Abstract This document introduces requirements about TVWS DB access The intent is for the discussion of possible amendments to support TVWS DB access Ha-Nguyen Tran et al., NICT

Summary of FCC rules regarding TVWS database access Fixed and Mode II TVBD must access the TVWS database, where the TVWS DB is implemented in the Internet DB access frequency Fixed TVBD: at least once a day Mode II TVBD: Each time it is activated from a power-off condition After location change during operation Information exchange From TVBD to database FCC Identifier Serial number assigned by the manufacturer geo-location information (latitude and longitude, NAD 83) From database to TVBD: available channels for secondary use Ha-Nguyen Tran et al., NICT

Discussion topics Does the current IEEE 802.11 (2007) and subsequent amendments specs provide means to Access the TVWS DB in the Internet? Access the TVWS DB regularly according to FCC rules? Obtain the device’s FCC ID, serial number, and its current geo-location information? Send the above information to TVWS DB? Obtain available channels information from TVWS DB? If NOT Shall 802.11af provide the means to support TVWS DB access? Ha-Nguyen Tran et al., NICT

Requirement and Amendment (1) Requirement 1: Access the TVWS DB in the Internet Means to obtain IP address(es) of the TVWS DB Security mechanisms, etc. Amendment: Interface to obtain IP address Information element for IP addresses of TVWS DB Ha-Nguyen Tran et al., NICT

Requirement and Amendment (2) Requirement 2: Access the TVWS DB regularly according to FCC rules Means to get accurate time A counter which supports the counting of 86400 sec (1 day) Amendment: add the following charts TVWS DB Access TVWS DB Access Checking Power and Location Counter < 86400 No Counter = 0 Yes OFF  ON Location change Counter +1 Yes No Fixed TVBD Mode II Ha-Nguyen Tran et al., NICT

Requirement and Amendment (3) Requirement 3: Obtain device’s ID and geo-location Interface to obtain FCC ID, serial number, geo-location from TVWS device Geo-location information is available In 802.11k Location request/report pairs are component of 802.11 architecture In 802.11u D8.0 AP STA: Generic Advertisement Services (GAS) A STA having dot11InterworkingServiceEnabled set to true, may retrieve an AP's Geospatial location using Native-GAS procedures. dot11APGeoLocation element of AP MIB Non-AP STA Location information Non-AP location is approximated using AP’s location information Amendment Interface to obtain FCC ID and serial No. Ha-Nguyen Tran et al., NICT

Requirement and Amendment (4) Requirement 4: Send ID and geo-location to TVWS DB Amendment New information elements for FCC ID, Serial number Ha-Nguyen Tran et al., NICT

Requirement and Amendment (5) Requirement 5: Obtain list of available channels from TVWS DB Amendment Information element for list of available channels Ha-Nguyen Tran et al., NICT

Conclusions This document showed technical requirements to support TVWS DB access This document proposed the following amendments new interfaces to obtain FCC ID, serial number, IP address of the TVWS DB modification of existing timer to accommodate long-time counting (e.g. 1 day) additional information elements to carry the following information FCC ID Serial number List of available channels Ha-Nguyen Tran et al., NICT
