Sooktha collaborates with Freescale to demonstrate LTE access network virtualization on the Freescale vAccess Platform

Bangalore – (December 3, 2015) — Sooktha, an advanced wireless access solutions company, today announced that it has demonstrated a solution for radio access network centralization and virtualization using its LTE Advanced Smart Base Station (SBS) solution on the Freescale® vAccess platform. The vAccess system powered by the Sooktha LTE Advanced SBS software was demonstrated by Freescale at the Mobile World Congress 2015 at Barcelona, Spain earlier this year.

Centralization and virtualization have the potential to significantly change the way networks are deployed. Today’s wireless base station nodes are very proprietary hardware and software platforms. With 5G convergence across wireless, wireline and IoT access methods, a modular, portable and standardized approach to implementing access network software is important. This is a critical requirement towards leveraging the full power of SDN and NFV in the access network.

The Sooktha SBS is a full base station implementation that can be easily spilt at different points to support different centralization and virtualization approaches. The support for a mix of FDD and TDD carriers, carrier aggregation, centralization, virtualization, VoLTE, and different traffic types – make it a powerful solution.

The Freescale vAccess is a combined Hardware / Software platform, which showcases a functional virtualized network system.

The vAccess platform effectively demonstrates:

  • How to design and build modular, flexibly deployable software with standardized interfaces and deployment models
  • Interaction between off-the-shelf L1 (Physical Layer/Baseband) and higher layer components from different vendors
  • How to implement virtualization with minimal overheads

“We have been able to quickly deploy our SBS LTE eNodeB on the Freescale vAccess platform, communicating with remote radio nodes using standard network interfaces, and with SDN based orchestration”, says Balaji Rangaswamy, CEO at Sooktha. ”This demonstrates the full power of the modularity and flexibility of our SBS solution that allow it to significantly accelerate the development of software-defined and virtualized access solutions”.

Wim Rouwet, Senior Systems Architect for Freescale says: “This type of technology is really a starting point for what 5G network deployments will look like, where you have to provide a scalable solution across a variety of nodes, ranging from low-end to high-end, virtualized or not.”

The collaboration between the two companies is expected to evolve to productize components from this platform, as well as to evolve the hardware and software in the areas of functionality, performance and scalability.

Sooktha LTE Advanced Smart Base Station Solution Fortifies Spirent’s LTE Test Offering

Sunnyvale, Calif. – (September 9, 2015) — Spirent Communications, the leader in testing networks, services and devices, and Sooktha, an advanced wireless access solutions company, announced today that Spirent implemented Sooktha’s software in its Wireless Test Station (WTS122) solution for IMS, RCS and VoLTE testing capability. The WTS122 is the first solution of its kind to enable VoLTE device-to-device mobile testing in one unit. This benchtop network emulator utilizes modular, programmable, and scalable Layer 2 stack from Sooktha’s LTE Advanced Smart Base Station (SBS) solution.

The WTS122 is at the heart of the Spirent Elevate Test Framework and tests VoLTE functionality, IMS/RCS conformance, device-to-device interoperability, as well as VoLTE E911 and Voice over Wi-Fi capability. While IMS, VoLTE, and RCS testing focus on application layer functions, these critical areas require support for Layer 2. VoLTE user experience depends on quality of service (QoS) based dedicated bearer management, semi-persistent scheduling (SPS), and robust header compression (RoHC). These LTE radio access network (RAN) features are available on the WTS122 and supported by Sooktha’s Layer 2 stack.

“The advent of IMS, RCS, and VoLTE is bringing about a new wave of services that require implementation of new test methodologies,” said Clarke Ryan, director of engineering at Spirent Communications. “We developed the Spirent Elevate framework to provide a flexible and open platform which allows us to quickly and efficiently diversify our test capabilities to suit our customers’ needs. With this partnership, we were able to utilize Sooktha’s customization, ASP support, rich software diagnostics, and stable LTE protocol stacks for the timely launch of Spirent Elevate Test Framework.”

“The Spirent WTS122 solution powered by Sooktha SBS software demonstrates the industry leading feature set and the simplicity, scalability, and extensibility of the Sooktha software,” said Balaji Rangaswamy, CEO at Sooktha. “It also demonstrates our commitment to accelerating the deployment of next generation wireless technologies by developing solutions for both test and measurement and infrastructure segments.”
