800 MHz Reconfiguration

1. 800 MHz Reconfiguration Preparing Licensees to Retune April 7, 2005

2. Timeline for Reconfiguration • February 7 Nextel accepts FCC’s decision • March 11 FCC approves TA’s Regional Prioritization Plan • June 27 Reconfiguration commences / Wave 1 (channels 1- 120) • October 3 Wave 2 commences (channels 1- 120) • January 3, 2006 Wave 3 commences (channels 1- 120) • April 3, 2006 Wave 4 commences (channels 1- 120) • June 2008 Reconfiguration scheduled completion

3. Current 800MHz Band 821 809 824 806 816 General Category NPSPAC (Public Safety) ESMR (Upper 200) Interleaved Spectrum 700 MHz Public Safety Band Cellular A & B Bands Down-Link [MHz] 851 869 854 861 866

4. What happens during reconfiguration? NPSPAC Public Safety users would be relocated to 851-854 MHz from their current allocation of 866-869 MHz. 800 MHz Up-Link [MHz] 824 809 817 806 815 816 821 Analog Bus/ILT/ SMR Mixed-Use 4 MHz (2 + 2 MHz) [Public Safety Guard Band] 700 MHz Public Safety/ Aviation Air- Ground Analog Public Safety/ Bus/ILT/SMR Mixed-Use 10 MHz (5 + 5 MHz) AFTER Relocated NPSPAC Public Safety 6 MHz (3 + 3 MHz) Low Site, Low Power Digital SMR 16 MHz (8 + 8 MHz) [Optional Guard Band As Needed] [Former NPSPAC Channels Reallocated To Digital SMR] Cellular A & B Band Expansion Band* Guard Band** 869 860 861 851 854 862 866 [MHz] Down-Link Example: 867.5250 would retune to 852.5250 * No public safety system will be required to remain in or relocate to the Expansion Band; although they may do so if they choose. ** No licensee may be involuntarily relocated to occupy the Guard Band.

5. How we all can get it DONE! • Reconfiguration Sequence • Transition Administrator releases frequency plans • Nextel initiates negotiations with licensees • Nextel and licensee execute channel exchange agreement • Nextel pays all reasonable costs associated with reconfiguration • Reconfiguration Steps • Nextel discontinues use of “old” channels • Licensee uses “old” Nextel channels for reconfiguration • Licensee retunes mobiles to work on the channels given up by Nextel • Licensee discontinues use of its original channels

6. Negotiations with licensees • Affected licensees must enter into an agreement with Nextel before reconfiguration can begin • Nextel has already begun voluntary negotiations with licensees • Per FCC requirements, Nextel will proceed in this order for each wave: • Move non-Nextel, non-Southern LINC channels 1-120 • Relocate NPSPAC licensees currently in 821-824 MHz and 866-869 MHz band and public safety who elect to move out of the expansion band

7. Preparing for negotiations • Consult with the TA’s Regional Prioritization Plan to see when your area is due to be reconfigured • Assemble your reconfiguration team and identify/authorize a representative to consult with Nextel • Make certain your FCC licenses are in good order • Compare your records to those of the FCC • Take an inventory of all radio equipment, noting make and model (not serial number), and including: • Number of mobile units • Number of combiners • Number of repeaters • Determine which call signs and frequencies will be reconfigured • Develop a detailed list of what needs to be changed • Prepare a preferred work schedule, including times of day to minimize disruption

8. Nextel’s Commitment 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
