Let’s Talk About The Evolution Of Mobile Phone Technology | Bega District News


way of life,

2G, or not 2G: that is the question: is it more worthy of the mind or to suffer thanks to 5G. Unlike poor Hamlet, I haven’t lost my mind, but there is a lot of confusion with the different ‘G’ levels cited by telecom providers, and to confuse us even more, Huawei has announced that they are looking for the 6G. I thought it was worth giving a very brief overview of the different generations of mobile phone technology to better understand how 5G fits into our landscape. Australia had a very early “007” mobile service which was launched in August 1981. It is often referred to as 0G because it was not a true cellular mobile system. It operated in the 500 MHz band and was shut down in 1993. Mobile phone technology came of age in February 1987 when the Analog Cellular System (AMPS) was introduced with cell phones. This system is generally referred to as 1G and was a true cellular system with frequency reuse. It operated in the 850MHz range. This network was closed in 2000. At the time of the arrival of 2G in 1993, less than 4% of the Australian population had an analog mobile. 2G has stepped up security and, after sending the first text message the previous year, introduced Australians to texting. 2G was commonly referred to as GSM, but some countries (including Australia) also had CDMA to provide additional coverage. CDMA lived a short life – 1999 to 2008. 2G typically operated around the 900MHz range and later the 1800MHz band. 2G also introduced data with GPRS and EDGE at theoretical maximum speeds of 0.384 Mb / s. 2G was largely shut down in 2016. 3G was introduced in 2003 and saw the advent of mobile broadband with significantly better data speeds, up to 7.2 Mb / s. 3G operated in the 850MHz and 2100MHz ranges. My guess is that 3G will be completely shut down in Australia by 2023. 4G started in Australia in 2014. Why? Three reasons. Speed, speed and speed. With greater data demands from users of smartphones and other mobile devices, the network had to respond. 4G has theoretical maximum speeds of up to 1000 Mb / s. To give you an idea of ​​the workload imposed on modern operators, in a month, Telstra alone connects 500 million calls, sends 50 million calls. SMS and carries 50 petabytes of data. 4G operates on a number of frequencies ranging from 700 MHz to 2600 MHz. Which brings us to 5G. Recently introduced in Australia, it is currently only available in ten cities. The demand for 5G is not only driven by the need for speed, but also by the need to be connected to everything. 5G will have a theoretical speed of 10,000 Mb / s but, above all, it will have reduced latency (more than five times better than 4G) and will allow significantly more simultaneous connections. The combination opens up a whole new world of Internet of Things (IoT) devices that will explode in the market. 5G will initially operate in the 3,500 MHz frequency range, but in years to come it will operate up to 28,000 MHz (28 GHz). That’s significantly higher than any other generation of mobile technology, but radio waves are non-ionizing waves, and forty-six years after Dr. Martin Cooper made the first phone call from a mobile, we still haven’t seen any negative health effects. radiation caused by mobiles.
