Linux Base Station Platform for Next Generation Radio Access Networks

Enea in Stockholm has launched a Linux Base Station Platform targeting multi-standard Radio Access Networks based on Freescale's next generation mulit-core processors.

More than half of the worlds installed base of macro cell base stations and more than half of the worlds LTE population coverage is powered by Enea software. Building on that momentum, the Enea Linux Base Station Platform is designed to fit Freescales System-on-Chip (SoC) architectures adapting to the expanding standards of LTE and HSPA with support for different standards simultaneously.
For mobile broadband equipment manufacturers, the Enea Linux Base Station Platform provides an integrated software foundation bringing an effective use of resources to the system, including core utilization and performance, thereby reducing the bill-of-material (BOM) cost.
The Enea Linux Base Station Platform provides a high performance implementation for both Macro/Micro cells and Small cells that are based on Freescale QorIQ, StarCore, and QorIQ Qonverge SoC series platforms , says Barry Stern, Baseband Product Line Marketing Manager, Freescale Semiconductor. We work closely together with Enea to create the perfect match for SoCs such as the QorIQ Qonverge B4860 and our latest addition QorIQ Qonverge B4420, targeting Metro/Micro base stations deployment.
The Enea Linux Base Station Platform encompasses the Enea Linux distribution with real-time capabilities and IP transport, IPC communication, plus tools and middleware needed by the 3G and 4G LTE stack and use-case specific application parts to implement a high performance base station/small cell product.
The Yocto-based Linux distribution with customized services and support provides a complete, hardened embedded Linux with networking and telecom focus, while the Light-weight Run-time (LWRT) LWRT extends the real-time capabilities of Linux and allows timing critical applications to execute in Linux user-space. Reduced interrupt latency and deterministic and low-overhead thread scheduling enables applications such as LTE L2 scheduling to run on top of Linux with maximum performance.
