Wireless Personal Area Network (WPAN) is a type of computer network that is based on a specific geographical area. WPANs allow two or more devices to establish a wireless connection, usually within a range of 10 to 15 meters. WPANs are popular for various applications, such as connecting printers and computers or transferring data between computers and mobile phones.
WPANs use a technology called Bluetooth to allow the devices to communicate with each other without requiring cables or connections. Bluetooth relies on radio waves to transmit data, and it operates at a frequency of 2.400 to 2.4835 GHz. Bluetooth is a short-range wireless technology that is used to create what is known as a personal area network.
WPANs are used in many different consumer electronics, such as smartphones, tablets, and laptop computers, as well as game consoles and other devices. WPANs have also found their way into industrial applications, including machine-to-machine communication and point-of-sale payment processing.
WPANs are advantageous for several reasons. They allow for easy setup and provide connectivity without needing any cables or additional equipment. WPANs are also more secure than their wired counterparts since they use frequency-hopping technology and have support for authentication and encryption protocols. Additionally, WPANs consume less power than other wireless networks.
Despite their advantages, WPANs have their own disadvantages. The limited range of 10 to 15 meters makes them unsuitable for longer distances. In addition, WPANs are subject to interference from other wireless networks within their range and are susceptible to jamming.
