Martin Cooper invented the cell (mobile) phone. He was the first one to make a call and speak on his moble phone. Mr Cooper, born December 26, 1928, wanted people to be able to carry their phones with them anywhere. While he was a project manager at Motorola in 1973, Cooper set up a base station …in New York with the first working prototype of a cellular telephone, the Motorola Dyna-Tac. After some initial testing in Washington for the F.C.C., Mr. Cooper and Motorola took the phone technology to New York to show the public. The First Cellphone (1973) Name: Motorola Dyna-Tac Size: 9 x 5 x 1.75 inches Weight: 2.5 pounds Display: None Number of Circuit Boards: 30 Talk time: 35 minutes Recharge Time: 10 hours Features: Talk, listen, dial See related links for further information on Martin Cooper and his invention. The idea of the cell phone began in the 1920's with police radios, but it wasn't until 1947 that the first one was made by Bell labs. In 1974 Dr. Martin Cooper is given credit for the cell phone that is most like the ones we have today. He was working for Motorola at the time. The phone was only for government use and in 1984 it was sold to the public for the first time. The early cell phones were large, heavy, and copied land line phones in style. They were carried in a zippered bag with the whole bottom as the battery. The cell phone was first thought of in the 1920's when the use of police radios began. In 1947 Bell Labs made the first cell phone, but it took Dr. Cooper of Motorola to make a cell phone in 1974 for the government. The public use of cell phones began in 1984. Your question has two answers. The phone was invented in 1889 by Bell. The cell phone idea began in the 1930's, but in 1947 Bell Labs made a cell type phone. The first cell phone inventor id given to Dr. Martin Cooper of Motorola in 1974. This phone was sold to the government. The public did not get it until 1984. It was made by Bell labs in 1947, but the man given the most credit for it is Dr. Martin Cooper who made one very much like what we have today in 1973. We knew someday everybody would have one. Martin Cooper created the "DynaTAC," the first commercial cell phone, which hitthe market in 1983. (CNN) -- In 1973, Martin Cooper changedthe world, although he didn't know it yet. With the invention therewas concern regarding brain cancer due to the fact that cell phonessend out high frequency of radio waves. It was invented by Will Maacmillan in 1969 ÂDoctor Martin Cooper invented the modern cell phone. He invented the technology responsible for the cell phone when was the Director of Research and Development at Motorola. Cooper is also known as the first person to make a call on a cell phone. His groundbreaking call took place in April of 1973 in New York. He is currently the CEO of an antenna corporation.. (MORE)
Dr Martin Cooper, a former general manager for the systems division at Motorola, is considered the inventor of the first portable handset and the first person to make a call on a portable cell phone in April 1973. The first call he made was to his rival, Joel Engel, Bell Labs head of research.. AT&…T's research arm, Bell Laboratories, introduced the idea of cellular communications in 1947. But Motorola and Bell Labs in the sixties and early seventies were in a race to incorporate the technology into portable devices.. Cooper, now 70, wanted people to be able to carry their phones with them anywhere.. While he was a project manager at Motorola in 1973, Cooper set up a base station in New York with the first working prototype of a cellular telephone, the Motorola Dyna-Tac. After some initial testing in Washington for the F.C.C., Mr. Cooper and Motorola took the phone technology to New York to show the public.. In 1973, when the company installed the base station to handle the first public demonstration of a phone call over the cellular network, Motorola was trying to persuade the Federal Communications Commission to allocate frequency space to private companies for use in the emerging technology of cellular communications. After some initial testing in Washington for the F.C.C., Mr. Cooper and Motorola took the phone technology to New York to show the public.. On April 3, 1973, standing on a street near the Manhattan Hilton, Mr. Cooper decided to attempt a private call before going to a press conference upstairs in the hotel. He picked up the 2-pound Motorola handset called the Dyna-Tac and pushed the "off hook" button.. The phone came alive, connecting Mr. Cooper with the base station on the roof of the Burlington Consolidated Tower (now the Alliance Capital Building) and into the land-line system. To the bewilderment of some passers-by, he dialed the number and held the phone to his ear.. Who is he? Cooper grew up in Chicago and earned a degree in electrical engineering at the Illinois Institute of Technology. After four years in the navy serving on destroyers and a submarine, he worked for a year at a telecommunications company.. Hired by Motorola in 1954, Mr. Cooper worked on developing portable products, including the first portable handheld police radios, made for the Chicago police department in 1967. He then led Motorola's cellular research.. (MORE)
I'm guessing in the 1900's I'm not sure of the exact year but i think it is in the 1900's. --melissa Hmmm.. pretty safe there Melissa. The first generation cellular system (1G) was set up in 1979 in Tokyo. AT&T got FCC approval for a cellular system in 1982. Car phones had been in use for a wh…ile before this, but needed a central operator and base station. It needed modern electronics and computers, to handle the automatic switching between cells.

