What is 5G?

5G is the next generation of mobile communication. More than just faster speeds, 5G will be a whole new kind of network. One we expect to be faster, smarter, and able to respond in close to real time. A network that will ultimately enable new experiences that will change how we live, work, and play..The connectivity benefits of 5G will make businesses more efficient and give consumers access to more information faster than ever before.

The networks will help power a huge rise in Internet of Things technology, providing the infrastructure needed to carry huge amounts of data, allowing for a smarter and more connected world.

5G networks will operate in a high-frequency band of the wireless spectrum, between 28 GHz and 60 GHz. This range is known as the millimeter wave (mmWave) spectrum. The sub-6 GHz range that LTE calls home will also be used. 5G is expected to add unlicensed frequencies such as the 3.5 GHz to its list of new frequencies for mobile use. This means a lot of bandwidth will be available to users.

In addition to greater bandwidth, the new 5G networks will have a dense, distributed network of base stations in the small cell infrastructure. This will allow more processing to happen on the edge, leading to lower latencies.

Difference between 4G and 5G

The fourth generation (4G) of mobile connectivity started to make waves in the late 2000s. 4G made mobile internet speeds up to 500 times faster than 3G and allowed support for HD TV on mobile, high–quality video calls, and fast mobile browsing.

4G is now common throughout the world, but things are about to change again. The Internet of Things (IOT) is now a real possibility and 4G will not be able to manage the huge number of connections that will be on the network. It is expected that there will be more than 20 billion connected devices by 2020, all of which will require a connection with great capacity. This is where 5G comes into force.

What makes 5G so different from 4G?
5G is widely believed to be smarter, faster and more efficient than 4G. It promises mobile data speeds that far outstrip the fastest home broadband network currently available to consumers. With speeds of up to 100 gigabits per second, 5G is set to be as much as 100 times faster than 4G.

Requirements of a 5G network

Previous generations of mobile networks addressed consumers predominantly for voice and SMS in 2G, web-browsing in 3G and higher-speed data and video streaming in 4G. The transition from 4G to 5G will serve both consumers and multiple industries. With global mobile data traffic expected to grow eight times by the end of 2023, there is a need for a more efficient technology, higher data rates and spectrum utilization. New applications such as 4K/8K video streaming, virtual and augmented reality and emerging industrial use cases will also require higher bandwidth, greater capacity, security, and lower latency. Equipped with these capabilities, 5G will bring new opportunities for people, society, and businesses. More efficient networks will address the capacity needs from the growing mobile data traffic. Industries will be transforming by new capabilities brought on by 5G.. Examples of these capabilities include: 1. The ability to download a full-length HD movie in seconds 2. The quick reaction time (low latency) to enable remote robotics 3. The ability to spin up virtual networks on-demand with network slicing 4. Battery lifetimes beyond 10 years for remote cellular devices Up to 100 times faster data rates: instant access to services and applications Network latency lowered by a factor of five; use cases in areas such as manufacturing, automotive, energy and utilities, healthcare Mobile data volumes expanded by a factor of 1,000 10x better battery life: remote sensors and more sustainable networks.

How 5G Works?

Like other cellular networks, 5G networks use a system of cell sites that divide their territory into sectors and send encoded data through radio waves. Each cell site must be connected to a network backbone, whether through a wired or wireless backhaul connection.

5G networks use a type of encoding called OFDM, which is similar to the encoding that 4G LTE uses. The air interface will be designed for much lower latency and greater flexibility than LTE, though.

The new system is also designed to operate on much larger channels than 4G is, to carry higher speeds. While most 4G channels are 20MHz, bonded together into up to 160MHz at a time, 5G channels can be up to 100MHz, with Verizon using as much as 800MHz at a time. That’s a much broader highway, but it also requires larger, clear blocks of airwaves than were available for 4G

5G networks need to be much smarter than previous systems, as they’re juggling many more, smaller cells that can change size and shape. But even with existing macro cells, Qualcomm says 5G will be able to boost capacity by four times over current systems by leveraging wider bandwidths and advanced antenna technologies.

The goal is to have far higher speeds available and far higher capacity per sector, at far lower latency than 4G. The standards bodies involved are aiming at 20Gbps speeds and 1ms latency, at which point very interesting things begin to happen.

 

Who is launching 5G?

AT&T(American Telecommunication Company) launched 5G in 12 cities on December 21, 2018 with one mobile internet hotspot, the Netgear Nighthawk 5G. It raised its city count to 19 in April.

AT&T is now offering 5G services to mobile customers in a total of 19 cities across the U.S. The company has expanded its mobile 5G offerings to parts of seven new cities: Austin, Texas; Nashville, Tennessee; Orlando, Florida; and California cities Los Angeles, San Diego, San Francisco, and San Jose. .AT&T seems to be only giving out a few hotspots per city, and covering a few neighborhoods in each city. It’s offering service for free right now. I expect AT&T will have retail service plans and coverage maps, along with its first 5G phone, the Samsung Galaxy S10 5G, in mid-June.

Sprint  has also announced the initial launch of its mobile 5G network, bringing 5G connectivity to Sprint customers in areas of Atlanta, Dallas-Fort Worth, Houston, and Kansas City.

In India, Airtel launches India’s 1st 5G Capable Network. Silicon Valley of India, Bengaluru and superstar metropolis of yesteryears, Kolkata have become the lucky Indian cities to get India’s first 5G Cities. Airtel has just deployed Massive Multiple-Input Multiple-Output (MIMO), which has been claimed to be India’s first 5G capable networks.
