Wireless Signals

There are many different types of wireless technologies accomplishing a wide variety of solutions as we trend toward a wireless world. 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 from the Clarke’s Belt approximately 22,000 miles above sea level (How Does Satellite Internet Work?, 2012). This geostationary orbit allows appropriate gravity for satellites to rotate at the same rate as the Earth. Satellite signals were predominately used for communication, but lately include Internet transmit and receive capabilities. A company can transmit and receive signals to and…...

...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......

...CHECKPOINT: SIGNALS Explain the differences between data, voice, and video signals in 200 to 300 words. Include a description comparing the differences between a private branch exchange (PBX) and Voice over Internet protocol (VoIP). The three types of signals data, voice, and video. Besides the obvious differences between these three signals there is more to them. The first signal I will describe is the video signal. Like the name suggest a video signal transmits videos from one point to another. They come in both analog and digital. These can be used by business to transmit videos to video monetors around a business to transmit information to employees. The next type of signal is the voice signal. According to the last weeks required reading, the voice signal, or audio signal, is responsible for supporting applications based on sound, usually of the human voice. (8text) What this basically means is that the audio that goes through a network through a Voice over Internet Protocol (VoIP) or a private branch exchange (PBX) is a voice signal. One of the differences between a PBX and a VoIP is basic function. A PBX is a system that in essence it is an internal telephone network that enables one office to call another office within the company. The company would only need to by one or two main telephone lines to connect to an outside line. So a business would save on money not having to supply each office with an outside line. A VoIP is similar to the PBX, but a......

...University of Phoenix Wireless Signals IT 242 Shana Roach February 23, 2014 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......

...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......

Smoke Signals

...October 26, 2013 There are several things that are important about the line, “He didn’t mean to Thomas,” that Victor speaks in the movie, “Smoke Signals.” The first thing that needs to be discussed is the fact that when this statement was made, Thomas and Victor had just returned to the Reservation from a trip to Arizona to retrieve the belongings of Victor’s father who had just passed away. This seems normal, but in fact, it was the last thing Victor wanted to do. You see, Victors father left the family years before he passed away when Victor was a young boy. This, coupled with the fact that Victor’s father was an alcoholic, was abusive to his wife and to Victor, left Victor with extreme anger issues towards his father on the one hand, yet on the other hand, a love that he kept inside of himself for his father also. Native American culture has many things passed along through the oral tradition of story telling. The story of what happened when Victor and Thomas were babies is a story that has been told over and over. Victor’s father was a hero; he saved Thomas’s life when, as an infant he was thrown from a burning house. To most people he was a great hero although Victor did not see his father as a hero, only as a drunk, and as abusive. While in Arizona getting his fathers belongings, Victor found out many stories about his father that he was unaware of. He did not know that his father had saved not only Thomas, but also Victor. He did......

The Signal Man

...The signal man The Story “The Signal-Man” describes an eerie encounter between two men, the anonymous narrator of the story and a railway signalman. The signalman confides to the narrator that he has seen some disturbing sights that he believes are ghostly apparitions. The story reflects the narrator's initial skepticism, which turns to horrified belief at the conclusion. The story opens as the narrator is taking a walk in the country. He sees a signalman by the train track at the bottom of a steep cutting. He calls to the signalman, makes his way down a zigzag path to the track, and converses with him. The signalman is strangely fearful of the man, revealing that the man's greeting reminded him of a disturbing supernatural apparition he has seen—and heard—at the mouth of a nearby tunnel. The narrator wonders briefly if the signalman himself is a spirit because of his strange manner. The signalman invites the narrator to return and meet him at his signal box on the following night. At that time, the signalman tells his visitor more about the apparition. It took the form of a man who appeared in front of the tunnel waving desperately and crying, “Look out! Look out!” The signalman telegraphed warnings to other stations along the line but to no avail. Six hours later, a terrible train accident occurred. On another day, the figure reappeared and assumed an attitude of extreme grief. A few hours later, a woman died on one of the trains going by the signalman's post. The......

...Signals IT/242 May 29, 2014 Sokly Vann Signals Today’s technology will use the old, the new and a combination of the two to achieve the desired results. Society has become dependent on this technology and the many types of signals that support it. Data, Voice and Video Signals all play a major role in the daily lives of millions of people around the world. They all seem to be alike but different. The Difference Data is a binary type signal that is be used in many different ways. Data is used in pictures, web sites, emails, programs and many other applications and software. Voice can be in the form of analog or digital signals. Depending on the application or use the frequency and bandwidth required may change to acquire the desired performance. Video signals also can be in the form of analog and digital (William Stallings/Pearson Education, Inc., 2009). VIOP and PBX Voice over Internet Protocol (VIOP) is the new technology in telephone systems. VIOP uses a packet switched network similar to the internet. VIOP passes digitized voice data. The advantage is more communication through the same amount of bandwidth. Public Branch Exchange (PBX) is a small telephone network within a company. This network has several lines to a local phone service to allow calls to go in and out of the company. The PBX internal calls are routed internally, and any calls to the outside take one of the available outside lines. VOIP can be used in a PBX system. This could be an......

...Introduction We have been hired to deploy a wireless network for Citizens First National Bank. We are going to design, test and deploy this network. Banks have been slow to adapt this technology because if the high security standards they must follow. Since security has been improved and the benefits are so great more and more companies are starting to deploy wireless networks. It the next couple pages I will go through the scope of the project along with the goals and requirements. There are some initial testing that we have to get down and setup so auditors will be able to test before we can deploy to all branches. By using auditors it helps protect the bank with a paper trail incase an incident ever happened. This would show that we have followed all requirements and made every possible attempt to protect our customers and employees. We will have 60 days to setup and test before we have to purchase equipment. This should provide plenty of time to get a location up and running and have their auditors in to do testing. After initial testing we will then put a plan in place to bring all branches online one at a time while sticking to the budget. Scope and Goals Scope The major driving force of this project is to add a wireless infrastructure to the entire bank that would allow seamless use between all branches, while maintaining the high security standards that the FCC requires to help protect the customers and employees of the bank.

...Explain the differences between data, voice, and video signals in 200 to 300 words. Include a description comparing the differences between a private branch exchange (PBX) and Voice over Internet protocol (VoIP).     Solution: Data signal is a mode of physical data transmission usually in binary code in signals or pulses from one source point to one or more destination point. Data is transformed into electromagnetic signals prior to transmission across a network. Data and video signal are typically encoded utilizing a digital methodology where voice is typically encoded utilizing an analog format. In analog technology, sound is recorded in its original form. Therefore, for instance, if making a recording of the sound, the audio is taken straight from the microphone and stored onto the storage media. The wave from the microphone is an analog wave, and therefore the wave on the tape is analog as well. That wave on the tape can be read, amplified and put through a sound system to produce the original sound. In digital technology, the video or data is turned into numbers that are stored on a digital device such as a computer. The more samples that are taken the more closely the digital data reflect the original data or video signal. Another option is that the data and video are directly encoded into digital format to start with and does not require sampling. In addition to this, Voice signals are generally less data intensive as only the audio part is captured and is......

...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......

Wireless Signals

...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......
