By the Commission: Commissioner Barrett issuing a separate statement.

I.Introduction

1. On July 2, 1991, we released a Notice of Inquiry (Inquiry) to gather

information on how to promote more efficient use of the frequency bands below 512 MHz allocated

to the private land mobile radio (PLMR) services….

Is a mandate from the Federal Communications Commission

Applies to VHF High Band and UHF Systems VHF High Band refers to 150-174mHz UHF Refers to 421-512mHz

Page 6: The Future of Communications 1. 2 Police Cars Ambulances Fire Trucks Graders Dump Trucks Pool Cars Pickups SUVs 3

The amount of VHF and UHF spectrum available to Public Safety has essentially remained unchanged.

Page 7: The Future of Communications 1. 2 Police Cars Ambulances Fire Trucks Graders Dump Trucks Pool Cars Pickups SUVs 3

As agencies have grown, their radio needs have grown, too.

Infrastructure is Expensive

Mobiles and Portables are expensive

Excess Capacity

Page 10: The Future of Communications 1. 2 Police Cars Ambulances Fire Trucks Graders Dump Trucks Pool Cars Pickups SUVs 3

Accomplishes this by squishing signals in half.

Reduces channel spacing by half, effectively “doubling” the number of channels.

Older Volunteer Responder Pagers and Monitor Receivers are NOT Narrowband Capable.

Minitor I – IV Must Be Replaced Minitor V is Narrowband capable Older Plectron AND other Station

Alerting/Siren activation systems are not Narrowband capable.

Page 13: The Future of Communications 1. 2 Police Cars Ambulances Fire Trucks Graders Dump Trucks Pool Cars Pickups SUVs 3

VHF/UHF Subscriber Radios will have to be replaced if they are roughly 11 years old or older.

Newer subscriber radios will require reprogramming.

No New Systems will be licensed to use Wide Bandwidth.

No Existing Systems using Wide Bandwidth will be modified.

New Manufacturer equipment can only be narrowband.

“With the increasing efforts of NPSTC and our member

organizations to build awareness of the Jan. 1, 2011 interim deadlines and

Jan. 1, 2013 required use deadline in the VHF and UHF bands, public safety

users of land mobile radio systems are asking detailed implementation

questions and raising a growing list of concerns. Most of these issues are

directly related to the Jan. 1, 2011 deadline, and mainly express user

concerns about either interoperability during the two year interim period or

costs to purchase equipment with capabilities beyond what users must

deploy.”

Inventory your system

Plan your mobile and portable radio purchases

Plan your Infrastructure Purchases

Plan your system Upgrades

Plan for unintended consequences20

this….

Who will do the programming? Will the programming occur on site or at a shop?

Do the radios have enough channel capacity? Wide and Narrow versions of all the channels? Different Zone?

How many times will each radio have to be programmed?

24

Page 25: The Future of Communications 1. 2 Police Cars Ambulances Fire Trucks Graders Dump Trucks Pool Cars Pickups SUVs 3

Change over sites one by one Requires wide and narrow channels

of the same frequency Change over channels one by one

Requires reprogramming radios multiple times

Run the new narrowband system concurrently with the old system Requires additional antenna,

transmission line, duplexer, etc.

25

Page 26: The Future of Communications 1. 2 Police Cars Ambulances Fire Trucks Graders Dump Trucks Pool Cars Pickups SUVs 3

Narrow Band systems may not have the same coverage as a comparable Wide Band system. Most engineering documents indicate reduced

range, when the only change is narrowing the signal (Power, antenna, frequency stay the same)

Additional sites / equipment may be required

26

Page 27: The Future of Communications 1. 2 Police Cars Ambulances Fire Trucks Graders Dump Trucks Pool Cars Pickups SUVs 3

Digital Signals

Additional features Unit ID, Emergency button, Individual Call,

etc.

Improved efficiencies provide comparable coverage

Equipment is more expensive27

Page 28: The Future of Communications 1. 2 Police Cars Ambulances Fire Trucks Graders Dump Trucks Pool Cars Pickups SUVs 3

Replace Mobiles and Portables

and Use MIXED MODE for

in-agency communications

Install a new, P-25 repeater and operate it in MIXED MODE.

28

Use an additional channel in the radio that transmits AND receives in ANALOG, to maintain interoperability communications!

Vendors will attempt to steer you towards a proprietary system

This will lock you into sole-source vending

31

Page 32: The Future of Communications 1. 2 Police Cars Ambulances Fire Trucks Graders Dump Trucks Pool Cars Pickups SUVs 3

Outside agencies cannot communicate with you on your repeater

Use a gateway between your system and an analog channel

Buy enough radios for normal mutual aid partners (proprietary shared)

32

became “trendy” Used Statewide

LICENSED BY INDIVIDUAL AGENCIES!

Received audio may be very soft and quiet

Wideband radios must turn up volume to hear. Once a second wideband radio transmits, the

original wideband radio’s received audio will be very loud

Audio may not be picked up by wideband receiver

35

Page 36: The Future of Communications 1. 2 Police Cars Ambulances Fire Trucks Graders Dump Trucks Pool Cars Pickups SUVs 3

Received audio may be loud, distorted, or inaudible Turning down the volume may mean missed

calls from a NarrowBand radio Communications may work at a distance

but not close together

36

Page 37: The Future of Communications 1. 2 Police Cars Ambulances Fire Trucks Graders Dump Trucks Pool Cars Pickups SUVs 3

Program both a “wide” and “narrow” version of each MA Channel

Append the label of the NarrowBand Version with an “N”

Communicate with your mutual aid partners

Use this opportunity to do operator training

Complaints: about expense Why, oh, WHY, didn’t anyone TELL ME! Can’t we just leave things alone?

Worries that Gramma won’t get tornado warnings

Huge outcry that we’re not ready Tremendous pressure from constituents DATE WAS MOVED BACK LESS THAN

FOUR MONTHS.38

Page 39: The Future of Communications 1. 2 Police Cars Ambulances Fire Trucks Graders Dump Trucks Pool Cars Pickups SUVs 3

FCC Fines can be thousands per day, per violation.

Spectrum is too crowded to allow “courtesy release.”

Ensure your licensing is accurate

Latest recommendations are automatic cancellation of wide band licenses on

January 1, 201339
