Cavium announces TD-LTE support for OCTEON Fusion small cell base station processors

Cavium, Inc. today announced a software stack update that adds support for TD-LTE on its OCTEON Fusion family of SoCs (System-on-Chip). Cavium's TD-LTE software stack option allows small cell manufacturers to deliver both FDD and TDD-enabled products using the same OCTEON Fusion processors.

Cavium offers feature-rich small cell solutions that include manufacturable hardware designs and fully integrated PHY, L2/L3 stack and management software, enabling manufacturers to quickly bring commercial base station products to market. The OCTEON Fusion TD-LTE stack enhancement initially targets 3GPP Release 9, supports up to 128 simultaneous users and 20MHz channel bandwidth. This functionality aligns with the requirements specified for the dense urban deployment market segment.

Spectrum regulators around the world have assigned capacity to TD-LTE, including 50MHz in recent European auctions. In many cases this is re-farming the spectrum that was to be used by WiMAX. Because spectrum is expensive and crowded, this “vacant prime real estate” is a major asset for carriers. TD-LTE has largely been supported by traditional macro cell products until now. The contemporary architecture of small cells, delivering better network efficiency and making best use of spectrum, had not been widely available for TDD.

At the Mobile World Congress conference in February, Cavium announced UniFiRAN, an end-to-end software solution that will enable a seamless RAN (Radio Access Network) architecture in 3G and 4G networks. The scalable software running on Cavium's OCTEON and OCTEON Fusion processors allows a unified set of applications to run across platforms ranging from 3G/4G small cells to micro and macro cells, to Cloud RAN configurations.
