Wireless technology has come a long way from the 1980’s to 2014. Years ago before DSL, T1, and cable modems existed, the majority of people were using Dial-up. Today, with technology becoming more advanced and forever changing, there are more ways to stay connected whether at home or on the go. Wireless technology will continue to only get better, and in the IT world, more ways will be discovered to make connections even faster. Four wireless technologies that I will be discussing in this paper are the common ones that most people are familiar with: Bluetooth, Wi-Fi, Cellular and WiMax.

Wi-Fi is 802.11 wireless networking is used commonly in many public businesses and on many college campuses today. 802.11 specifically is used to create a WLAN that can be secured. Wi-Fi radios are used in many electronic devices such as cell phones, laptops, cameras, tablet PC’s, and printers just to name a few common devices. Best feature about this is everyone can have access to the Internet. To setup Wi-Fi, you still must use a wired connection to the Internet then the wireless routers sends and receives data to and from your electronic devices. As stated earlier, you can find many businesses using Wi-Fi such as Starbucks, your local library, most fast food restaurants, local colleges and universities, hotels, and airports.

Cellular is another popular wireless technology that is used today as well. We commonly use this with our cell phones that allow a user to move while staying in contact with the network. Even though while being in a large area and having more coverage, at times you may have calls that drop and those are referred to as dead zones or spots. Now there is 3G and 4G available mostly everywhere which allows faster connectivity. Most of the newer smartphones

...Wireless Communications are very important in our daily lives. Practically everywhere we turn we can see someone working away on a laptop, an iPad, or some other form of wireless PDA. This form of communication is usually used for personal and professional reasons. There are four main types of wireless technology in play here. The four types of wireless technology is Wi-Fi, Cellular, Bluetooth and WiMAX (Cox, 2013). Wi-Fi is the most popular form of wireless technology that we come to depend on today. Wi-Fi uses IEEE 802.11 specifications to provide secure network connections at home, in the office and in the public at places like libraries, coffee houses. Many business offices have Wi-Fi set up so that their employees can be more mobile using laptops they can retreat from their desk and in to a conference room for a quiet space to work. Wi-Fi connection within a network presents challenges for any IT group with regard to security as well as architecture of the network. Many wireless Routers and AP’s are designed to provide quick speeds and secure connection for Wi-Fi some more powerful than others. Many PDA devices are being designed to act as a hot spot, providing Wi-Fi access to laptops and other devices. This brings me to speak about Cellular technology. When we think of cellular technology, we mostly think about being on the go and needing to make a phone call with a wireless phone. Cellular signals use connected transmitters or cells as Michael Cox calls them to...

The electromagnetic spectrum is being exploited like no other time in history. With so many choices of wireless technologies to discuss, it is difficult to narrow them down to four. The four different types of wireless technologies to be discussed are cellular, satellite, Radio Frequency Identification, and Wireless Fidelity. Cellular communications are rapidly changing as more wireless applications are realized. The potential for cellular use has transcended mere phone communication use as developers delve into other cellular applications. Cellular technology works on the premise of radio communications through lower power base stations known as cells (Brain, Tyson, & Layton). The world has built an extensive and reliable cellular infrastructure and is now midst of significant improvement. With third generation (3G) and forth generation (4G) cellular communication, it is now possible to have mobile broadband technology. Other applications include WAN backup and alarm system transmission. An example of this is the use of 3G backup devices used in all State Farm agencies. This device is connected to the router in lieu of a dial backup. Satellite is another form of wireless technology. This digital signal transmits...

...Wireless Signals Raquel Barthelmes IT/242 September 30, 2012 Randy Guin   Abstract This is a short study of the different types of wireless technologies in common use today. This study will touch on only four types, although there are actually numerous types fulfilling many different uses. Wireless Signals Introduction In the world today, we have begun to rely heavily on various new technologies. Everything from the way our vehicles run to being able to spy remotely on our own houses can be done with the advances made in technology in the last few decades. One of the newest and most frequently used advances today is those that have been made in wireless technology, although that in itself is by no means new. The very first completely wireless system was patented by a man named Marconi in 1897(JPL’s Website, 1995), and a new future in communication was conceived. There are currently numerous wireless technologies available around the world which enable many tasks to be completed more quickly than ever before. From networking to opening a garage door, wireless technology has invaded the every-day lives of billions of people. Businesses are able to employ people to work remotely from home on a scale never before seen, which brings us to the first type of wireless technology I will outline here: Networking. Networking Wireless networking is perhaps the most commonly used type of wireless technology, primarily because every...

