The high bit rate 802.11n consumes more power compared to other 802.11 modes during data transmission, reception, and idle (not transmitting or receiving high volume data) [1][2] and may lead to a shorter battery life in mobile devices [3]. This study investigates the transmit, receive, and idle energy consumption of 802.11 modes then forms a dynamic 802.11 mode scheme that uses different energy saving modes for different STA (Wireless Station) operations. The dynamic scheme energy consumption was compared against static schemes using a test bed that realizes seamless data communication during mode transitions. The results show that 802.11n is the most energy efficient mode to use in transmissions and receptions whereas 802.11g is the most energy efficient to use while idle. Therefore, the 802.11g-802.11n-802.11g dynamic mode scheme was formed and it was proven to be the most energy efficient scheme in ’30-second idle – 100 MB transmit – idle’ experiments whereas the static 802.11g scheme was proven to be the most energy efficient scheme in ’30-second idle – 100 MB receive – idle’ experiments.
