Fifth-generation wireless is the latest version of cellular technology designed to significantly increase the speed and responsiveness of wireless networks. The adoption of 5G will enable a steep increase in the amount of data transmitted due to more available bandwidth and advanced antenna technology. 5G layers several different frequency technologies together to deliver its potential of great speed, low latency and high capacity. 

mmWave “millimeter wave” is a short-range, high-frequency network technology with a wave spectrum between 30 GHz and 300 GHz. It is the next ‘wave’ of 5G and is considered to be the way to bring “5G” into the future by allocating more bandwidth to deliver faster, higher-quality video, and multimedia content and services. 

Applications

Mission Critical Control Applications Due to its projected network latency of less than one millisecond, mmWave 5G can be deployed for services such as vehicle-to-vehicle communications, drone communications and other time-sensitive, high-reliability applications.
Fixed Wireless Internet Access The gigabit data rates of 5G mmWave can replace a number of Internet access technologies with hybrid fiber and wireless networks connecting subscriber homes. 
Outdoor urban/ suburban cells Provision of increased capacity in high-demand public spaces and venues. With cell sizes being around 100m, small 5G mmWave access points can be placed on poles or buildings to provide the coverage required. 
Indoor Hotspot Cells Shopping malls, offices and other indoor areas require a high-density of 5G mmWave micro cells. These small cells have the potential to support download speeds to up to 20 Gbps, enabling seamless access to cloud data and the ability to support multiple applications, as well as various forms of entertainment and multimedia.
Internet of Things Data collection, control, and analysis for the general connectivity of objects, sensors, appliances and other devices. It has the potential to cover smart home applications, security, energy management, logistics and tracking, healthcare, and a multitude of other industrial operations. 

Challenges

In order to overcome unfavourable channel properties such as high path loss, propagation loss and rain fading, mmWave 5G will require technologies like beam-forming, beam-tracking together with phased array antennas.
