History of mobile phones and the first mobile phone

The mere presence of a mobile phone can make the meeting between two strangers more stilted, according to new research published in the May issue of the Journal of Social and Personal Relationships. Cellphones don’t disrupt casual conversation much, the study found, but when people were asked to discuss something meaningful, they reported less trust, empathy and lower relationship quality when a cellphone was in the room. Przybylski got the inspiration for the study after noticing daters and bar-goers in Manhattan leaving their phones out on the bar or table. He wondered how the phone’s presence might be influencing face-to-face interactions. He and his University of Essex colleague Netta Weinstein designed two simple experiments in which two strangers were told to talk for 10 minutes. In the first scenario, 74 undergraduates were paired up and asked to talk about an interesting event in the last month. Some of them happened to have this conversation in a room with a mobile phone sitting unobtrusively on a nearby table.

The world before smartphones was cold and unforgiving. People waited in lines for minutes on end without entertainment. Jokes aside, smartphones have irrevocably changed our lives.

The possible connection between cellphones and cancer is controversial. Many years’ worth of studies on cellphones and cancer have yielded conflicting results. Currently, there’s no consensus about the degree of cancer risk — if any — posed by cellphone use. The primary concern with cellphones and cancer seems to be the development of brain tumors associated with cellphone use.

Some research suggests a slight increase in the rate of brain tumors since the s, but cellphones weren’t in use during the s. Instead, the subtle increases are more likely related to other factors — such as increased access to medical care and improvements in diagnostic imaging. After evaluating several studies on the possibility of a connection between cellphones and glioma and a noncancerous brain tumor known as acoustic neuroma, members of the International Agency for Research on Cancer — part of the World Health Organization — agreed that there’s limited evidence that cellphone radiation is a cancer-causing agent carcinogenic.

In fact, you can get your spleen removed and continue living a normal existence, but the same cannot be said of a cell phone. Without it, you cannot expect to have a job, a consistent network of friends or a GPS guiding you to your destination, not to mention porn on-the-go. I’ve been crossing borders too frequently to hold on to friends, and sleeping anywhere that offered a free bed or a bit of floorspace so I didn’t have to work.

It’s what has allowed me to conduct this experiment. Soon I will make my reentry into the world as a real human being and, though somewhat reluctantly, purchase a phone again. In the same way that one can only see the lily pads in a Monet painting clearly when standing far away, distance from a cell phone has allowed me to observe its role in our lives with more clarity than is possible for those who are pressed right up against the blurry brushstrokes.

The first digital cell phones were the second generation 2G of cellular technology. Digital phones use the same radio technology as analog phones, but they use it differently. Analog systems don’t fully use the signal between the phone and the cellular network — analog signals can’t be compressed and manipulated as easily as true digital signals. This is why cable companies switched to digital — to fit more channels within a given bandwidth.

Digital phones convert your voice into binary information 1s and 0s and then compress it see How Analog-Digital Recording Works for details on the conversion process. This compression allows between three and 10 digital cell phone calls to occupy the space of a single analog call. FSK uses two frequencies, one for 1s and the other for 0s, alternating rapidly between the two to send digital information between the cell tower and the phone.

Clever modulation and encoding schemes are required to convert the analog information to digital, compress it and convert it back again while maintaining an acceptable level of voice quality. All of this means that digital cell phones have to contain a lot of processing power. Another decade passed before the first mobile phone made it into consumer hands. It weighed 2. Prev NEXT.
