Type of Technology of Wireless Local Area Network - Report Example

Wireless Local Area Network Wireless Local Area Network represented by (WLAN), is a network that operate wirelessly and act as a link between two or more devices that are compatible with the wireless system. This type of technology has played a very vital role in simplifying networking without major interruptions by allowing simultaneous linkage and resource sharing within a given area whether an office or a home. Sharing of numerous resources has been realized including; video and audio streaming, internet connections, file sharing and network printers. This type of procedure has become quite dominant because with computers carrying potentially diverse operating systems as well as marginal hardware, users have changed their habits of using the lone functioning computers to networks operating on compound computers. More laptops have continually attracted massive sales compared to the desktop computers because many people have turned away from the use of wired connections to WLANs. Users can easily connect to any internet network wherever they are without any difficult, whether at home, school, office or bookstore. This article seeks to examine how the WLAN operates, its importance in the society and the impacts it has brought. Wireless LANs in the Office The most suitable solution for a network administrator is network in all respects. Cable installation in every workstation is no longer necessary nor is it a requirement. Wireless networking sets ground for many businesses meetings to be carried out impromptu in such places as cafeterias, courtyards or wherever the partners are comfortable with and deem it is the right time for the meetings as well as provide LAN for business applications such as light file sharing, communication and conducting research. Wireless LANs in the home With massive reduction of prices of wireless networking, it has become a routine for wireless networking products to be transported from workplaces to homes. Wireless network offers easy and free lifestyle to in terms of conversation, exchanging data and music or video with user across the Internet and around the world. Home users can develop a wireless network out of an existing wired network and wirelessly spread the scope of the Internet all over the home on numerous computers, making it more appropriate for everyone to access the internet. Types of WLAN Technologies Several networking technologies have developed over time, therefore, resulting to systems such as Narrowband, spread spectrum, frequency hopping range and direct system spread band. Narrow band This is a type of technology that uses a particular radio frequency within the range of 50 cps to 64 Kbps for file transmission. Spread Band This system of technology was initially developed purposely for military use, it permits for more bandwidth by recurrently modifying the frequency of the communicated signal, therefore, spreading the broadcast across several frequencies. Spread band uses extra bandwidth compared to narrowband, although the broadcast is more protected, consistent, and easily detectable. Frequency Hopping Spread Spectrum (FHSS) Frequency hopping spread spectrum (FHSS) system harmonizes the changing rate of both the source and receiver by means of a narrowband transporter to efficiently produce a particular transmission signal. This rate could occur as often as numerous times a second; it constantly fluctuates from one occurrence to another, relaying data for a definite period time before repeating the same sequence. Similar to spread band system, FHSS technology ingests extra bandwidth; however, this is over the course of multiple carrier frequencies. Direct Sequence Spread Band Direct sequence spread band system breaks down the transferred stream of information into minor fragments through a frequency. A dismissed bit array known as a chipping code is created for each bit transmitted. In general, the length of the chipping code determines originality and the quality transmitted that is, the reception of data will be prompt and proper. This technology consumes more bandwidth than Frequency Hopping Sequence band, but Direct Sequence band is deemed more dependable and resists interference. Because of the chipping code, information can still be retrieved without a communication of the same signal. United States Robotics wireless network outcomes utilize Direct Sequence band technology. Wireless LAN Rate Uses The 802.11 b regular defines 14 frequency stations suitable to this technology. There are certain administrative limitations for firms offering these products and consumers depending on the country of residence. Wireless Network Components Much like an old-fashioned wired LAN, a WLAN is a combination of computers and marginal devices that share a common communications support. WLAN enables users to link to the LAN wirelessly through radio communication. Access Point is a computer device that links a radio system to a wire connected LAN. It intensifies the operational array of a wireless system and provides supplementary network administration and security structures. Wireless systems of three or fewer computers do not need an access point. Access points are valuable for superior networks, and they are, above all, suited for improving wireless ability to a prevailing wired setup. The United States Robotics22 radio Access Point links through an RJ-45 cable to a Local Area Network and has the ability to support 20 wireless operators effective radius of about 1500 feet in open areas. It also accelerates extra security features such as MAC address authentication. Computer Card This is a system that empowers laptop handlers to link wirelessly to the Local Area Network. United States Robotics22 Mbps Wireless computer Cards permit commercial networking of between one and three workstations effectively within an open range of 1000 feet. The same way a wireless access, a computer card allows the accessibility of portable and laptop devices to the Local Area Network, a PCI device permits desktop workstation operators access the Local Area Network. United States Robotics 22 Mbps Wireless PCI Adapters permit for commercial networking of between one and three workstations at an effective radius of up to 1000 feet in an exposed area. Router This is a crucial device used for distributing a particular Internet link across several Computers. This is ultimate in home an office where many computers and devices are simultaneously online with only one source of internet connection. Conclusion Conclusively, the WLAN system of network is the latest and the most improved technology. It is the fastest and more efficient than the other forms of network systems available. Regardless of the challenges it may face in terms of insecurity, it is portable, and it makes it simple for its user to conduct their day to day activities with plenty of ease.
