2 White Space 101 General Terminology White Space Devices (WSD) TV Band Devices (TVBD) White Space Database (WSDB) Low Power Auxiliary (LPA) FCC Licensed device that is protected from interference from White Space Devices 4/15/2014 Wireless Mics, White Spaces and You 2

3 White Space Types of WSD Fixed Personal/Portable Mode I Personal/Portable Mode II Unlicensed device and must not cause interference to licensed users Nationwide use approved 4/15/2014 3

4 Fixed White Space Devices Any TV channel except 3, 4 & 37 Limited to 4 Watts ERP Antenna max height: 30 meters AGL Must access WSDB at least every 24 hours Must be location aware Professionally installed or Geo-location capability 4/15/2014 4

5 Personal/Portable Mode II TV channels & mw max or 40 mw if on adjacent TV channel Geo-location is required; +/- 50 meter accuracy Must check in with WSDB If it moves 100 meters or more At power up & every 24 hours 4/15/2014 5

6 Personal/Portable Mode I TV channels & mw max or 40 mw if on adjacent TV channel Not location aware Must check with its controller for channel At power up and every 60 seconds and shut down if it cannot contact it 4/15/2014 6

7 Licensed LPA Protection Distances Licensed LPA sites have a 400 meter protection radius from Mode I & II Personal/Portable WSD 1 km protection radius from Fixed WSD Assuming the LPA device is in the WSDB, this effectively protects unlicensed WSD from interference by licensed LPA devices! 4/15/2014 7

21 Point vs. Polygon Registration Point/Circle 3 km max between adjacent points, 25 points max 4/15/

22 Point vs. Polygon Registration 400 m protection from center point 400 m protection from polygon edge = 1.9 km radius 4/15/

23 Point vs. Polygon Registration 1 km protection from fixed WSD 1 km protection from polygon edge = 2.5 km radius 4/15/

24 White Space Registration Available White Space channels are calculated from: 1. WSD location 2. WSD type 3. Protected Registration type 4/15/

25 Personal/Portable Protection Zone (Dark Orange in polygon & Grey in point) LPA Protected Area White Space Devices are NOT allowed and channels are not available for WSD in this area. But 4/15/

26 Personal/Portable Protection Zone (Dark Orange in polygon & Grey in point) LPA Protected Area Mode I devices are not location aware and could accidently move into the protected area; possibly causing interference to protected LPA devices. 4/15/

27 Personal/Portable Available Area Fixed Device Protection Zone: Lite Orange or Between Circles 100 mw Device Ch 30, 31, mw Device Ch 21, 23, 27, 29, 30, 31, 32, 44, 45, 47, 48 4/15/
