What is PAN Network? PAN network stand for personal area network.In this network all the personal devices are connects to form network.Its range is 10 meters to 33 meters.All devices should be in this range to form network.This is not different form what is WAN network?But devices,node,range make it different form WAN,LAN,MAN network. Some personal device are,laptop computer,mobile phone,cellphone,PDAs,printer etc.It is also called WPAN (wireless personal network).It is always uses to communicate all personal device with each other.But some it is use to connects with higher level network.But they need gateway to connect. A personal area network are wireless or wire interfaces. Technologies Use to Build a PAN: This network can be wireless or form by cables.Mostly U.S.B and Fire-wire are link together to form PAN network. While WPANs use Bluetooth or infrared connections. Diagram of PAN Network Bluetooth WPAN: Bluetooth is uses for short-range radio wav...

Wireless LAN is made by connecting different devices through wireless communication to make a local area network.  WLAN  follows a standard named IEEE 802.11. WLAN connects laptops, smartphones, personal digital assistants, desktop computers, workstations and printers. This network is easy to install and use at the home or any other place. WLAN include an access point (AP) which is used to connect to the internet. AP sends and receives radio frequency signal to the connected devices. In 1990 WLAN installation was expensive and was only deployed where the wired connection was not possible. In the late 1990s, cost decreases to implement WLAN because of using IEEE 802.11 standard. It works with a bandwidth of 2.4 GHZ (802.11b) or 5 GHZ (802.11 a). The devices which WLAN connects are also called clients. WLAN gives a high data transfer rate. It uses star topology in which all nodes send/receive data through access points. It works better in homes and offices. Especially in of...
