This shows us two different sides of power. ————————————————- Power is often used as a source of violence in the text, â€Å"Lord of the Flies†. The idea of power is expressed differently; imagine a world where there were no rules, no laws, and no government to oversee the running of the country. In â€Å"Lord of the Flies†, to gain power was competitive which meant strife. The desire for power breaks down the boundaries set by rules and order.

Comment on the film techniques employed by the composer of this text. How do they contribute to the meaning of Power in the text? Brook’s film opens with a very creepy montage consisting of pictures of a British boarding school intercut with planes flying over London with a haunting school chorus playing in the background. Brook’s use of grainy black-and-white photography, plus the lack of any comprehensive musical score (remember Tom Hanks’ â€Å"Castaway†? ), accentuates the bleakness of its surroundings and feelings of isolation. The movie can hardly be expected to capture fully every single intention of this highly complex novel (most don’t), but it does respect Golding’s words and captures the very essence of what he wanted to say. For that alone it should be applauded. Brook is able to compose beautiful sad visuals. ***SPOILERS*** These include the kinetic editing during the hunt for Ralph, Simon’s dead body floating in the water arranged by the sad school chorus (depressing moment), Piggy’s tragic demise that puts the 1990s remake laughable mirrored scene to shame, and the very scary feast that occurs at night followed by the dance. That scene, consisting of quick images, scary close-ups on the savages painted faces ————————————————- It is disturbing, haunting, and visually wonderful. ————————————————- In Peter Brook’s film, â€Å"Lord of the Flies†, released in 1963 was a black and white film. Although it was black and white film, it’s underrated and it’s still a classic, this is preferably better than the new remakes of this film. Some scenes are considered as disturbing and haunting but visually wonderful. Brook uses a very creepy montage in the opening scene showing pictures of a British boarding school with planes flying over London and a haunting school chorus playing in the background. Brooke uses grainy black and white photography and emphasizes the bleakness of its surroundings to create a feeling of isolation, which relates to a feeling of savagery vs. civilization. With Brook being able to compose beautiful sad visuals, he is able create the scene of Piggy’s tragedy with quick images, scary closer-up shots on the savages painted faces of the hunters (Jack’s tribe). This scene shows influence of fear, the invariable corruption of power/ losing control and a sense of savagery vs. civilization. 4. How does this text relate to your prescribed text i. e. George Orwell’s Animal Farm? Link each text by exploring three common aspects of Power. * well the power in the  lord of the flies  is jack’s rise to control and leadership. he leads an army of corrupt boys who carry out his evil orders (set the island on fire, orders to kill ralph, etc. ) * in animal farm, napoleon takes the power from snowball and forms a dictatorship. e also has minions such as the dogs who carry out his tasks and corrupt orders. ————————————————- Ralph represents a democracy while Jack represents a totalitarian form of leadership. lead the boys into savagery   ———————————â €”————- Want power, Greed or selfishness bring the destruction of the societies, ————————————————- In Animal Farm the animals hated the humans and were scared that they might take back the farm. Napoleon uses it as an excuse to keep the animals working. In Lord for the Flies the littluns are afraid of the â€Å"beast†. When Jack, Ralph, and Roger went and saw the beast, which is a parachute and a man, the biguns also got scared. ————————————————- The pigs took control and the other animals were in worst condition than they were in when the humans were in control. The boys ended up disagreeing and killing each other ————————————————- â€Å"Lord of the flies† is very similar to the novel Animal Farm by George Orwell. They relate with a common theme of power. However, both are from different context but written for the same reason, â€Å"Lord of the Flies† is a story of humanity from a navy officer, which served in WWII, while Animal Farm is based on the Russian Revolution. The plot, the characters and the symbols are very similar. Three common aspects of power in these texts is the want of power, the control of power, the reality of betrayal. The antagonist in each text, both want power and used a belief to manipulate the others. In Animal Farm Napoleon tells the other animals to hate the humans and they were scared that the humans might take the farm back. Whereas in â€Å"Lord of the flies†, Jack tells the littleuns that there is a ‘beast’ on the island and if they worked for him, he would provide them with protection. Another aspect is the control of power, in Animal Farm Napoleon takes the power from Snowball and forms a dictatorship. He uses the other animals to work for him, such as the dogs that carry out his tasks and corrupt orders. In â€Å"Lord of the Flies†, Jack rises to control and leadership. He carries out an army of corrupt boys to carry out his evil orders, similar to Animal Farm. Both Napoleon and Jack represent totalitarian forms of leadership. And lastly, the reality of betrayal was common in both texts. In Animal Farm the pigs had started to become like humans, wearing clothes, sleeping in beds, drinking alcohol and playing cards with humans in the farm house. The other animals saw them through a window and couldn’t tell whether they were pigs anymore or humans. In â€Å"Lord of the Flies†, Jack starts his own tribe with his hunters, the littleuns, he went to steal Piggy’s glasses, but Ralph went to look for it, then suddenly Jack stabs Ralph in the back, but luckily Ralph survived.

