4 47 CFR Part 90 Subpart R (90.521) Frequency is / MHz 5 Blocks (A, B, C, D, E) D Block License on a nationwide basis Become part of the public safety/private partnership Wideband spectrum redesignated for broadband use PS Broadband Spectrum and the Narrowband spectrum is consolidated in a 12 MHz block at the top of the Band Internal guard bands Single nationwide licensee for PS BB spectrum (adjacent to the D block) 1 MHz downward shift Guard band A Block is relocated (Upper C and D Blocks) and Guard Band B is placed above NB Block 4

5 The FCC Order: Changes in the Band Plan MHz Original Narrowband Allocations Current Narrowband Allocations TV: 63/68 TV: 64/ MHz 5

6 Eligibility(90.523) State and local government entities Nongovernmental Organizations Conditions Support from governmental entity Operate according to the rules and terms of the license Certification/letter of support from governmental entity Authorizations are conditional 6

7 Eligibility Changes (90.523) Establishment of minimum requirements for the PSBL No commercial Interest Non-profit organization Broadly representative of PS user community 10 Certifications (10 geographically diverse state and local government entities) Authorize the PSBL to use the spectrum Authorizing entity s primary mission is provision of PS services 7

8 Administration of Interoperability Channels (90.525) State are responsible for administrating the interoperability channels Base and control station must be licensed individually Mobile and portable operations in interoperability channels si permitted provided entity meets May hold the license or approve other qualified entity to hold the license May delegate the approval process for interoperability channels to other entity (RPC) 8

9 Administration of Interoperability Channels Changes (90.525) References interoperability channels is in the / MHz (PS NB Portion of the Band) 9

10 Regional Planning Requirements (90.527) Regional Plan requirement Responsibility of RPC No change under new Rules 10

11 Public Safety Broadband Licensee (90.528) Pertains to / MHz Allocated on a nationwide basis for PSBB operations License to a single PSBL / MHz (Guard Band) License Area 48 States, Alaska, Hawaii, Gulf of Mexico and the US Territories 11

12 Public Safety Broadband Licensee (90.528) Continuation PSBL can authorize construction of operations of base stations except if individual license International agreements require coordination Submission of en environmental assessment Station would affect areas identified n FAA registration requirement Mobile/Portables do not need individual licenses (operate under the authority of PSBL) Term of license -10 years Entitle to renewal 12

13 Public Safety Broadband Licensee (90.528) Continuation PSBL may not be partitioned or disaggregated License transfer is not permitted Quarterly reporting of financial and operational information 13

14 Band Plan (90.531) Revises frequency of Base and mobiles use MHz use of base, mobile or fixed MHz-may be used only of mobile or fixed Narrowband segment 960 Channels (6.25 khz) MHz (Channels 1-960) MHz (Channels ) Internal Guard Band reserved MHz and MHz Broadband (Pursuant to the PSBL) MHz and MHz 14

15 Transmitting sites near the US/Canada or US/Mexico Border (90.533) Applies to license to operate one or more transmitters in MHz and MHz at location or locations North of Line A or within 120 km of US-Mexico Border License Conditions Operations must conform to the limitation on interference to Canadian television stations contained in agreements between US/Canada Accept any interference from UHF TV stations in Canada/ Mexico 15

16 Modulation and Spectrum Usage Efficiency Requirements (90.535) Modulation standard for stations operating in MHz and MHz Digital Modulation Mobiles and portables can use analog modulation only as secondary mode Exemption Mobiles and portables that operate in Low Power channels designated by (b)(3) and (b) (4) 16
