Satellites are critical to economy, defense

Backbone of national TV, radio, and print media distribution

Billions of data, credit, banking transactions daily

Primary information source to millions of Americans

Essential to flexible global defense infrastructure

Satellites are a reliable infrastructure component

Largely independent of terrestrial network

Space assets out of reach, satellites and gateways redundant

Essential for disaster relief and recovery

Digital Audio Radio Services (DARS)Digital Audio Radio Services (DARS)

Applications in the early 1990’s proposed terrestrial repeaters to compensate for signal loss in urban canyons and rough terrain

FCC allocated DARS spectrum in competitive auction in 1997

Adjacent Wireless Cable Service (WCS) interference concerns and local radio content issues still being considered

Part 15 issues – WiFi and Bluetooth

FCC temporarily approved terrestrial repeater service in 2001 but has yet to issue final license rules

7

Mobile Satellite ServicesMobile Satellite Services

Satellite hybrid network proponents seek to combine the advantages of cellular and satellite systems

Terrestrial opponents charge that hybrid systems are an end-run around standard auction process

Satellite operators maintain that international satellite spectrum is unique

Arguments as to whether a single entity is needed to operate both the terrestrial and satellite component of spectrum

8

Digital Broadcast Satellites (DBS)Digital Broadcast Satellites (DBS)

FCC recently announced that it will authorize MVDDS under the FSS allocation in the 12 GHz band

MVDDS will share band with DBS and NGSO-FSS on co-primary (but non-interference) basis subject to service and technical rules

FCC adopted a geographic licensing scheme and will assign terrestrial licenses via auction

DBS, post-1993 spectrum purchased at auction

Satellite television operators are concerned that significant interference will occur if terrestrial re-use is allowed

Radar Detector InterferenceRadar Detector Interference

Satellite operators and their customers have suffered, and continue to suffer significant harm from radar detector interference

Radar interference often in excess of 100 X Part 15 interference criteria

Problems occurring across 10.7 - 12.7 GHz band

Satellite industry requesting current radar detectors off the market ASAP

11

Nextel Proposal (800 MHz)

Nextel seeks 10MHz of MSS spectrum for its 800 MHz band realignment plan

Proposed reallocation would hinder critical MSS services and other 800 MHz interference fix exists

• 3G

Optimistic estimates suggested that demand for 3G services might create urgent spectrum needs

Licensees need entire band to ensure growth and success of 2GHz MSS systems

Reducing processing time

Addressing mutual exclusivity

Discouraging speculative filings and ‘green mail’

Preserving replacement expectations

Developing meaningful milestones

Reduce need for interpretation and enforcement

Orbital Debris NPRMOrbital Debris NPRM

FCC recently released all-encompassing NPRM regarding Orbital Debris policies and practices

The current policy of a “self-policed” industry works well for US based GEO satellite operators:

Industry is highly motivated for economic reasonsNo collisions to date

U.S. has maintained excellent de-orbit record
