Wi Fi Coverage Area And Signal Strenth Improvement Using Cantenna

Should Wi-Fi technology in the 21st century be kept from the wild? In The Atlantic article “Wifi in the Woods” by Jason Mark, the internet is difficult for people to get away from. Mark discusses that a group of people travelling to the tundra, including DJ Spooky (a record producer), adapted to their environment, when they encountered a loss of internet signal. He also explained that companies are laying out plans to add internet to wild country. Furthermore, he discusses the pros like checking weather information and global connectivity, and the cons like no escaping from government oppressors and losing the calmness of the wood. Wifi technology is of more positive development in rustic

Wireless network infrastructure has become just another connection method for corporate and home users alike. This rapid acceptance can be attributed from:

This is a direct extension of the 802.11b that extends the maximum data rate to 54Mbps, making it possible to serve up to five times as many users. Our Wi-Fi network is based on the IEEE 802.11 b/g standards, which is the most commonly used standard. We have added Wi-Fi access points in our network to give easier access to corporate data and services. Most of the devices in this network, for example the personal computers, smartphones, digital cameras, tablets and digital audio players connected using the Wi-Fi technology. The hotspot will be in the range of 20 meters (66 feet) indoors and a greater range outside.

Wi-Fi Protected Access 2, the follow on security method to WPA for wireless networks that provides stronger data protection and network access control. It provides enterprise and consumer Wi-Fi users with a high level of assurance that only authorized users can access their wireless networks. Based on the IEEE 802.11i standard, WPA2 provides government grade security by implementing the National Institute of Standards and Technology (NIST) FIPS 140-2 compliant AES encryption algorithm and 802.1x-based authentication.

To solve these problems a company can implement Wi-Fi on their network. This can reduce the price of implementing additional cable in the network.

This will provide the company with the chance to more efficiently manage its activities (Mangiaracina et al, 2011). At present, the company does not have any key plans in place to provide it with help with managing its applications. It is however critical for the company’s management to ensure that it clearly understands the importance of putting in places a wireless technology. This is due to the fact that the company will have a better chance to track its inventory while at the same time ensure that it is able to remotely control all of its 10 new stores (Rekik et al, 2009).

Municipal Wi-Fi or Municipal wireless network is a step towards making Internet services available to everyone by wireless technology. A geographical area under a municipality is provided with a wireless broadband service in many cities in US. Currently this idea is getting spread around the world. The structure of the wireless network is a mesh network with more than hundreds of routers are installed on the outdoors of the buildings. The network is operated by a wireless ISP. In this report we will discuss about implementation of municipal WiFi in different countries and the status of those implementation.

Known to many as Wi-Fi, its actual name is “Wireless Fidelity.” Wi-Fi is considered to be what correlates to wireless networking technology of which allows computers amongst other devices to communicate over a wireless signal. The designation 802.11

In 1991 wifi was invented, and as the years go on wifi has been developing and changing in the most incredible ways. Wifi has also changed on how we communicate with people, and how we shop for items. As changes come, trouble also comes with it. In recent years, parents have been blaming wifi for the recent problems their children have been facing. The research and studies that have been conducted shows that an increase in wifi access and coverage does not pose a danger to students in

It’s very important to determine the device and application requirements based on bandwidth, protocols and frequency. In wireless network, bandwidth, protocols and sometime environmental conditions affect the speed of the channel so we need to calculate the aggregate throughputs before designing the network. Today, users carry Wi-Fi devices such as notebooks, laptops, tablets and Smartphone’s so total throughput must be calculated by estimating number of connections rather than the number of the seats. Some common wireless networking standards such as 802.11a/b/g/n invented in the IEEE association must be supported by wireless network. For better performance and for faster devices (802.11n devices), dual-ratio access points should be deployed. Table1 [3] illustrate the different IEEE standards and throughput.

Wireless networking hardware requires the use of underlying technology that deals with radio frequencies as well as data transmission. The most widely used standard is 802.11 produced by the Institute of Electrical and Electronic Engineers (IEEE). This is a standard defining all aspects of Radio Frequency Wireless networking

There are lots of challenges occurs for reliable wireless communication which occurs due to physical limitations of the wireless medium. There has been massive growth occurs in wireless communication which is due to the techniques that improves spectral efficiency and mitigate various channel impairments such as fading and interference. Moreover there is always demand for high speed wireless internet and technologies which are capable of providing higher capacities and link reliabilities. Multiple-input-multiple-output (MIMO) is based on communication system which is able to fulfil these objectives. MIMO is an expansion of smart antennas systems. There were traditional smart antennas which occupy multiple antennas at receiver, whereas In MIMO system multiple antennas are engaged at both sides at transmitter as well as receiver side. The multiple antennas at the transmitter and the receiver side provide a major advantage over traditional smart antenna systems—in terms of capacity and diversity advantage. The multipath propagation by MIMO system is a remarkably advantage over other antennas system. Moreover it is able to provide independent fading channels between every pair of transmitter and receiver antennas.

WiMAX (Worldwide Interoperability for Microwave Access) is present as a solution to the limitations of access at Wi-Fi planned for adoption in the space. The use of OFDM technology is able to provide data service to 70 Mbps in a radius of 50 km. Radius to make WiMAX broadband telecommunications network as technology replaces fixedline. Compared to the fixedline network WiMAX installation fees are much cheaper.
