Cavium and Quortus enable LTE RAN and EPC on single chip for portable applications

Quortus evolved packet core embedded onto a Cavium OCTEON Fusion processor turns a small cell into a fully functional, highly portable, standalone mobile network which can operate without any connection to a remote centralised core – ideal for military and public safety organisations

Cavium and Quortus enable LTE RAN and EPC on single chip for portable applications

Semiconductor provider Cavium and mobile network core specialist Quortus, announced a partnership today (22 July 2014) to embed Quortus’ software evolved packet core (EPC) on Cavium’s OCTEON Fusion family of system-on-chip (SoC) processors for small cell base stations.

The combination of Cavium’s OCTEON Fusion processors, LTE stack software and low power, low cost eNodeB designs with Quortus’ highly efficient, fully featured EPC software  turns small cells into extremely-portable, standalone rapidly-deployable mobile networks for site-specific uses such as public safety, emergency services and military applications.

This allows the private network to operate without any connection to a remote centralised core enabling new deployment paradigms.

The OCTEON Fusion family of SoCs is the industry’s most powerful small cell ‘base station-on-a-chip’ product line, providing hardware acceleration specifically designed for LTE and 3G small cells, Cavium claims. The company’s field-proven small cell solutions include complete software implementations (PHY + stack) and manufacturable hardware designs.

Quortus’ software EPC technology distills the functionality of a core network into an application which can be installed on SoCs, commodity hardware or in the cloud.

It not only reduces the cost of network deployments, but brings a level of flexibility that allows core intelligence to be placed where it is needed most, including the network edge. It is deployment-proven in a range of settings including enterprises and remote locations, on both public and private networks.

By embedding Quortus’ EPC on the OCTEON Fusion processor, the entire functionality of a mobile network can be held on the same chip; this means that a single small cell can become a highly portable mobile network.

Furthermore, placing the radio and core layer on the same chip reduces the complexity of interaction between both layers, enabling the implementation of advanced functionality such as meshing, macro mobility and satellite backhaul optimisation features in a more efficient way.

Mobile network solution for public safety and military
This enhanced portability - with no loss of functionality - provides a solution tailored to the needs of the public safety and military markets. Often for first responders, existing communications and power infrastructure can be insufficient or comprised.

In this case an easily-deployed, self-contained network is called for. The combination of Cavium’s OCTEON Fusion with Quortus’ EPC makes such a solution a reality; one that boasts the portability and flexibility to be rapidly deployed wherever it is needed, even at the network edge.

“Cavium has demonstrated its leadership in LTE small cell technology through volume commercial deployments of OCTEON Fusion-based eNodeBs worldwide,” said Raj Singh, general manager of Cavium’s Wireless Broadband Group.  

“We are focused on offering deployment-ready hardware and software solutions to our OEM and ODM customers.  By partnering with Quortus we are able to leverage their core network expertise to offer a complete mobile network solution - radio and core - all in one box.”

Andy Odgers, CEO, Quortus, said: “For emergency services and the military, being able to easily access the communications tools they need is paramount; this makes portability and flexibility a must.”

“The OCTEON Fusion provides significant processing capability with very low-power usage. When combined with our EPC it can support a full mobile network in a package small enough to hold in the palm of your hand. We look forward to a continued relationship with Cavium that will see us provide elegant and efficient small cell solutions to this market,” concluded Odgers.
