Chapter 2. Understanding Wi-Fi > Related Wireless Standards

Related Wireless Standards

You might also hear about some other wireless standards, and wonder how they are related to Wi-Fi. The two other wireless standards you are most likely to hear about are Bluetooth and 3G.

Bluetooth is a short-range connectivity solution designed for data exchange between devices such as printers, cell phones, and PDAs. Like 802.11b, it uses the 2.4GHz spectrum. Although Bluetooth is built into a great many devices, it is a standard with some severe disadvantages, mainly that it is far slower than 802.11b (with nominal throughput of up to 721 Kilobytes per second) and with a maximum range of about 30 feet (compared to Wi-Fi's unamplified range of several hundred feet). Bluetooth's main claim to fame is that it is inexpensive, which is why it has been added to so many devices.
