What is 5G? – Understanding The New Technology


The next telecommunications standards - 5G is the coming fifth-generation wireless broadband technology. An important goal of 5G is to erase the differences between wireline and wireless networking to accommodate the growing mobility of network users. Major Specifications are.


Latency
5G wireless technology have must lower latency than 4G – latency being the time needed for a packet of data to move across a network or series of networks. Nokia believes 5G will be a system that provides a “scalable and flexible service experience with virtually zero latency” The below 1 ms latency will enable users to enjoy faster download and upload speed. Low latency will also facilitate real-time communication between a wide range of connected devices.

Bandwidth - Speed

Bandwidth refers to the amount of data that can be moved (uploaded or downloaded) through a network over a given time. 5G has a peak download speed of  20 Gb/s while 4G sits at just 1 Gb/s. From a peak speed perspective, 5G is 20 times faster than 4G.
Spectrum
One fundamental difference is 5G’s use of unique radio frequencies to achieve what 4G networks cannot. 4G networks use frequencies below 6 GHz, but 5G will likely use extremely high frequencies in the 30 GHz to 300 GHz range. We can stay connected everywhere includes high speed Trains (or) Planes.
Connection Density
4G connects 100 thousand devices per square km but 5G connects 1 million devices per square km. This upgraded network is to support the growing number of devices that demand internet access. This upgrade will boost up the sectors such as Internet of Things (IoT), Smart cities, Connected Cars, e-health etc,.
Date Traffic
5G will support 50 Exabytes / Month which is up from current level of 7.2 Exabytes / Month of 4G.
Energy Efficient
4G towers that fire data in all directions, potentially wasting both energy and power to beam radio waves at locations that aren't even requesting access to the internet. 5G also uses shorter wavelengths, which means that antennas can be much smaller than existing antennas while still providing precise directional control.

Secure Networks
5G provides more secure network which will be used for police and security professionals and gives more privacy.

Industry 4.0
5G will be an enabling factor for Industry 4.0. It help to improve flexibility in production, cut costs and create a safer working environment.
Internet of Things – IoT
Technologies like IoT (Connected Devices) are set to change the way machines and humans communicate. Devices will need to become smarter, as they will act as networking nodes rather than just terminals. 5G networks will be faster and smarter which accelerates the growth of IoT.

By 2019, 1.9 billion smart home devices are expected to be shipped. This could bring a potential revenue worth $490 billion. IoT smart devices have a deeper penetration in manufacturing, healthcare, and business than in our homes or phones. By 2025 the global worth of IoT tech is projected at $6.2 trillion, with the maximum value from healthcare ($2.5 trillion) and Manufacturing ($2.3 trillion). The number of internet connected “things” already exceeded our population back in 2008. By 2020 this number is expected to reach 50 billion. A whopping $19 trillion is anticipated as cost-savings and profits from this investments. The potential for future growth is massive. Only 0.06% of all the devices that could potentially leverage IoT are actually doing so. This makes the remaining 99.94% available for optimization. Of all the business who chose to implement IoT, 94% have already seen a return on their IoT investments. The market for sm...

In 2018, 60 percent of global manufacturers will use analytics data recorded from connected devices to analyze processes and identify optimization possibilities, according to  IDC and SAP . Report predicts that the IoT will lead to a 15 percent productivity increase in delivery and supply chain performance. Business Insider forecasts that by 2020, 75 percent of new cars will come with built-in IoT connectivity. According to Reportbuyer , there were 968,000 smart clothing units sold in 2015, a number that will reach 24.75 billion in 2021—a stunning 71.6 percent compound annual growth rate. Royal Dutch Shell realized a $1M return on a $87K investment in a remote IoT-based asset monitoring and maintenance solution that tracks activity across 80 oil fields in West Africa. Combined daily oil production across the oil fields is nearly 600,000 barrels.  IoT will bring a lot of savings in homes. Smar...
