History And Evolution Of Mobile Phones
Mobile phones are communication devices that enable people to connect from long distances without the help of cable or other previous forms of telephony services. Mobile phones use radio links to receive and make telephone calls. In order to work, a mobile phone operator provides the subscriber with the capability through the purchase of cellular network from them.
History of mobile phones
Radiophones have been in use for a very long time where the invention of Reginald Fessendens made way to the mobile telephony market. In the past however, the gadgets were only available to the military and were in influential during the Second World War and throughout in 1950s. However, back in June 17th 1946, it has been recorded that the first mobile telephone call was made, and the kind of service used at the time was the Bell System’s Mobile Telephone Service. From that time, on, the evolution of mobile phones continued through 1950s, mobile phones that weighed up to 40kgs were in use, and those were composed of vacuum tubes as well as relays.
The first use of cellular network
As the evolution of mobile phones ensued, back in 1973, Martin Cooper would later be recorded as the first person to use a heavy but yet portable handset to make telephone calls. This was perhaps the first time cordless telephones were getting introduced into the telephony market. Unlike the first mobile phone that weighed up to 40kgs, the Martin Cooper invention weighed about 5kgs and sold in the market at about 4,000USD. Although the phone took about 10hrs to charge, it could only last about half an hour before the battery died off while talking. By 1983 demand was higher and consumers wanted a test of this new exciting technology. The entire cellular technology went on to launch in different parts of the world throughout 1970s and 80s.

2G and 3G
The second generation of mobile phones also known as 2G took place in 1991 when this technology was launched back in Finland to work on the GSM standard networks and thus challenging the first generation also known as the 1G that had gained popularity throughout 1980s. The 2G network was not to stay on forever since 10 years after its debut; in 2001 the third generation of mobile phones also known as 3G took a course where the WCDMA standard network was employed.
Although, up until now, no major changes on the third generation of mobile phones, the fourth generation and fifth generation have already started making their way, however, there have been updates on the 3G and this move has seen different terms come in the picture with 3.5G, Turbo 3G as well as 3G+ gaining popularity. All those enhancements are done to ensure that the network increases in speed and the packet data and this terms high speed packet access also known as HSPA. The idea is to have an improvement on data transfer in terms of speed and stability as well as the capacity of data that can be handled per second.
