Personal Area Network – PAN

The communication network established for the purpose of connecting computer devices of personal use is known as the personal area network PAN (Personal Area Network).when a network is established by connecting phone lines to personal digital devices or PDAs (personal digital assistants), this communication is known as PAN (Personal Area Network). Thomas Zimmerman was the first research scientist to introduce the idea of Personal Area Network (PAN).

PAN (Personal Area Network) related technologies

The basic purport of establishing PAN (Personal Area Network) is provide a communication channel to the individuals, who want to carry their own digital devices .however at the same they want to stay in contact with the network. PAN (Personal Area Network) networks often cover an area of 30 feet. Personal computer devices may include palm tops mobile phones, potable media players, play stations and net books. These devices help a person to browse internet while traveling, to write notes and to send instant messages. These personal digital devices assist a person to develop networks and communicate via intranet, internet or even extranet. There are many wireless technologies which are helpful in developing wireless personal area network. Personal area networks (PAN) are developed either using cables or wireless technologies. Wireless PAN (Personal Area Network) is connected to the wired PAN (Personal Area Network) system either using fire wire or USB.

Wireless Personal Area Network (WPAN)

PANs (Personal Area Network)s are dependent on the Bluetooth or infrared technologies for the transmission of wireless signals. Blue tooth wireless PAN (Personal Area Network) is referred to as Pico nets. Pico nets are ad hoc networks. In this Pico nets network number of devices are connected by using Bluetooth technology. One key master device is further attached to seven or more than dynamic slave seven devices. Master device has a control and option to activate these devices at any time. Pico nets work over a range of 200metres and transmit data of about 2100 Kbit/ sec. the main focus point of wireless PAN (Personal Area Network) is to facilitate individual workspace. The Bluetooth technology used in wireless PAN (Personal Area Network) connection is based on IEEE 802.15 standard.

Wireless Personal Area Network (WPAN) can perform really efficient operations if we connect them with specialized devices. For examples it can help surgeons to seek guidance from other surgeons or team members during a surgical operation. Wireless Personal Area Network (WPAN) is based on plug –in technology. When wireless equipment’s come into contact with each other within the range of few kilometers, give an illusion if they are connected with a cable. Rapid development and improvement in this technology is needed in this area. This further development would help develop a seamless network between office and home devices. This development would help scientists, archeologists and people associated to other departments to transfer their findings to any database around them.

Purpose and uses of PAN (Personal Area Network)

The wearable and portable computer devices communicate with each other. These devices while communicating transfer digital signals and information, these signals are transferred using the electrical conductivity coming out of human body. This linkup information exchange can take place even between two people who are carrying digital assistance devices while they are shaking hands. In this process of hand shake, an electric field is generated around people, and they emit Pico amps. These emissions complete the circuit and hence an exchange of information takes place. This information exchange includes the transfer of personal data such as email address, phone numbers etc.

The purpose of PDAs is to make the use of electric field around human beings. Mobile phones (smart phones only), palmtops and even pagers serve this purpose. Wireless digital devices work twenty four hours a day and seven days a week. This enables you to stay in communication circle always. PAN (Personal Area Network) network has enabled the transfer of data within the small geographical areas with the help of many small and portable carrying devices.
