2. 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

3. 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

4. Discussion topics
Does the current IEEE (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 af provide the means to support TVWS DB access?
Ha-Nguyen Tran et al., NICT

5. 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

6. 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 sec (1 day)
Amendment: add the following charts
TVWS DB
Access

7. 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 k
Location request/report pairs are component of architecture
In u 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

8. 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

9. 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

10. 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
