WLAN - Essay ExampleIt is also known as Wireless-N.(Rathbone, 2012) It is the in style(p) 802.11 amendment that offers the high speed information transfer rate with improved signal ranges than the previous amendments. As a matter of fact, the verified speeds for 802.11n devices are 7 times faster than 802.11g while communicating at ccc Mbps or more in real world scenario. Evidences proved it as the first Wi-Fi 802.11 amendment that has challenged the 100 Mbps outfit Ethernet architectures.802.11n supporting devices are designed for better performance at long distances, which means that if a movable device is 300 feet away from the Wi-Fi access point it will still retain its actual data rate. Distinguishing it from older versions of 802.11, where data rate and communication with the access points tend to be weakened when a portable device is that far.As we know that 802.11n has been standardized and groups in wireless industry such as the Wi-Fi fusion have been forcing for backwa rd compatibility among 802.11n and its previous version supporting devices has reduced the risk of buying devices that may non communicate with each other or with older hardware.Studies showed that cross technology interference put forward be main issue for almost all the 802.11 amendments. A research based study in 2010 by giants like Miercom, BandSpeed and Farpoint Group showed that these huge interferers like microwave and cordless phones can be responsible for completed connectivity loss for 802.11n connectivity. The reason behind this is, some of these devices transmit frequency in band that is as liberal as 802.11, while each one of these give out power that is equivalent or sometimes higher than 802.11 device. As we know that 802.11n inherent the MIMO technology. (Madisetti, 2010, p. 27-28) One solution can make it possible if we use a 33 802.11n transmitter. It will help in a way that all the interferences can disturb one stream while still two parallel streams are pre sent for its receiver.The suggested
