Presentation Transcript

  1. Spectrum sharing and information architecture Martin BH Weiss mbw@pitt.edu

  2. Outline • Context • White Spaces • Federal Commercial sharing • Discussion and conclusions

  3. Motivation for spectrum sharing 2013 2005

  4. Motivation for spectrum sharing

  5. Factors affecting sharing • Interference is inevitable when spectrum is shared, so how is risk managed? • Sensing • Enforcement • How are various spectrum related rights defined (and managed)?

  6. Some current US spectrum sharing initiatives • Commercial • TV White Spaces • Federal-commercial • 1695-1710 MHz • 1755-1850 MHz • 3550-3600 MHz

  7. Case 1: TV White Spaces • What are spectrum “white spaces”? • What does this have to do with television?

  8. Sharing TV White Spaces • What do you need to know? • What are approaches to finding the information you need? • Sensing • Databases

  9. What does the TVWS database look like? • Let’s look at examples • http://whitespaces.spectrumbridge.com/whitespaces/home.aspx • http://www.google.org/spectrum/whitespace/

  10. Content • What information is provided? • How would you use it?

  11. Case 2: Federal and Commercial sharing • 1695-1710MHz • Currently assigned to weather satellite downlinks • Satellites are in polar orbit • Proposed for LTE uplinks, probably paired with the 2180-2200 MHz band for the downlink

  12. Challenge • How do you protect the “incumbents”?

  13. Exclusion zones • Static • Dynamic

  14. Operations of database-driven spectrum sharing • Assuming you have a need to establish a communication network, you must … • Find out where you are • Find out what channels you can use • Determine when you can use them at that location • Determine if those channel characteristics are suitable for your application • Transmit and follow the requirements of channel use

  15. Web interfaces for spectrum sharing in general • What needs to be in the database? • How context-specific is the information? • Who needs to see it? • How do you design it for human and machine users?