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.

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 uses 5 GHz in an AP-to-AP interlink. Abstract: This paper presents a description of the existing wireless technology Wi-Fi and WiMAX, and try to compare Wi-Fi (IEEE 802. 11) and WiMAX (IEEE 802. 16), with respect to which technology provides a better solution to build a wireless access infrastructure.

INTRODUCTION With the help of many expert communication engineers IEEE has developed various wireless standards in a hierarchical fashion. Some of the deployed wireless standards are: 802. 15 (Bluetooth), 802. 11 (Wi-Fi), and 802. 16 (WiMAX) promoted by WiMAX forum. Recently a new standard, 802. 20 for WANs has been proposed, which is currently under development. Each of these IEEE standards has been deployed to fulfill certain criteria and they complement each other. IEEE 802. 11 also known as Wi-Fi standards has had a lot of commercial success, for this reason now the focus of wireless networking shifting to the wide area market. Wi-Fi has been optimized to address the requirements for home or office connectivity but the wide area market is still open to grabs. So to grab the market the low cost wireless which appears is WiMAX, short for Worldwide Interoperability for Microwave Access, is positioned as solution for outdoor and long-range last-mile solutions. Many service providers had adopted this technology as a quick and cheap option to provide connectivity between access points or base stations and their backbone network. The main goal of WiMAX is to provide cheap and fast connectivity of both voice and data communication to remote and difficult terrain locations. With the increasing market demand for WiMAX, it is now regularly compared with Wi-Fi. While both technologies have some identical technical characteristics, however they are approaching the wireless space from completely different perspectives. The purpose of this paper is to provide a technical and market comparison of Wi-Fi and WiMAX technologies in Figure 1: Wi-Fi Network ? The 802. 11b and 802. 11g standards use 2. 4 GHz. Different frequency bands are used by the 802. 11a, 802. 11b and 802. 11g standards; Different devices using these different frequency bands do not interfere with one another. However, portable devices using different bands cannot communicate with each other, for example an 802. 11a radio cannot communicate with an 802. 11b radio. The most commonly used standard in the Wireless LAN are the 802. 11b and 802. 1g standards because of their interoperability and the greater range option that they achieve in the 2. 4-GHz band. Each standard also use different types of radio-modulation technology, which is as follows [2]: †¢ The 802. 11b standard uses direct-sequence spread spectrum (DSSS) and supports bandwidth speeds up to 11 Mbps. †¢ The 802. 11a and 802. 11g standards use orthogonal frequency di vision multiplexing (OFDM) and support speeds up to 54 Mbps. Because OFDM is more suitable to outdoor environments and interference, that’s why it is commonly used for Wireless LAN infrastructure. 2. 2 WiMAX: IEEE standard 802. 6, also known as WiMAX, is a technology for last-mile wireless broadband as an alternative to cable and DSL and where the cost is high. It’s intended to deliver high speed data communication, and it also has the ability to maintain dedicated links and VoIP services at a reliable and high quality speed. Figure 2: WiMAX Network Not only it supports â€Å"last mile† broadband connectivity to individual home or business locations but also its data rates are comparable with cable and Digital Subscriber Line (DSL) rates. Many telephone companies also desire that WiMAX will be a replacement for their aging legacy wired networks. In fact, it is looked as the wireless replacement for a wired broadband connection. WiMAX has the ability to allow a subscriber to connect to a wireless Internet service provider even when they roam outside their offices or homes. With the large coverage range and high data transmission rate WiMAX’s attributes open the door of the technology to a variety of applications. WiMAX can be used as a backbone for IEEE 802. 11 hotspots for connecting to the global world, as well as a subscriber can connect WiMAX enabled mobile devices such as laptops PDA or cell phones directly to WiMAX base stations without using IEEE 802. 