What is Wireless Broadband tutorials

  • Wireless broadband is technology that provides high-speed wireless Internet access or networking access over a wide area.

  • Windows 7 provide same user interface regardless or service provider. However in order to use wireless broadband, you need to have wireless NIC adapter and Wireless Modem/Router.


Security Protocols for Wireless Network.

  • In order to protect Wireless Network from unauthorized users, various wireless Security Protocols are developed. In addition to preventing uninvited guest from connecting to your wireless network, wireless security protocols encrypt your private data transmitted over the wireless.


Point to note:-

  • In early days wireless networking manufactures tried to make wireless networking equipment easy but insecure.


Wireless networks are inherently insecure! Why?.

  • Wireless network are generally not as secure as wired networks. Wired networks send data between two points, which are connected by network cable. On the other hand wireless network broadcast data in every direction. These wireless data may propagate beyond the physical boundary of office or home to every device that happens to be listening.

  • In order to protect your Wireless Network, you must configure Authentication and Encryption option.



  • In simple word Authentication verifies who you are.

  • It requires you to provide valid user credentials such as User name and Password or proof with authentication key.

  • It prevents unauthorized users from joining your wireless network.



  • Encryption sends the content of all wireless data in encrypted format so only receiver can interpret its content.

  • Encryption prevents unauthorized users from retrieving sensitive data.

  • It also helps in preventing unauthorized user from sending valid frames and accessing your private wireless network.

  • Wireless LAN supports following security standard. Each standard have own strength and weaknesses.

Strong Authentication using Strong PSK and TKIP.

Very Strong AES Encryption

Used for Home & Small Co.


WPA (Wi-Fi Protected Access) and WPA2 (Wi-Fi Protected Access 2) are available in 2 modes:-


  • It is used for Home and Small Organization.

  • In this mode a Pre-shared key or passphrase is used for authentication.

  • A pre-shared key is used for authentication and is provided to each users.

  • This pre-shared key is dynamically sent between Access Point and Clients.



  • It is used for medium and Large organization.

  • This mode includes all the features of WPA Personal plus support for 802.1x RADIUS authentication.

  • It can be used only where RADIUS server is installed and Server distributes individual keys to users that have wireless designation.
