Cell Phones

Definition

A cell phone, also known as a mobile phone or cellular phone, is a type of short-wave analog or digital telecommunication in which the subscriber receives connection from the cell phone to a nearby transmitter. The span a transmitter covers is called a “cell”. As the cell phone moves from one cell or area to another, the mobile phone is passed on to the closer transmitter.
A cellular phone is not to be confused with a cordless phone which has short connection with the local phone outlet.

How Cell Phones Work

Parts of a Cell Phone

The cell phone is made up of several different components; the circuit board, antenna, LCD screens, a keyboard, microphone, speaker, and a battery. The circuit board is the brain of the cell phone; it keeps the phone working and allows for the rest of the parts to communicate. The antenna is important to the cell phone because it’s the part that connects the cell phone to a cellular network. The two types of antennae used in cell phone are external and internal. External are on the outside of the phone and internal antennae are built into the phone (internal antennae are more common in modern cell phones). LCD screens allow us to view information on the cell phone. The keyboard allows you to input data into the cell phone and dial numbers. The speaker and microphone are also important parts of the cell phone, they allow you to speak and listen to the person on the other line. The battery is the component that powers your cell phone; they can be recharged with AC and car chargers, battery sizes vary from cell phone to cell phone.

Cell Phone Frequencies

Most just know the cell phone as a simple device that calls. In fact, the cell phone’s closest ancestor is a radio.
Before the recent cell phone was released, people used a device known as the radio telephone in cars. The system consisted of one central antenna tower per city with approximately twenty-five channels. Because there were not many channels, only a few people could use the radio telephone at one time.
Soon enough, the radio telephone evolved into the cell phone we know today. One difference between radio telephone frequencies and cell phone frequencies is that cell phones have more towers with more channels allowing for more simultaneous use. In fact, cell phones can communicate on at least 1, 664 channels. Also, the cell phone is a full duplex device meaning each user is on a separate frequency contrary to a half duplex device (walkie-talkie) where two people communicating share a frequency. Finally, a cell phone has a much greater range than any other wireless communication device. Because the cell phone works within cells and can switch cells when necessary, a cell phone’s range is unbelievable.external image cell-tower-antennas.JPG
A typical, analog cell phone system carrier uses around 800 frequencies in one city. The carrier company then chops the city into cells that are hexagons about ten square miles in size. Each cell consists of a base station that has a tower and a small building with radio equipment.

Cell Phone Channels

To recap, cells in an analog cell phone system, each of which are ten square miles, cover an area in a hexagonal tessellation. Each cell includes one seventh of all the carrier’s available duplex voice channels. Because of this arrangement, the frequencies do not collide.
So, if each carrier has 832 frequencies per city and each call requires two frequencies, because it is a duplex channel, there are 56 voice channels per cell.
Next, cell phones have low power transmitters gaining two advantages over high power transmitters like a CB radio. First, because transmissions from phones and the tower can not travel a great distance outside of the cell, they may reuse the same signal. Also, low power transmitters do not consume as much battery life, batteries can be smaller allowing for smaller phones.

The SID and MTSO

Everyone knows each cell phone has a number, but what other codes are associated with the phone. These codes not only identify the user, but they also identify the phone’s owner and the service provider.
Even when you first turn on the phone, it searches for the SID (System Identification Code), a five-digit code that is assigned to each service carrier by the Federal Communications Commission on the control channel, a special frequency which the phone and base tower use to communicate with each other. If a phone cannot find the control channel, it is out of range and has no service.
Next, when the phone receives the SID code from the tower, it compares the code to the one stored in the memory. If the two match, then it acknowledges that it is communicating with the home system.
Also, as the cell phone is searching for an SID code, it transmits a registration request. This allows for the MTSO to store your phones location to be stored in the database, so when someone calls it knows which phone to ring.
After the MTSO locates your phone, it decides on which frequencies the call will occur. Then, the MTSO tells your phone (through the control channel) which frequency pair the call will be on. When the tower and phone switch onto the appropriate frequencies, the call is connected.
If you are moving during the call, the cell in which you are moving to monitors your signal’s increase while the base station in which you are notices the signal waning. Eventually, the two base stations communicate with each other through the MTSO to communicate when the call will switch onto the stronger frequency.
If the cell to which you are traveling is covered by a different server, the call is not dropped, rather it will be handed off to another service provider. If this happens, you are considered to be roaming.

The Differences between Analog and Digital Cell Phone Technology

Both of these types of communication technologies use radio technology. However, they use it in different ways.
Primarily, the difference is digital can fit more calls in one bandwidth. How, you ask? First, your voice is converted into binary code to compress it which allows three to ten times more calls than an analog service.
Some digital systems use a process known as frequency-shift keying(FSK) to send data between AMPS. This process uses two frequencies, one for 1s in the binary code and another for the 0s in the binary code. Because of the two frequencies, FSK must switch rapidly between the two in order to relay the information from phone to tower and vice versa.

