Continuous Computing extends Trillium LTE portfolio with TDD eNodeB support and suite of advanced LTE MAC schedulers

SAN DIEGO, USA: Continuous Computing, the global provider of hardware and software solutions that address the mobile broadband capacity challenge, announced the general availability of its upgraded Trillium Long Term Evolution (LTE) eNodeB protocol software, which now includes support for the Time Division Duplex (TDD) variant of LTE, known as TD-LTE.

Concurrently, the company is now offering its Trillium Advanced LTE Media Access Control (MAC) Schedulers suite, a set of six optimized schedulers, as well as an upgrade to the MAC scheduler interface, which helps network equipment providers (NEPs) to meet growing scalability requirements by creating their own scheduler implementations and running MAC and the MAC scheduler as independent execution modules.

By complementing its Frequency Division Duplex (FDD) LTE stacks with TDD support, Continuous Computing has expanded market opportunities for NEPs while facilitating WiMAX-to-LTE product evolution.

Amidst growing support for both the TDD and FDD variants of LTE, TD-LTE enables WiMAX companies which are adding LTE to their portfolios to speed up their development. Unlike in the 3G market where TDD variants of the WCDMA standard are being deployed only in certain regions, TD-LTE is expected to have broad applicability due to the availability of unpaired spectrum around the globe. While FDD requires paired spectrum (one carrier for downlink and one for uplink), TDD employs unpaired or shared spectrum using time slots to manage interference.

“Continuous Computing'’s off-the-shelf Trillium TD-LTE solution gave FiberHome the flexibility to focus on other aspects of our implementation,” Mr. Zhu Yuxia, General Manager of Beijing Northern FiberHome. “The quality and portability that Trillium software offers allowed us to greatly improve our time-to-market.”

One of the key break-throughs in achieving LTE’s promised data rate performance is the MAC scheduler, which permits efficient and optimal allocation of resources on the air interface. Resources are scheduled once per millisecond and on a per-user basis, making this function both processor-intensive and time-restrictive.

By providing six proven implementations of different scheduling algorithms and allowing NEPs to define their own unique algorithms, Continuous Computing is accelerating time-to-market and enabling product differentiation. De-coupling the LTE MAC and MAC scheduler functions also enables NEPs to scale the scheduler independently as the number of users increase.

“With 13 LTE design wins and counting, Continuous Computing is focused on maintaining its leadership position in LTE through consistent investment in product evolution, including performance optimization, compliance upgrades and feature enhancements,” said Manish Singh, VP Product Line Management at Continuous Computing. “This release of upgrades to our LTE eNodeB stacks is a critical next step in our strategy to solve the tough challenges of femto, pico, micro and macro eNodeBs.”

The enhanced Trillium LTE eNodeB Software and Advanced MAC Scheduler suite is available now.
