Stupid donkeys! Kuprijanov invented a protypical mobile phone, not a cell phone. Wait… I guess I have to retract that. Apparently the terms are basically synonymous, but I was under the impression that there was a difference for the longest time. The inventor of the Cellular phone is Henry Sampson, Jr. Sampson is an African-American from Jackson, Mississippi.
He attended Morehouse and transferred to Purdue. D from Illinois. Sampson is the first African-American to receive a Ph. D in Nuclear Engineering. Hopefully, Dr. Sampson was well rewarded for his efforts. He holds the patent for his discovery : 3,, Check it out on Google. Pass this information on.
Barbershops and Beauty Salons are great places to discuss this info. During the week, let others know about Dr. Perhaps Aradin, you can then explain why there is no reference to cell phones, radio phones or any phones for that matter in the patent you cite, nor is there any credible evidence that the gamma-electric cell is employed as a component of the cell phone infrastructure.
Instead of posting the contents of Internet Email Rumors, your time might better be spent working to better the human race by actually contributing to society rather than detracting from it. Byron, The patent number given will give you the necessary proof you are asking for. There is a way to discuss and debate without being condescending. Sampson is a brilliant man and inventor, but none of his inventions have anything to do with cell phones. I came with an invention for cell phones too.

Pay as You Go Cell Phones. Leave this field empty. With such a new service many were sceptical as the analogue systems were still in widespread use. Nevertheless by the end of GSM had attracted over a million subscribers and there were 25 roaming agreements in place. The growth continued and the next million subscribers were soon attracted. This represented a major milestone in cellular telecommunications history. Originally GSM had been planned as a European system. By adopting new frequencies new operators and further competition was introduced into the market apart from allowing additional spectrum to be used and further increasing the overall capacity.
This trend was followed in many countries, and soon the term DCS was dropped in favour of calling it GSM as it was purely the same cellular technology but operating on a different frequency band. In view of the higher frequency used the distances the signals travelled was slightly shorter but this was compensated for by additional base stations. Looking back on the way GSM developed, the way it was deployed and grew over the years, shows the GSM history is a story of success. GSM was used in many countries outside Europe.
Deployment on this scale had not been anticipated and it resulted in its name change from Groupe Special Mobile to Global System for Mobile communications. The number of subscribers grew rapidly and by the beginning of the total number of GSM subscribers reached the 1 billion mark - a major milestone in the history of cellular telecommunications as well as for GSM itself.
Attaining this figure was celebrated at the Cannes 3GSM conference held that year. Figures continued to rise, reaching and then well exceeded the 3 billion mark.
In this way the history of GSM has shown it was a major success.

Showcasing the best Our modern world is awash with ideas. Some become the raw material of great technology achievements.
Most don't. The difference in fortune usually comes down to a pivotal moment along the way. For GSM it all came down to 37 weeks in During a trial period engineers drove around the country making calls to patient volunteers to test the signal strength. They each expected to win up to 20, subscribers within ten years. To their astonishment, three years later they had over half a million subscribers, and network coverage reached 90 per cent of the population.
A strong market for mobile technology drove the development of smaller and cheaper phones until there was one to suit every pocket. It was teenagers—always cultural innovators—who developed extraordinary dexterity and OMG! No one would have been more surprised at this development than the companies who first invested in cellular mobile phone networks, thinking they might have a market among wealthy businesspeople keen to acquire the latest gadget.
Countries besides the UK and USA also developed their own networks, and calls stopped at their borders. Taking their lead from the Nordic countries, which had cooperated to develop networks, a group of European government and industry technocrats came together in to work towards a common standard. In European leaders met in Bonn to sign the agreement that would allow mobile phone users to roam from one country to another, hopping from network to network.
The common standard agreed in was called GSM. They would initially use a single radio frequency band, MHz, across Europe, ensuring that users could pick up a signal wherever they were. They would include provision for SMS short message service, or texting , and would have increased security features.
Nine out of ten people in the world today are now within reach of a terrestrial GSM network.
