The history of mobile phones begins with early efforts to develop mobile telephony concepts using two-way radios and continues through emergence of modern mobile phones and associated services.
Radiophones have a long and varied history going back to Reginald Fessenden's invention and shore-to-ship demonstration of radio telephony, through the Second World War with military use of radio telephony links and civil services in the 1950s, while hand-held mobile radio devices have been available since 1973. Mobile phone history is often divided into generations (first, second, third and so on) to mark significant step changes in capabilities as the technology improved over the years.
Cellular concepts
In December 1947, Douglas H. Ring and W. Rae Young, Bell Labs engineers, proposed hexagonal cells for mobile phones in vehicles.[2] Philip T. Porter, also of Bell Labs, proposed that the cell towers be at the corners of the hexagons rather than the centers and have directional antennas that would transmit/receive in three directions (see picture at right) into three adjacent hexagon cells.[3] At this stage the technology to implement the ideas did not exist nor had the frequencies had been allocated and it would be some years until Richard H. Frenkiel and Joel S. Engel of Bell Labs developed the electronics to achieve this in the 1960s.

Cell Phones may be Harm Phones !!
It has become quite common to see people talking on their cell phones just about everywhere you go. The cell phone industry has been very effective at selling people on the convenience and coolness of being connected and reachable no matter where they are.
Project 10 to 15 years into the future. By that point the “cell phone epidemic” may have claimed many lives through cancer, Alzheimer’s, strokes, auto accidents, and other consequences of regular cell phone usage; unless the present level of use is cut dramatically.
If people knew that they were undermining their own health as well as the health of those around them when they use a cell phone, would the devices be as popular?
Probably not; that is why you have not heard much about the hazard of cell phone use. Just like the tobacco companies who stonewalled against the idea that cigarette smoking is harmful to health, the cellular companies are keeping cell phone dangers from being known.
Further, the major media have not presented much information on cell phone radiation either. As you know, millions of dollars are spent on the advertising of cellular service and equipment.
Do you think the government would intervene if cell phones are harming people? How many years did it take before the government required warning labels on cigarettes?
What about chlorine, a known poison, being added to every city’s water supply to kill microbes? Do they warn you about the long term negative health effects of that?
If something is a big business, and it offers benefits that the marketplace supports, and it is not immediately destructive, the government tends to let it go, even though it may be hurtful over a long period of time.
What you don't know CAN hurt you. Ignoring the information on cell phone problems could have much graver consequences than just being ignorant. It is time to learn about the cell phone hazard now, before it is too late.
In Europe this would be called mobile phone harm, or mobile phone danger, or the mobile phone problem. Mobile phone radiation is the same as cell phone radiation, and it is not good for anybody.
WARNING: Cordless portable phones in your home are just as bad if not worse. Other electronic devices put out harmful electromagnetic fields also.

Future of Cell Phones
What's Next: Speed Is Just the Beginning
Today's mobile phones can already send e-mail, browse the Web, and keep you in touch with friends and colleagues via voice or text message. Tomorrow's handsets will add even more to the menu, morphing (as needed) into always-connected portable game consoles, full-featured TVs, and credit cards. Here's a quick look at what's coming:
Networks: In the next few years, cell phone networks will move data at several megabits per second, and will coexist with WiMax, Wi-Fi, and, for TV, DVB-H or MediaFLO. IMS will let them work together.
Handsets: Look for sleek designs (such as Frog Design's Ubik), better battery life, e-payment support, and graphics muscle for true TV and console-style video gaming.
Cameras: Expect not just high resolutions (8 megapixels and beyond), but also the same image-processing capabilities found in current digital still and video cameras.
Network Hopping: Enabling Seamless Internet Access
GSM, CDMA, Wi-Fi, WiMax: Can't we all just get along? With IMS (IP Multimedia Subsystem), we just might. Now in trials, IMS network technology will allow any type of packet data--voice calls, video, music, HTML, you name it--to move seamlessly between IMS-enabled networks. With IMS, you'll be able to start a call on your cell phone and end it on a VoIP landline, watch pay TV on either a handset or a big screen (smart-card technology identifies you), and access your contacts from any connected PC or handset. But the benefits will kick in only once IMS is widely deployed, which will take several years.
Tomorrow's Phone: Fold It and Go
Artwork: Courtesy of Frog Designs Many of today's hot new phones started out as just a glimmer in an industrial designer's eye. The most successful of these new designs are picked up by handset manufacturers and eventually offered to you by your cell phone service provider.
We asked Frog Design, the Silicon Valley industrial design and consulting firm with clients as diverse as Victoria's Secret, Maxtor, and Yahoo Music, what a cell phone might look like several years from now. They shared with us this innovative prototype design. Click on the image to see more features.

