Cell Phones!!!!!

The cellular a type of wireless communication that is most familiar to mobile phones users. It's called 'cellular' because the system uses many base stations to divide a service area into multiple 'cells'. Cellular calls are transferred from base station to base station as a user travels from cell to cell.

The basic concept of cellular phones began in 1947, when researchers looked at crude mobile (car) phones and realized that by using small cells (range of service area) with frequency reuse they could increase the traffic capacity of mobile phones substantially. However at that time, the technology to do so was nonexistent.

The cellulars started to be used in the Second World War to communicate the soldiers. Then it was commercialized, first in USA, and then in the rest of the world. It has become the most popular thing for communication, exept for the Internet.In my opinion everything that helps communicating people is good, it all depends in what way do you use it. I don't think that we will be like robots and all that staff, please we are humans, not dogs that do what a smarter mind says!!!!!!

Mobile Phones!

Hey! my name is Veronika and now, im going to write my opinion about mobile phones.

The cell phone is a old invent .It's a phone that you can take anywhere you go.A mobile phone need a battery, and without signal it doesn't work.You can recive calls or text mennsege, if you can't answer the calls you have a "voicemail".
A cell phone is small and it have lights .You can choose the ringtone that you like, you can also turn down the volume in case the phone goes of when you're in a meeting or in a sielence place .The price is over 150$ , but the good news is that the price will come down. Today everybody has a cell phone , so the communication can be very fast and reliable!
That is everything!!
See you soon...

Mobile Phones

The mobile phone is a short-range, portable electronic device used for mobile voice or data communication over a network of specialized base stations known as cell sites. In addition to the standard voice function of a telephone, current mobile phones may support many additional services, and accessories, such as SMS for text messaging, email, packet switching for access to the Internet, java gaming, bluetooth, infrared, camera with video recorder and MMS for sending and receiving photos and video. Most current mobile phones connect to a cellular network of base stations ,which is in turn interconnected to the public switched telephone network . Since the mid-2000s, an increasing number of cellphones can connect to the Internet, a portion of which can be navigated using cellphones.

Well in my opinion, mobile phones are very important in the life of a human being. If we didn't have mobile phones, we couldn't talk to another person who is away from you. But you can also send SMS, and take pictures, make videos, and search in the internet...

well that's my second post! i hope you read it and enjoy it!
thank you very much...
bye bye! xoxo

Mobile Phones -

Mobile Phones are a modern and portable electronic device wich has become a very popular fashion artifact. Even mobile phones started as phones, know they support many additional services, and accesories, such as SMS for text message, email, packet switching for access to the Internet, java gaming, bluetooth, infrared, camera with video recorder.

Mobile phones adquire their signal from base stations that are usually mounted on a tower, pole or building, located throughout populated areas. The phones have a low-power transceiver that transmits voice and data to the nearest cell sites, normally not more than 8 to 13 km away.

An increasing number of countries, particularly in Europe, now have more mobile phones than people. According to recent data, the European Union's in-house statistical office, Luxembourg had the highest mobile phone penetration rate at 158 mobile subscriptions per 100 people (158%), closely followed by Lithuania and Italy. In Hong Kong the penetration rate reached 139.8% of the population in July 2007.Over 50 countries have mobile phone subscription penetration rates higher than that of the population and the Western European average penetration rate was 110% in 2007. The U.S. currently has one of the lowest rates of mobile phone penetrations in the industrialized world at 85%.
There are over five hundred million active mobile phone accounts in China, as of 2007, but the total penetration rate there still stands below 50%.

Warnings about cell phones!

Studies from the Institute of Cancer Research, National Cancer Institute and researchers at the Danish Institute of Cancer Epidemiology in Copenhagen for example showed no link between mobile phone use and cancer.

The use of mobile phones by people who are driving has become increasingly common, either as part of their job, as in the case of delivery drivers who are calling a client, or by commuters who are chatting with a friend. While many drivers have embraced the convenience of using their cellphone while driving, some jurisdictions have made the practice against the law, such as the Canadian provinces of Quebec and Newfoundland and Labrador. Officials from these jurisdictions argue that using a mobile phone while driving is an impediment to vehicle operation that can increase the risk of road traffic accidents.

Men who use mobile phones on a regular basis lose about 30 percent of their active sperm cells. Those who carry their mobile phones in pockets of their pants are putting their potency at great danger. Scientists say that even in sleep mode mobile phones are harmful.[

Mobile Phones

At the beginning, two-way radios were used in vehicles such as taxicabs, police cruisers, ambulances, and the like, but were not mobile phones because they were not normally connected to the telephone network. Users could not dial phone numbers from their mobile radios in their vehicles. A large community of mobile radio users, known as the mobileers, popularized the technology that would eventually give way to the mobile phone. Originally, mobile phones were permanently installed in vehicles, but later versions such as the so-called transportables or "bag phones" were equipped with a cigarette lighter plug so that they could also be carried, and thus could be used as either mobile or as portable two-way radios. During the early 1940s, Motorola developed a backpacked two-way radio, the Walkie-Talkie and later developed 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.

If we keep going on with this sutuation there's going to be a moment were everything is going to be technological and we are going to depend on the mobile phones and that's not good because we won't pay attention to the things that really important.
