2. Overview Operation Under “Unlicensed” Rules Operation Under “Unlicensed” Rules Operation under “Licensed” Rules Operation under “Licensed” Rules Commission Actions That Promote Development of WISPs: Commission Actions That Promote Development of WISPs: More Spectrum for Unlicensed More Spectrum for Unlicensed Proposed Changes to Part 15 Rules 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 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.) 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 Operator Must Eliminate Any Harmful Interference That May Occur or Cease Operation Must Accept Any Interference That May Be Received Must Accept Any Interference That May Be Received No Vested Right To Continue Using Any Frequency No Vested Right To Continue Using Any Frequency

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

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

7. U-NII - Rules 50 mW Indoor Use Only 250 mW 1 W 51505250535057255825 Frequency (MHz) Link Indoor Devices Link Devices to Nodes Link Nodes (Campus) In 1996 the FCC Established Provisions for Unlicensed National Information Infrastructure (U-NII) Devices Led to the Development of IEEE 802.11(a) Provided A Total of 300 MHz of Spectrum!

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

9. Equipment Authorization Required Most Radio Transmitters Require “Certification” to Show They Meet the FCC Technical Standards 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 Certification Can be Issued By The FCC Or A Telecommunications Certification Body Compliance Label: Compliance Label: FCC Identifier FCC Identifier Compliance statement Compliance statement Equipment Certification Records Are Publicly Available On The FCC Web Site 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 Spectrum Policy Task Force Report Recommended FCC Provide More Spectrum For Unlicensed Operations FCC Notice of Inquiry (ET Docket 02-380): FCC Notice of Inquiry (ET Docket 02-380): TV Broadcast Bands below 900 MHz TV Broadcast Bands below 900 MHz 3650 - 3700 MHz 3650 - 3700 MHz

11. More Spectrum for Unlicensed 50 mW Indoor Use Only 250 mW 1 W 51505250535057255825 Frequency (MHz) Link Indoor Devices Link Devices to Nodes Link Nodes (Campus) World Radio Conference Provided An Additional 255 MHz of Spectrum for U-NII Devices FCC Plans Adopt Rules Shortly (ET Docket 03-122) Provides A Total of 555 MHz of Spectrum! Proposed 250 mW 5470

12. Proposed Changes to Part 15 Potentially Beneficial to WISPS NPRM 9/10/03 (See ET Docket No. 03-201) NPRM 9/10/03 (See ET Docket No. 03-201) Provide for advanced antenna technologies and sectorized antennas in the 2.4 GHz band Provide for advanced antenna technologies and sectorized antennas in the 2.4 GHz band Modify the antenna replacement restrictions 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 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 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 Unlicensed Devices Have Done Very Well In Sharing The Spectrum Without Causing Mutual Interference Make Sure You Comply With The Rules Make Sure You Comply With The Rules Be a Good Neighbor - - Many Interference Problems Can Be Resolved With Simple Technical Fixes Be a Good Neighbor - - Many Interference Problems Can Be Resolved With Simple Technical Fixes
