What is 5G?

5G is the fifth-generation technology introduced to cellular networks, which began to be deployed worldwide in 2019. By 2024, 5G and eSIM are projected to reach 40% of the world’s population and will have 1.5 billion subscriptions to the services, making it the fastest next generation to date.

5G enables a new kind of network service that offers much faster data transmission speed, low latency and ability to connect many devices. It follows its predecessors; 3G, which led to the mass use of the smartphones, 4G, which allowed for faster browsing, while 1G was about voice and 2G enabled short messages.

According to Qualcomm’s 5G Economy study, they found that 5G’s full economic effect will likely be realised across the globe by 2035—supporting a wide range of industries and potentially enabling up to $13.1 trillion worth of goods and services.

There are many benefits of 5G.

  • improving network connectivity with a faster, reliable, and guaranteed connection
  • more significant number of connected devices such as(drones, vehicles, robotics)

The outcomes from the benefits of 5G are multipurpose, impacting a varied number of industries. The connectivity provided by 5G is exploring the potential for new, innovative services. But what about the doubts surrounding 5G?

How can mobile operators better address the risk of subscriber privacy breaches in 5G?

In today’s connected world, mobile networks carry a constant footprint of subscriber’s digital activities. The amount of connected devices means there is constant data exchange – and those are susceptible to privacy breaches. Thanks to the introduction of a new 5G standardization feature that promotes subscriber privacy, Mobile Network Operators can answer these concerns with the 5G eSIM. In short, the aim of the new 5G authentication is to add privracy & secrecy on Subscrption Identifier (i.e identity of the User).

The aim of 5G authentication is to add privacy/secrecy on Subscription Identifier (i.e. identity of the User). Different protection profiles are defined in new standards : they enable credentials encryption to generate a SUCI (Subscription Concealed Identifier). This new feature will be available in the nex features of our Helios 5G Operating System.

What are the security issues of 5G?

With 5G networks increasingly based on software, risks related to significant security flaws, such as those deriving from inefficient software development processes within suppliers, providing backdoor entry to the snoop on data. 

Another security risk is the protocol designed to allow 4G or 3G connections when a dependable 5G signal isn’t available. When a 5G device switches to 3G or 4G, it’s open to the vulnerabilities that are not a concern in the previous generations’ protocol.

The biggest issue currently surrounding the introduction of 5G is the security of the consumer’s data. Although consumers can receive low latency and 100% coverage, enabling IoT devices, there are challenges that operators are currently battling, such as a lack of infrastructure, resulting in the need for investment.

The question is, will 5G technology be as secure as it could be and meet expectations?

MNOs & 5G

5G is heading a new way forward for businesses to innovate while creating opportunities for mobile network operators (MNOs).

Each generation of technology has created obvious opportunities within the telecommunications sector. With the introduction of 5G, the industry believes this would open opportunities to secure value from new use cases and broader adoption of IoT. However, operators are aware of the increased need for infrastructure investment as pressure on the network keeps growing.

5G and eSIM

5G will be the best innovation vector for businesses, as it will disrupt the way we think connectivity for housing, for enterprises, for the automotive sector and so on – and thus create new uses. It will be tightly linked to the digital transition that has started to happen in enterprises, in infrastructures and in consumption modes. While it may be criticized to replace human work by machines, it will also be a path to work creation through its new applications. In order to seize those opportunities, MNOs need to prioritize use cases in line with their long-term strategy and acquire 5G spectrum while minimizing OpEX and expenditures.

5G & eSIMs

The 5G network will be an evolution of the 4G network in terms of security and adaptation for the new uses and the quantity of objects to connect to the network in the years to come. When massive IoT will start expanding, Wifi won’t be adapted to the quantity of connexions and cellular connectivity through eSIM will become the norm. Moreover, 5G is the best network for eSIMs. From a consumer standpoint, it enables a full digitalisation of the customer journey. From an enterprise standpoint, it enables an automation and data analysis thanks to eSIM-equipped sensors. From a use-case perspective, it enables to create new applications that weren’t possible before with 4G; and with previous standards of SIMs: connected cars, commercial good tracking, connected cities, augmented reality in the medicine or leisure area.

This is why Oasis has developed Helios, its 5G eSIM to enable OEMs to tackle the challenges of 5G:

  • Onboard identity encryption capabilities into Oasis’ 5G eSIMs
  • Cyber resilience to maintain a trusted environment
  • Highly-Perfomant OS to ensure that Mobile Operators can offer users a seamless & optimal 5G romain experience

Oasis Smart Sim is also the world’s first company to have developed a SIM Free Cloud eSIM, Velios-as-a-Service, designed to tackle the challenges impending mass growth of IoT on 5G networks, with an ultra-secure mobile network authentication service, a drastic reduction of IoT Solution Provider’s costs and new uses cases enabling new approaches to connectivity and a cost-effective solution for OEMs.
