Where masks are the new normal under Covid19 horror show, then 5G is the upcoming new normal in the generation today. In the limelight is the showstopper, 5G, a fifth generation technology standard for broadband cellular networks. The deployment of such technology started in 2019. 5G remains a planned successor to the companies that owns 4G networks and provide services round the globe. Predicting 1.7 billion subscribers round the world till 2025, the technology is ready to give a bang on experience to the users. With bells and whistles stringed, 5G Network will swiftly grip and curb the distances in no time. One could just envisage the affects and in a jiffy things will take a techno- beauty turn, ironical!

The speed improvement is beyond imagination, not only this technology is hitting the market but it cutting edge in many ways, unbridling massive 5G IoT, Internet of things eco system, where networks can feed the communication system for billions and billions of systems attached under one roof or any corner of the world, with the right tradeoffs between latency, speed and cost. Now this might leave one wondering, what does 5G actually possesses to offer? In a nutshell, it is a highly integrated kid, ready to bloom in the world and set the stage on fire!

Driven with 8 major specification requirements, 5G is acing the tech world.

·        Up to 10Gbps data rate - > 10 to 100x speed improvement over 4G and 4.5G networks

·        1-millisecond latency

·        1000x bandwidth per unit area

·        Up to 100x number of connected devices per unit area(compared with 4G LTE)

·        99.999% availability

·        100% coverage

·        90% reduction in network energy usage

·        Up to 10-year battery life for low power IoT device

Maxing out at 10 Gigabits per second 5G is the star of the show. How about rewinding the race to where it started from.  When it comes to speed 3.5G/ DC-HSPA + gave 42.2 Mbps, quite slow for today? Well thanks to the inventor, blessed with speed though! From behind came gushing 4G/LTE, giving a rise to100 Mbps, well that was a huge rise. Following this under the limelight came4G/LTE Cat. 4 with a speed of 150 Mbps. Giving the world another boost was4G/LTE Advanced with a speed of 1000 Mbps, pushing buttons to get the best now 5G is the show stopper with a speed of 10,000 Mbps. What a jump!

Conferring to communication principles, the squatter the frequency, the larger the bandwidth. That’s something common for the tech experts in the field. The use of smaller frequencies (millimeter waves between 30GHz and 300GHz) for 5G networks is why 5G can be faster. This high-band 5G spectrum delivers the anticipated boost not only in speed but also in volume, low latency, and value.

The word latency above is definitely playing with the nerves in your mind, well for the newbies getting in line with technology, it is eminent that you need to act cool while talking about 5G, let’s hit the road to understand what on earth LATENCY is?

5G technology bids a tremendously squat latency rate, the interruption between the transfer and reception of information. From 200 milliseconds for 4G, we travel down to 1 millisecond (1ms) with 5G.

Just give it a thought, the speed is totally bizarre.
A millisecond is 1/1000 of a second. 

The typical response time for humans to a visual stimulus is 250 ms or 1/4 of a second. People are crowned at around 190-200 ms with appropriate training.

Visualize now that your car could react 250 times faster than you. Picture that it could also respond to hundreds of inbound information and can also interconnect its responses back to other vehicles and road signals all within milliseconds.

At 60 mph (100km/h), the retort distance is about 33yards (30 meters) before you pull on the brakes. With a 1ms reaction time, the car would only have trolled a bit more than one inch (less than 3centimeters). Isn’t this something and beyond?

When it comes to the security, 4G networks use the USIM application to achieve strong reciprocated authentication between the user and the connected device and the networks.

The unit accommodating the USIM application can be a detachable SIM card or a rooted UICC chip. 

This sturdy mutual authentication is vital to empower trusted services. Today, security solutions are already a mix of security at the brink(device) and security at the basic (network). Numerous security frameworks may co-exist in the forthcoming, and 5G is likely to re-use existing solutions used today for 4G networks and the cloud (SEs, HSM, certification, Over-The-Air provisioning, and KMS). The standard for strong mutual authentication for 5Gnetworks was finalized in 2018. 

The need for 5G sanctuary, secrecy, and trust will be as strong as for 4G, if not stronger, with the increased impact of IoT services. Local SEs in devices can secure network access and support secure services such as crisis call management and cybernetic networks for IoT. 

This was all to give you a small trip round 5G, grow andcreate masterpieces with fast pace technology resting on your palms, ready to get explored.
