How Does Wi-Fi Use Affect Computer Battery Life? tyson 29-October-2008 11:48:22 PMComments http://www.uwidonews.com/News/Can-a-use-of-Wi-Fi-Affect-Computer-Battery-Life/related_links Posted by saqlain231 YES-The Wi-Fi network protocol requires electric power to operate the radio transceivers used to send and receive data. Posted by waqasahmad Simply YES Posted by HamidAliKhan Yes the Wi-Fi net protocol requires electric power to operate. Posted by waqqas1 The Wi-Fi network protocol requires electric power to operate the radios used to send and receive data. Using Wi-Fi on a computer or handheld device can significantly increase its power consumption (shortening battery life). Posted by mariuspaul The power required by a Wi-Fi radio is measured in decibel millwatts (dBm). Wi-Fi radios with higher dBM ratings tend to have greater reach (signal range) but will generally utilize more power than those with lower dBM ratings. Wi-Fi consumes power whenever the radio is on. With older Wi-Fi network adapters, the amount of power used is generally independent of the volume of network traffic sent or received, as these systems keep the Wi-Fi radio powered at all times even during times of network activity. Newer Wi-Fi systems that implement the WMM Power Save power saving intelligence may according to the Wi-Fi Alliance save between 15% and 40% over other Wi-Fi systems. On Linux, the LessWatts.org initiative has also created its own Wi-Fi Power Save Poll protocol that intelligently powers off the network adapter for short periods of time to save energy. A relatively new technology, using solar energy to power Wi-Fi routers is also an area of active research and product development. Overall, the battery life (the length of uninterrupted operating time possible with one full battery charge) of Wi-Fi devices varies depending on several factors including: * the type of battery installed * the dBm rating of the Wi-Fi radio (network adapter) * how often the Wi-Fi radio is turned off versus on * Wi-Fi power savings modes available on the device * the power needs of the display (screen), processor and other elements of the hardware separate from Wi-Fi Posted by sagitraz |