11. Currently many service providers, providing a DSL or T1/E1 service for a business customer to a relatively remote location or outer suburbs can take several months and the cost associated with it is very high. With the help of WiMAX, a service provider can provide that service in a short time and in a very cost effective way [3]. One of the main application of the WiMAX is that it can be used in disaster recovery scenes where the wired networks have broken down. In recent many disasters, WiMAX networks were installed to help in recovery missions [4]. Similarly, WiMAX also be used as a backup links where the traditional wired links breaks. WiMAX mainly operates in two frequency ranges. One is high frequency, which is between 11 – 66 GHz and another one is low frequency, which is sub 11 GHz [3]. Line-of-sight is very essential when operating in the high frequency range. This frequency range allows this wider channel, resulting in very high capacity links. For the low frequency range (sub 11 GHz) non line-of-sight is essential. WiMAX, with a theoretical data rate of 70 Mb/s in 20 MHz channels (2-11GHz spectrum) , allows a few hundreds of DSL connections but it operates up to 124Mbps in the 28MHz channel (in 10-66GHz), [5]. The maximum range WiMAX, covered is about 50 km [5]. But in practice this range may be decrease to 20 km and even 8 km when there are obstacles [5]. 3. 1 Efficiency Efficiency of wireless technology is measured in terms of bandwidth and latency. Efficiency is a major issue to determine what type of applications can be run on a network. A lessbandwidth network only feasibly for small application and normally support simple data application for example transferring text files. A higher bandwidth network normally used for big application such as audio and video and many more powerful applications. Another major issue in case of real-time applications like voice is latency which is very much crucial issue. The maximum range of latency should not be more than 20 ms, anything higher than that be warring for establishing echo free wireless network. 3. 2 Maximum Range Maximum range is calculated from the obtained distance between the two base stations, and like cell phone another major issue must consider here that the technology must have the capability to support hand-off between base stations without loosing connection from the global world. Maximum coverage range is a major issue, the reason behind that, it determines how long a contiguous wireless area can be? Also, maximum coverage range of wireless technologys is very much crucial according to cost, since operators can reduce their initial capital expenditures if they can give the coverage of the same area with smaller number of base stations. 3. 3 Dependability Dependability is defined as how much a wireless technology is dependable to the end user. Whether end user think that is it reliable to use or not? Dependability measure with few important metrics like average number of packet loss, average number of disconnects of calls, and whether the wireless technology is hampered by environmental issues such as line of sight, weather, etc. Dependability is very crucial because some applications may require a reliable connection. If a connection is not dependable, in that case packets may loss and that affect the network for that reason the speed of the network will decrease. This would have certainly impact on the performance of any applications, hence decreasing the applications that will use on the wireless network. . 4 Security Today’s internet is open for all. And user exchange many personal data in internet. So normally end user wants security. Security is obtained from the level of encryption of the data and the authentication of the device is provided by each technology. For many applications such as exchanging bank information require a secure connection to transmit confiden tial information. Mainly the end user will not want to expose themselves and they also want that the secret information not being viewed by unauthorized individuals. That’s why security is needed in wireless connection. III. KEY CHARACTERISTICS OF WIRELESS TECHNOLOGY This paper focuses on the hypothesis that which wireless technology, WiMAX or Wi-Fi provides a better solution in the wireless access infrastructure. Whether one wireless technology provides a better solution than any other or whether a combination of technologies is needed to create the desired infrastructure. The key characteristics for which the most powerful next generation wireless technology (WiMAX and Wi-Fi) is evaluated in this research paper are: efficiency, maximum range, dependability, security, market issue and mobility. These six key characteristics are the standard issue which will be used to compare these two wireless technologies. 3. 