What is a Wiki? A website that allows the creation and editing of online encyclopedia-like content in an open and collaborative environment A wiki invites all users to edit any page or to create new pages within the wiki Web site, using only a plain-vanilla Web browser without any extra add-ons [Ward Cunningham, inventor of the wiki] 11/17/2018

Advantages of a Wiki Leverages a much broader range of knowledge and expertise than can be achieved by one person Effort is distributed among many, with each person contributing knowledge in their particular realm of experience and interest Self-correcting Self-updating The wiki goal: Authoritative, searchable, publicly available knowledge base, including text, images, documents, references, and links to relevant external material 11/17/2018

What is SpectrumWiki? A wiki enhancement to an existing spectrum-focused Web site that is optimized for information about the use of the radio spectrum SpectrumWiki build up band-by-band information on: Specific uses for each band, including current, historical, and future applications/systems/technologies Pending proceedings, rule changes, legislation, auctions, and current events that impact each band and each service Technical information (propagation characteristics, hardware & antennas, etc.) Other useful information as supplied by the contributors 11/17/2018

Why Create a Spectrum Wiki? Ideal (and possibly only) method to collect and organize detailed and authoritative band-by-band information about how the radio spectrum is used No single person possesses detailed knowledge and expertise of more than a small fraction of radio spectrum uses and applications The totality of information to be collected and presented by SpectrumWiki will be invaluable to the wireless community for regulatory, technical, coordination, and informational purposes 11/17/2018

Why not use Wikipedia? Wikipedia is a great resource, but is not suitable for researching information pertaining to radio frequencies or services Wikipedia is driven by keywords, not by alternative data such as frequencies or services Wikipedia cannot be queried to display, for example, all the uses of the band 1850 – 1990 MHz, or all of the applications of the Broadcasting-satellite (space- to-Earth) service. Wikipedia requires some knowledge of HTML and of the Wikipedia editing language SpectrumWiki will, to the greatest extent practicable, be optimized for radio spectrum information, reducing the need for specialized syntax Wikipedia will be a valuable external reference, but it does not provide the intrinsic specialized capabilities envisioned for SpectrumWiki. 11/17/2018

What About Spectrum Dashboard? The FCC has rolled out a nice graphical interface called Spectrum Dashboard, “for citizens to search spectrum in the United States” SD is a good entry point for basic information on allocations, licensees & licensing statistics, and high-level descriptions of spectrum use SD contains only official information approved for public release by the FCC No extensive background information, or information that is contrary to, or critical of, government spectrum policy Example entries 1525 – 1559 MHz: “This band is used in the Mobile Satellite Service” 1559 – 1610 MHz: “This band is used in the Radionavigation Satellite Service” 18 words total, and no mention of one of the hottest current spectrum issues: Potential interference from LightSquared MSS ancillary terrestrial service (1525 – 1559 MHz) into the GPS L1 downlink (1559 – 1610 MHz) (No mention of ATC or GPS, for that matter!) SD will never be a portal for gleaning “the rest of the story” SD is a good complement to SpectrumWiki, especially for information on current licensing data by band and by geographic area http://reboot.fcc.gov 11/17/2018

The Starting Point As a starting point, SpectrumWiki will be pre-populated with the following information: Wireless Spectrum Finder (aka Spectrum Guide), by Benn Kobb 2002 book on telecommunications, government, and scientific radio frequency allocations in the U.S., 30 MHz – 300 GHz Most of the information is in need of updating Needs to be expanded below 30 MHz Rights to WSF/SG are now owned by SpectrumWiki NTIA Federal Spectrum Use Summary (2010) Very general information on Federal spectrum use from 30 MHz to 3 THz Needs expansion below 30 MHz Information is very general; more specifics are needed 11/17/2018

Current Status and Schedule The wiki functionality is presently under development Initial concepts, mock-ups, and beta code have been created The initial SpectrumWiki database is being developed A basic functioning beta site (wiki only) is expected to be available for testing in summer 2011 The wiki functionality will be incorporated into the existing site ~fall 2011 11/17/2018

SpectrumWiki Beta (Example Entry) Example: Create a new Wiki entry Explanation of how the latest generation of consumer “atomic clocks” operate WWVB time signals @ 60 kHz Text entry with two accompanying photographs 11/17/2018

SpectrumWiki Beta (Start New Entry) 11/17/2018

SpectrumWiki Beta (Edit New Entry) 11/17/2018

SpectrumWiki Beta (Add a Picture) 11/17/2018

SpectrumWiki Beta (Preview) After submitting the new wiki entry, it will appear whenever any user submits a query that includes the frequency 60 kHz Anyone reading the entry can further edit the material to correct, expand, update, or improve the information 11/17/2018

SpectrumWiki Next steps: Summary Contributors First version of SpectrumWiki will require validation for all contributors to help assure quality of contributions Username/password will be required to enable editing No authentication will be required to view the site Interested beta contributors and beta testers are welcome Summary SpectrumWiki will combine experts across a wide spectrum of spectrum, with web-enabled collaborative techniques, to create an encyclopedic inventory of U.S. radio spectrum utilization and applications 11/17/2018
