5. 5 © 2011 CommScope, Inc Fixed Service Usage of 7 and 13 GHz The Good 7 & 13 GHz - 650 MHz of backhaul spectrum opened to Fixed Services usage – shared with existing Broadcast Users The Bad Only available for a Fixed Service link when a TV pickup market is not intersected The Ugly About 50% of the land mass and approximately 90% of the population cannot be served by this ruling

8. 8 © 2011 CommScope, Inc Fixed Service Usage of 7 and 13 GHz Details: 6875–7125 MHz (7 GHz) 25 MHz maximum channel bandwidth 6975–7025 MHz not available for Fixed Services –This exclusion in the middle of the band allows for a clean high/low separation for the Fixed Service channel plans and preserves dedicated spectrum for Part 74/78 operators 12700–13200 MHz (13 GHz) 50 MHz maximum channel bandwidth 13150–13200 MHz not available for Fixed Services –This exclusion at the top of the band preserves dedicated spectrum for Part 74/78 operators

10. 10 © 2011 CommScope, Inc Fixed Service Usage of 7 and 13 GHz Additional Challenges: Unconventional channel bandwidths for Fixed Service manufacturers Long term manufacturer support of these bands likely to be business model driven Lack of existing high/low infrastructure can present coordination challenges Some Part 74 and 78 incumbents requested more stringent requirements in the NPRM so Fixed Service operators may encounter coordination difficulties

11. 11 © 2011 CommScope, Inc Elimination of Final Link Rule Prior to this ruling Part 101 prohibited the final radiofrequency (RF) link in the chain of distribution of program material to broadcast stations (studio to transmitter link) Broadcasters were forced to use alternate spectrum for these links (950 MHz for radio & 2, 7, 13 or 23 GHz for TV BAS) The 950 MHz and 7 GHz bands became very congested and often links were too long to use 23 GHz as an alternative All “Final Links” can now use any of the Part 101 frequency bands without restriction

12. 12 © 2011 CommScope, Inc Adaptive Modulation (ACM) changes the penalty to the user for deep fading situations Without ACM  link disconnection  outage/unavailability With ACM  reduced capacity Reduced capacity likely to be more acceptable than outage Details: Meet 99.95% reliability in accordance with the minimum requirement defined in 101.141 This means that 4.38 hours (0.05%) of the year you can drop down one mode below the required minimum as defined in 101.143(a)(3) Radio manufacturers are not required to provide fail-safes to ensure that the radio does not exceed the allowable yearly time restriction There is some concern that some operators could take advantage of the requirement and under-design systems Formal Procedures for Adaptive Modulation

13. 13 © 2011 CommScope, Inc FCC Declined “Auxiliary” Fixed Stations Auxiliary Stations Proposal would have allowed and encouraged: –Use of minimally compliant antennas –Unreasonably high Effective Isotropic Radiated Power (“EIRP”) –Time Division Duplex (“TDD”) systems in bands with exclusively Frequency Division Duplex (“FDD”) characteristics –The Part 101 bands would have effectively become point to multipoint
