802. 11a Standard Essay

There are 9 IEEE 802.11 services in total which can be classified into to categories:

During this presentation we learned of the network types that Whitewater uses and how they differ. For example they have three different networks which separate devices that are allowed to access the network. Their network gives each device a certificate that is good for 2 years. They also recently implemented a check in for devices accessing the network so that they can verify whether or not the user has an anti-virus installed.

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.

A: The 802.1 standards provide LAN/MAN management. The 802.1 standards where created by the close of the 1970’s.

Outline a wireless network and technology that you use regularly. The WLANs which are derived from the IEEE 802.11 standards, and marketed under the Wi-Fi trademark name. The WLANs security is neither forthright/candid nor simple, and it is continuously varying. Even though, as WLAN increase client output, they also expose the networks to a new group of potential hackers. With the present inherent security weakness of the 802.11 standard, all companies, small, medium or large, need to find out their security conditions derived from the applications using the WLAN. The standards also provide requirements for high-speed networks that support most modern-day applications. What sorts of security issues do

11. Today, most wireless local area networks use the _____ standard, which can transmit up to 54 Mbps and has a range of about 300 feet.

Today’s current standard of 802.11 is 802.11ac. When comparing newer routers for home use, you will run across routers labeled AC1200, AC1750, AC3200, and so on. The “AC” refers to the wireless standard, while the number following it refers to the speed. The current range of 802.11ac routers can provide speeds up to 1300Mbps on the 5 GHz band, and up to 450 Mbps on 2.4 GHz band. The base level for 802.11ac is more than twice the speed offered from the previous standard, 802.11n. Most routers available in stores today offer 802.11n or 802.11ac, older standards such the “a,” “b,” and, “g” are out of

WiMAX can transmit speeds up to 50km at 280mbps, and provides options for use in point to point and multipoint configurations.

WAP came in shortly behind WEP with secure networking communication in mind. It’s a later discovered that WEP doesn’t protect much at all and was then replaced with WPA/WPA2. WPA/WPA2 is the most widely used today. In fact, the only time WEP should be used is when there needs to be communication with old devices that don’t support encryption. WEP, or Wired Equivalent Privacy, is not hard encryption to crack. WAP, or Wireless Application Protocol, uses a smaller revision of HTML called Wireless Markup Language (WML), and is used is wireless devices. WPA/WPA2 is now known as the most secure communication over the internet today. WTLS, Wireless Transport Layer Security, provides authentication, encryption, and data integrity for wireless devices (Dulaney,

It was designed to replace 802.11a, 802.11b and 802.11g. It has the fastest transfer rate of (600Mbps) and the longest signal range compared to its predecessors. It operates in both 2.4GHz and 5GHz range.

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.

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.

“IEEE 802 subdivides the data link layer into sublayers, namely the logical link control (LLC) and media access control (MAC) layers, which provide protocol multiplexing and a multi-access mechanism, respectively. IEEE 802 is comprised of standards with separate working groups that regulate different communication networks, including IEEE 802.1, 802.3, 802.11 and 802.15.” (Technopedia, 2014).

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
