A mobile device may include a Wireless Local-Area-Network (WLAN) communication unit to communicate with an Access-Point (AP) of a WLAN, e.g., a mobile hotspot; and a Personal-Area-Network (PAN) communication unit to locally communicate with one or more peripheral devices, e.g., mice, keyboards, or displays, and the like.
In order to maintain a connection to the WLAN, the mobile device must keep the WLAN communication unit active, which may consume a relatively large amount of power. In order to reduce power consumption, a user of the mobile device may manually disable the WLAN communication unit. However, disabling the WLAN communication unit will result in disconnecting the mobile device from the WLAN.
Some mobile devices implement power-save modes to significantly reduce power consumption. However, even the power-save modes may require the WLAN communication unit to be at least partially active, e.g., to employ a carrier-sense multiple-access (CSMA) mechanism.