5 Mobility Mobility is one of the major issues in case of building wireless access infrastructure. It is the speed of the mobile access point at which the technology can remain connected to the global world without losing packets or service interruption. Naturally, a wireless infrastructure environment needs to be mobile to provide connection to the end user at any place they visit. The network must sustain connection at vehicular speeds. 3. Market comparison The last characteristics to consider when evaluating wireless technology is a market. Actually the popularity of any technology is determined by the market. Mainly markets certify a technology whether it is accepted by end user or not. So based upon the market we can decide which technology is most attractive to the wireless world IV. Wi-Fi VERSUS WiMAX 4. 1 Radio Technology: WiMAX differs from Wi-Fi in the radi o technology sector. The IEEE 802. 11 WLAN standards describe four radio link interfaces that operate mainly in unlicensed radio band having range from 2. G to 5 GHz [9]. The WiMAX 802. 16a standard released in January 2003 operates between 2 GHz and 11 GHz [9]. The lower frequency bands support Non-line-of-sight (NLOS) for that reason customer unit need not be aligned with base station. Wi-Fi mainly operates in unlicensed frequency bands, but WiMAX can operate in both licensed and unlicensed spectrum. Within IEEE 802. 16a’s 2-11 GHz range, four bands are most attractive [9]: * Licensed 2. 5-GHz MMDS * Licensed 3. 5-GHz Band: * Unlicensed 3. 5-GHz Band * Unlicensed 5 GHz U-NII Band. 4. 1. 1 Radio transmission Modulation techniques: The IEEE 802. 1b radio link uses a technique direct sequence spread spectrum that is called complementary coded keying (CCK) for radio transmission [9]. Bit stream is mainly processed by a special coding and modulated with the technique called Quad rature Phase Shift Keying (QPSK). The 802. 11a and 802. 11g uses the radio link technology 64-channel orthogonal frequency division multiplexing (OFDM) [9]. Here the bit streams is encoded on the 64 sub carriers using Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), or one of two levels of Quadrature Amplitude Modulation (16-, or 64- QAM) [9]. The IEEE 802. 16a specifies three techniques for radio link [9]: * SC-A: Single Carrier Channel. * OFDM: 256-Sub-Carrier Orthogonal Frequency Division Multiplexing. * OFDM-A: 2,048-Sub-Carrier Division Multiplexing. Orthogonal Frequency 4. 2 Efficiency: Maximum channel bandwidth for Wi-Fi is 25 MHz for IEEE 802. 11b and 20 MHz for either IEEE 802. 11a or g networks [9]. The maximum bit rates it’s providing is 54 Mbps. Wi-Fi has latency in the range of 50 ms hence little bit higher latency. In WiMAX, the channel bandwidths are in the range of 1. 25 MHz to 20 MHz [9]. Basically there has been lots of confusion regarding the actual bit rate of a WiMAX channel. But many articles give a range in of 70 M or 100 Mbps, basically exact transmission rate depends on the assigned bandwidth of the channel. WiMAX have latency in between the range of 25 to 40 ms, quite considerable range. Now have a close look at the Bandwidth efficiency of the both technologies. Basically it is measured by the number of bits per second that can be carried on one cycle of radio bandwidth (i. e. bps/Hertz). Lets have a data rates supported on its 25 MHz channel (1 M to 11 Mbps), 802. 1b have bandwidth efficiency in between 0. 04 to 0. 44 bps/Hertz [9]. In 802. 11 a or g on its 20 MHz have a transmission rate from 6 M to 54 Mbps yields a bandwidth efficiency in between . 24 to 2. 7 bps/Hertz [9]. In case of WiMAX, for 70-Mbps transmission rate on a 14-MHz radio channel yields bandwidth efficiency up to 5- bits/Hertz [9]. Basically the bandwidth efficiency decreases when the tran smission range increases. 4. 3 Maximum Coverage Range: OFDM modulation has a high spectral effectiveness that why WiMAX ranges 8 km (NLOS) to 50 km (LOS) [5]. It handles many users who are widely spread out. Mesh topologies and smart antenna techniques can be used to improve the coverage. The OFDM designed for the BWA and main goal is to provide long range transmission. 802. 16 is designed for high power OFDM used to maximize coverage up to tens of kilometers [5]. In contrast, IEEE 802. 11 standard have a basic CDMA and OFDM approach with a quite different vision. It required very low power consumption of energy that whys it can support very limited range of coverage. It is mainly designed for indoor use. Optimize range of this technology is around 100 meters [5]. 4. 