Nt1310 Unit 2 Case Study
1. The first standard was created in 1997 by the Institutue of Electrical and Electronics Engineers (IEEE). They called it 802.11 which only supported a maximum network bandwidth of 2 Mbps- too slow for most applications.
2. After doing some reaserach I found that 802.11b and 802.11g equipment suffer interference from microwave ovens, cordless phones, and other appliances using the same 2.4 GHz ISM band.
3. The 802.11n standard is the fastest. It is 4–5 times faster than 802.11a or 802.11g, and perhaps 20 times faster than 802.11b.
4. The fastest standard is not always the best because other factors on wireless network and internet affect can affect the performance.
5. Generally a cost premium is placed upon wireless acccess points with faster

    * While consumer PC products have just started to migrate to much higher bandwidth 802.11n, now the work on next generation WLAN standard definition is already in progress. Named as 802.11ac, it is expect to boost the network bandwidth up to 1Gbps, on par with what can be achieved by wired networking in today’s PC world.…

    Hills covers some of the developments in wireless local area network (LAN) technology since he and his team built the first large-scaled wireless LAN at Carnegie Mellon University. One development is the adoption of the IEEE 802.11 standard by wireless LAN. This standard is largely known as Wi-Fi. Hills then covers the workings of Wi-Fi networks.…

    All wireless technology is backward compatible with previous versions of this technology. This is enforced by IEEE (Institute of Electrical and Electronics Engineers) because they control the wireless networking standards. IEEE insures that advancing technology within the spectrum of wireless networking will not outdate previous versions and therefore render them useless. An example of this that we can all associate with would be cellular data technology. “There used to be 1G now…

    With Legacy 802.11 protocols, speeds maxed out at around 2 Mbits/sec and indoor range was only about 20 meters. In 1999, the 802.11 protocol got a couple of amendments in the form of 802.11a and 802.11b. Both offered higher speeds and slightly greater range, but there were many differences between the two standards in how they achieved those two things. 802.11b uses an offshoot of the same modulation technique as the older Legacy protocol, known as complementary code keying (CCK) (based on direct-sequence spread spectrum used in Legacy). Both protocols also use CSMA/CA for multiple access, which is the reason both Legacy and 802.11b protocols were much slower than any of the other versions we’ve seen – CSMA/CA carries a lot of overhead meaning much wasted bandwidth. With 802.11a, we see much faster speeds (54Mbits/sec versus 11Mbits/sec with 802.11b) thanks mostly to orthogonal frequency-division multiplexing (OFDM) and its use of the 5MHz bandwidth spectrum which is much less crowded than the 2.4GHz spectrum used by 802.11a and Legacy protocols. Despite these distinct advantages, 802.11a lagged behind 802.11b due to slow availability of the 5GHz hardware to manufacturers and the fact that first wave of hardware put…

    order to highlight that which technology will be better to build a wireless access infrastructure. The first part of the paper examines the both of these wireless technology in order to understand both technologies and their underlying concepts. Then, I have discussed some key characteristics to compare the both of these technologies. The last part concludes and presents a conclusion of which will be the best technology to build a wireless access infrastructure. II. OVERVIEW OF THE CANDIDATE TECHNOLOGIES. 2.1 Wi-Fi The dream to network PCs and other devices without the cost and complexity of cable infrastructures has driven the rapid growth in the wireless market over the last few years.Wi-Fi is one of the wireless technology which appeared early in the wireless market. Wi-Fi is based on the IEEE 802.11 wireless local area network (WLAN) specification. Actually it was designed to be used indoors at close range for example home user and office environment. The main goal of Wi-Fi technology is to provide service for mobile computing device like laptop. But recently it is used for more services for example consumer device such as televisions, digital cameras, and DVD players. A user with a mobile computing device such as a laptop, cell phone, or PDA which is Wi-Fi enabled can connect to the global Internet when it is within in range of an access point. The region which is covered by one or more access points is called a hotspot. Hotspots can range from a single room to thousand of square feet’s of overlapping hotspots. Wi-Fi can also be used to create a mesh network. Wi-Fi also allows connectivity in peer-to-peer (wireless ad-hoc network) mode, which enables devices to connect directly with each other [1]. This connectivity mode is useful in consumer electronics and gaming applications [1]. Wi-Fi products can use different radio frequencies [2]: • The 802.11a standard…
