One to Many Communication Essay

What is wi fi ?Wi-Fi is the name of a touristed wireless mesh topologying technology that uses radio waves to go forth wireless high-speed internet and net income connections. A common misconception is that the full term Wi-Fi is short circuit for wireless fidelity, however this is not the case. Wi-Fi is evidently a trademarked term heart IEEE 802.11x. The wi fi shackle, the organization that owns the Wi-Fi (registered trademark) term specific exclusivelyy defines Wi-Fi as every wireless local scope internet (WLAN) products that argon ground on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standards. Initially, Wi-Fi was used in place of only the 2.4GHz 802.11B standard, however the wi fi alliance has expanded the generic use of the Wi-Fi term to include both type of electronic meshwork or WLAN product based on any of the802.11 standerds, including 802.11b,802.11a, dual good deal ,and so on,in an attempt to stop sloppiness about wireless LAN int eroperability.How Wi-Fi workings?Wi-Fi works with no physical wire connection between sender and telephone receiver by using radio frequency (RF) technology, a frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF menses is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space. The cornerstone of any wireless network is an access aim (AP)The primary job of an access stay is to broadcast a wireless request that computers can detect and tune into. In order to connect to an access destine and join a wireless network, computers and devices mustiness be equipped with wireless network adaptersWi-Fi Support?Wi-Fi is supported by more applications and divecesincludingvidio gameconsoles, home network, major operating(a) system, and other types of consumer electronic .any products that are tested and approved as Wi-Fi Certified (a registered trademark) by the WI FI alliance are certified a s interoperable with each other, even if they are from different manufacturers. For example, a user with a Wi-Fi Certified product can use any post of acess point with any other brand of client ironware that also is also Wi-Fi Certified.Wi-Fi hamper?The Wi-Fi bond paper is a trade connexion that promotes Wriless LAN technology and certifies products if they conform to received standards of interoperability. Not every IEEE 802.11-compliant device is submitted for affidavit to the Wi-Fi Alliance, sometimes because of costs associated with the certification process. The escape of the Wi-Fi logo does not necessarily criminate a device is incompatible with Wi-Fi devices. The Wi-Fi Alliance owns the Wi-Fi trademark. Manufacturers may use the trademark to brand certified products that belong to a variance of wireless local area network (WLAN) devices based on the IEEE 802.11 standards.Advantages Flexible if on that point is ad-hoc situation when additional workstation was requi red. Implementation cost is cheaper than wired network. Ideal for the non-reachable places such as across river or mountain or rural area. Ideal for temporary network setups.Disadvantages Lower speed compared to wired network. (of course of study) Less secure because hackers laptop can act as Access Point. If you connected to their laptop, theyll read all your information (username, password.. bla..bla..bla..). More complex to set up than wired network. Affected by surrounding. E.g walls (blocking), atomise oven (interference), far distance (attenuation)
