2. New Band Plan New Technical Rules Exclusive Service Areas Transition Process Other Elements Key Provisions of WCA/NIA/CTN Proposal

3. New Band Plan 3 principal band segments: – Middle Band Segment (MBS) –Lower Band Segment (LBS) –Upper Band Segment (UBS) 2 “Guardband” Segments: –Transitional Bands J and K Current I band with changes

4. The Old and New Bandplans A1 B1 A2 B2 A3 B3 A4 B4 C1 D1 C2 D2 C3 D3 C4 D4 E1 F1 E2 F2 E3 F3 E4 F4 G1 H1 G2 H2 G3 H3 G4 I A1A2 A3B1 B2B3 C1 C2C3D1 D2D3 J A4 B4C4D4E4 F4 G4 K E1 E2E3F1F2 F3 H1 H2H3 G1G2 I G3 WCS/PCS-like licensing TDD or FDD upstream Cellular-friendly technical rules WCS/PCS-like licensing TDD or FDD downstream Cellular-friendly technical rules MDS-like licensing and technical rules Primarily high power downstream 2500 MHz 25662572 261426202686 2690 New Band Plan

5. New Band Plan – Mid Band Segment “MBS” suitable for Video Services, but usable for data services Big-Stick, High-Power, One-Way 7 Channels @ 6 MHz (4 th channel in each group) Will reside at current Channels C3-E2 (C3, D3, C4, D4, E1, F1, E2)

6. New Band Plan – Lower/Upper Band Segments “LBS/UBS” Intended for two-way digital services Low-Power, Cellularized, Two-Way Contiguous channels in each Group LBS: 12 channels @ 5.5 MHz UBS: 12 channels @ 5.5 MHz

7. New Band Plan – Transitional Bands J Band – 6 MHz drawn from A, B, C and D licensees K Band – 6 MHz drawn from E, F, H and G licensees

8. New Band Plan – I Band Existing ITFS response channels at 2686-2690 MHz, As now, except de-interleaved

9. Technical Rules for MBS Stay tuned for Harry Perlow

10. Technical Rules for LBS/UBS Stay Tuned for Harry Perlow

11. Exclusive Service Areas Relies on Geographic Service Areas – GSAs Modifies licensees’ PSAs by splitting overlap areas Creates exclusive areas of service for each licensee

12. Transition Process – Timing No specific deadline for transition – timing is determined by “Proponent” seeking to transition market at its expense Daisy Chain Effect – Proponent in Market A may have to transition nearby Markets B, and C etc.

13. Transition Process – Obligation of Proponent Convert existing ITFS video program services to licensee’s MBS channel(s) Provide new downconverters to ITFS receive sites for interference protection Coordinate timing and process of transition

14. Other Proposal Elements (1) FCC to resolve old 1995 MX applications for new stations by auction (as required by Communications Act) after final settlement opportunity

15. Other Proposal Elements (2) All unlicensed ITFS spectrum (White Areas) licensed by FCC on basis of Basic Trading Areas (BTAs) on channel group basis. In event of MX applications, resolve by auction

16. Other Proposal Elements (3) FCC urged to suspend construction deadlines for individual ITFS facilities. FCC also urged to grant renewal to any ITFS station where the station provided “substantial service” during the preceding license term.
