At transfer rates of 20Gbps, a 5G connection is much faster and more efficient than 4G, with reliability almost at par with wired data transfers.
As Andreas Mueller, a 5G expert at Bosch quotes,
“Faster, better, farther. Striving for more is human nature, but it doesn’t always become reality. With 5G, it’s different. 5G is a standard of superlatives.”
Helps businesses stay competitive
Research indicates that there will be nearly 75 billion Internet of Things (IoT) connected devices worldwide by 2025, which is three times those in 2019. This suggests that the number of devices on the internet would be much more than the number of users. In the B2B space, IoT plays a significant role, which is augmented by this new communication standard of connectivity and automation engineered by 5G.
That said, it induces competition among businesses, compelling them to embrace this technology sooner in order to remain competitive.
Ensures the least time delay through low latency
With a very low latency of just 1 millisecond, a 5G connection paves the way for various useful innovations like autonomous vehicles. With its increased coverage, capacity, and low latency, 5G can remotely manage a fleet of vehicles, allowing them to make updates and receive responses in near real-time.
Is 5G really necessary?
Yes. Regardless of the industry, 5G will soon become a necessity if businesses have to scale. That said if we consider the military or defense realm, 5G is almost a mandate. In the growing age of global wars, nations must equip and empower themselves strategically and technologically.
This fifth-generation wireless cellular technology connection holds the potential to improve intelligence, surveillance, and reconnaissance (ISR), efficiently manage logistics, use virtual reality and augmented reality for training, and more. In addition, 5G holds the promise of instantly alerting about someone’s situation located anywhere on the Earth, access to crucial data on the battlefield, and the option of an unmanned airplane flying juxtaposed to a passenger aircraft.
These are just a handful of examples that showcase what 5G is capable of. However, to safeguard and secure their citizens, countries need to research and invest more in this technology, which is still in its infancy.
While this provides what this cellular technology can offer the military sector, it holds equally stellar opportunities for the IT industry. Due to its low latency, 5G provides an alternative for the IT sector to use a multitude of remotely managed applications. With human reaction times being much slower, these applications couldn’t perform to their utmost potential.
However, with 5G in place, the problem of slow response times will be tackled.

Understanding the difference between 4G and 5G
Apart from being the next version of 4G, there are other integral aspects/features that differentiate it from its predecessor.
On the speed parameter, 5G is capable of downloading 10 Gigabits per second, which is almost 100 times faster than its previous version. While 5G is still nascent, the speed it offers is much higher.
It is this feature of the 5G connection that makes it a perfect alternative for delivering the high-speed networks needed for advanced gaming, autonomous driving, and other complex applications. However, the connectivity speed required for a use case depends purely on the purpose intended.
For example, live streaming a football match and managing a driverless car require different connection attributes regarding speed, latency, and security. To tackle the modern disruptive requirements, businesses need extremely high speeds supported only by 5G. Furthermore complex simulations can be sent to customers without difficulty, experts can support medical interventions by transmitting camera images in real-time, and entire cities can become smart cities.
Network slicing is the primary feature that offers all the capabilities that make 5G a robust enhancement over other cellular technologies. Standalone 5G, which is cloud-based and virtual, has most of its network elements as software instead of hardware. This makes it possible for telecommunications to create network slices that enterprise private owners can tailor according to their requirements of security, capacity, encryption, and speed.
5G ensures that these customizations are implemented by letting the enterprises access and control the specific slice SIM. These slices are capable of being stored in any 5G SIM.
While speed is one aspect, equally significant is latency – the time delay between sending a message and the corresponding response. With an extremely low latency of just 1 millisecond, 5G is much more efficient in this metric as well, in contrast to 4G at 200 milliseconds. Such low latency makes 5G capable of offering exceptional services and opening the gateways to newer dimensions.
Focus on security and regulations
As 5G comes with possibilities for immense speed, it emphasizes enterprise owners and third-party vendors on security and compliance. For example, in the EU, the stakeholders will be impacted by the ePrivacy Regulation (ePR) that focuses on privacy and encryption of personal data.
It was initiated with the objective of working in tandem with the EU’s General Data Protection Regulation (GDPR) in 2018. However, the status of ePR is still to be decided.
Point apart, 5G offers its in-built security mechanism to service providers through 5G SIM. This ensures the sensitive data is stored in an encrypted form within a secure component.
How do I find out if I have 5G?
To find out if there’s 5G availability, users can check the “SIM & Networks” and the “Preferred Network” options on their handsets. Do note that users will need a device that supports 5G. If they can see the 5G option in the list of networks available, that implies it’s very much ready! The device may auto connect to 5G as well if there is sufficient signal and the device supports the 5G bands in the particular area.
While individuals who watch videos or live streaming online would certainly enjoy the 5G experience, businesses will also have various advantages. Especially for those who run cloud-based apps, use enterprise software, or need to connect with customers across the globe, 5G is a boon. Especially when away from offices and WiFi networks.
