Ubicom, a Sunnyvale, Calif. company that provides communications processor and software technology to help connect devices in the home over high-speed networks, said it has raised a $18 million fourth round of funding.

The round was led by Lehman Brothers Venture Partners and Samsung Venture Investment Corporation and included other existing investors.

Brian Melton, a partner in Lehman Brothers Venture Partners, will join the board of directors, the company said.

Here’s a self-description of the company:

Ubicom develops communications and media processor and software platforms that address the unique demands of real-time interactive applications and multimedia content delivery in the digital home. The company provides optimized system-level solutions to OEMs for a wide range of products including wireless routers, access points, bridges, VoIP gateways, connected digital photo frames, streaming media devices, and other network devices. Ubicom’s unique multithreaded processor design, real-time operating system, and application-level solutions combine to ensure a high-quality user experience with unprecedented ease of use.

The company has been around for 12 years, and raised nearly $77 million before it struggled in 2004, and was forced to restart with fresh investment. It has since raised $59 million from investors that include August Capital, Cisco, Dell Ventures, InveStar Capital, Jatotech Ventures, Levensohn Venture Partners, Vertex Management and Walden International, according to VentureWire.
