4G made mobile internet speeds up to 500 times faster than 3G and allowed support for HD TV on mobile, high–quality video calls, and fast mobile browsing. With 50 billion expected devices to be in use by the end of 2020, and 70% of IoT applications used for Business to Business operations, 5G paves the way to a new era of remote computing. As compared to 4G, 5G will have 10x less latency, 50x more speed and 1000x more capacity, for a larger number of connected devices. We will also see 90% less energy used per bit of data, which will have a huge impact on battery life for mobile devices.
5G is widely believed to be smarter, faster and more efficient than 4G. It promises mobile data speeds that outperform the fastest home broadband network currently available to consumers. Low latency is a key differentiation between 4G and 5G. Latency is the time that passes from the moment information is sent from a device until it can be used by the receiver. Reduced latency means that you’d be able to use your mobile device connection as a replacement for your cable modem and Wi-Fi. You’d also be able to watch a 4K video almost straight away without having to experience any buffering time.
5G also uses a new digital technology called Massive MIMO, which stands for “multiple input multiple output”, that uses multiple targeted beams to spotlight and follow users around a cell site, improving coverage, speed and capacity. Current network technologies operate like floodlights, illuminating an area but with lots of wastage of the light/signal. Part of the roll-out of 5G involves installing Massive MIMO and 5G New Radio to all mobile network base stations on top of the existing 4G infrastructure. It uses a 5G New Radio interface, along with other new technologies, that utilizes much higher radio frequencies (28ghz as compared to 700mhz - 2500mhz for 4G).
As 5G becomes widely adopted, we will see progress in areas that use real-time communication, such as: · Autonomous Vehicles
· Cloud & Virtual Reality Gaming
· Industrial Control Systems
· Immersive Entertainment
· Instant Movie Streaming
· Internet of Context
· Remote Healthcare
· Smart Cities
· Smart Factories
· Smart Grid
· Smart Homes
· Smart Agriculture
