To provide a better perspective of Wi-Fi, this page shows how it compares to other wireless technologies. The graph on the left, shows the range of each technology. Wi-Fi has a typical range of 100 meters which in a real-world situation equals about the range of a house. Also shown, are low energy technologies like Bluetooth and ANT which have a range closer to 10 meters or about the range of a large room. However, a big factor in range is whether a power amplifier is used with the radio. Regarding data rate or maximum throughput, Wi-Fi has the greatest throughput with up to 72 Mbps for 802.11n. Compared to other technologies, Wi-Fi has a higher power consumption but this is because it offers the highest data rates. Typically, portable Wi-Fi devices run on a lithium ion battery. However, depending on the data rates and how often data is sent, its also possible to use lower power sources such as AAA batteries.
