Ubiquisys has taken its total venture capital fundraising to $81 million (£51.7 million) and attracted two new investors.
Swindon-based mobile technology business Ubiquisys has raised $19 million in an ‘oversubscribed’ funding round led by new backers Mobile Internet Capital and Nissay Capital.
The two Japanese venture capital firms join the likes of Accel Partners, Advent Venture Partners and Atlas Venture as institutional supporters of the company.
The new capital raised will be used to speed up the delivery of its tri-mode 3G/LTE/WiFi small cell hotspots.
Ubiquisys also produces femtocells, devices that allow multiple mobile phone connections in a home or business setting, usually in areas where coverage may not otherwise be available.
Small cells, effectively mini cell towers, can provide coverage as localised as a single home, allowing the same frequencies to be reused and allow traffic to be shifted off congested airwaves.
Ubiquisys’ last fundraising was in September 2010 when three Taiwanese technology firms led a $5 million investment in the business as part of a second close of its Series D round.
Preceding that, Ubiquisys’ $12 million Series A round was closed in September 2006. Further rounds worth $25 million (July 2007), $11 million (August 2008) and $9 million first close (July 2010) saw investment from worldwide venture capital firms.
Chris Gilbert, CEO of Ubiquisys, comments, ‘Public access small cells require extremely high performance, resilience and fully automatic, adaptive capabilities.
‘We remain uniquely placed to benefit from the ongoing exceptional growth in the small cell market and welcome this investment to help us meet this demand.’