Nokia E7 - silver white
The good: The Nokia E7 boasts a premium design and has a fantastic QWERTY keyboard. The smartphone's 8-megapixel camera takes excellent pictures and video. Battery life is also good.
The bad: The Symbian platform falls short of the competition, and the phone can be sluggish. The E7 has a lower-resolution display and doesn't have an expansion slot.
The bottom line: The Nokia E7 has some wonderful qualities, like great hardware and excellent battery life, but ultimately its inferior software trips up this business-oriented smartphone.
If you've been a cell phone fan for a while, you might remember the days when the Nokia Communicator series was the status symbol of a powerful businessperson. Nokia eventually developed the line into the E series, and its latest flagship model, the Nokia E7, is available now for an unlocked price of $650. The company has done a lot to refine the design, and it's running the revamped Symbian 3 operating system. However, a lot has changed since the days of the Communicator. Does the E7 have the chops to make it in the business world? Read on to find out.
Design
The Nokia E7 takes a number of style cues from the Nokia N8, which isn't a bad thing in our view since we loved the N8's hardware. The E7 is made of the same high-quality materials--aluminum body and glass AMOLED display--giving it a very premium feel. It's slightly bigger and heavier than the N8 at 4.87 inches tall by 2.46 inches wide by 0.54 thick and 6.2 ounces, but considering that the E7 also manages to fit in a full QWERTY keyboard, it's actually pretty amazing that it's only 0.03 inch thicker and 0.1 inch longer than the N8.
The E7's glass touch screen measures 4 inches diagonally and has a 640x360-pixel resolution. In general, it's clear and bright and you'll have no problem reading what's on the screen. However, with a lower-resolution screen, you're not going to get the same sharpness or definition as on today's qHD, Super AMOLED, and retina displays. The pixels are more visible on the E7, so images and text don't look quite as smooth.
On the bright side, the touch screen is very responsive. Launching apps only required a single tap, and we were able to navigate through the various screens and menus with no problem. There are three home screens in total, which you can customize with various widgets and shortcuts, and the main menu of apps is presented in a simple grid format.
Of course, as we've stated before in our reviews of the N8 and the Nokia Astound, Symbian 3 brings a one-touch user interface that makes it much easier to navigate these phones than previous versions of the operating system. However, it still feels clunky in some parts compared with platforms like iOS, Android, and Windows Phone, so Symbian certainly isn't leapfrogging the competition.
For text entry, you get an onscreen keyboard, though in portrait mode you only get an alphanumeric keypad. It's not as big of a deal as it was on the Nokia N8, since the E7 offers a full, physical QWERTY keyboard. To access it, you simply push the screen aside. The sliding mechanism is smooth and the hinge feels sturdy. The screen securely locks into place and sits at a slight angle to make it easier to see when using the keyboard.
Nokia did a really nice job with the keyboard. The buttons are a decent size with good spacing and a comfortable layout. The space bar is centrally located and not off to the side as on the Nokia N97 Mini, so in general we were able to type at a good clip with minimal mistakes.
There are a handful of other controls on the smartphone. Just below the display, there's a menu button. The left side features a lock switch and on the right side you'll find the SIM card slot, a volume/zoom key, and a camera button. Like the N8, the E7 doesn't have a user-replaceable battery, so you insert the SIM card on the side. However, we initially had a rather difficult time pulling out the SIM card tray, and after about 20 minutes we finally pried it open with a sharp object. Also, the slider volume controls take a bit of getting used to; we found it easier to use a rocker control to adjust audio while on a call, but this is really a minor issue.
The top of the phone houses the 3.5mm headphone jack, power button, HDMI port, and Micro-USB port. Note that there is no expansion slot on the E7. Last but not least, the 8-megapixel camera and dual LED flash are on the back, and the front-facing VGA camera is located above the display in the upper left corner.
The Nokia E7 comes packaged with an AC adapter, a USB cable, a wired stereo headset, an HDMI cable, a Micro-USB-to-USB adapter, and reference material. The smartphone is available in five colors: dark gray, silver white, green, blue, and orange.

