SiBEAM was founded to commercialize pioneering millimeter wave wireless technology developed at the labs of University of California, Berkeley.

[14][15] On January 5, 2015 Silicon Image Re-Launched SiBEAM, Inc. as a wholly owned subsidiary to drive market development of millimeter-wave products, technologies and solutions[buzzword] [16] On March 15, 2015, Silicon Image was acquired by Lattice Semiconductor in an all-cash acquisition, valued at approximately $606.6 million (or approximately $466.6 million on an enterprise value basis).

On July 18, 2018 Lattice Semiconductor announced that they "will discontinue its millimeter wave business, which is expected to result in approximately $25 million of primarily non-cash restructuring and impairment charges in the second quarter of 2018, and an annualized reduction in operating expenses of approximately $13 million.

"[18] When SiBeam was active the company focused on products using the 60Ghz-Range, including the low-range "Snap" family used in wireless connectors which were thought to be able to replace USB ports,[19] chips transmitting video data to enable wireless monitors,[20] as well as modules supporting transmission ranges up to 300m, like the 2017 launched MOD65412.

[21] SiBEAM's WirelessHD protcocol was used in notebooks, like the Alienware M17x R3 or the G73JW[22] and is still an alternative to video transmissions over the 5GHz WiFi band.
