Since the 1980s, mobile phones has transformed from an pricey item used by business people to a really popular communications device that’s used by most of the general population. in actual fact, nowadays, mobile phones outnumber land line phones in many countries.

Mobile phones started life as the two-way radio, which was also called mobile rigs. these were used in vehicles for instance taxis, police cars & ambulances, but were not strictly mobile phones as they were not usually connected to the telephone network. although the very first mobile phones were installed permanently in vehicles, later versions for instance the transportables, also called bag phones, could be carried, too, & can be used as either portable or as mobile two way radios.

The first generation of mobile telephones are often referred to as 1G. These mobile telephones are the analog devices that were introduced in the eighties and continued until they were replaced by 2G mobile telephones, which ran on digital networks. indeed, although 1G and 2G systems use digital signaling to connect the radio towers to the rest of the phone network, the voice itself during a telephone call encoded to digital signals in 2g whereas voices on 1G telephones are not.

The earliest second generation mobile phones were commercially launched in finland in 1991. While 2-g networks were totally digital, the earlier 1-g networks were analog. one of the benefits that 2-g networks had over the 1g predecessors was that conversations were digitally encrypted. This was pivitol as third parties were able to to listen in on calls on analog networks. as well as this, 2-g systems were lots more efficient, which allowed far more mobile phones to be used. Finally, 2-g introduced data services for mobile, which include sms messages.

After the launch of 2g mobile phones, the earlier mobile telephone systems were called 1g. while radio signalling on 1g networks are analog, & on 2-g networks they’re digital, both the 1g and 2g systems use digital signaling to link the radio towers & the rest of the phone network.

The first pre commercial 3g mobile phone network was launched in japan in may of 2001. 3g was later released commercially in Japan on october, 1 2001.

3g is the third generation of mobile phone standards & technology, which succeeded 2g mobile phone technology. the birth of 3g technologies enabled network operators including orange to offer their users a larger range of high-tech services. This includes broadband internet, as well as high tech video calls.

Although 3g has been very successful, there’s also been many complaints about it. These include criticism over the expense of 3g phones, a lack of network coverage because its still a relatively new service & the high power usage of 3g phones.

Following 3-g, we can look forward to the release of 4g technology, which promises to be the best and most developed mobile telephone technology to date.

Thanks for browsing our article about the birth of mobile phones. as you’ve probably guessed by now, the mobile telephone has come a long way since it was first launched and there’s a fair chance of, it’ll be developed further still.

Am I the only one just a little bit concerned about the lack of specific ideas on fixing the economy by all of the current presidential candidates? They are quick to hit all of the hot button no brainer political issues like the war in Iraq, healthcare, oil prices etc. but when it comes to talking about the economy we hear more ideals than we do ideas. Phrases such as “I will protect the middle class” or “Americans deserve to work hard and be successful” are commonplace. The question is what are you as a presidential candidate going to do in this global economy to stimulate new jobs and reduce the outsourcing of current American jobs? I believe one huge step toward these goals would be for the government to invest in the proliferation of new web technologies and in education in the web technology sector.

How would this be accomplished? Right now the U.S. government provides grants to states to prepare workers for new and emerging industries. By increasing this funding and setting aside a certain amount for web technology grants the government would provide a big boost of capital for this emerging industry. Also, the government could provide small business loans to businesses in the web technology sector to provide access to middle class Americans. Finally, by increasing funding for web technology education the government would provide a boost to the level of skilled labor in the market.

Why web technology? If we are looking to provide quality opportunities for middle class Americans this is the place to start. Startup costs for a web business are low. The web is the great equalizer in that if you have a good idea and you can create a web presence the payoff can be immense. You see it every day now that the internet is doing away with the need for newspapers, movies, even television. Advertising dollars are slowly migrating to the web. Our economy is moving there as well but unfortunately our leaders don’t have the forethought to move it out of the industrial age just yet. By making a big push in this sector the United States would gain a huge economic advantage in the global economy which would create new jobs and possible reduce the outsourcing of jobs. It is time to retrain our workforce to operate in the new web economy. Unfortunately, our current presidential candidates do not seem to find this notion politically satisfying.