...Individual: Wireless Signals Erwin Pancho IT/242 June 17, 2012 Wireless Signals First of all lets define what a wireless signal is. Wireless internet/technology creates a network by sending radio-frequency signals between your computers to share information. This allows wireless networking technology to happen without the use of wires and makes it easier for other computers on the same network to communicate with one another. In wireless networking, a peer-to-peer or in other words point-to-point wireless network means that each computer can communicate with every other computer on that same network. Wireless networks that use client/servers have an access point. An access point is a wired controller that receives and transmits data to the wireless adapters installed in each of the computers. There are four main types of wireless technologies which include but not limited too are Bluetooth, IrDA, HomeRF, and Wi-Fi (wireless Fidelity). Bluetooth wireless technology allows users to enable links between their mobile computers, mobile phones, portable handheld devices, and Internet connectivity, which require no wires to be involved or that is needed. It is mostly used for devices such as cell phones, PDAs, wireless headsets, computer hardware, headphones, MP3 players, etc. Bluetooth technology is supported by application and product development in a broad range of market subdivisions, which include software developers...

...Wireless Signals June 29, 2011 IT242 Wireless Signals There are four different types of wireless signals in the spectrum. These are radio signals, microwave, satellite, and infrared signals. Each of these types has their proper uses as well as limitations. Radio frequencies include VHF, UHF, and shortwave radio. These are used to get a station on your car radio or to tune into a television station. Limitations of radio frequencies include distance degradation compared to bandwidth space in low frequencies. High frequencies tend to need a direct line-of-sight to get a good signal. Electrical equipment can interfere with all frequencies of radio signals. Microwave signals use electromagnetic energy to send signals at a higher frequency than radio. These signals are used in telecommunication, WIFI, and Bluetooth technology. As with radio communication, microwaves are also susceptible to interference from other electrical equipment. Satellite signals are relatable to microwave transmissions. A satellite is in orbit that sends and receives signals to receivers. The most common use for people are television, internet, and mobile telephone services. A major limitation that I run into is stability. When a storm comes through we can loose our signal due to line-of-sight issues. The final wireless transfer style is Infrared. IR systems use light to send signals. This type is used in remote controls, Palm devices, and laptops. The light...

...A CASE STUDY OF LOW CSSR ACCOMPANIED BY HIGH RF FAIL PROBLEM STATEMENT: In TIRUPATI MARKET ( Surat 1 MSC) The CSSR and RF fail rate were observed to be abysmally poor values during high call volume period. RESOLUTION STEPS: On inspection of Service Measurements for finding out the contributing factors for RF fail , nothing could be earmarked. All the conventional resources like Power, Packet pipe span, WC, RSSI rise were found within engineered values. That was as per expectation as the Block rate was not high . With this the RF environment was under doubt. Some extensive drive testing and coverage tuning was undertaken but could not yield any improvement. The mystery finally unfolded when we audited the LAPD SIGNALLING engineering ( between AP and BTS). It was found that the BTS which is MODCELL 4 having 4 FA was grown with 1 (64kbps wide) LAPD for each URC . In MODCELL 4 each URC is capable of taking upto 4 carries. When all the associated carrier signalling are imposed on a single URC the signalling load increases manifold and we need to increase the width of LAPD signalling between AP and BTS to 128 Kbps. It is recommended as per SCME ( Lucent DOC NO:401-610-009 Issue 27.0 sep 2004 Section 2-22 Modcell 4.0 (OneBTS) Engineering) that “Signaling Link Width Each fully loaded carrier needs 2 DS0s per signaling link per URC. Each URC supports 1 active signaling link and 1 standby/alternate signaling link. Therefore, if a URC is configured...