How Cell Phones Work ?
Millions of people in the United States and around the world use cellular phones. They are such great gadgets -- with a cell phone, you can talk to anyone on the planet from just about anywhere!
These days, cell phones provide an incredible array of functions, and new ones are being added at a breakneck pace. Depending on the cell-phone model, you can:
-Store contact information
-Make task or to-do lists
-Keep track of appointments and set reminders
-Use the built-in calculator for simple math
-Send or receive e-mail
-Get information (news, entertainment, stock quotes) from the Internet
-Play games
-Watch TV
-Send text messages
-Integrate other devices such as PDAs, MP3 players and GPS receivers
But have you ever wondered how a cell phone works? What makes it different from a regular phone? What do all those terms like PCS, GSM, CDMA and TDMA mean? In this article, we will discuss the technology behind cell phones so that you can see how amazing they really are. If you are thinking about buying a cell phone, be sure to check out How Buying a Cell Phone Works to learn what you should know before making a purchase.
To start with, one of the most interesting things about a cell phone is that it is actually a radio -- an extremely sophisticated radio, but a radio nonetheless. The telephone was invented by Alexander Graham Bell in 1876, and wireless communication can trace its roots to the invention of the radio by Nikolai Tesla in the 1880s (formally presented in 1894 by a young Italian named Guglielmo Marconi). It was only natural that these two great technologies would eventually be combined.

Cell-phone Frequencies
In the dark ages before cell phones, people who really needed mobile-communications ability installed radio telephones in their cars. In the radio-telephone system, there was one central antenna tower per city, and perhaps 25 channels available on that tower. This central antenna meant that the phone in your car needed a powerful transmitter -- big enough to transmit 40 or 50 miles (about 70 km). It also meant that not many people could use radio telephones -- there just were not enough channels.
The genius of the cellular system is the division of a city into small cells. This allows extensive frequency reuse across a city, so that millions of people can use cell phones simultaneously.
A good way to understand the sophistication of a cell phone is to compare it to a CB radio or a walkie-talkie.
Full-duplex vs. half-duplex - Both walkie-talkies and CB radios are half-duplex devices. That is, two people communicating on a CB radio use the same frequency, so only one person can talk at a time. A cell phone is a full-duplex device. That means that you use one frequency for talking and a second, separate frequency for listening. Both people on the call can talk at once.
Channels - A walkie-talkie typically has one channel, and a CB radio has 40 channels. A typical cell phone can communicate on 1,664 channels or more!
Range - A walkie-talkie can transmit about 1 mile (1.6 km) using a 0.25-watt transmitter. A CB radio, because it has much higher power, can transmit about 5 miles (8 km) using a 5-watt transmitter. Cell phones operate within cells, and they can switch cells as they move around. Cells give cell phones incredible range. Someone using a cell phone can drive hundreds of miles and maintain a conversation the entire time because of the cellular approach.
In half-duplex radio, both transmitters use the same frequency. Only one party can talk at a time.
In full-duplex radio, the two transmitters use different frequencies, so both parties can talk at the same time.
Cell phones are full-duplex.
In a typical analog cell-phone system in the United States, the cell-phone carrier receives about 800 frequencies to use across the city. The carrier chops up the city into cells. Each cell is typically sized at about 10 square miles (26 square kilometers). Cells are normally thought of as hexagons on a big hexagonal grid, like this:
Because cell phones and base stations use low-power transmitters, the same frequencies can be reused in non-adjacent cells. The two purple cells can reuse the same frequencies.
Cell-phone Channels
A single cell in an analog cell-phone system uses one-seventh of the available duplex voice channels. That is, each cell (of the seven on a hexagonal grid) is using one-seventh of the available channels so it has a unique set of frequencies and there are no collisions:
A cell-phone carrier typically gets 832 radio frequencies to use in a city.
Each cell phone uses two frequencies per call -- a duplex channel -- so there are typically 395 voice channels per carrier. (The other 42 frequencies are used for control channels -- more on this later.)
Therefore, each cell has about 56 voice channels available. In other words, in any cell, 56 people can be talking on their cell phone at one time. Analog cellular systems are considered first-generation mobile technology, or 1G. With digital transmission methods (2G), the number of available channels increases. For example, a TDMA-based digital system (more on TDMA later) can carry three times as many calls as an analog system, so each cell has about 168 channels available.
Cell phones have low-power transmitters in them. Many cell phones have two signal strengths: 0.6 watts and 3 watts (for comparison, most CB radios transmit at 4 watts). The base station is also transmitting at low power. Low-power transmitters have two advantages:
The transmissions of a base station and the phones within its cell do not make it very far outside that cell. Therefore, in the figure above, both of the purple cells can reuse the same 56 frequencies. The same frequencies can be reused extensively across the city.
The power consumption of the cell phone, which is normally battery-operated, is relatively low. Low power means small batteries, and this is what has made handheld cellular phones possible.
The cellular approach requires a large number of base stations in a city of any size. A typical large city can have hundreds of towers. But because so many people are using cell phones, costs remain low per user. Each carrier in each city also runs one central office called the Mobile Telephone Switching Office (MTSO). This office handles all of the phone connections to the normal land-based phone system, and controls all of the base stations in the region.

