Today’s mobile users want faster data speeds and more reliable service. The next generation of wireless networks—5G—promises to deliver that, and much more. 5G is short for “fifth generation of cellular network technology But users will know it as one of the fastest, most robust technologies the world has ever seen. To understand 5G, it’s helpful to understand what came before it. Broadly, the first generation of mobile technology, 1G, was about voice. The ability to use a phone in a car, or anywhere else, really took root here. The advent of 2G introduced a short-messaging layer—pieces of which can still be seen in today’s texting features. The move to 3G provided the essential network speeds for smartphones. And 4G, with its blazing data-transfer rates, gave rise to many of the connected devices and services that we rely on and enjoy today.


The Pathway to 5G is built upon familiar technologies such as 4G LTE and new arrivals such as Gigabit-Class LTE and Private LTE. 5G will start making appearances in cities around the U.S. in 2019 ,with much more comprehensive rollouts expected in 2020. Between 2019 and 2020, some 5G networks will initially operate in a high-frequency band of the wireless spectrum between 28 GHz and 38 GHz — also known as the millimeter wave (mmWave) spectrum.Unlike LTE, 5G operates on three different spectrum bands. While this may not seem important, it will have a dramatic effect on your everyday use. 5G represents a massive upscale of network technology. It’s a collection of ground rules for defining a network, including the radio frequencies that network will use and the ways various pieces of hardware handle data. The basic idea is that 5G, once fully implemented, will allow for much faster mobile networks and shorter lags between a request for data and its delivery. but at its best, 5G should be orders of magnitude faster than current networks. For many people, their phone may soon offer a much faster connection than their home networks. furthermore, It will provide data transfer rates many times faster than a blink of an eye, high bandwidth and greater opportunities for connectivity and reliability.
