Since the 1980s, mobile phones has transformed from an costly item used by business types to a really popular communications device that’s used by much of the population. in actual fact, these days, mobile phones outnumber land-line telephones in plenty countries.
Mobile phones were born whena number of users of mobile radio, known as the mobileers, popularised the use of mobile phone technology. Mobile phones were originally installed in vehicles permanently, but later versions of the radio, which were named transportables, could also be carried, which meant that they could be used as a mobile or as moveable two-way radio. during the early 1940s, Motorola developed a two-way radio in a rucksack, the walkie-talkie, and this was widely regarded as one of the first mobiles.
The first generation of mobile telephones are often referred to as 1G. These mobile telephones are the analog items that were introduced in the 1980s and continued until being replaced by 2G mobile telephones, which ran on digital networks. in fact, even though 1G and 2G systems use digital signaling to connect the radio towers to the phone network, the voice during a phone call encoded to digital signalling in 2g while voices on 1G telephones aren’t.
Second generation (2-g) mobile phones first appeared in the nineties. Unlike 1g phones that were analog, 2-g phones use digital signals to provide voice services and for sms text messaging and wap.
A number of the advantages of 2g phones are that they use lower powered radio signals, which need less battery power. This means that phones last longer between charges, so batteries – and therefore the telephones themselves – can be made tinier. as well as this, 2g phones offer more privacy. Indeed, digital phone calls are a lot harder to eavesdrop on than 1-g phone calls.
The term 2.5G is used to describe the phone technology that is post 2-g, but not quite 3g. However, while the terms 2-g and 3g are officially defined, the term 2.5G is not. in actual fact, this term was invented for marketing only.
The first pre-commercial 3-g mobile phone network was launched in japan in may 2001. 3-g was later commercially released in Japan on october, 1 2001.
3-g is the third generation of mobile phone standards and technology, which is the successor to 2g technology. the arrival of 3g technologies enabled network operators including orange to give their users a wider range of more advanced services. This includes wireless internet, in addition to high-tech video calls.
Despite the success of 3g, there’s also been some complaints about it. These include criticism over the expense of 3-g phones, a lack of network coverage because it’s still a relatively new service and the amount of power that 3g phones use.
After 3g, we can look forward to the birth of 4g technology, which promises to be the finest & most sophisticated mobile telephone technology to date.
Thank you for reading our article about the invention of mobile phones. as you’ve probably guessed by now, the mobile telephone has come a long way since it was initially launched & chances are, it will be developed even further.
