![]() The ubiquity of mobile videoconferencing apps is partially the result of enhanced microprocessor capacities making it possible to videoconference with software, rather than special dedicated hardware. They are more scalable and flexible and thus are distinctively different from traditional, stand-alone hardware-based videoconferencing devices. Cloud videoconferencing systems are software-based, with client apps designed to take advantage of microphone and camera capabilities built into or added onto local computing devices to access software on servers providing services managing communication. Mobile videoconferencing apps are a form of cloud computing, where locally installed client software communicates over networks with programs on servers providing services. Mobile videoconferencing applications (apps) enable consultations between healthcare providers and patients from any location, even while in transit, using data-capable mobile devices with cellular or Wi-Fi access. ![]() App performance increased over the testing period due to improvements in network infrastructure and how apps manage bandwidth. Conclusions: Apps for mobile devices can vary significantly from other videoconferencing software or hardware. The platform, network, and apps interact, and it is impossible to discuss videoconferencing experienced on mobile devices in relation to one of these factors without referencing the others. Results: Findings are discussed in relation to operating system platform (iOS or Android) for which the apps were designed and the type of network (Wi-Fi, 3G, or 4G) used. ![]() The rationale for app assessment and the testing methodology are described. Materials and Methods: The tests were done to determine how well apps perform compared with videoconferencing software installed on computers or with more traditional videoconferencing using dedicated hardware. Introduction: The quality and performance of several videoconferencing applications (apps) tested on iOS (Apple, Cupertino, CA) and Androidâ„¢ (Google, Mountain View, CA) mobile platforms using Wi-Fi (802.11), third-generation (3G), and fourth-generation (4G) cellular networks are described.