Inside a Cell Phone

A cell phone contains the following:
· A Circuit Board: The circuit board is the brain of the phone. Some examples of chips located on the circuit board are the analog-to-digital chip which translates your outgoing, analog message to digital, the digital single processor which performs single-manipulation calculations quickly, and the microprocessor which helps operate the LCD and keyboard and does other functions.
· An LCD screen: The screen displays information.
· A Keyboard: The keyboard is an input device.
· A Microphone: The microphone is also an input device.
· A Speaker: The speaker lets you hear information and is about the size if a dime.
· A Battery: The battery powers the phone.



History of Cell Phones

Inventor of the Cell Phone: Martin Cooper

Martin Cooper was born on December 26, 1928 in Chicago, Illinois. He grew up during the Great Depression, and his parents were Ukrainian immigrants. In, 1950 he got his undergraduate degree in Electrical Engineering from the Illinois Institute of Technology. Before his life in technology, he joined the Reserve Officer Training Corps. He served as on a US Navy Destroyer during the Korean War. After the war, Cooper started working with Teletype. He then moved to Motorola in 1954. While working at Motorola he was still able to go to school. He ended up getting his Master’s Degree in Electrical Engineering. In 1960, Cooper fixed the flaw in the crystals Motorola made for its radios. With this step forward it allowed them to mass-produce the first quartz crystals to be used in watches. After Cooper’s outstanding work in the Company he was promoted to the head of the car phone division, but Cooper was thinking much farther ahead then just a car phone. He knew that he could make a device small enough and light enough to be made portable. In 1973, Cooper started working on his invention. It only took him 90 days to make his first prototype.

Cooper, his engineers, and his boss, John Mitchell, were named on the patent “Radio Telephone System” filed on October 17, 1973. Cooper was officially named the inventor of the first. portable cell phone on April 3rd. Cooper said that he was inspired to make his invention by watching Captain Kirk use his communicator on the show Star Trek. When the 1st Cell Phone came out the listing price was $4,000. Cooper ended up leaving the company before they ever started selling his creations though.In 1992, Cooper joined Richard Roy and Arnaud Saffari in the company ArrayComm. This company started creating more efficient cell phones.

The First Mobile Phones

The cell phone’s origins can be traced back to the two way radios used by the police. The first mobile phone was used by the Swedish police in 1946, unfortunately, this phone ran off of the battery of the car it was installed in, and it only took six calls to drain the battery. In 1947, D.H. Ring from Bell Labs created an important part of modern cell phones: the hexagonal cell. Later, another engineer from Bell Labs had the idea of making radio towers transmit in three directions, rather than only two. In 1967, mobile phones were widely available, but could only send and receive calls if both phones were within a certain area; if either phone moved outside this area, the call would disconnect. In 1970, the technology for transferring calls from one area to another was developed, but was not put into use until 1982.

How the Cell Phone Has Changed

The Motorola Company released the first “cell” phones (First Generation) in 1983 that used analog technology. These phones were used in vehicles such as police cars or trucks, and were permanently placed in the floorboards of the automobiles. When these phones were accessible beyond that of the car, they were large and inconvenient. The use of these phones was used mostly for “voice traffic,” but people were feeling uncomfortable with others being able to hear there conversations. In 1990, the Second Generation phones that used digital technology were used, and the first phone call was made. It was faster and quieter than the first generation phones, and therefore became more popular. They became smaller and used more energy efficient applications. The Third Generation is what is most commonly used today. It uses digital technology and can send not only voice data, but also other things such as e-mails and internet. There are researchers who are working hard to start making a fourth generation phone that will bring the user these applications faster.



Specifications

The specifications of cell phones involve the different abilities and tools each different phone can carry out. The specifications depend on the carrier and the model. Some of these include color, weight, camera/video capability, battery life, model case, and memory ability.

Specification options for phones have changed greatly over the years. They have evolved from having a camera in the phone being the newest and greatest thing to 3G technology and entertainment qualities. 3G coverage stands for 3rd generation. This means that the network coverage works faster, and has more advanced capabilities. The invention of the 3G makes cell phones more unique and advanced than they already were becoming.

Today you can choose from many different specification options such as Internet, television, mp3 abilities, e-mailing and Bluetooth (used for sending information over short distances). These specifications are more luxurious to the user. Not every cell phone has the ability to use these different specifics. It depends on the make of the phone, the carrier, and the model’s ability to process. Using the TV, GPS, radio, etc can take much battery, and their reliability is always questionable. The price of these also determines the quality of the phone and the reliability of the network. These options are not required by as many people don’t want or need them and they make the phone fairly expensive. This makes the price of the cell phone one of the most concerned specifics of the phone.

