By 2016 more users are expected to access the Internet using mobile devices than laptops and desktops. Mobile broadband usage is extremely important and there are both new and existing network standards that enable users of mobile devices such as smart phones and tablets to access the Internet. Healthcare related applications and services are being deployed through smart phones and other mobile devices through wireless networks that provide solutions for disease management tools and aid in remote diagnosis. Mobile device users view speed of access as one the most important metrics when selecting a broadband service provider. Today mobile device users are faced with a choice of different wireless network standards including Wi-Fi, 4G, and 4G-LTE. This research quantifies the difference in performance seen by mobile users using current network standards. The research provides a detailed vendor-neutral study of the performance characteristics of these three network standards. It uses an iPhone 5 as the mobile device for the experimentation. By keeping the mobile device constant, the network standards are varied and various metrics such as response times and data rates (throughput) are measured. The study captures response times for accessing well-known web site pages as well as downloading data files of various sizes by varying the network standards one at a time, both indoors and outdoors. The research shows that 4G-LTE network has the fastest download and upload data rates, followed by Wi-Fi, with 4G the slowest for mobile device access. Statistical analysis using T-TEST confirms that 4G-LTE provides faster response time as compared to 4G for mobile device access (p < 0.05). 4G-LTE supports smooth streaming of live video and audio and is a vital technology for mobile devices.
