Low Cost Extended Wireless Network Using Raspberry Pi 3B+

This paper presents a development of a low cost extended wireless technology and its performance at a low coverage area. Raspberry Pi 3 B+ is configured and programmed to act as the access point of an existing WIFI network. During the testing, various aspects are considered and analyzed such as the energy efficiency of the Raspberry Pi and also the signal strength of the network. The measurements results show the effectiveness of Raspberry Pi in extending the network signal up to 80 meters distance especially in the free space environment. This method can be an alternative way as it can act as the temporary signal network at a place that has a low network signal.
