Wireless Networking - 3 Summary on What we have studied in last Tutorial  :- IEEE 802.11 :  Released in year 1997, this is the original version of 802.11 standard. It has a typical data rate of 1Mbps and maximum of 2Mbps in the 2.4 GHz band. IEEE 802.11a :   Modified in the year 1999. this is the improved version of the original 802.11 standard. The 802.11a standard operates in the 5 GHz band and uses 52-subcarrier orthogonal frequency-division multiplexing (OFDM) for signal generation. IEEE 802.11b :   This standard was also released in 1999. It has typical data rate of 6.5 Mbps and a maximum data rate of 11 Mbps in the 2.4 GHz band. The media access method used here is also Carrier Sense Multiple Access with collision Avoidance (CSMA/CA). IEEE 802.11g :   This standard was released in June 2003. It has a typical data rate 0f 22Mbps and maximum data rate 54Mbps in a 2.4 GHz band. The indoor range is 30 m. IEEE 802.11n :  This is the latest version of IEEE 80

Wireless Networking - 2 Summary on What we have Studied in last Tutorial  :- Wireless technologies allow one or more devices to communicate with each other without any physical connections such as cables. Wireless networking allows you to establish a communication between two or more computers. The communication is established using radio frequency (RF) and without the use of cables. Wired Networking requires cables to be connected to each and every computer in the network. It becomes difficult to run cables through walls and under the floor making it time consuming. Wireless Network can be configured in two ways: Ad hoc or infrastructure mode. Reliability of wireless network is less as compared to wired network. The main concern in wireless networks is interference from appliances using same frequency spectrum. However, with the proper installation the interference can be minimized. The different wireless standards that are used in wireless networking are IEEE 80

Wireless Networking - 1 Chapter Objectives :- Compare Wireless and wired network Explain different wireless standards Components required for wireless networking Different types of wireless networking bands Setup a wireless network Troubleshoot wireless network problems Various applications of wireless networking Introduction  :-       Wireless technologies allow one or more devices to communicate with each other without any physical connections such as cables. Wireless technologies use radio frequency transmission for transmitting data. Using wireless network data can be transmitted between a wireless computer and a wired computer. Users need not disconnect their laptops, instead they can around the office and perform their tasks effectively. There are advantages of using wireless networks over wired networks like setting it up and freedom from cable connections . (1) Wireless Networking Basics  :-          Wireless networking allows you to establi
