Example of network coverage estimation method
Maximum communication radius [km] of TVWS network
shows estimation function of :
Using modeled equations
Example models can be seen in Eqs.(4.3) and (4.4) [6]
X shows the class of loss factors such as its path loss, shadow fading effect and so on.
The path loss model can adopt propagation probability curves like FCC rule [4][5]
Y shows the class of gain factors such as the antenna gain, beam-forming gain and so on.
Z shows the class of network configuration parameters for the calculation of this estimation function such as the transmission/receiver antenna heights and so on.
shows maximum transmission power of TVDB (TV Band Device)

Categorization of coexistence network configuration (1/4)
Class#1
Two different TVWS network coverage areas overlap each other. Each master node can communicate each other via wireless if the same RAT (Radio Access Technology) or/and the same operation channel is/are used(*1).
P system
(*1)This depends on the RAT functionalities.
TVWS network #1
TVWS network #2 .

Categorization of coexistence network configuration (2/4)
Class#2
Two different TVWS network coverage areas overlap each other. But each master node cannot communicate each other even if the same RAT and the same operation channel are used. However, some of slave nodes can communicate each other via wireless if the same RAT or/and the same operation channel is/are used (*1).
P system
(*1)This depends on the RAT functionalities.
TVWS network #1
TVWS network #2

Categorization of coexistence network configuration (3/4)
Class#3
Two different TVWS network coverage areas do not overlapped each other. Each master/slave node cannot communicate each other even if the same RAT and the same operation channel are used.
P system
TVWS network #1
TVWS network #2 .

September 2010
Categorization of coexistence network configuration (4/4)
Class#4
Two different TVWS network coverage areas are overlaid each other. The “overlaid” means here that a smaller area TVWS network exists in a wide area TVWS network. In this case, each master/slave node can communicate each other via wireless if the same RAT or/and co-channel is/are used (*1).
P system
(*1)This depends on the RAT functionalities.
TVWS network #1
TVWS network #2
