What is 5G?

5G is the fifth generation of cellular technology. It is designed to increase speed, reduce latency, and improve flexibility of wireless services. It is a new global wireless standard after 1G, 2G, 3G, and 4G networks. 5G enables a new kind of network that is designed to connect virtually everyone and everything together including machines, objects, and devices.

The 5G network will also simplify mobility, with seamless open roaming capabilities between cellular and Wi-Fi access. Mobile users can stay connected as they move between outdoor wireless connections and wireless networks inside buildings without user intervention or the need for users to reauthenticate.

5G technology will introduce advances throughout network architecture. 5G New Radio, the global standard for a more capable 5G wireless air interface, will cover spectrums not used in 4G. New antennas will incorporate technology known as massive MIMO (multiple input, multiple output), which enables multiple transmitters and receivers to transfer more data at the same time. But 5G technology is not limited to the new radio spectrum. It is designed to support a converged, heterogeneous network combining licensed and unlicensed wireless technologies. This will add bandwidth available for users.

How will 5G benefit businesses?

  • Autonomous mobility solutions
  • Smart factories
  • Virtual reality
  • Edge computing
  • Use of higher frequencies.
  • High bandwidth.
  • Enhanced mobile broadband.
  • A lower latency of 5 ms.
  • Higher data rates, which will enable new technology options over 5G networks, such as 4K streaming or near-real-time streaming of virtual reality.
  • The flexibility in coverage, having a mobile network made up of low-band, mid-band and mmWave frequencies.

5G wireless networks are composed of cell sites divided into sectors that send data through radio waves. Unlike 4G, which requires large, high-power cell towers to radiate signals over longer distances, 5G wireless signals are transmitted through large numbers of small cell stations located in places like light poles or building roofs. The use of multiple small cells is necessary, as the millimeter wave (mmWave) spectrum -- the band of that 5G relies on to generate high speeds -- can only travel over short distances and is subject to interference from weather and physical obstacles.

5G service is already available in some areas in various countries. These early-generation 5G services are called 5G non-standalone (5G NSA). This technology is a 5G radio that builds on existing 4G LTE network infrastructure. 5G NSA will be faster than 4G LTE. But the high-speed, low-latency 5G technology the industry has focused on is 5G standalone (5G SA).

RPA

RPA? How robotic process automation streamlines business processes Two kinds of RPA: Attended and unattended Attended automation Attended automation allows you to focus on more high-value work across your organisation. It does this by automating repetitive, manual, front-office activities and mimics actions you perform on your desktop or browser, like mouse clicks, by recording and playing back these actions in real time. Unattended automation By contrast, as its name suggests, unattended automation doesn’t require someone to be at their computer. Instead, unattended bots do the work by themselves recording and playing back actions. Because they can use triggers and schedule automated events, they’re ideal for accelerating the automation of high-volume tasks across your organisation. Faster ROI and improved compliance Because they don’t require custom code from the development team, bots are a very low-cost solution. They’re also easy to implement quickly. As a result, ROI from impleme

Internet of Things (IoT)

Internet of Things (IoT)? IoT has become one of the most important technologies of the 21st century. Now that we can connect everyday objects—kitchen appliances, cars, thermostats, baby monitors—to the internet via embedded devices, seamless communication is possible between people, processes, and things. By means of low-cost computing, the cloud, big data, analytics, and mobile technologies, physical things can share and collect data with minimal human intervention. Access to low-cost, low-power sensor technology Connectivity Cloud computing platforms Machine learning and analytics Conversational artificial intelligence (AI) With IoT, data is transferable over a network without requiring human-to-human or human-to-computer interactions. How does IoT work? An IoT ecosystem consists of web-enabled smart devices that use embedded systems -- such as processors, sensors and communication hardware -- to collect, send and act on data they acquire from their environments.
