2. Topics • Wave Four rebanding options • Wave Four collaboration and process RABC M&PC Meeting March 2007

3. 800 MHz Wave 4 Rebanding (Cont.) • There are the three options that NYS sees • OPTION I: • (1) Move B/I-LT up to current Nextel bands, (2) Compress current PS 806 to lower end of the “band” (the below 816/861 MHz US allocation) and move the mutual aid channels down 15 MHz, (3) move NPSPAC into upper end of “band”, and, (4) move B/I-LT to the old NPSPAC band. • OPTION II: • (1) Move B/I-LT up to current Nextel bands, (2) Compress current PS 806 to upper end of the “band” (the below 816/861 MHz US allocation) and move the mutual aid channels down 15 MHz, (3) move NPSPAC into lower end of “band”, and, (4) move B/I-LT to the old NPSPAC band. • OPTION III: • (1) Move B/I-LT up to current Nextel bands, (2) move the mutual aid channels down 15 MHz and displace SMR as necessary, (3), move NPSPAC into current B/IL-T channels, and, (4) move B/I-LT to the old NPSPAC band.

4. 800 MHz Wave 4 Rebanding (Cont.) • PROs and CONs • OPTION I and OPTION II: • PRO: Keeps NPSPAC Together as much as possible. Eliminates junctions between 25-kHz and 12.5 kHz channels. • CON: Will require everyone in Region 2 to move. • CON: Will require reduced combiner separation on existing 806 systems, introducing loss, cost, and possibly reduced coverage. In addition to this, there may not be enough site real estate to add antenna systems if necessary • OPTION III: • PRO: Existing PS 806 will not need to move in Region 2. • PRO: Will utilize current channel separations on 806 antenna systems in Region 2. • PRO: Will offer better channel separations on NPSPAC Region 2 antenna systems. • CON: Will add 5 junction between PS 25-kHz and 12.5 kHz channels. These will need to be coordinated properly during the rebanding process RABC M&PC Meeting March 2007

9. NPSPAC Licenses (from Oct 2006) o: NY, PA, or OH x: Other RABC M&PC Meeting March 2007

10. PS 806 Licenses (from Oct 2006) o: NY, PA, or OH x: Other RABC M&PC Meeting March 2007

11. Rebanding on Option 3: Step (1) Pull Out R2 I/LT (Blue) and swap with newly structured NPSPAC (Red) In NYS, (as long as we keep flexibility during the freeze) we can make this move without taking any Nextel off of the air. Otherwise there is no intermediate resting place for Nextel Pull Out R7 I/LT (Blue) and do three way swap I/LT -> newly structured NPSPAC (Red) old block PS (Red) and old I/LT RABC M&PC Meeting March 2007

12. Rebanding on Option 3: Step (2) Pull Out R2 SMR (Green) and Move to Nextel Block (Green Yellow) Here, the R2 SMR lower than 809 corresponds to the New Mutual Aid and Guard channel locations These 10 channels are probably Nextel nearly everywhere anyway. Region 7 has few non PS channels below 809 MHz Pull Out R7 SMR (Green) and Move to Nextel Block (Green Yellow) RABC M&PC Meeting March 2007

13. Rebanding on Option 3: Step (3) NPSPAC and Old Block Need to recoup loss of about 100 PS 821 channels in Region 7 and ‘Outside that are lost due to being co-channel to Region 2 806 channels after rebanding. These would need to be about 50 25-kHz channels from the “freed” channels vacated by Nextel from 806-816 MHz in R7 and “Outside” NPSPAC Match R7 and “Outside” 806 channels for one-to-one swap for dual allocation channels lost by R2 806/NPSPAC mess.

14. NPSPAC and Old Block NPSPAC Only Mixed Use Non-ESMR ESMR Post Rebanding Structure Using Option 3 RABC M&PC Meeting March 2007

15. Wave Four Collaboration and Process • Will need to come up with integrated R2/R7 plan, that seamlessly matches to “outside” • Reassign most US NPSPAC and 806 in the Canadian border area • Impacts into Wave 1 spectrum as well • Will need to male sure we get R7 and “outside” spectrum to make us whole • Due to dual allocation 806 NPSPAC spectrum in R7 and “outside” • Channel by channel assignments will accomplish this RABC M&PC Meeting March 2007

16. Wave Four Collaboration and Process • Still working on what Region 3 wants to do in order to tie things together • Region 3 does not need to utilize same Option (Option 3) as NYS • Need to understand what Region 36 wants to do in order to tie things together • Region 36 probably should utilize the same Option as NYS • Once this is done, can plan to tie everything together • A great deal of reshuffling will occur within the new sub-bands in order to line everything up. • Currently working with OH, PA, MI, as well as the TA and FCC to try to pull this all together RABC M&PC Meeting March 2007
