Qualcomm enters small cell LTEfray with neighborhood access SoC

At the Small Cell World Summit in London, U.K. this week, Qualcomm Technologies, Inc.   took the wraps off its FSM90xx system-on-chip (SoC) for neighborhood and small and medium business (SMB) small cells. The company expects to begin sampling the new SoC this summer.

According to Dan Rabinovitsj, senior vice president, Qualcomm Atheros, Inc., the FSM90xx is designed to provide specific features so that original equipment manufacturers (OEMs) can deliver the right form factor and application for the target use cases.

He said it leverages LTE functionality from the FSM99xx, which was announced last year and is commercially available now. “With access points (APs) based on this new small cell SoC, mobile operators, cable multiple systems operators (MSOs) and businesses can expand network capacity and ensure superior end-user mobile experiences cost effectively,” he said.

Part of this SoC package is Qualcomm's Internet Processor (IPQ), which features a powerful packet processing engine that scales to handle a variety of networking functions, including Wi-Fi and LTE. Rabinovitsj said hardware accelerators have been built into the chipset to speed up data processing for both radio technologies, which allows for significant bill of materials savings, both from a hardware perspective and in terms of reducing overall development time needed for system integration.

To reduce interference and maintain high service quality for dense SMB and neighborhood small cell deployments, the FSM90xx integrates advanced self-organizing networks (SON) techniques through UltraSON software. He said the FSM90xx can be paired with Qualcomm's RFICs (FTR8xxx) to support all LTE bands worldwide and maintains compatibility with the FSM99xx to further ease and speed OEM product development across both product lines.

The FSM90xx is software compatible with the FSM99xx to allow OEMs to expand their product portfolios by leveraging their software investments in FSM99xx. The FSM90xx also benefits from the mature LTE PHY, digital pre-distortion, low power consumption and other differentiating features of FSM99xx.
