OBRA-93 reallocated 235 MHz

WRC-95 reallocated 66 MHz

BBA-97 reallocates 20 MHz

2007 IMT-2000/3G reallocates 45 MHz for

commercial use (45 MHz federal Spectrum

(1710 – 1755 MHz)

2010 National Broadband Plan (NBP) is looking at 500 MHz

additional spectrum for Commercial Wireless Broadband

(at least 250 MHz of Federal Spectrum, 1755 – 1780 MHz to start)

Relative spectrum

available prior to 1992

WARC-92 reallocated 91.5 MHz

How NAVAIR Ranges Are Spending SRF

Actions needed to compress telemetry operations into 1780 – 1850 MHz

while simultaneously expanding telemetry operations to C-band

Replace ALL airborne TM transmitters with at least Tier 1 (SOQPSK) spectrum efficient

transmitters

Protect all ground antennas against overload from LTE signals in 1755-1780 MHz band

• Filters/high dynamic filters, if not already installed

• New antennas, if old ones not modifiable

Add Tier 1 (SOQPSK) and Tier 2 (CPM) capability to all TM receivers not currently modified

Purchase of new transportable TM trailers to augment fixed sites being modified (i.e. no

impacts to RDT&E range missions and OPTEMPO)

Purchase and deployment of new and/or improved spectrum monitoring and direction finding

equipment

Spectrum Management actions to improve frequency deconfliction tools and to protect all

ground TM antennas regardless of registration status in government master file (GMF) or area

master files (AMF)

• Project Scope

Upgrade NAVAIR Ranges Spectrum Monitoring and Geolocation capabilities

• Additional sites and Hybrid monitoring, direction finding and geolocation solutions include TDOA (Time Difference of Arrival), Angle of Arrival (AOA) and CI (Correlative Interferometry)

• Improve geographical diversity for spectrum monitoring and geolocation capabilities

• Upgrade DOD Middle Atlantic (MIDLANTAFC) and Western Area (WAFC) Frequency Coordinators frequency de-confliction and mitigation capabilities

Spectrum Access R&D (SARD) TM Projects

• C-Band/Multiband Telemetry Antenna Project consists of five subprojects identified as Technology Shortfalls in the CTEIP funded TSCRS (Tri-Service C-Band Roadmap Study) Report

– #1: Broadband Conformal C-Band Missile Wraparound Antennas (NAWCWD, follow on to S&T effort)

– #2: Beam Switching Array Antennas (Georgia Tech Research Institute; Atlanta, GA)

– #3: Multiband Conformal Antennas for Aircraft Applications (Toyon; Goleta, CA)

– #4: High Altitude Coronal Efforts on Antenna Performance (not awarded yet)

– #5: Small, Medium Gain Multiband Receive Antennas (Georgia Tech Research Institute; Atlanta, GA)

Rapidly Changing Operational Spectrum Environment

Protective Legislation via NDAA-99/00 (PL 106-65 & 108-494) guarantee the Navy and DOD

resources (i.e. money & time) to effect a peaceful transition (i.e. no impact to mission)

from spectrum where we are primary into comparable spectrum

Efficiency Comparison of Telemetry

Modulation Schemes

PCM/FM SOQPSK Multi-h CPM

1440.5 MHz 1450.5 MHz 1460.5 MHz

Example 5 Mbps Signal

SOQPSK (Tier 1) Reduces Necessary Bandwidth by 50% Over PCM/FM

Multi-h CPM (Tier 2) Reduces Necessary Bandwidth by 25% Over SOQPSK

Multi- dB Processing Gain

• Extends Effective

Coverage

• Reduces Target Dropout

• Reduces ID Track Swaps

• Confirmed by Mode 5 M&S

and Flight Demo

• Mode 5 designed to not interfere with civilian Air Traffic

Control

– Lower interrogation rate

– Message design does not induce civil transponder

“squitter”

• Close coordination with FAA has resulted in positive

response

• Supports goal of unrestricted use for training and

operational missions
