The graphical tool for TV white space deployment has the following options:
Select Base Station Information - This is used to select the locations for determining the TVWS antenna placement. It has two options.
- Import Raw Data - User can import base station information from .csv file according to a pre-defined format.
- Auto Pick Input Locations - By selecting this option, the base station information is imported automatically.
Select Metric of Measurement - It provides the user three metrics for TVWS antenna placement.
- Coverage - Antenna locations are picked according to the geographical coverage area of the potential location.
- Population - Base stations for deploying the TVWS antennas are selected in order of decreasing population.
- Weighted Utility - Metric developed by us, which picks locations based on coverage-population tradeoff.
Select Propagation Model - Four propagation models are currently supported by the tool.
Theoretical Model Parameters - These parameters are used in calculating the theoretical model throughput as per Shannon's theorem.
- Receiver Sensitivity (dBm) - Power level at the which the end-user can detect the RF signal.
- Transmit Power (dBm) - Power of the TVWS transmitter.
- TVWS Frequency (MHz) - Frequency at which the TVWS antenna operates.
- Channel Width (MHz) - Breadth of the TVWS signal for transmission.
When the user executes the theoretical model, the locations at which the TVWS antennas should be setup are displayed. On hovering over the antenna markers, one can observe all the information related to the antenna site such as latitude, longitude, altitude, coverage radius, users served, and the weighted average throughput of the antenna deployment.
This tool is the outcome of ongoing EU-India REACH project in CSE department at IIT Bombay. It can be used by researchers and network engineers to plan the deployment of TV white space antennas. The tool models Thane (India) district, which is characterized by rural demography.
