5th Generation wireless communication technology (5G) is a revolutionary step change in the field of mobile networks. 5G is an advancement in the existing 4G system that is intended to address the growing demands of data-hungry applications requiring higher transmission speeds, extremely low latencies and better reliability. Unlike the voice and mobile broadband focus of the previous generation, 5G is a unifying communications framework that incorporates enhanced mobile broadband, massive machine-type communication and ultra-reliable low-latency communication, enabling new digital services and communication capabilities that go far beyond the capabilities of previous networks. Key underlying technologies driving 5G include the use of higher frequency bands (specifically millimeter-wave or mm Wave bands) to provide huge amounts of bandwidth that is necessary to support multi-gigabit data rates. These higher frequencies will likely lead to a reduced coverage area, the radio signals will be attenuated by objects. Massive Multiple Input Multiple Output (Massive MIMO) which increases the efficiency and capacity of wireless networks through the use of large arrays of antennas at the base station and beamforming that strengthens and focuses the signal strength toward specific user by directing it, are implemented in 5G networks to address the limitations posed by the higher frequency spectrum. The benefits of 5G networks include massive increase in speed that may go up to several gigabits per second in ideal situations, extreme low latency in near real-time communication between devices and immense scale to support a massive number of simultaneously connected devices to handle the growth of global data traffic which is projected to grow exponentially. Billions of devices will be connected to 5G networks worldwide that include smart phones, IOT devices and sensors; and generation of considerable economic gains is also expected from new digital services, business models and industrial solutions made possible by 5G technology. In the health sector, 5G facilitates applications such as telemedicine, real-time remote monitoring and robotic surgery. For these applications, connectivity should be reliable and the latency should be extremely low, and these can be satisfied by 5G technology, thereby medical professionals can carry out the diagnosis, monitor the health of patient even perform procedures from a distant location with high precision. Vehicle-to-everything (V2X) communication made possible by 5G in transport sector enable vehicles to communicate with each other and with road infrastructure which play a critical role in facilitating autonomous driving, reducing traffic congestions and improving road safety. Smart factories rely on 5G networks to make Industry 4.0 possible, the smart factories equipped with 5G networks support automation, robotics, and real-time data analytics to boost production efficiency. In a smart factory environment thousands of devices and sensors supported by Massive Machine-Type Communication networks, can be deployed to perform tasks like predictive maintenance, seamlessly collaborate with each other and monitor the production in real time. Smart cities use the potential of 5G to implement smart transport systems, energy grids and environmental monitoring and improved public services. Additionally augmented reality and virtual reality systems (AR and VR) heavily rely on high bandwidth and low latency to provide more immersive experiences.
