The portability of the network and consistent contact with the wired network in a setting assists users for unlimited access to data. (Gilb, 5) The drawback of Radio Frequency method of networking is its short distance coverage and more energy requirements
If the networking is set in an office or house, it may need more resources for fixing the connection. (Gutierrez, Jose a; Callaway, 7) Another benefit of WSN is the minimum damage or repair
11b connected computer in a common area with a card and an antenna can enhance connectivity to all computers in the vicinity. (Vickery, 230) This is however a threat to Internet Service Providers where individual connections can be used to serve more users by breaching the restrictions of use
Recently the Bluetooth and Infrared protocols have been introduced and it offers very short-range connectivity services and these systems are known as wireless personal area networks or WPAN. (Andress, 2003) We know that Wireless local area networks which enable e-commerce but are vulnerable at having information hacked into
In some instances IPSEC authentication methods and encryption for level 2 is a must. (Gast, 2005) Wireless LAN is finding increasing applications in all aspects of human life
It is possible to provide, using distributed antennas, "powerful benefits of space diversity without need for physical arrays and needs." (Laneman; Tse; Wornell, 2004) Security features today include the SSL or secured layer protocol, and the PPL or point to point protocol but for wireless applications like Bluetooth and the cell applications, new systems have evolved for creating security
This technology also enables the identification of mobile phones and radio-based communication devices which enable the spread and reach of e-commerce and secure payment and banking transactions. (Macphee, 2001) Wireless network have now become widespread
This is the standard layer security which evolved into the SSL or Secure socket layer. (Nichols; Lekkas, 2002) the important factor to consider while selecting a protocol is to see which layer needs security
11b. (Paukkunen, 1999) Some standards like the blue tooth are new, the wireless field is exploding and new and better protocols based on application requirements are being released day by day
There must be supporting hardware to go with this system at both the server end and the terminal end. (Sklavos; Kitsos; Papadopoulos; Koufopavlou, 2006) Security threats come in many forms
16 standard for air interface is also called IEEE Wireless MAN air interface. (Bedell, 474) The application of IEEE Wireless MAN air interface is essentially in multimedia where the wireless network covers a distance of up to 30 miles where wireless solution can be provided in the most complicated situations
This is also called a campus network. (Kumar; Parameswaran; Jayalakshmi, 177) the function to operate and transmit data by Microwave Access Forum is abbreviated as WiMAX
These signals enable LAN to operate approximately in any place. (Ouellet; Padjen; Pfund, 2) One of the most advantageous features of WLAN is the connectivity required in a conference hall
It is technically preserved through encryption and integrity of information transmitted is maintained through digital signatures by using methods for key refresh, key exchange and bootstrapping. (Sankar, 10) fundamental knowledge about LAN would assist to learn more about the functioning of a WLAN
The knowledge of this mechanism is vital for the successful installation and operation of a WLAN. (Trulove, 18-19) An understanding of the difference between LAN and WLAN is also essential to install WLAN
Cable modems began to replace dial-up modems and hard-wired routers on a more widespread basis in 1999, which offered business computing the advantages of tremendously increased speed, (by approximately a factor of five), as well as the interconnection of multiple computers within a single network sharing a single high- speed Internet connection. The first generation of wireless computer connection hardware was introduced by 3 com, but the technology was still too expensive for many business and individuals contemplating the upgrade from hard-wired connections to wireless networking (Briere, 2003)
The hardware of the era was very difficult to configure with its corresponding software, and far beyond the technical capabilities of non-expert installation and maintenance. As a result of the high price and complicated, temperamental nature of establishing the first generation of wireless networking equipment, most users opted for digital subscriber lines (DSL), because they boosted speeds considerably, over the fastest data transfer rates then achievable through dial-up modems over telephone lines (Franklin, 2007)

Fiber Optics and Wireless Systems in Wide Area Networks Fiber Optics and Wireless Systems in Wide-Area Networks The use of Fiber-optic technologies in Local Area Networks (LAN) and wide-area networks (WANS) is becoming increasingly necessary for optimizing data-intensive application development and use. The use of large-scale database management programs and initiatives including Hadoop, MapReduce and other large-scale data management initiatives continue to escalate the use of Fiber-optic networks in LAN and Wan implementations (Arnold, 18)