The cell phone was invented so that people could keep in contact with each other when they do not have access to a land line phone.
The idea of cell phones dates to the 1920's and police radios. The first cell phone was made by Bell labs in 1947, but it wasn't until 1974 when Dr. Cooper of Motorola made the first cell phone we would call a cell phone for the government. In 1984 the first cell phone was sold to the public.
They are very good in emergencies if you need to contact someone, but too much of it can hurt you because of radioactivity.
It was made for government use.The first cell phone was made by Bell labs in 1947, but Dr. Martin Cooper of Motorola is given the most credit for the invention of the cell phone in 1974.

The cell phone idea actually started in the 1920's with police radios and then in 1947 Bell labs made a cell type phone. It was in 1973 that Dr. Martin Cooper made the first cell phone like the ones we have today.
People say to make life easier. I say because he hated to stop what he was doing just to make a call. That is why he invented the first Cell Phone. he was part of the team of the first cell phone but yeah he did hate to stop what he was doing just for a call but he invented the first cell phone cz …they were struggling to get things done.

The idea of cell phones began in the 1920's with police radios, butthe first one was invented in 1948 by Bell Labs. The cell phone weknow today was invented by Dr. Martin Cooper of Motorola in 1974and was only used by government until 1984 when they were firstsold to the public. The first cell phone…s were large, heavy, andexpensive to use. Many were in a bag and looked like a house phonebut the entire bottom was a battery. Who invented the first "modern cell phone" as we know it? Dr.MartinCooper ( director of R&D Motorola USA) is credited with"inventing" one in 1973 along with his research team, and fundingfrom the US government. So the first cell phone company wastechnically Motorola USA although technological ground work laid byothers, AT&T, Bell Labs, US military, etc. was obviously usedto make it all work. Martin cooper was born in Chicago in 1928 andgraduated from IIT in Electrical Engineering. In 1954 he was hiredby the Motorola Company( that's in the USA). The first "mobile phone" was in Sweden by Lars MagnusEricsson (May 5, 1846 - December 17, 1926) A very common namein cell phones today. The first cell phone was made by Bell labs in 1947, but Dr. Martin Cooper of Motorola is given the most credit for the invention of the cell phone in 1974. The first cell phones were only sold to the government and in 1984 they finally were offered to the public. They were large, heavy, and copied land line phones in style and were carried in a zippered bag with the battery taking up the whole bottom. Martin Cooper ( inventor of the cell phone) added, "As I walked down the street while talking on the phone, sophisticated New Yorkers," ( in new york)" gaped at the sight of someone actually moving around while making a phone call. Remember that in 1973, there weren't cordless telephones, let alone cellular phones. I made numerous calls, including one where I crossed the street while talking to a New York radio reporter - probably one of the more dangerous things I have ever done in my life." the phone call was made in new york on April 3, 1973. The first fully automatic mobile phone system, called MTA, was developed by Ericsson and commercially released in Sweden in 1956. This system had cells, but the phones could not move from one cell to the other without having to end the call. In 1970, an engineer at AT&T's Bell Labs, an American company, invented a method to allow cell phones to move from one cell to another during a call; called a "call hand-off." The first truly successful cellular network was the ARP, introduced in Finland in 1971. It is viewed as a 0G (zero G) network which had very good coverage and achieved great popularity. All the phones used in the previously mentioned networks were large in size, not suitable for being held by hand. They were mostly applied in automobiles, with the main device installed in the trunk of the car, attached by wire to a handset near the driver seat. The first practical hand-held cell phone was invented by Motorola, an American company, in 1973. Dr. Martin Cooper, an American born in Chicago, is the inventor listed on the US patent that was used to register that device. (MORE)
Bell labs made a first cell phone in 1947, but Dr. Martin Cooper in 1973 made a cell phone most like we have today.
a digital cell phone gives you better coverage, sound quality, and features. Like Verizon for instance, their txt messaging and VCAST services are all digital
Dr. Martin Cooper is the person credited with both inventing themodern cell phone. He also made the first cell phone call in NewYork City, New York in April 1973.

Motorola began developing the RAZR (as it is properly known) in July 2003, with it being released for sale to the public the following year.
\nAccording to the inventor, Martin Cooper, Capt. Kirk (Star Trek) talking through his "communicator" inspired him to invent the mobile phone.
The cell phone was first thought of as far back as 1930. In 1947 Bell Labs made a cell phone, but it was only a prototype.

we would live happily ever after! jk We would do what we did before cell phones and that was use a pay phone or find a land line to use.
Nope. It was a white guy. Martin Cooper in 1973. Nor did a black man invent the air conditioner, peanut butter, ice cream, traffic light, and a host of other poorly researched self esteem building myths that pop up in schools and local news pieces every February!
I am not sure who invented the phone charger First but In the year2000, Wen-Chin Yang applied for a patent for a mobile phone batterycharger. After few years a company able to create a portable phonecharger. Apart from that recently Eesha Khare named guy inventedcharger that charge the phone in 20 s…econds. However now there aremany stores like "Amazon" selling normal phone charger. (MORE)
There is no single date or single inventor. If one must be named, it would be Reginald Fessenden, who on 23 December 1900, transmitted the first voice over radio. All radio voice transmission development rises from this event.

