1. Welcome to: Analyzing the New TV White Space Rules VoIP Users: If you are using VoIP for the audio portion of the presentation, you should already be connected to audio using your computer’s microphone and speakers (VoIP). A headset is recommended. Telephone Users: If you are joining the audio portion of this presentation VIA TELEPHONE, and haven’t already dialed in, simply dial the number you see in the section of the control panel marked “AUDIO” and use the access and pin codes provided there. Questions: We will address questions at the conclusion of this webinar. You may send your questions to us ANYTIME throughout the presentation-- via the text chat tool in the control panel, titled “QUESTIONS”. Viewing Tip: At any time throughout the presentation you may MINIMIZE the CONTROL PANEL and view just the presentation screen by clicking on the small double black arrows at the TOP of the control panel . This session is being recorded. We will send all attendees a link where you can access it as soon as it is posted.

5. Quick Recap: What is TV White Space? We are talking about the set of 6MHz VHF and UHF channels traditionally reserved for broadcast Television. Since the Digital Transition was completed, this encompasses channels 2-51 with some limitations (channel 37 is reserved for special applications).

6. TV White Space is the Gaps This map shows the service areas for a single TV channel (Channel 9) in the northeast US. Everything else on the map is “White Space”, representing spectrum that is potentially available for use by new TV Band devices.

7. The Macro Level View Rolling up all the “White Space” creates a nationwide footprint... …but the FCC rules limit how much whitespace each device type can access.

8. An Example of the Limitations In any given location (e.g. Zip Code 32746 Lake Mary, Florida), the channel availability will vary by device type after applying the FCC rules.

9. Worldwide Activity This is a review of US rules but similar activities are ongoing worldwide.

10. FCC rules First set of rules came out in November 2008. After much debate and protest a revised set of rules was published in September 2010. In addition a separate public notice is due to be published on Database providers.

11. White Space is Unlicensed with a Twist In many ways TV White Space rules mirror those of the Second ISM band which many of us are familiar with as it is used by 802.11 (WiFi), Bluetooth, and cordless phones. The twist is that this band has not been cleared so, depending on where you are in the country and what type of device you are using the spectrum that you can use varies. The 2008 rules proposed this be dealt with by both sensing and a database. The 2010 rules permit database only options. Note that the new rules allow for someone to prove a sensing only solution is an acceptable option.

13. The rules define different classes of devices that can use the TV White Space (fixed, P/P Mode I, P/P Mode II)

14. The rules define steps that the devices must take before they can use available channels

15. The rules define TV White Space Database requirements

17. Other Protected Entities The FCC licenses transmitters and this information can be obtained from the FCC (either CDBS or ULS) however there are users of the band that are receivers only (e.g. Cable headends, TV translator receive sites). These are not tracked by the FCC. The rules provide for these entities to register with a Database to ensure that they are protected.

18. Wireless Microphones Two types of wireless microphones use TV White Space. The first, licensed, is typically used by the broadcast industry. The second, technically illegal, is used by a wide range of churches, schools, entertainers and events. The Licensed users have been provided with a mechanism to register their locations of use in a White Space database to get protection. The FCC has dealt with the unlicensed users by ensuring that a significant percentage of the TV White Spaces will be reserved for them; while not stopping them from using the other available TV White Space.

19. New TV White Space Devices As an unlicensed band, devices are power limited. Three thresholds, fixed 4W, portable 100mw and portable 40mw. These will be discussed in more detail by Neeraj and Steve. The rules do not specify anything about technology. Expect solutions based on existing standards (WiFi, WiMax, LTE) as well as new ones. The rules require location awareness but do not specify how this is to be achieved.

21. Provide mechanisms for protected entities to register for their protection (e.g. MVPD, LPTV, TV Translator Sites)

22. Validate FCC ID of Mode I Personal/Portable devices

23. Share registered protected entity data with other database providers

27. Maximum of 76 meters above average terrain for tower site

30. Geo-location Database Channel must be available as determined by database, and operations on channel must cease if database indicates channel no longer available. Fixed TVBDs must avoid co-channel and first-adjacent channels. Fixed TVBDs must access database at least once a day to verify continuing availability of channels. Location of fixed TVBD must be accurate to within 50 meters as determined by incorporated geo-location or professional installer.

32. TV translator and MVPD receive sites within 80 km of the relevant contour

33. Broadcast Auxiliary Service links within 80 km of TVBD

34. PLMRS/CMRS co-channel stations within 134 km of TVBD and adjacent-channel stations within 131 km of TVBD

36. To ensure that unauthorized users cannot modify the device or control features

37. To ensure that they are capable of obtaining lists of available channels only with authorized database administrators

41. Why TV White Space Improvements of 2X to 3X over existing options In indoor applications the improvement in propagation through walls with the additional spectrum that has been made available should produce a 2-3X range improvement over existing 2.4GHz WiFi solutions.

43. Ch. 37 is reserved for medical telemetry & ch. 36 & 38 are reserved for wireless microphones (if unoccupied by TV stations)

44. Power output is 100mW (EIRP) for any channel non-adjacent to a TV broadcast

45. Power output is 40mW (EIRP) for any channel adjacent to a TV broadcast

47. A portable device that has geo-location capability and can access the database to obtain a list of available channels

48. Geo-location accuracy is +/- 50m & must be re-checked at power-on and every 60s while in active operation (non-sleep mode)

49. Mode II device can select its channel of operation

50. Mode II device can initiate and operate a network of fixed and/or portable devices

51. Mode II device can provide a list of channels to a Mode I device

52. Mode I

53. A portable device that does not have geo-location capability

54. Mode I device must obtain a list of channels from a Mode II or fixed device

55. Mode I device may NOT initiate a network of fixed and/or portable devices

57. Mode II device selects channel(s) of operation

58. Mode II device initiates network (SSID) and allows client devices to connectTVWS Database Access Point – Mode II device Client devices – Mode I devices

60. Mode II device selects channel(s) of operation

61. Mode II device initiates network (SSID) and allows client devices to connectTVWS Database Master Device – Mode II device Client devices – Mode I devices

64. Vice-chair: Peter Ecclesine (Cisco Systems)

65. Objective: Define modifications to both the 802.11 physical layers (PHY) and the 802.11 Medium Access Control Layer (MAC), to meet the legal requirements for channel access and coexistence in the TV White Space.

66. Uses 5, 10, & 20MHz channels that can operate in TV White Spaces.
