Cisco Systems (NASDAQ:CSCO), aiming to bolster its offerings for mobile networks, is acquiring U.K. company Ubiquisys.

Cisco announced today it plans to buy privately-held Ubiquisys for $310 million in cash. Privately-held Ubiquisys, based in Swindon, U.K., specializes in small-cell technologies. Unlike towers which transmit signals over a wide area, small cells cover a small footprint such as a building.

Mobile providers are offloading more and more traffic onto small cells in an effort to increase their own capacity to serve the growing number of Internet-enabled devices. Ubiquisys software brings intelligence to small cells, giving providers a way to manage and monetize the networks. Cisco said that the Ubiquisys acquisition enables Cisco to offer a more comprehensive offering. Ubiquisys has expertise in indoor small cells and intelligent software for 3G and LTE spectrum. Cisco has a mobility portfolio and Wi-Fi expertise. The company said the Ubiquisys acquisition also complements Cisco’s mobility strategy along with the recent acquisitions of BroadHop and Intucell.

When the Ubiquisys acquisition closes, Ubiquisys employees will be integrated into the Cisco Service Provider Mobility Group, reporting to Partho Mishra, vice president and general manager, Service Provider Small Cell Technology Group. The deal calls for Cisco to pay approximately $310 in cash and retention-based incentives. The acquisition is expected to close during Cisco’s fiscal fourth quarter.

San Jose, Calif.-based Cisco operates its second largest corporate campus in Research Triangle Park.