Aside from cell phone usages, the colors have gotten a large variety and change as well. Starting from colors like silver and black, they have gone to more vibrant colors such as orange and green. Designs and patterns have also been influenced by media and the ever-changing style of the general consumers. Cases for the outside of the phone have changed the way cell phone designs are seen. These outer cases that are purchased separately are usually based on the way cell phones operate: whether they flip, slide, or show their numeric keypad only.

The way cell phones open and close are also an important factor for buying a cell phone to most people. Cell phone covers flip, slide, or do not exist at all in some cases. Cell phones recently have developed a full keyboard, used mostly for texting that slides in and out. Most consumers prefer the full keyboard because it gives them the freedom to type whatever they want too, without spell ch eck. Same with the touch-screen technology, which have eliminated the use of keys all together, like Apple’s iPhone. The size and portability of cell phones plays an important role, based on the user’s preferences.

Most companies will give you a chart including the information regarding the different categories of each specification. These charts can be easily found on the companies website or in the store where you buy it. This becomes very useful in finding the phone that is most useful to the user’s need.

History

Verizon Wireless is one of the older cell phone carriers, first started in around 1995. This company has roots in Bell Atlantic Mobile, NYNEX Mobile Communications, AirTouch Communications, PrimeCo Communications, and GTE Mobilnet. From these roots, Verizon emerged from the combination of Bell Atlantic Mobile and AirTouch Paging in 1999.Later on in 2000, GTE Wireless added its assets to make Verizon Wireless the largest cell phone servicer until 2004, when AT&T was bought by Cingular. In 2009, Verizon acquired Alltel, bringing them back to the largest cell phone provider. Verizon is a unique company, formed from two Latin words: "veritas," meaning "truth," and the word "horizon." This combined word is supposed to symbolize ideas of reliability, dependability, leadership, and unlimited possibilities.

Network

Verizon has a very unique network, and uses CDMA technology. It is one of the two major companies to use this, the other being Sprint Nextel. To maintain and expand its nationwide CDMA network, costs Verizon Wireles s $8 billion annually.

Different Types of Cell Phones:

Camera phones

Today with the multiple types of cell phones the most common is the camera phone. The camera phone allows you to capture pictures with a camera placed on your phone, and not only can you keep the good times with yourself; you can share them with everyone. Being the most popular phone on the market, pictures are shared between friends and family. Clearly with the percentage of people owning camera phones, it’s a good buy. The best part about camera phones is every company has many styles to choose from. The largest concern is the camera quality. With every new design, the camera quality improves, and with newer, better qua

lity, the price follows. Out of all the various types of cell phones camera phones are the best buy. A camera phone is a great phone to invest in. Today cameras are placed on almost every phone, whether it’s a phone made for texting, emailing, or music. Camera phones are the best and most popular type of cell phone.

Mp3 or Music phones

Another common phone that is widely used around the world it an mp3 phone, which allows you to upload, or buy music, and then listen to it, similar to an iPod. The reason p3 phones are popular is because of the ability to have your music and your phone, with out having to carry an iPod. People all around the world listen to and enjoy music. Another reason for the popularity of the mp3 is because of the customization attribute, the ability to upload what you want and how much you want of it. Although it cannot hold quite as m uch as an average iPod, it can still hold enough. Today with smart phones in use, mp3 phones are not a common. Mostly because of the phones such as the iphone which have as much space as an iPod, and a phone. Despite the smart phones of today, mp3 phexternal image nokia_e71_4.jpgones are still in use.

PDA
There are many different types of cellular devi

ces. The most common type among users is the analog service phone which can be most useful for occasional use. Another type of cellular phone is the digital phones which are most commonly used by small business owners, marketers, etc. The digital phone also has much better safety and security services. Other types of cell phones are those consisting of PDA phones, Camera phones, Smart Phones, Music/MP3 phone, and of course the basic phone. These days there are many different types cell phones on the market, it is up to the consumer to decide which one is best for them.
Personal Digital Assistant (PDA) is designed to provide the consumer with an open range of digitally enlarged services of communication features such as: cell phone services, internet connectivity, email, text messaging, calendars, electric files, and

other elements of organization. As life goes on the PDA list of features can really become endless because of its rapid growth among users. This being said there may be many other features not listed in the previous examples given. A PDA is a real useful device that replaces the ideal cell phone with much needed features. It is highly thought that once you get a PDA a phone you’ll wonder how you ever lived without one.




