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 world's installed base of macro cell
base stations and more than half of the world's LTE population coverage
is powered by Enea software. Building on that momentum, the Enea Linux
Base Station Platform is designed to fit Freescale's 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.
Enea's Packet Acceleration Foundation (PAX) provides IP Transport
Ready-to-use building blocks for base station communication with
controller and core network. A user space implementation that uses
Freescale QorIQ and Qonverge hardware functions and accelerators
provides scalability and performance and there is a low-overhead
user-extensible foundation with support for tracing and profiling.
The LINX High performance and scalable messaging-based IPC is used for
intra- and inter- core control and data plane messaging within the base
station main unit and with the radio unit, while the Hypervisor provides
specialized systems virtualization for high-performance, deterministic
It also includes a multicore DSP Layer 1 (PHY) run-time, communication,
and Linux DSP management foundation for multi-standard macro and small
cell implementations and middleware for simplifying the development of
telecom-grade distributed systems by providing frameworks for messaging,
debug and trace, management, and high availability, including
in-service software upgrade.
The Enea Linux Base Station Platform comes with a customizable range of
services and support, maintenance and continued development of the
integrated product. Upgrades and updates providing new versions of Enea
products and open source software in the integrated product are made
according to customer needs.
