Last updated on 

Parallel Wireless is a company that provides Open RAN (Radio Access Network) solutions. Open RAN is an initiative that aims to disaggregate and standardize the components of the traditional RAN, allowing for interoperability and flexibility. Parallel Wireless Open RAN is a solution designed to bring openness, flexibility, and cost-effectiveness to radio access networks. Here are technical details about Parallel Wireless Open RAN:

1. Open RAN Architecture:

a. Disaggregation:

  • Open RAN involves the separation of hardware and software components within the RAN, enabling interoperability and avoiding vendor lock-in.

b. Functional Splits:

  • Open RAN defines functional splits between different RAN components, such as the radio unit (RU), distributed unit (DU), and centralized unit (CU).

2. Parallel Wireless Open RAN Components:

a. Radio Unit (RU):

  • The RU includes the physical radio transceiver and antenna components.

b. Distributed Unit (DU):

  • The DU handles baseband processing functions, including modulation, coding, and beamforming.

c. Centralized Unit (CU):

  • The CU manages higher-layer functions, such as radio resource management and connection establishment.

d. Intelligent Controller:

  • An intelligent controller oversees the coordination and management of the different RAN components for optimal performance.

3. Open Interfaces:

a. Xn Interface:

  • The Xn interface facilitates communication between different DUs in the network.

b. Fronthaul Interface:

  • Open RAN uses open fronthaul interfaces, allowing interoperability between RUs and DUs from different vendors.

4. Virtualization and Cloud-Native Principles:

a. Virtualized Network Functions (VNFs):

  • Functions traditionally performed by dedicated hardware are virtualized and run as software on standard servers.

b. Containerization:

  • Containerization technologies (e.g., Docker) may be employed for efficient deployment and management of virtualized functions.

c. Cloud-Native Architecture:

  • Adherence to cloud-native principles enables scalability, flexibility, and efficient resource utilization.

5. Intelligent Self-Optimization:

a. Automation:

  • Intelligent algorithms and automation are used for self-optimization of the network, including self-configuration and self-healing.

6. Multi-Vendor Interoperability:

a. Vendor-Neutral Approach:

  • Parallel Wireless Open RAN supports a vendor-neutral approach, allowing operators to choose components from different vendors.

b. Interoperability Testing:

  • Rigorous testing is conducted to ensure interoperability among components from various vendors.

7. Dynamic Spectrum Sharing:

a. Efficient Spectrum Utilization:

  • Dynamic spectrum sharing techniques are employed for efficient use of available spectrum resources.

8. Use Cases:

a. Rural Deployments:

  • Open RAN can be particularly beneficial in rural deployments where cost-effective and flexible solutions are crucial.

b. Enterprise Networks:

  • Deployments in enterprise environments can benefit from the flexibility and scalability of Open RAN.

9. Network Slicing Support:

a. Isolation of Resources:

  • Network slicing allows the isolation of resources to cater to specific service requirements, providing tailored connectivity for diverse use cases.

10. Evolution to 5G:

a. 5G NR (New Radio):

  • Parallel Wireless Open RAN is expected to evolve to support 5G NR and its enhanced features.

Summary:

Parallel Wireless Open RAN is a solution that embraces the principles of Open RAN, aiming to bring openness, flexibility, and cost-effectiveness to radio access networks. The disaggregated architecture, open interfaces, virtualization, and cloud-native principles contribute to the adaptability and efficiency of the network. The focus on multi-vendor interoperability and intelligent self-optimization aligns with the broader industry trends in evolving RAN architectures.
