Rise in private 5G networks for Enterprise

With the evolving digitalisation of technology for faster and more reliable business communication, the deployment of Private 5G networks (P5G) has garnered attention across enterprises.

Proof of concept and trial deployments have been underway, showcasing the potential of private cellular networks in revolutionising enterprise connectivity. This article delves into the intricacies of private 5G networks discussing:

• Definition of private 5G.
• How businesses can benefit from private 5G.
• Deployment models.
• Spectrum-related requirements.
• Security considerations.
• Emerging trends.

What is private 5G technology?

5G represents the fifth generation of cellular technology. While earlier generations of cellular technology (such as 4G) focused on ensuring connectivity, 5G takes connectivity to the next level by delivering connected experiences from the cloud to clients (up to 20 gigabits per second).

A private 5G network is the next generation of Local Area Network (LAN). 5G has been engineered to enhance the velocity, reduce latency, and improve the flexibility of wireless networks.

The impact of private 5G for businesses?

Private 5G is an enabler for leveraging a new level of connectivity that leads to higher business production, performance, and innovation. For enterprises striving for a ‘digital future’, looking to leverage technologies such as AI, robotics, Internet of Things (IoT), a 5G private network is crucial.

With speeds up to 100 times faster than 4G and 10 times the speed of average broadband, it proves the exceptional performance that businesses can access. An exciting era of digital transformation. According to BT, by “2025, 35% of businesses will have invested in 5G infrastructure“. This technology is becoming increasingly accessible throughout the UK.

Availability of spectrum

One of the primary requirements for enterprise wireless use cases is the availability of a suitable and cost-effective spectrum. While licensed spectrum owned by Communications Service Providers (CSPs) offers rich spectrum sources, it can be costly for enterprises. Alternatively, unlicensed spectrum, including IEEE 802.11ax (Wi-Fi 6) and expanded 6GHz access with Wi-Fi 6E, has emerged as a preferred choice due to its cost-effectiveness. However, for outdoor use cases requiring extensive coverage, licensed spectrum may be necessary.

Area of coverage

Enterprises today have diverse physical footprints, ranging from campuses with indoor and outdoor spaces to distributed remote sites and branch offices. Private cellular coverage, enabled by powerful radios, addresses the challenge of outdoor coverage, offering flexibility for enterprises to deploy privately owned solutions or opt for managed services offered by carriers.

Security considerations

Security is paramount in any private cellular solution, with enterprises prioritising data sovereignty and protection against potential breaches. Aligning private 5G devices with enterprise identity management and access control engines ensures compliance with stringent security policies. Many enterprises prefer wired connections or enterprise-owned and operated connections to mitigate security risks.

Deployment models

Enterprises have multiple deployment models to consider when implementing a private 5G solution. They can choose to build and operate their own network, contract Managed Service Providers (MSPs) for installation and operation, or collaborate with CSPs for private network slices. Each model offers unique advantages and challenges, depending on factors such as cost, complexity, and performance requirements.

Spectrum related requirements

5G radio-access technology operates in two frequency ranges: Frequency Range 1 (FR1) and Frequency Range 2 (FR2). Different frequency bands offer complementary characteristics, with low bands ideal for coverage, mid bands for capacity, and high bands for major capacity boosts.

Enterprises must consider factors such as Frequency Division Duplex (FDD) and Time Division Duplex (TDD) LTE bands when deploying private wireless networks.

Lease a 5G network slice

Another procurement method involves leasing a network slice within a public 5G network. Network slicing enables organisations to isolate their network traffic while leveraging the security benefits of 5G. Enterprises can tune specific characteristics of their 5G service and prioritise traffic using Quality of Service (QoS). However, network slices are available only within the service area of the operator, requiring careful consideration for broader geographic coverage.
