The cost of building a private 5G network can vary significantly depending on factors such as the size of the deployment, the type of infrastructure used, and the specific use case requirements. However, here’s a general breakdown of the costs involved:

Spectrum: The cost of acquiring spectrum for private 5G can range from a few thousand dollars to millions of dollars, depending on the location, band, and licensing model.
Infrastructure: This includes the cost of radio access network (RAN) equipment, such as base stations and antennas, as well as core network components and edge computing resources. The cost can range from hundreds of thousands to several million dollars, depending on the scale of the deployment and the choice of vendor.
Devices: 5G-compatible devices, such as smartphones, IoT sensors, and industrial equipment, can be more expensive than their Wi-Fi counterparts. The cost will depend on the number and type of devices required.
Installation and integration: The cost of installing and integrating the private 5G network with existing enterprise systems can vary widely, depending on the complexity of the deployment and the level of customization required. This can range from tens of thousands to hundreds of thousands of dollars.
Ongoing operations and maintenance: The cost of operating and maintaining a private 5G network, including software upgrades, security patches, and personnel, can be significant. Annual costs can range from tens of thousands to hundreds of thousands of dollars, depending on the size and complexity of the network.

As an example, a small-scale private 5G deployment for a single facility may cost between $500,000 and $1 million, while a large-scale deployment across multiple sites could cost tens of millions of dollars.

However, it’s important to note that the cost of private 5G is expected to decrease over time as the technology matures and more solutions become available.

Yes, 5G networks can support legacy clients and non-3GPP technologies, and it is possible to achieve Quality of Service (QoS) across cellular and existing Layer 2 and Layer 3 campus networks. Let’s explore these aspects in more detail:

Legacy clients and non-3GPP technologies:

Dual Connectivity: 5G networks can support dual connectivity, allowing devices to simultaneously connect to both 5G and LTE networks. This enables legacy 4G devices to operate alongside 5G devices.
Non-Standalone (NSA) Architecture: 5G networks can be deployed in a non-standalone architecture, where the 5G RAN is supported by an existing 4G core network. This allows legacy devices to access the network while benefiting from 5G’s enhanced capacity and coverage.
Interworking with Wi-Fi: 5G networks can interwork with Wi-Fi networks using technologies like LTE-WLAN Aggregation (LWA) and LTE-WLAN Radio Level Integration with IPsec Tunnel (LWIP). These technologies enable seamless handover and aggregation of cellular and Wi-Fi traffic.

QoS across cellular and campus networks:

Network Slicing: 5G networks support network slicing, which allows operators to create multiple virtual networks with specific QoS requirements on a single physical infrastructure. This enables the prioritization of critical traffic and the allocation of dedicated resources for specific applications.
Quality of Service (QoS) Mechanisms: 5G networks have built-in QoS mechanisms, such as QoS Flow Identifier (QFI) and Guaranteed Bit Rate (GBR), which allow for the prioritization and allocation of network resources based on application requirements.
SD-WAN Integration: Integration of 5G with Software-Defined Wide Area Network (SD-WAN) technologies enables end-to-end QoS across cellular and campus networks. SD-WAN allows for the intelligent routing of traffic based on application requirements and network conditions.
Edge Computing: Deploying edge computing resources in close proximity to end-users can help ensure low-latency and high-quality service delivery across cellular and campus networks.

To achieve end-to-end QoS across cellular and campus networks, enterprises need to implement a comprehensive QoS strategy that encompasses both the 5G network and the existing Layer 2 and Layer 3 infrastructure. This may involve:

Defining QoS policies and traffic classification rules based on application requirements.
Configuring QoS mechanisms on network elements, such as routers, switches, and firewalls.
Implementing SD-WAN or other network orchestration technologies to ensure consistent QoS across different network domains.
Monitoring and optimizing network performance to ensure that QoS requirements are met.

By leveraging the capabilities of 5G and implementing a holistic QoS strategy, enterprises can support legacy clients and non-3GPP technologies while ensuring consistent performance across cellular and campus networks.
