Coverage area prediction for HDTV
Proceedings of APCCAS'94 - 1994 Asia Pacific Conference on Circuits and Systems, 2002A coverage area prediction method developed in TL (Telecommunication Laboratories) is introduced. The program uses a simple method to predict the signal interference and coverage area automatically and quickly. This technique helps us to re-allocate the site and frequency of radio stations efficiently, especially useful for the advent of HDTV.

Coverage Contribution Area Based $k$ -Coverage for Wireless Sensor Networks
IEEE Transactions on Vehicular Technology, 2017Coverage is a primary metric for ensuring the quality of services provided by a wireless sensor network (WSN). In this paper, we focus on the $k$ -coverage problem, which requires a selection of a minimum subset of nodes among the deployed ones such that each point in the target region is covered by at least $k$ nodes.

Radio Broadcast Coverage of City Areas
Transactions of the American Institute of Electrical Engineers, 1926l. Radio broadcasting involves a system of electrical distribution in which dependent relations exist between the transmitting station, the transmitting medium and the receiving station. 2. The attenuation and fading which attend the spreading out of broadcast waves are considered.

Multiple UAV area decomposition and coverage
2013 IEEE Symposium on Computational Intelligence for Security and Defense Applications (CISDA), 2013Multiple UAVs can be used to cover a region effectively. Area coverage involves two stages - area decomposition into cells and path planning inside the cells. The area is decomposed using sweeping technique. For path planning inside the cells, a novel method is developed where optimal number of lanes are generated to minimize the number of UAV turns to