Well it looked like a basic home phone and bigger then a moderen day cell.
no,cell-phone was invented in 1973 by a man named Martin Cooper while he was working for Moto co.
lol, . The First Mobile Phone (Cell Phone) was Invetnted In China By the Dvd SEllers . aka tony
The telephone was invented by Alexander Bell and the cell phone was created by Martin Cooper
the cell phone impacted the schools more because the school got the most cell-phone tooken away. also the parents because they get stuck with the bill and teens buy ringtones and games on there phone.
To make it easy... its the screen on top of the LCD part of a touch screen phone... so its kind of an LCD protector.

No, computers were not invented before cell phones. The firstcell phone was invented in the year of 1973 by a man named MartinCooper in Manhattan. The first computer was invented in 1939 byGerman engineer Konrad Zuse.
Advances in technology enabled manufacturers to reduce the size, increase the battery life, increase the range and add more functions to the basic design.
In 2009, Samsung released the world's first solar-powered cellphone. It was known as the Samsung Guru E1107 and featured a solarcell built into its back plate. When exposed to sunlight, the cellgenerated electricity which in turn recharged the phone's battery.The small solar cell could not provide a… lot of power, however. Togenerate the charge needed for a 5- to 10-minute voice call, thephone had to absorb an hour's worth of solar energy. Still, thesolar charging feature made sense given the markets the phone wasaimed at. The handset was designed for consumers living indeveloping markets and areas where power outages were a frequentoccurrence. Later in 2009, the company released the Samsung Blue Earth, whichalso featured a solar cell on its back - an hour of sunlight wasconverted into 10 additional minutes of talk time. Unlike the Guru,the Samsung Blue Earth offered a handful of advanced features, suchas access to the web, YouTube, and social networks. It couldconnect to the internet over Wi-Fi or 3G, while a GPS radio enabledlocation services. Marketed as an eco-friendly product, the phonewas built of recycled materials and came in a recycled cardboardbox that doubled as a stand. (MORE)

If you are talking in the field of telecommunications, then that would be a telephone by Alexander Graham Bell.
if cells weren't invented then we wouldn't be callin people whenevr we wanted.We would have to what til we got to a pay phone or a house.So life would be the same and we as people wouldn't be so lazy,so lose your phone.

Actually you are entirely wrong. the inventor is Dr. Martin Cooper (Motorola 1973) idealized by rival Joel Engal (1947). Both are white. Often inventions claimed by African Americans are sensationalized.
i cant belive u just asked that OMG!!!! well itis important b/c you can comunicate with people and well like half of my social life is on my phone .that might not b da answer u were looking 4 but dats ok LUV YA BYE and of corse emergancies. bye chika... or boy(?)
When you speak into a cellphone an analog to digital converter chip converts your voices sound waves into a digital signal. Then a digital signal processor compresses the digital signal. The compressed digital signal is then transmitted as a radio wave through the cellular network. The digital signa…l processor on the receiving end, decompresses the incoming message, an amplifier boosts the signal to make it loud. Then its passed to the speaker. The end............ DJ (MORE)
because when they had the first landlines they needed something that you could easily take out of the house so they made it Just thought I'd add a little thing I saw on TV the other day. The guy that actually invented cell phones was originally inspired as a kid. He was a Star Trek fan and thought… the little hand held communicaters on the show were terrific. He dreamed of one day making a hand held communicator just like those. So, he started with the bag phones, on to brick phones and after awhile he teamed up with some other techs and eventually techs everywhere were trying to make them smaller and more functional. I just thought it was cool that the original guy saw something on TV and decided to make it his life's work. (MORE)
Well i think that they were created for communication with people in different parts of the world.
Do you want to own a cell phone or create and own phone? If it is both then there is a lot of development that goes into a cell phone. You could DESIGN an phone and submit it to a manufacturer for production (that is not really inventing ). If you have a really good idea that has never been done be…fore try to patent it or at least register the idea before you show it to anybody. (MORE)
The cell phone was a very important invention because of its convenience and the extension of innovation and technology it spurred. Cell phones proves that our technology's transformations are exponential (meaning that the rate of change cannot be evenly measured for a long amount of time). A gre…at example of this is the car phone in the 1970s (one of the first "mobile" phones that were marketed for its convenience) to the iphones that we have in a short period of 40 years. The beginning mobile phones that were created and sold were basically bricks (meaning its size and weight was fairly inconvenient). Because of the cellphone and many other various technologies, studies are being extended such as nanotechnology and better marketing techniques, due to high demand of better phones. Another reason is quite a common one on why the cell phone is important; the growing rates of ways to communicate with each other. Psychologytoday.com proves that humans naturally have the need to have social interaction with other people. But unforturnately, the increasing rate of social media and cell phones are argued to cut off social skills in children of this generation.
