II. PAN(PERSONAL
AREA NETWORK) The idea of PAN was first given by Thomas Zimmerman and other researchers at M.I.T.'s Media Lab and later was supported by IBM's Almaden research lab.[20] PAN network is a computer network that allows devices to communicate around a single person. The network is structured for a single entity which can be in a small office, a building or apartment. PAN network connects different peripherals such as computers, telephones, video game consoles. PAN network can be wired or wireless such as USB, or they can be wireless, such as infrared, ZigBee, Bluetooth. [21]. It is a subset of LAN.The basic difference between PAN and LAN is that PAN supports individual person whereas LAN supports a group. [22]. The basic purpose of PAN (Personal Area Network) is to present a communication medium to the individuals, who want to carry their personal digital devices.[23].The area covered by PAN network is 10 meters.[1][2][3][4][18][19] International Journal for Research in Applied Science & Engineering Technology (IJRASET) ISSN: 2321-9653; IC Value: 45.98; SJ Impact Factor: 6.887 Volume 6 Issue III, March 2018- Available at www.ijraset.com 1179 ©IJRASET (UGC Approved Journal): All Rights are Reserved Fig. 1 PAN Network III. LAN(LOCAL AREA NETWORK) LAN is a privately owned network. It is largely used to provide connection between personal computers enclosed in a single building e.g. house, office, company, institutions, organizations etc. By providing connection between computers, it allows sharing of resources such as printers; data etc.LAN can be wired as well as wireless. Wired LAN is building mostly from point to point links using different topologies for transmission. Example of wired LAN is Ethernet. [18][10]. WLAN known as wireless LAN is the network that connects various nodes using wireless communication medium in a restricted area such as in a single building or office etc. The advantage of using wireless communication medium is that user can move freely in the network coverage area. Due to its easy installation process and easy use, it is widely used in homes, hotels, medical centres etc. It is based on IEEE 802.11standards and is known as Wi-Fi.[1][2][3] [5][6][7][11] TABLE I COMPARISON BETWEEN WIRED AND WIRELESS NETWORKS [24] Parameters Wired LAN Wireless LAN 1.Operational Speed High Low with respect to wired LAN 2.Cost factor Cheap as comparison to wireless LAN. Expensive 3. Installation process Complex and time consuming. Easy as comparison to Wired LAN 4. Bandwidth High Low 5.Transmission Media Copper cables, Fiber optic cables Infrared and radio waves. 6. Movability Limited Works in the entire wireless network coverage area.