Gs-1140 Pst Micromouse Report 3

...Introduction The evolution of autonomous robots has inspired competitions worldwide, including the most notorious Micromouse Competition. This competition has existed for over 30 years in the United States and hasn’t changed much since the beginning. The goal is simple: the robot must navigate from one corner to the center as fast as possible. The actual final score is comprised of the total time in the maze and the time of the fastest run. The various components include techniques to streamline the methodology and make a proficient automated robot. Maze Solving Strategy The maze solving strategy is comprised of an algorithm. An algorithm is a step-by-step problem-solving procedure, especially an established, recursive computational procedure for solving a problem in a finite number of steps. The implementation The Group chose was a revised version of the bellman flooding algorithm. The algorithm requires around 256 X 3 bytes of memory. The selected microcontroller for implementation had only 256 KB of memory. We need to use software that has exceptional amounts of RAM and ROM memories. To solve the whole maze you will need to set the starting cell to the first cell in the maze. If you want to reverse the path traveled by the robot then you would set the target to the first cell, and the starting cell would then be the center or your current location. The problem statement has been simplified to three rules which we will follow to direct our robot to the center of the maze...

...biggest problem would be collision if multiple routers are using the same channel a common example of this is Comcast routers are set to use a channel close to the signal for the ps3 so you get a depredation of signal and loss of data packets as the connection goes on. 2. If a previously stated standard is not compatible with your adapter you could have issues with your connection not connecting Lab 6.3 Review 1. Um well I could write a book but simply a guest having access to your network could result in any imaginable results on your network to name a few rootkits,Trojan droppers, Remote Access Terminals, Keyloggers, Viruse’s. 2. Setting a MAC filter is a good way to filter who has access to your network its simply like saying Fred has access to the building with his fingerprint being scanned by a biometric scanner. Although this can be spoofed by spoofing your mac but you would still have to find out which macs are allowed and have to make sure the mac your spoofing is not connected so that you do not receive a duplicate error. Lab Review 6.4 1. A AP’s signal would fade naturally the farther from the signal source you go but with the signal going through walls will further degrade the signal depending on the thickness of the wall. So you would have to account for walls or objects that could further degrade your signal from the source. 2. A student in classroom b connect to AP3. The student in classroom A will connect to AP2.

Counterfeit Status Goods

...Consumers use product to signal status in different ways. They crave status and thus buy more accessible (less expensive), conspicuously branded goods that signal to those below and to other neophytes that they have arrived. But since, many consumers cannot afford authentic goods, they refer to buy counterfeit goods. A counterfeit good is one that seeks to imitate through the use of trademarks or other protected properties without the permission of the owner. Given that the cost of reproducing a brand image on a particular product is fairly low, counterfeit producers can easily duplicate the brand image to send the same signals. Counterfeit producers have lower costs of production that the original producers due to the inferior quality of counterfeits, avoidance of taxes and the lack of costs associated with brand development. It sustains costs arising from attempts to circumvent criminal prosecution and costs associated with creating copies. The demand for counterfeit status goods presents an intriguing paradox between consumption of counterfeit goods and the desire to send status signals. Consumers purchase counterfeit products to convey positive signal to themselves and to others. Particularly in the luxury goods market, consumers knowingly purchase counterfeit products as a social signalling mechanism with low financial costs. Implicit self-esteem is thought to play an important role in predicting status-signalling behaviours as it has been shown to affect materialism...

Tiger in the Tunnel

...The station, a small shack backed by heavy jungle, was a station in name only; for trains only stopped there, if at all, for a few seconds before entering the deep cutting that led to the tunnel. Most trains merely slowed down before taking the sharp curve before cutting. Baldeo was responsible for signalling whether or not the tunnel was clear of obstruction, and his manual signal stood before the entrance. At night it was his duty to see that the lamp was burning, and that the overland mail passed through safely. 'Shall I come too, Father?' asked Tembu sleepily, still lying in a huddle in a corner of the hut. 'No, it is cold tonight. Do not get up.' Tembu, who was twelve, did not always sleep with his father at the station, for he had also to help in the home, where his mother and small sister were usually alone. They lived in a small tribal village on the outskirts of the forest, about three miles from the station. Their small rice fields did not provide them with more than a bare living and Baldeo considered himself lucky to have got the job of Khalasi at this small wayside signal stop. Still drowsy, Baldeo, groped for his lamp in darkness then fumbled...
