4.1 Introduction
This clause describes the general WSD GLDBs architecture as well as the reference model of the logical entity, the
GLDB, involved in the scope. The architecture shows the relationship of logical entities and the logical interface as
detailed in the following clauses. The reference model shows the abstract architecture of components of logical entities
and the logical interface.

4.2 Architecture
Figure 4.1 shows the instance of the G-G logical interface. The interface is used for the information exchange between
GLDBs for enabling the operation of White Space Devices (WSDs) for the protection of the incumbent service.
Figure 4.1: Architecture
4.3 Reference model of GLDB
Figure 4.2 shows an architectural view of a GLDB emphasizing the separation of GLDB into Database function, Geo-
location function and G-G Interface function. A function can access the services provided by another function via a
corresponding Service Access Point (SAP). A GLDB exchanges information with another GLDB by accessing
communication services via the Com-SAP.
The DB-SAP is used by the G-G Interface function to access the services provided by the Database function such as
registration of CRS and provision of incumbent information.
The GL-SAP is used by the G-G Interface function to access the services provided by the Geo-location function such as
the calculation of location specific EIRP that a WSD in a CRS can use in a frequency band.
The Com-SAP is used by the G-G Interface function to access communication services provided by communication
function for the information exchange with another G-G interface function.
Note that the G-G interface function inside the GLDB uses the services provided at the above three SAPs to realize the
logical interface between different GLDBs.

• The reference point shall support information exchange between GLDB A and GLDB B to allow GLDB A to
obtain information about the CRSs that are managed by GLDB B that affect the interference to incumbents
registered in GLDB A. Those CRSs may create interference below the interference reference field strength at a
given location probability of the incumbents that are registered in GLDB A. However, they may still
contribute adversely when considering aggregate/cumulative interference (see also section A11.1.1.4 of
ECC report 186 [i.2]).

service. The architecture stems from the system requirements described in clause 7.1 of ETSI TS 102 946 [i.1].
System Architecture and High Level Procedures for Coordinated and Uncoordinated Use of TV White Spaces are
described in ETSI TS 103 145 [i.4].

4 Overview of WSD GLDBs architecture reference
model
4.1 Introduction
This clause describes the general WSD GLDBs architecture as well as the reference model of the logical entity, the
GLDB, involved in the scope. The architecture shows the relationship of logical entities and the logical interface as
detailed in the following clauses. The reference model shows the abstract architecture of components of logical entities
and the logical interface.

4.2 Architecture
Figure 4.1 shows the instance of the G-G logical interface. The interface is used for the information exchange between
GLDBs for enabling the operation of White Space Devices (WSDs) for the protection of the incumbent service.
Figure 4.1: Architecture
4.3 Reference model of GLDB
Figure 4.2 shows an architectural view of a GLDB emphasizing the separation of GLDB into Database function, Geo-
location function and G-G Interface function. A function can access the services provided by another function via a
corresponding Service Access Point (SAP). A GLDB exchanges information with another GLDB by accessing
communication services via the Com-SAP.
The DB-SAP is used by the G-G Interface function to access the services provided by the Database function such as
registration of CRS and provision of incumbent information.
The GL-SAP is used by the G-G Interface function to access the services provided by the Geo-location function such as
the calculation of location specific EIRP that a WSD in a CRS can use in a frequency band.
The Com-SAP is used by the G-G Interface function to access communication services provided by communication
function for the information exchange with another G-G interface function.
Note that the G-G interface function inside the GLDB uses the services provided at the above three SAPs to realize the
logical interface between different GLDBs.

Figure 4.3 shows an alternative view of the reference model for the information exchange between two GLDBs. A
communication function is a hardware/software module that provides the communication services required by the

5 Reference Points
5.1 Reference point: Logical interface between GLDBs
Figure 5.1: Reference point for information exchange between GLDBs
Figure 5.1 shows the reference point between GLDBs which is the G-G logical interface between the GLDBs for
enabling the operation of White Space Devices (WSDs) for the protection of the incumbent service. Specifically, the
reference point enables one GLDB to interface with other GLDBs in order to guaranty that the operations of CRS
managed by one GLDB satisfy the protection requirements of incumbents such as the Terrestrial Broadcasting Service
registered in different GLDBs as specified by respective regulations.
5.2 Reference point requirements
The following requirements do not mandate that GLDB implements any specific calculation methods.
• The reference point shall support information exchange between GLDB A and GLDB B to allow GLDB A to
discover its affecting/neighbouring GLDB B.
• The reference point shall support information exchange between GLDB A and GLDB B to allow GLDB A to
obtain necessary information to determine the available spectrum for a CRS managed by GLDB A while
satisfying the protection requirements of incumbents registered in GLDB B under the regulatory domain of
GLDB B.

• The reference point shall support information exchange between GLDB A and GLDB B to allow GLDB A to
provide information about a CRS under its management to GLDB B to allow GLDB B to calculate the
interference to incumbents registered in GLDB B.
• The reference point shall support information exchange between GLDB A and GLDB B to allow GLDB A to
obtain information about the CRSs that are managed by GLDB B that affect the interference to incumbents
registered in GLDB A. Those CRSs may create interference below the interference reference field strength at a
given location probability of the incumbents that are registered in GLDB A. However, they may still
contribute adversely when considering aggregate/cumulative interference (see also section A11.1.1.4 of
ECC report 186 [i.2]).
