Cavium Networks Inc. , Continuous Computing and Picochip Ltd rolled out a demonstration of a Long Term Evolution (LTE) small cell operating in an end-to-end system with commercially available user equipment (UE) and core network equipment.

The companies' joint exhibit at this year's Femtocells World Summit shows full interoperation between the Picochip PC960x LTE small cell solution, incorporating Trillium LTE protocol stack software from Continuous Computing running on a Cavium OCTEON processor, LTE dongles using Cavium's Odyssey 9000 UE chipsets and an LTE evolved packet core (EPC) supplied by a worldwide leader in networking.

The demonstration follows on from the precedent-setting 3G-interoperability demo involving Cisco, Continuous Computing and Picochip, which took place at Femtocells World Summit 2009. It enables web browsing, voice-over-IP (VoIP) calling and video streaming via the packet core.

Femtocells and picocells (or, more generally, 'small cells') improve mobile voice and data service at business and residential customer premises, in metropolitan hot zones and in sparsely populated rural areas. They are already becoming key components of 3G networks and will play a pivotal role in the deployment of LTE.

Picochip's PC960x is a complete basestation reference design in a?TCA chassis that occupies a physical space of around four liters. It integrates a radio, PHY and Continuous Computing's protocol stacks running on a Cavium OCTEON processor into a complete system, with end-to-end testing and quality. It supports all the standard modes of LTE, with both TD-LTE and FDD variants, and provides a smooth evolution path to future versions of the standard including LTE-Advanced (LTE-A).

The Odyssey 9000 chipsets for LTE are the latest in a series of uniquely designed multiprotocol products from Cavium featuring CAT-3 performance (100Mbps downlink, 50Mbps uplink) for user equipment such as USB dongles, data cards, mobile handsets and tablets/MIDs with low-power, flexibility and price per performance. The Odyssey family also supports all the LTE modes, with 10MHz, 20MHz, TD-LTE and FDD support. The programmable PHY architecture allows the Odyssey 9000 series to support existing LTE bands as well as future bands that are ratified by the 3GPP. This flexibility allows complete freedom of deployment for operators worldwide.

Trillium LTE wireless protocol software addresses LTE Femtocells (Home eNodeB) and pico/macro eNodeBs as well as the Evolved Packet Core (EPC) Mobility Management Entity (MME), Serving Gateway (SWG), Evolved Packet Data Gateway (ePDG), etc. These standards-based Trillium LTE wireless protocols allow customers to rapidly develop LTE infrastructure to compete for early design wins in the dynamic LTE marketplace.
