Access "Enterprise wireless connection policy: Navigating cellular vs. WiFi"
This article is part of the December 2011 Vol. 2, No. 6 issue of Revisiting past predictions for networking technology
Many of our wireless devices can connect to either a cellular data network or to a WiFi network. How do we make the cellular vs. WiFi decision for connecting enterprise devices? Cellular (3G/4G) data networks are ideal for on-the-go connectivity over a wide area, such as when moving outdoors. However, we've all experienced weak cellular signal indoors, which can cause slow or dropped data connections. Although outdoor WiFi networks are available in some areas, most WiFi hotspots are designed to cover a well-defined indoor space, such as a hotel, conference center, airport or airplane. As such, decisions about cellular vs. WiFi depend first on location and mobility. Increasingly, we will connect wireless devices to both network types and we may even roam automatically between them. By default, most smartphones prefer using WiFi, falling back to cellular only when WiFi is disconnected. Do you have a question for our experts?
