The capability to communicate with people has evolved notably as the mobile wireless industry has started its technology creation, revolution, and evolution since the early 1970s. It all started with 0G with the invention of the wireless telephone, which became available after the World War-II. 0G is used to refer to pre-cellular mobile telephone technology in the 1970s.
Then, 1G became the first generation wireless telephone technology with the invention of mobile phones. These were analog cell phones that were introduced in the 1990s. A decade later, the second generation of wireless mobile phones known as 2G came into the picture. Services such as text message, picture messages, and MMS were introduced with better security for both the sender and the receiver. The third generation of mobile phone technology, 3G, was introduced later in 2001. Network operators were able to offer users more advanced services while achieving greater network capacity such as video calls, cellular data, and GPS.
Since 2008, 4G has been around and it’s all about high-speed data transfer with peak download speeds of 100 Mbps and uploads at the rate of up to 50 Mbps – enabling the mobile television running at a higher resolution. With all the innovation and evolution of this technology in the past decades, the world is now looking at 5G that is bound to be the next breakthrough in the coming years.
