ASOCS Virtual Base Station (vBS)
The vBS is a fully virtualized Base Station capable of running software of all layers and functions, including Baseband L1 PHY real-time processing, on virtual machines. It enables high capacity and coverage in any environment and on any scale, from In-building with Distributed Antenna Systems (DAS), through Metro Networks in dense urban areas, to Mega-scale networks covering entire cities.
Virtualization of baseband processing on Commercial Off-the-Shelf (COTS) servers reduces operational and capital expenditures. Performing real-time baseband processing enables intelligent scaling of computing resources as demand on capacity fluctuates, while reducing site lease costs, energy usage, and maintenance expenses, and eliminates the need to over provision base stations to meet peak demand.
An End-to-End vRAN Solution for In-Building
The integration of the vBS with a digital Distributed Antenna System (DAS) creates a powerful end-to-end coverage and capacity solution for in-building Radio Access Networks (RAN). This integrated solution decreases the amount of proprietary hardware needed, improves coverage, cell edge throughput and spectral efficiency, and supports incremental addition of resources without having to rip-and-replace elements.
Enabling Open Mobile Edge Clouds
The rise of new applications such as Virtual Reality (VR), autonomous cars, smart stadiums, and cloud robotics, impose demanding requirements on networks, including ultra-low latency and localized processing. It also requires functions of the mobile core network to move closer to the user. The vBS architecture enables an ultra-low latency Open Mobile Edge Cloud with direct access to real-time radio network information, capable of reducing network bandwidth consumption, allowing service customization and enhancing the mobile broadband experience.
vRAN Solution for Macro Networks
The vBS can support any baseband partitioning architecture depending on the carrier’s needs:
1. Open Mobile Edge Cloud at Central Office with dark fibers to the Cell Sites
2. Hybrid Open Mobile Edge Cloud for real-time processing and Centralized Cloud for none-real-time functions
a. This topology allows Carriers to centralize none-real-time functions at first, when no dark fiber is available and run applications at the central office location
b. Carriers can leverage the Open Mobile Edge Cloud to run all functions and applications at the network edge, which is critical for low-latency applications. Enterprises will benefit from a local network breakout, allowing certain types of information to stay locally without traveling outside of the Enterprise gateway.
c. The Open Mobile Edge Cloud can serve a local cell site and any adjacent cell site that is connected with fibers, forming a super-cell (diagram 2).