Today's cell phones are much more than communications devices: they have become portable computers. Some have mobile games that are so cool they may relegate the classical "phone" functionality of your handset to a close second place.
Antennas
Problems getting reception? Some phones and services struggle with the reception of a signal depending on where you live or travel. An antenna booster may be necessary for you.
Antiradiation
Mobile phones are two-way radios that transmit and receive information via radio waves, also known as radio frequency (RF) energy. Whenever the user makes a phone call, his voice is encoded into radio waves and transmitted through the antenna to a nearby base station. These radio waves are at the heart of the controversy over cell phone safety.

10 Cell Phone Radiation Protection Tips
"The voluntary exposure of the brain to microwaves from mobile phones to hand ... [is] the largest zoqmg123 human biological experiment ever."
~ Professor Leif Salford, Head of Research at the University of Lund, Sweden

"The voluntary exposure of the brain to microwaves from mobile phones to hand ... [is] beats by dre pro the largest human biological experiment ever."
~ Professor Leif Salford, Head of Research at the University of Lund, Sweden
There is now estimated at 208 million cell phone users in the U.S. alone, 1.9 million worldwide. Scientists fear that we are on the verge of a health crisis of epidemic proportions. Dr. George Carlo, former chief scientist of the 28 million cell phones up industrial research plans 500,000 new cases of brain cancer and eye each year from 2010 cell phone use (currently there are 30 to 50,000 cases per year).
Studies have linked cell phone radiation health problems such as headaches, hypertension, brain tumors, cancer, Alzheimer's, and more. It is a latency period for most diseases and can take years and more studies before the test is established. But the beat by dre usa effects are cumulative, and should be taken before it is too late.
Here are some steps you can take to minimize the effects of radiation from mobile phones:
1. Limit the use of essential calls and keep calls short. Even a two-minute call was found to alter the natural electrical activity of the brain until an hour later.
2. Children should be able to use a cell phone in emergencies only. Since the development of their skulls, the radiation can penetrate much deeper.
3. Wear a helmet airtube (not regular wired headset). The normal wired headset has been found to intensify radiation into the ear canal. The cable carries not only the cell phone radiation, but also serves as an antenna attracting EMFs (electromagnetic fields) from the environment
4. Do not put your phone in your pocket or belt during use or when it is turned on. The tissues of the lower body is good and absorbs radiation more quickly head. One study found that men who use cell phones near their groin could have their sperm count dropped by as much as 30 percent.
5. If you use the phone without a headset, wait for the call to connect before placing the phone near your ear.
6. Do not use the cell phone in enclosed spaces such as metals, vehicles or elevators, where devices may use more power to connect. The metal enclosure also acts as a Faraday cage that traps the radiation and sends it back to residents.
7. Do not make a call when the signal strength is one bar or less, which means the phone must work harder to establish a connection.
8. Purchase phone with low SAR (Specific Absorption Rate). Most cell phones have a SAR level listed in the manual. SAR is a way to measure radio frequency (RF), which is absorbed by the body. Lower the number, the better. (Note, however, that studies the RF hundreds of times smaller than current SAR limits still have biological effects.)
9. Use a device scientifically validated EMF protection. Advanced technologies are available today to strengthen their bioenergy field and immune system against the effects of electromagnetic fields. The electromagnetic radiation causes a problem only when the cumulative effects due to repeated exposure to weaken the body's ability to repair itself. Even when not using the cell phone radiation "second-hand and other EMF devices can also cause biological stress, so these types of devices are becoming increasingly essential.
10. Take nutritional supplements, particularly antioxidants, SOD, catalase, glutathione, and CoQ10. microwave radiation has been shown to reduce levels of antioxidants in the body. These are substances the body produces to protect themselves and their levels are sensitive indicators of stress, aging, infections and various other diseases. Other supplements you might need are:
- Melatonin: a potent anti-oxidant said to prevent DNA breaks in brain cells. As effective in preventing kidney damage, cell phones;
- Zinc: protects the oxidation of the eyes and helps maintain the levels of antioxidants in the blood;

