• Performed a major role in the Wireless Communication design, Development, Testing and deployment of the TV-Whitespace Technology which use Geo-Location Database to allocate the Unused TV whitespace channels to the requesting Whitespace Device.
• Unused TV channel allocation based on minimum path loss and minimum Interference/Noise. Hata model is used for the calculation of pathloss and assigns a TV whitespace channel with allowed transmission power for every WSD.
• Interference Management which includes co-channels and adjacent channel interference calculations based on the channel gain, path loss and geo-location details. This provides the channelquality factor from minimum interference values to maximum interference values.
• Experience in Web API development using Java and C#. This Web API simulator allows to simulate the communication between the Wireless device and the GLDB.