4 Security: One of the major issues that differentiate from Wi-Fi to WiMAX is security. It’s a major issue because it protects transmissions from eavesdropping. But security has been one of the major lacking in Wi-Fi, encryption is optional here. But better encryption techniques are now available some of the different techniques used are [9]: †¢ Wired Equivalent Privacy (WEP): An RC4-based 40- or 104bit encryption technique. †¢ Wi-Fi Protected Access (WPA): A new standard from the WiFi Alliance that uses the 40- or 104-bit WEP key. †¢ IEEE 802. 1i/WPA2: It is a IEEE standard which will be based on a more robust encryption technique called the Advanced Encryption Standard. WiMAX is designed for public network so security is very much crucial here. So all the data that is transmitted in WiMAX network is virtually encrypted. The main encryption technique that is used here is 168-bit Digital Encryption S tandard (3DES), the same encryption also used on most secure tunnel VPNs. There are also plan to include the Advanced Encryption Standard (AES) in WiMAX to maximize the security. 4. 5 Mobility Management Mobility management is supported by WiMAX. The latest IEEE 802. 16e is made for Mobile WiMAX. This standard supports mobile capability with the support of hand-offs capability, mainly for users when they moved between cells. Its support data rates up to 500 kbps, equivalent to the highest speed cellular offerings (e. g. Verizon Wireless’ 1xEV-DO service) [9]. Currently mobility management is not supported by Wi-Fi. But recently IEEE has begun to development of a roaming standard for Wi-Fi. However, WLAN switch vendors like Cisco, Aruba, and Airespace have developed their own proprietary hand-off protocols [9]. 4. Market Comparison Up to this point we have focused on technical issues here we consider, some market issues of these two products. Some market oriented works have been established for Wi-Fi service. The two examples are Wireless ISPs and Wi-Fi mesh networks. 4. 6. 1 Wireless ISPs (WISPs) The idea behind Wireless ISP (WISP) is to provide an Internet access service using WLAN technology and a shared Internet con nection in a public location designated a hot spot. TMobile and Wayport are currently providing this type of service [9]. But it have two problems, one is technical and another one is business oriented. From a technical viewpoint, to access the internet you have to be within the hot spot. From a business viewpoint, users have to pay monthly basis for the internet then the users have to be in the hot spot always to access the internet which is not a feasible solution. So markets of wireless ISP are in a threat now. 4. 6. 2 Wi-Fi Mesh Network Wi-Fi mesh networks are mainly used to support public safety applications and also to provide Internet access to end users. However, mesh technologies are not within the range of the Wi-Fi standards. 4. 6. 3 WiMAX Market The market goals of WiMAX not clear at the moment. But in a sense we can say that the major goal will be broadband wireless access or Wireless DSL. But it will succeed only if it provides lower cost service and also provide some extra features which the other broadband like DSL do not provide. WiMAX compatible chipsets first appeared in late-2004 by the Intel and consumer devices costing $100 or less [9]. But in case of WiMAX, before investing in this field, they have to think and analyze that whether they have enough demand in the market or not. 4. 7 Quality of Service (QoS) Wi-Fi is based on a contention based MAC (CSMA/CA). Hence no guaranteed QoS is provided mainly it can support best offer services. The Standard does not permit for different service level for each user. There is a plan to incorporate QoS in the 802. 11-e standard. In this standard two operating modes will be included to improve service for voice one is Wi-Fi Multimedia Extensions (WME) and another one is Wi-Fi Scheduled Multimedia (WSM) QoS in IEEE 802. 16 is based on a request/grant protocol. Its support multiple QoS which is build in MAC. It is designed to supports different service levels such as ,T1/E1 for business and best effort to consumer. This protocol support delay sensitive services such as voice and video. The dynamic TDMA based technique allows the suitable support for multicast and broadcast. In the below the key difference between Wi-Fi and WiMAX is described Table:1 Comparison between IEEE 802. 11 and IEEE 802. 16 802. 11 (Wi-Fi) Primary Application Range Coverage and Wireless LAN 802. 16 (WiMAX) Wireless MAN mainly designed for broadband wireless Designed for outdoor NLOS performance Optimized for 50 km Mesh topology is supported MAC designed to support thousands of users Licensed and Unlicensed Band 2 GHz to 11 GHz Adjustable range from 1. 25 to 20 MHz
