Swindon-based Ubiquisys was founded in 2004, and is currently backed by Advent Venture Partners, Accel Partners and Atlas Venture.

The latest funding round, which was led by 5 Continents Consulting Group, involved the company’s existing investors as well as the Japanese venture capital firm Yasuda Enterprise Development as a new investor.

Ubiquisys produces femtocells, which are devices that allow multiple mobile phones connections in a home or business setting, usually in areas where coverage may not otherwise be available.

The company plans to use the capital to target femtocells in new market segments such as indoor hotspots, the metro and rural areas.

Chris Gilbert, CEO Ubiquisys, says: ‘The femtocell market is ramping faster than we envisaged, and the advent of the free model, pioneered by SoftBank and enabled by Ubiquisys, will only increase that momentum.’

In the past twelve months Ubiquisys has met a number of its strategic milestones, including launching Ubiquisys femtocells with mobile networks SFR in France, and SoftBank in Japan.
