Many people seem to think that WiFi technology is reserved purely for wireless broadband internet access, but in actual fact, it has been put to many other purposes as well. For example, WiFi phones are built to allow for wireless roaming within a limited area (e.g. a home or office). This useful technology standard has also been used in conjunction with VoIP telephony in the production of wireless VoIP phones. Another use of WiFi is in the handheld computing market. WiFi PDAs are becoming more and more common, and can sync with computers and other devices easily, and without the inconvenience of messy tangled wires. Of course, as with all communication devices, you should always ensure that you have the proper WiFi security features enabled in your wireless communication tools.
