1. Wireless LAN: Wireless LAN (WLAN) stands for wireless local area network also referred as LAWN. LAWN stands for local area wireless network, is one in which user can connect to a local area network through a wireless connection using radio signals. This LAN provides wireless communication over a short distance area using radio or infrared signals. This can be build using any different wireless network protocols, most commonly either Wi-Fi or Bluetooth. The pros and cons of wireless LAN is as following. 1.1. Pros • A large number of devices are supported. • It's easy to set up a WLAN, especially when compared to laying cables for wired networks. • Accessing a WLAN is easier than a wired LAN since cable length isn't a factor. • WLANs are common…show more content…
Performance It support the maximum data rate of 11MHz which is comparable to traditional Ethernet network which supports 10MHz data rate connection. 2.2.3. Issues with 802.11b Due to transmission in the unregulated 2.4GHz frequency it is found that it make interference with the other wireless household equipment’s e.g. cordless phone, microwave oven, garage door openers, and baby monitors. 2.2.4. 802.11b and backward compatibly It has a backward compatibility feature even it is being use in new wireless network technology. Its main reason is that each newer generation of the main Wi-Fi protocols standards has maintained backward compatibility with all old generations. The feature of backward compatibility prove the success of Wi-Fi technology, as consumers gradually replace their old devices with minimal interpretation by adding newer equipment in their networks. 2.3. 802.11g It is an IEEE Wi-Fi wireless network technology, supports wireless local area network communication among different devices like other Wi-Fi technologies. It was built in June 2003, replace the older standard which is 802.11b. 2.3.1. Working of…show more content…
These routers provides most high speed internet connections with 54MHz speed for basic online gaming and videos streaming usage. They are being sale on less expensive rates on both retail and secondhand sales points. The only disadvantage of G is that it reaches its performance limits so quickly when multiple devices came in connection with it and become active, and it is true for any network when it is being consumed by many devices. The additional advantage of G routers is that they are designed for fixed installations at home. 802.11g wireless technology get popularity with its travel routers among the business professional and people who want to share a common Ethernet connection among various wireless devices. But these travel routers become in common in use as hotels and public networks are shifts towards wireless hotspots from Ethernet connections. 2.4. 802.11n This become in market in 2009, it is IEEE industry standard for wireless local area network communication. The purpose of the design of 802.11n is to replace the older version of wireless LAN technology standards which are 802.11a, 802.11b and 802.11g. 2.4.1. Working wireless technologies in
