  1. FCC Actions To Support Development of WISPS Julius P. Knapp Deputy Chief Office of Engineering and Technology Federal Communications Commission

  2. Overview • Operation Under “Unlicensed” Rules • Operation under “Licensed” Rules • Commission Actions That Promote Development of WISPs: • More Spectrum for Unlicensed • Proposed Changes to Part 15 Rules

  3. Unlicensed Operation - Part 15 - Radio Frequency Devices • Provides For Operation of Low Power Transmitters Without a User License • Examples: Garage door openers; cordless telephones; keyless entry systems; radio controlled toys; anti-pilferage systems, wireless data networks (LANs, PANs, etc.)

  4. Part 15 Operating Conditions • Operator Must Eliminate Any Harmful Interference That May Occur or Cease Operation • Must Accept Any Interference That May Be Received • No Vested Right To Continue Using Any Frequency

  5. Controlling RF Interference • Unlicensed Devices Generally Share Spectrum with Other Radio Services • Interference To Other Services Minimized By Careful Selection of Frequencies and Technical Standards • Equipment Must Be Authorized (Certificated) to Show Compliance With FCC Standards

  6. “Spread Spectrum” Rules • Frequency Bands: • 902-928 MHZ • 2400-2483.8 MHz • 5725 - 5850 MHz • Technical Rules (Section 15.247): • Provides for frequency hopping systems and digital transmission systems • Power limit: Up to 1 Watt output power • Power reduction for high-gain antennas (omni vs. pt.-to-pt.) • Out-of-band & spurious emissions limits • Antenna must be permanently attached or unique connector • IEEE 802.11(b) & (g), Bluetooth operate under these rules in the 2.4 GHz band.

  7. U-NII - Rules • In 1996 the FCC Established Provisions for Unlicensed • National Information Infrastructure (U-NII) Devices • Led to the Development of IEEE 802.11(a) Link Indoor Devices Link Devices to Nodes Link Nodes (Campus) 50 mW Indoor Use Only 250 mW 1 W Provided A Total of 300 MHz of Spectrum! 5150 5250 5350 5725 5825 Frequency (MHz)

  8. Licensed Radio Services • “Licensed” Radio Services Have Interference Protection • Flexible Rules: Licensee May Choose Service/Technology • Examples: Cellular; PCS; MMDS; LMDS, etc. • Equipment Must Meet Basic Technical Standards • Equipment Authorization is Required

  9. Equipment Authorization Required • Most Radio Transmitters Require “Certification” to Show They Meet the FCC Technical Standards • Certification Can be Issued By The FCC Or A Telecommunications Certification Body • Compliance Label: • FCC Identifier • Compliance statement • Equipment Certification Records Are Publicly Available On The FCC Web Site

  10. More Spectrum for Unlicensed • Spectrum Policy Task Force Report Recommended FCC Provide More Spectrum For Unlicensed Operations • FCC Notice of Inquiry (ET Docket 02-380): • TV Broadcast Bands below 900 MHz • 3650 - 3700 MHz

  11. More Spectrum for Unlicensed • World Radio Conference Provided An Additional • 255 MHz of Spectrum for U-NII Devices • FCC Plans Adopt Rules Shortly (ET Docket 03-122) Link Indoor Devices Link Devices to Nodes Provides A Total of 555 MHz of Spectrum! Link Nodes (Campus) 50 mW Indoor Use Only 250 mW Proposed 250 mW 1 W 5150 5250 5350 5470 5725 5825 Frequency (MHz)

  12. Proposed Changes to Part 15Potentially Beneficial to WISPS • NPRM 9/10/03 (See ET Docket No. 03-201) • Provide for advanced antenna technologies and sectorized antennas in the 2.4 GHz band • Modify the antenna replacement restrictions • Modify equipment authorization procedures to allow configuration of custom systems without obtaining certification for each combination of transmitter/amplifier/antenna • Invite comment on ways to improve sharing

  13. Tips for Sharing the Spectrum • Unlicensed Devices Have Done Very Well In Sharing The Spectrum Without Causing Mutual Interference • Make Sure You Comply With The Rules • Be a Good Neighbor - - Many Interference Problems Can Be Resolved With Simple Technical Fixes

  14. Thank You Federal Communications Commission Office of Engineering and Technology
