Advantage And Disadvantage Of Wifi

1.0 Background

In modern day, information can be available at the tips of our finger, through the application of smart phone, tablet, laptop, and desktop. Having the internet facility, we can access vast body of knowledge at anywhere anytime. Internet enabled the linkage of a computer to any other computer anywhere in the world through the standard Internet protocol suite (TCP/IP).

Wireless technology enable human interconnectivity from almost anywhere; at home, at work, libraries, schools, airports, hotels and restaurants. Wireless networking is known as Wi-Fi (Wireless Fidelity) or 802.11 networking as it applies the IEEE 802.11 technologies. The advantage of Wi-Fi is that it is compatible with most operating system, game device and advanced

Wi-Fi is one of the the preferred modes of internet connection all over the world since it is mobile. While in the same time connecting us to the sea of information, it allows us to connect and search the vast source of information through our communication devices. To access this connection, we must have a wireless adapter on the computer or the specific communication devices. Wi-Fi provides wireless connectivity by emitting frequencies between 2.4GHz to 5GHz based on the amount of data on the network. To start a Wireless connection, it is important that the wireless router is plugged into the internet connection and that all the required settings are properly installed.

1.1 Problem statement

Due to increased usage, the size of data transmission becomes bigger and bigger day by day. Efficiency of our data communication depend on the speed of the internet, thus better performance Wi-Fi is required so that we can get the jobs done faster. Unisel has provided Wi-Fi connectivity to all the students so that student can use it for their study purpose. University has thousands of students living in the hostels, without a good Wi-Fi performance in these area will certainly cause serious connectivity problem to

A five story building, with each floor having twenty four occupants and most of the student possess two smart phones with a laptop/desktop. This means just a single five storey building will have approximately three hundred sixty devices that are always connected to the Wi-Fi system. The environment is a space of about four thousand square feet land, having interference or ‘overlapping’ of so many WiFi channels. This situation certainly induces floor noise, which result in low speed connectivity.

Thus the current scenario demands the study on the performance of WiFi in Unisel student hostel, in order to identify the root cause of the problems which cause depletion of WiFi performance.

1.2 Objective

• Analyze the factors which cause Wi-Fi performance depletion at student hostel using Ekahau Heat Mapper.

• Calculate link budget of Wi-Fi from collected data to determine the efficiency of current Wi-Fi at student hostel.

• Propose better alternative options for improving the performance of the Wi-Fi in student hostel area if the analyzed data shown any ineffective link of budget outcome.

1.3 Scope of study

Analyze the student personal broadband channel and university routers channel in Unisel hostel. This analysis will be conducted at male student hostel, block B, range from B1 to B4, at all
