The power consumption of a wireless device depends on multiple factors:

• The amount of data transmitted and received
• Duration of the device’s airtime versus its sleep time
• Geographic coverage and range of its wireless network
• Wireless protocols which enable low power and low data rate transmission
• And most importantly, the RF performance of the device's antenna 

This white paper will provide a thorough discussion on how the RF performance of an antenna impacts the power efficiency of the wireless device.
