Mobile technology through the generations From 1G to 4G

Technology has penetrated into our daily lives, and made itself indispensable for us. Broadband has gone mobile now, and the 4G technology boosts its powers. Fourth generation cell phones enable wireless mobile communications at a much faster speed than the earlier generations. Let’s trace back the history of wireless communications to know how far mobile technology has progressed.

The history of wireless generations

 4G couldn’t have literally landed itself on us, if there had been no 3G, 2G or 1G. The history reveals the path that wireless technology took, to arrive at the present situation.

1.      First generation or simply G – Cell phones came into the forefront in the 1970s. The 1G cell phones only allowed voice communication. It picked up analog signals from the handset and transmitted them to the radio towers. The signals were then passed through the telephones. There weren’t any set standards for wireless communication at the time.

2.      Second generation or 2G – In 1991, the analog signals were successfully replaced by digital signal processing system, which was first introduced in Finland. It enabled radio communications and secured voice applications. It also made data exchange possible in the form of text messages. The Short Message Service (SMS) was a boon of improved mobile technology, which gained popularity worldwide.

3.      Third generation or 3G – The 3G mobile system allowed high quality voice channels, as well as limited data transmission through broadband. The third generation tried to eliminate the earlier deficiencies. It came into action in the 2000s and strived to craft a global communication system. Video calling was an added feature along with Internet access through smart phones and laptops.

4.      Fourth generation or 4G – It is the most hip and the happening one amongst technology for cell phones. It promises high speed data transfers, in mobile as well as immobile positions, from anywhere and at anytime. The latest technology tries to ascertain seamless service with broader bandwidth at a higher data rate. Besides, the set guidelines also promise benefits like simultaneous user access through cell phones, smooth transmission, and facility to change networks without any interruption.

The specific standards for the 4G technology have been set forth in the later part of 2010. However, though the networks for cell phones are trying to comply with all the specifications, it is still a vision.
