* **Streamlined Security and Operations** – Integrated tools for SIM lifecycle management, security policy enforcement, and software updates provide centralized control with minimal operational overhead.
* **Future-Ready by Design** – GXC’s architecture supports software-defined upgrades, modular expansion, and full alignment with 3GPP and Open RAN standards—keeping your network ready for tomorrow.
### Key Concepts
GXC 5G Architecture
#### Core System Components
* **Onyx Edge: Integrated Edge Compute Platform** – A compact, all-in-one on-site appliance that integrates the 5G Core, Central Unit (CU), and Distributed Unit (DU). Onyx Edge enables low latency, local breakout, and on-premises application hosting—streamlining deployment and reducing external dependencies.
* **5G Core (5GC)** – Embedded within Onyx Edge, the 5G Core manages control and user plane functions such as authentication, session management, and mobility handling. This ensures data sovereignty and real-time responsiveness for enterprise applications.
* **Radio Access Network (RAN)** – Implements a 3-layer RU–DU–CU architecture using the O-RAN 7.2x functional split. Real-time processing occurs at the edge (DU), while the CU handles centralized control—enabling proximity-based radio access and high-performance, low-latency communications.
* **Transport Layer** – Connects the Onyx Edge to distributed RUs via high-speed, time-synchronized links using IEEE 1588v2 Precision Time Protocol (PTP) and Synchronous Ethernet (SyncE). This enables deterministic performance, low jitter, and precise timing for 5G fronthaul and TDD alignment.
* **Fronthaul Multiplexer (FHM)** – Aggregates and synchronizes traffic between the DU and connected RUs. FHM abstracts individual RUs into a unified radio layer, simplifies network design, and ensures cohesive coverage with minimal operational overhead.
* **Onyx Portal** – A cloud-native management interface providing a single pane of glass for configuring, monitoring, and managing private networks. It offers real-time visibility into network, equipment, and subscriber metrics, simplifying enterprise deployment and operations. The portal also supports integration with external systems via open APIs.

* **Mesh Node** – Enables wireless backhaul between a GXC Gateway Node and Access Points (APs) using self-interference mitigation techniques. Paired with a Mesh AP and orchestrated via the Onyx Platform, it delivers rapid, cable-free coverage extension—ideal for environments where wired infrastructure is unavailable.
#### Functional Capabilities
* **5G Standalone** – 5G deployment model that delivers low latency, high throughput, and flexible architecture through an on-premises, service-based core.
* **Open RAN-based Private Wireless** – Offers significant advantages including reduced costs using commercial off-the-shelf components, flexibility in selecting edge compute and radio units from multiple vendors, and support for a wide range of global frequency bands. Additionally, it enables transparent and touchless software upgrades, supports feature evolution—such as ultra-low latency, RedCap, and zero-frame drop broadcasting—without requiring hardware replacement. Critically, it allows for phased integration with existing infrastructure, avoiding costly rip-and-replace scenarios while ensuring scalable, future-ready connectivity.
* **Shared Cell Architecture with a Unified Radio Layer** – Enables multiple RUs to function as a single logical cell under one DU enabling more efficient spectrum utilization. This architecture improves user mobility, eliminates intercell interference, and simplifies RF planning—particularly in high-density environments like factories and warehouses.
* **DAS Support and Integration** – Support for both passive and active Distributed Antenna Systems (DAS) enabling shared infrastructure for public and private networks. It supports 1, 2, or 4-port MIMO distribution, automatic CBRS SAS registration, and both RF and O-RAN DAS interfaces—delivering centralized, cost-effective coverage even in complex venues.
* **High-Capacity, Flexible Spectrum Support** – Supports up to eight simultaneous carrier frequencies and synchronized TDD operation, allowing for optimized uplink/downlink balance, expanded coverage, and efficient spectrum utilization.
* **CBRS and Open Standards Support** – Fully compatible with CBRS and other localized spectrum bands. Adheres to O-RAN and 3GPP standards, ensuring vendor interoperability and seamless integration into existing enterprise IT infrastructure.
* **End-to-End Security** – Embedded across all layers, including SIM-based authentication, role-based access control, traffic segmentation, encryption, and secure management protocols. This ensures robust security and regulatory compliance.
## Summary
GXC’s 5G private wireless solution empowers enterprises with a future-ready network designed for performance, flexibility, and control. With an edge-based architecture, it delivers low latency and high-capacity throughput, making it ideal for real-time, bandwidth-intensive applications.
