“Form follows you”
A personal mobile communication device which lets you be free and fun. It is light, simple and carefree. You can change its form according to your needs during the day.
*target
It is targeted to the young consumers who are likely to be active and take place in a lot of different activities.
*why this target ?
Because they move and change place too much. They do a lot of different things during the day. So that’s what my design offers : to adjust to the moment, the place and the function.
*technologies that are used
It uses liquid battery, speech recognition, flexible touch screen, touch sensitive body cover which lets it understand and adjust to the environment. It has a simple programmable body mechanism so that it changes forms in different situations.
*the functionality of design
You dont have to carry it in your pocket or on your wrist. You can carry it anywhere, in anyform. You can roll it, bend it, put on your clothes like a clip. It also makes some form changes that makes it more ergonomical: i.e. when you want to talk on the phone, the body form turns into the form of the good old telephone. You can personalize these forms and record them. So it fits you the best in the way that you have chosen. The functions that it has also create a feeling of electronical pet, as it senses your moves, understand what you want, respond you in the best way. It learns you, to fit you better.Also e-motions lets you send forms to the other 888 users. It could be the shape of a heart or a small dance. This way you can talk without words.
*how the user interacts
E-motions… It means electronical motions that 888 has. You can send and receive forms from / to friends. You can send a heart shape to your girlfriend, so her telephone turns into an icon of heart. Or you can send a dancing form to your friends to call them to the party tonight. This is the fun side of the product. If we look from the functionality side, 888 is quite flexible. You can put it into your pocket, roll it and make it smaller, or put on your wrist when you want to make a video call on the go. If you want to talk like a normal telephone, there you have your telephone shape. We go through a lot of places and situations in the daily life, so it seems like one form is not enough.
*what is unique ?
You can change the form of the body. Not just the color. And you can do the same by sending an e-motion to your friend.
*the inspiration
The idea is that “the perfect form” does not exist. “Form follows you”
We create the perfect form for each function.

Cellular concepts
01:09 AM
ramesh ahir
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.
In all these early examples, a mobile phone had to stay within the coverage area serviced by one base station throughout the phone call, i.e. there was no continuity of service as the phones moved through several cell areas. The concepts of frequency reuse and handoff, as well as a number of other concepts that formed the basis of modern cell phone technology, were described in the 1970s. In 1970 Amos E. Joel, Jr., a Bell Labs engineer,[4] invented an automatic "call handoff" system to allow mobile phones to move through several cell areas during a single conversation without interruption.
In December 1971, AT&T submitted a proposal for cellular service to the Federal Communications Commission (FCC). After years of hearings, the FCC approved the proposal in 1982 for Advanced Mobile Phone System (AMPS) and allocated frequencies in the 824–894 MHz band.[5] Analog AMPS was eventually superseded by Digital AMPS in 1990.
A cellular telephone switching plan was described by Fluhr and Nussbaum in 1973,[6] and a cellular telephone data signaling system was described in 1977 by Hachenburg et al.[7] In 1979 a U.S. Patent 4,152,647 was issued to Charles A. Gladden and Martin H. Parelman, of Las Vegas for an emergency cellular system for rapid deployment in areas where there was no cellular service.

History of mobile phones
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.
However it was the 1940s onwards that saw the seeds of technological development which would eventually produce the mobile phone that we know today. Motorola developed a backpacked two-way radio, the Walkie-Talkie and a large hand-held two-way radio for the US military. This battery powered "Handie-Talkie" (HT) was about the size of a man's forearm. In 1946 in St. Louis, the Mobile Telephone Service was introduced. Only three radio channels were available, and call set-up required manual operation by a mobile operator. Also that year, Soviet engineers G. Shapiro and I. Zaharchenko successfully tested their version of a radio mobile phone mounted inside a car. This device could connect to local telephone network with a range of up to 20 kilometers.[citation needed]
Top of cellular telephone towerDuring the 1950s the experiments of the pioneers started to appear as usable services across society, both commercially and culturally. In the 1954 movie Sabrina, the businessman Linus Larrabee (played by Humphrey Bogart) makes a call from the phone in the back of his limousine. In 1957 a young Soviet radio engineer Leonid Kupriyanovich from Moscow created a portable mobile phone, and named it the LK-1 after himself.[1] This mobile phone consisted of a relatively small handset equipped with an antenna and rotary dial, and communicated with a base station. The LK-1 weighed 3 kilograms and could operate in a range of up to 20 or 30 kilometers. The battery lasted 20 to 30 hours. The LK-1 was depicted in popular Soviet magazines as Nauka i zhizn. Kupriyanovich patented his mobile phone in the same year. The base station serving the LK-1 (called ATR, or Automated Telephone Radiostation) could connect to local telephone network and serve several customers. During 1958, Kupriyanovich produced a "pocket" version. The weight of improved lighter handset was about 500 grams.
In 1964 Improved Mobile Telephone Service was introduced with additional channels and more automatic handling of calls to the public switched telephone network. Even the addition of radio channels in three bands was insufficient to meet demand for vehicle-mounted mobile radio systems.
In 1969, a patent for a wireless phone using an acoustic coupler for incoming calls was issued in US Patent Number 3,449,750 to George Sweigert of Euclid, Ohio on June 10, 1969, but did not include dialing a number for outgoing calls.

Pioneers of radio telephony
In Europe, radio telephony was first used on the first-class passenger trains between Berlin and Hamburg in 1926. At the same time, radio telephony was introduced on passenger airplanes for air traffic security. Later radio telephony was introduced on a large scale in German tanks during the Second World War. After the war German police in the British zone of occupation first used surplus tank telephony equipment to run radio patrol cars.[citation needed] In all of these cases the service was confined to specialists that were trained to use the equipment. In the early 1950s ships on the Rhine were among the first to use radio telephony with an untrained end customer as a user.However it was the 1940s onwards that saw the seeds of technological development which would eventually produce the mobile phone that we know today.
