which was the very first operating system used in cell phone?

Question

which operating systems are used in cell phones and which is the oldest among them?

Answer 1

That depends! If we look at the meaning of "Operating System", then we are looking at softwate rather than hardware and software that will operate both hardware and software. Therefore, the first OS has to be very recent as older phones were hardware operated and could do nothing except work like a two way radio (which is what they really were in the beginning). The first OS I believe has to be a Symbian OS as Microsoft have only just entered the Mobile OS market and Symbian are now at V60.

Answer 2

Its Palm and Windows Mobile....... Symbian OS is ver slow...

But I should also tell you that Non-OS phones are faster then OS phones... So plz also have a look at Non-Smartphones.
and here's a mini comparison of NON-OS phones,,,

1) Interface Speed: UI of Motorola and Samsung is the fastest one, Nokia is 2nd... But SonyEricsson's Animated UI is ver slow..

2) Data Loading Speed (From Memory Card or Phone): SonyEricsson is best here. It can easily load even a fully loaded 1GB card in less then 10 Secs... Samsung Comes 2nd..

3) Java Power: Nokia is the fastest here. Nokia 5300 is the 4th fastest Java enabled phone ever.... and the fastest Non-Smartphone.. SonyEricsson is 2nd..


----------

I hope it will help u choosing the Best OS according to your need..

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.

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


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.
