Introduction to Wireless LANs

We will discuss about the market share of wireless LAN, a description of past, present and future of wireless LAN, wireless LAN and the introduction of government standards. Then we will discuss some applications for wireless LANs. According to the experience of the story and evolution of wireless LAN technology is an important part of the basic principles of wireless LAN. An understanding of where wireless LAN and its application and the organization come to help the development of technology that allows you to apply a better wireless LAN into your organization or client needs.
Wireless LAN Market Share
Wireless LAN market share seems to grow as well as fashion in most network industries, starting with the early adoption of any technology that has been available. Marketing has moved into rapid growth, where the popular standard provides a catalyst. Large difference between the overall network marketing and marketing of wireless LAN can be increased. wireless LAN, providing flexibility in implementation and no wonder they moved quickly into other market sectors.

History of Wireless LAN
The spread of wireless networks, like many technologies, such as hereditary under the auspices of the military. The military needs a convenience, easy to implement, and data exchange security method in an environment of war.
As costs decline and quality of wireless technologies increases, it becomes cost savings for companies that can incorporate the wireless into their networks. Wireless technology offers a cheap way to campus to connect buildings to each other without fiber or copper cabling.

The standardization of wireless LAN
Since wireless LAN uses radio frequencies to send, the wireless LAN is governed by the same type of law and used to regulate things like AM / FM radio. Federal Communications Commission (FCC) regulates the use of wireless LAN equipment. In the wireless LAN market today, receive some operational standards and requirements in the United States are created and maintained by the Institute of Electrical Electronic Engineers (IEEE).
Some wireless LAN Standard:

IEEE 802.11 - the original wireless LAN standard set of data transfer rate of the slowest in the transmission of light-based technologies and RF.
IEEE 802.11b - describe about some of the faster data transfer and more limited in scope transmission technology.
IEEE 802.11a - image of sending data faster than (but less in accordance with), IEEE 802.11b, and use the 5 GHz UNII frequency bands.
IEEE 802.11g - the most recent terms, based on the 802.11 standard that describes the same with the faster data transfer such as IEEE 802.11a, 802.11b and in accordance with which allows for cheaper.
IEEE 802.11n-2009 is an Amendment to the IEEE 802.11-2007 wireless networking standard to improve network throughput over the previous two standards - 802.11a and 802.11g - with a significant Increase in the maximum raw data rate from 54 Mbit / s to 600 Mbit / s with the use of four spatial streams at a channel width of 40 MHz.

Since 2007, the Wi-Fi Alliance has been certifying interoperability of "draft-N" products based on what was of the IEEE 802.11n draft 2.0 specification. [3] The Alliance has upgraded its suite of compatibility tests for Some enhancements finalized after the draft 2.0 . Furthermore, it has affirmed That's all certified draft-n products remain compatible with the products conforming to the final standards.
