This method had the added benefit of saving battery power by turning off radios when they aren't needed. By powering off the radios that you do not want to use, Connection Manager is forced to use only the connection that remains. Control power to radios that aren't needed or aren't in use.In this blog I will explain some best practices when dealing with multiple connections and then provide some details on implementation. Leaving all radios active at all times can have a detrimental effect on battery performance with little to no gain. There are also power considerations when dealing with multiple radios. This works well in most cases however there can be situations where the best suited connection for the customer is not the "least cost" connection as decided by Connection Manger. Typically it will prefer wired Ethernet to wireless LAN and wireless LAN to cellular. The Microsoft Connection Manager ( ) is responsible for handling connection requests from applications and automatically deciding the "least cost" interface to use. Windows Embedded HH 6.5 allows multiple interfaces to be up simultaneously and will allow the device to have multiple IP addresses. To add to that, these can be connected independent of each other or all at the same time. The devices can be connected through wireless LAN, cellular, Bluetooth, and even wired Ethernet.

Handheld devices in enterprise environments typically don't use a single network connection for communication.