worldwide. Scientists fear that we are on the verge of a health crisis of epidemic proportions. Dr. George Carlo, former chief scientist of the 28 million cell phones up industrial research plans 500,000 new cases of brain cancer and eye each year from 2010 cell phone use (currently there are 30 to 50,000 cases per year).
Studies have linked cell phone radiation health problems such as headaches, hypertension, brain tumors, cancer, Alzheimer's, and more. It is a latency period for most diseases and can take years and more studies before the test is established. But the effects are cumulative, and should be taken before it is too late.
Here are some steps you can take to minimize the effects of radiation from mobile phones:
1. Limit the use of essential calls and keep calls short. Even a two-minute call was found to alter the natural electrical activity of the brain until an hour later.
2. Children should be able to use a cell phone in emergencies only. Since the development of their skulls, the radiation can penetrate much deeper.
3. Wear a helmet airtube (not regular wired headset). The normal wired headset has been found to intensify radiation into the ear canal. The cable carries not only the cell phone radiation, but also serves as an antenna attracting EMFs (electromagnetic fields) from the environment
4. Do not put your phone in your pocket or belt during use or when it is turned on. The tissues of the lower body is good and absorbs radiation more quickly head. One study found that men who use cell phones near their groin could have their sperm count dropped by as much as 30 percent.
5. If you use the phone without a headset, wait for the call to connect before placing the phone near your ear.
6. Do not use the cell phone in enclosed spaces such as metals, vehicles or elevators, where devices may use more power to connect. The metal enclosure also acts as a Faraday cage that traps the radiation and sends it back to residents.
7. Do not make a call when the signal strength is one bar or less, which means the phone must work harder to establish a connection.
8. Purchase phone with low SAR (Specific Absorption Rate). Most cell phones have a SAR level listed in the manual. SAR is a way to measure radio frequency (RF), which is absorbed by the body. Lower the number, the better. (Note, however, that studies the RF hundreds of times smaller than current SAR limits still have biological effects.)
9. Use a device scientifically validated EMF protection. Advanced technologies are available today to strengthen their bioenergy field and immune system against the effects of electromagnetic fields. The electromagnetic radiation causes a problem only when the cumulative effects due to repeated exposure to weaken the body's ability to repair itself. Even when not using the cell phone radiation "second-hand and other EMF devices can also cause biological stress, so these types of devices are becoming increasingly essential.
10. Take nutritional supplements, particularly antioxidants, SOD, catalase, glutathione, and CoQ10. microwave radiation has been shown to reduce levels of antioxidants in the body. These are substances the body produces to protect themselves and their levels are sensitive indicators of stress, aging, infections and various other diseases. Other supplements you might need are:
- Melatonin: a potent anti-oxidant said to prevent DNA breaks in brain cells. As effective in preventing kidney damage, cell phones;
- Zinc: protects the oxidation of the eyes and helps maintain the levels of antioxidants in the blood;
- Gingko biloba: herbal considered a powerful antioxidant that prevents oxidation in the brain, eyes and kidneys. It will also help support the production of SOD, catalase and glutathione;
- Bilberry extract: preserves vision and reduces oxidative damage in the eyes.