Smart Phones

Features

The latest type of communication technology is the smart phone. It is leading the pack of the new field of communication gadgets. Smart phone are very expensive and should be looked at in many sources such as the Internet before purchase. There are even web sites today that operate solely with the dealing of expensive phones for a reduced price. However sometimes you can go to the retail stores and receive a discount or be eligible for an upgrade.

The Smart phone is a phone that can do all the capabilities of a normal camera phone but has many unique characteristics that personalize your phone. For example receive a normal e-mail template, Microsoft Office and PDA features. Smart phone have operating systems like computers that allow them to acce

ss a variety of apps. Another feature of Smart phone is they are software compatible which allows the phone to do a variety of unique things. Smart phone can operate the World Wide Web at rapid speeds due to the original 3G technology and WIFI. All smart phones contain some kind of internet. Most smart phones also include the best standard of texting which is QWERTY keyboard (Computer Keyboard Format). Most phones have the basic form of communication technology; however smart phones have emails and chat identical to using a computer. They can handle email accounts for important people and connect with your usual account.






Uses of Cell Phones


Cellular devices have acquired many different uses over the years. The idea of a phone only being used as a means of communication has evolved entirely. Today’s cellular devices not only have the standard mob ile telecommunications, but additional functions such as
Global Positioning Systems and even internet.

Mobile Telecommunication

The main function of a mobile phone is to communicate, from a mobile device, with other devices and people around the world. Everyone can use cellular phones to communicate with one another; adults to adults, parents to children, and teens to teens. Cell phones are also the essential part of many businesses and companies in order to communicate over long distances outside of the office.

Texting (SMS)

Calling was the main feature of cell phones until texting came about. Texting is the exchange of brief written messages between mobile and portable devices over cellular networks. It is also a convenient way to communicate with other people without vocally communicating. You can send pages with the words that you would normally say and the other person can read the message once they receive it. Text messaging can also be used to send pictures in files call MMS.

Applications

The cellular phone today has ma ny different aspects that do not include talking to another person on the other line. The new features on the cell phone in this age include apps, music, and games. All of these features make the phone better and more attractive to the buyers needs in what kind of phone they would like to get. The kinds of phones that have theses features just talked about are Blackberry, Iphone, and Droid (etc). These are all examples of phones of high quality features. But looking in to the features you find that it makes the user’s phone life easier.
Here are some of the features explained the music feature allows the user to access their favorite music that have selected from at their own connivance. This feature allows the user to store as many songs as they would like depending on the phone. Another one the features is the browser for the internet this allows the user to access email, Facebook, and whatever they desire at the time. This is a great aspect on the phone that’s gives the comfort in knowing they can get what they need. The games are also a great addition to more use of the phone today. This aspect is widely used on the Iphone because of the many games or apps available to buy. The use of the phone is very great and the features on the phone have a great impact on the way we live our lives.

Commercial Uses

Cellular Phones can also be used commercially. Many companies and businesses can send SMS messages to a mobile device in order to advertise their business or event. Cell phones can also be used to help raise money for causes by sending text messages and calls to certain numbers to help make donations. One of the more popular uses for cell-phones that has started recently is calling and texting in order to vote for contestants on many shows like American Idol.

GPS (Global Positioning System

In today’s society a paper map can rarely be fo und. A trend

has swept the nation and that is a computerized Global Positioning System. GPS is based off a global navigation satellite system. It offers positioning and navigation to users all over the world. With so many people taking hold of this new technology, cellular companies have also decided to join the fad by adding this to their list of utilities.With the GPS now in people’s everyday cell phones, (for a certain price) many new uses of it have surfaced. Technology has allowed concerned parents to track their children or elderly relatives through companies like uLocate Communications or TrimTrac Mobile. It is also used for directions and destination estimates while driving. Another common and practical use of the GPS in cell phones is the idea of locating personal likes and dislikes. GPS can locate certain restaurants and venues in the area you wish to find. Therefore, GPS can essentially serve as a personalized scrapbook of all the locations that are your favorite. Most importantly it allows for an emergency response team to pinpoint your exact location incase you are ever in need of assistance. Global Positioning Systems are paving the way to a safer and more efficient world and their addition to cell phones is only hastening the process.



Future Uses

Although the future of cell phones is not clear, we can all guess at how they will evolve. A new idea for a cell phone is the Nokia Morph. They are planning for it to be able to fold up for keyboard use and even be able to scrunch up like a watch around your wrist. Also in the future of cell phones is the ability to offer more games, be a full TV, and be used as a credit card. How cool is that?! Companies are working to make the internet connections more like a laptop, and they are working out a way to make cable work on a cell phone. Improvements are being made to the camera capability. In the years to come, you can expect cell phones to become, sleeker, faster and more efficient!
