For many years now, voice calling over the internet has become accessible to consumers thanks to the increasing amount of applications utilizing the capabilities of the internet. With the decreasing costs of wireless networks, consumers can now access the internet almost anywhere. While network providers offer various options for our daily network usage, our project focuses on two most popular choices: Municipal WiFi and 4G LTE. Municipal WiFi is a large wireless access area consisting of many WiFi hotspots. Customers can access the Internet through thousands of these wireless hotspots as long as they are within coverage range. However, 4G LTE is currently the most popular wireless data communication technology for mobile devices, and may be accessed anywhere within the network providers' range of services. The goal of this project is to examine the delay, jitter, and packet loss of the two technologies while voice calling in order to compare the advantages and disadvantages of each technology. We plan to measure performance by creating more realistic simulation scenarios by using various network loads as well as by varying the distance from the signal source.
