Wan Technologies

This paper will described all the different types of networks that are used in the world. I will describe the transmission distance and the new applications that will be out in the future. This paper will cover the WPAN, WLAN, WWAN, and WMAN.

A WPAN is a wireless personal area network which is a personal network for interconnecting devices that is used by a person’s work area. Usually a personal network will communicate within an average of 10 meters, which isn’t that far of a distance. Bluetooth is a perfect example of a WPAN because it is used in close range instances. An example of Bluetooth is something along the lines of a wireless ear piece connecting to a phone. This type of device will not work if it is out of range, similar to a wireless laptop connecting to a wireless network. The wireless persona

l area network uses the IEEE 802.15.3 which was formed early in the year 2005. The WPAN operates in the band using 57-64 GHz unlicensed band. The WPAN will allow high data rate over 2 GBps and applications like streaming a video over a high speed internet. It also has applications like real time sharing and wireless data bus for cable replacements. 60 GHz is a very well aspect to the WPAN but it can also be a problem with high directivity and high path loss. In the future applications of the WPAN, Toshiba plans to take advantage of the Bluetooth and make it possible for a user to open a garage door, and pass through toll booths on a road and to pay for gas for you. And last but not least to run diagnostics on a vehicle. These are all amazing future looks on what the WPAN can do for us users.

The WLAN is a wireless local area which is also referred to as LAWN. This is a type of network that uses high-frequency radio waves other than using wires to communicate between nodes. This type of network links more than two devices using a wireless method and it helps provide a connection through the access points. Now a user can freely move...
