Feature #1: Determine Location
Explore how to identify the furthest location within a cellular network where a handset remains functional despite signal loss. This lesson teaches you to analyze a 2D signal loss matrix and implement an efficient search strategy using binary search principles, optimizing signal coverage analysis with minimal computational complexity.
We'll cover the following...
Description
Using a base station located in the top left corner, a cellular operator serves a rectangular region. They have done a road test where they measured the strength of the signal received from their network in a rectangular region. They recorded the loss in signal strength perceived at various parts of the region. The signal loss increases when you move towards the right of the region. The signal loss also increases as you move vertically towards the bottom of the region. To do this, the operator targets a specific handset that works as long as the signal strength does not fall below a certain threshold value. We want to determine the farthest point from the base station within this rectangular region where the handset will work.
We’ll be provided with a 2D matrix consisting of signal strength loss values and a threshold loss value. We need to determine the furthest location beyond which the handset will ...
