摘 要：The goal of this project is to develop an Android Phone App that can be used to measure dimensions of a room and overlay it with a Wi-Fi strength map. This is meant to address suboptimal arrangements of Wi-Fi router/access points, which result in a low speed/unstable/inaccessible Wi-Fi signal coverage in an indoor space. The motivation of the project is to reduce the cost of having a specialist to come to customers property to x Wi-Fi coverage problems. The App developed will enable Android users to identify such problems themselves for free.
