coordination with Canada re impact of rebanding on Canada incumbents and 2010 Winter Olympics • Mexico Border: U.S.-Mexico negotiations continuing to develop border rebanding plan
