The 5G Fundamentals & Foundations for Novice

Is 5G getting a lot of hype, but it deserves to. 5g Community friends, in this quick catch-up, we will be having conversations around the generation of mobile communications explore how the technology works and the new applications by leveraging the power of 5G.

The advent of 5G promises to change our lives in a radically big way. This revolution will transform cars to be self-driving, communication networks to be software-defined and autonomous, virtual reality and augmented reality to be mobile and completely untethered, and internet of things (IoT) sensors to be intelligent and connected. Behind this 5G revolution, AI plays a significant role in the planning, forecasting, building, development, and deployment of 5G. It also enables a new set of experiences, including intelligent stores and factories, autonomous flying drones, robots, and holographic meetings.

By reading this, we can make you ramp up on 5G, what they mean, how they work, and how they can help us. First and foremost, let's see, we'll see precisely why 5G is such a difference over previous generations of mobile communication. We have not included the dull specifics of bandwidth and latency numbers of 5G. Instead, we discussed the real-world impacts and focused on the kinds of things this now makes possible. We will cover fundamental terminologies like mmWave, Massive MIMO, Platooning, Beamforming, and more.?

5G != Only Faster Downloads. Faster is a great deal, but is it a big deal? But it is not a good way to look at what the 5G brings us the value of business use cases.

High-Level Architecture:

2G, 3G, 4G, 5G Phone, is new "G" in a couple of months and years, so is it worth waiting for 6G then. The answer is no because each technology revolution from legacy to 5G took approximately ten years or more. So, tap 5G now, as 5G is rolling out in many places and industries. And we don't call the first edition 1G because we don't have comparative. So generations must overlap and co-exist. And each generation is improving on the way to the next with better speed, efficiency at across-the-board.?

Government and Industry bodies will be governing the frequency allocation, and sometimes it is called spectrum allocation and spectrum management (low 0KHz high 300 GHz). The ranges of the radio spectrum are reserved for specific use cases and industries like radio, television, aeronautical, mobile, satellite, and more.?

So, 5G frequency ranges are sub-6(low under 6GHz) to mm Wave (high 24~40 GHz). mm Wave is excellent, but we have challenges with consistency and reliability, where massive research is in place.?

When we talk about the bandwidth, the speed is fast enough for downloads. Is the rate only matters? Nope, the more use cases are more aligned with streaming, VR/AR with examples Xbox cloud gaming, google stadia, PlayStation now, and amazon luna. It is accomplished with the help of the Array of Antenna. So, the cell which connects to the array of antenna brings the concept of MIMO. It means Multiple Input, Multiple Output, if we have lot of antenna's then it is called Massive MIMO.

Latency Requirement & Use cases:

5G QoS (Quality of Service), with this approach we can able to create a specific applications and prioritize the applications on the network can done based on use case need. Beamforming & MIMO is not unique, to 5G but much more vital to improve efficiency with energy. So, with the bandwidth more band width is better. With latency is less is better.?5G 10~20 ms of latency... example latency in gaming is very vital. autonomous vehicle needs low latency.URLLC - Ultra Reliable Low Latency Communication use cases like autonomous vehicles, vehicle to vehicle communication, robotics, medical applications, VR/AR. Ultra‐reliable low‐latency communication (URLLC), also known as critical communication (CriC), is a use case characterized by the need for very low latency, often in conjunction with very high reliability.

Use Cases:

5G platooning. A key part of the 5G specification is URLLC (Ultra-Reliable and Low Latency Communications), which allows for reliable, instant communications between the network and devices.?This is what makes the era of driverless cars a very real possibility, by allowing vehicles to communicate their exact speed and position with each other in real-time.?Known as?Cellular-V2X (C-V2X), it could eventually lead to platooning, which will get traffic moving faster. Groups of vehicles in a connected platoon will be able to drive with a one-second gap between each vehicle, automatically matching each other’s speed and braking.

So, to conclude, 5G is excellent not only for the media, which will disrupt the entire cross-domain & industry use cases. And with that 5G, the other complementary technology worth exploring is edge computing.
