Ubiquisys is a leading provider of intelligent 3G and LTE (Long-Term Evolution) small-cell (or femtocell) technologies that provides seamless connectivity across mobile networks for service providers and this marks one of the largest European exits in recent months. It follows Mindspeed’s acquisition of picoChip in Bath, NVIDIA’s acquisition of Icera Semiconductor in Bristol and General Dynamics’ acquisition of IP Wireless in Chippenham, all in the wireless sector.
“The acquisition doesn’t just provide Cisco with Ubiquisys’ small cell knowhow; it also gives Cisco experience in working with a broader set of mobile operators,” said Daryl Schoolar, principal analyst at market analyst Ovum. “Ubiquisys provides Cisco much greater market credibility when it comes to 3G and LTE small cells. Cisco will also benefit by having greater control over Ubiquisys’ product development cycle, freeing Cisco from having to rely on the development cycle of third-party partners like IP access.
“Cisco is no stranger to small cells, but that has been primarily through its carrier Wi-Fi efforts,” said Schoolar. “In the licensed spectrum small cell space Cisco has basically been reliant on its femtocell relationship with AT&T. Outside of its work with AT&T, Cisco’s licensed small cell experience has been hard to find. Ubiquisys on the other hand has over 50 customers (vendors and operators) that include Softbank (Japan), SFR (France), and Network Norway. Ubiquisys’ small cell experience greatly bolsters Cisco’s small cell position.
The acquisition of Ubiquisys complements Cisco’s mobility strategy along with the recent acquisitions of BroadHop and Intucell, reinforcing in-house research and development, such as service provider Wi-Fi and licensed radio. These technologies will tie together the mobility architecture that leverages the intelligence of the network from the wireless edge of the network into the wired core.
As carriers around the world increase cellular data capacity to serve the rapidly growing population of smartphone and tablet users, adding small cells is one of the most cost-effective ways to multiply data capacity and make better use of scarce spectrum assets. Ubiquisys’ indoor small cells expertise and its focus on intelligent software for licensed 3G and LTE spectrum, coupled with Cisco’s mobility portfolio and its Wi-Fi expertise, will enable a comprehensive small cell solution to service providers that supports the transition to next generation radio access networks.
The acquisition of Ubiquisys further reinforces Cisco’s commitment to service providers and strengthens Cisco’s mobility capabilities to continue to extend the intelligent mobile network.
Ubiquisys’ product portfolio and team will be integrated into its Small Cell Technology Group led by Partho Mishra.
The company also announced that it has completed the first deployments of its new G7 indoor small cell hotspot, featuring its ActiveCell technology, with two operators in Asia after successful field trials in extremely-challenging public environments.
The Asian G7 deployments have tested extremes of data and signalling traffic, including hotspots experiencing 10,000 users moving in and out every day, with each user typically running HSPA data for over 25% of the time. Indoor public spaces such as cafes, stores, malls and airports are ideal environments for small cells – as operators face rapidly increasing data usage and have abundant fixed broadband available for backhaul.
“We are seeing rapid growth in demand for our public access small cells solutions, particularly in the demanding Asian market,” said Will Franks, CTO and co-founder of Ubiquisys. “These deployment scenarios represent significant technical challenges, but our adaptive technology was designed to run in open-access mode from the outset. We’ve built a substantial base of public access small cell deployments over the past two years and this real-world experience led to the development of ActiveCell technology.”
The Ubiquisys G7 range of 3G/LTE/WiFi public access small cells feature new ActiveCell technology developed on the back of years of experience in deploying small cells in public environments. ActiveCell complements Ubiquisys’ globally proven ActiveRadio and ActiveSON systems for small cell self-management and self-organising clusters. It extends these capabilities to provide carrier grade symbiotic interworking with the macro network, in particular to manage interference effects, whilst retaining the advantages of simple installation and commodity IP backhaul. ActiveCellconsists of groups of software-encapsulated techniques:
* Automatic cell sizing: preserves the target quality of service in hotspots.
* Loaded cell adaptive radio resource management: continuous monitoring of the radio environment even while serving active users.
* Hotspot robustness: ensures the best possible quality of service during high spikes of transient users.
* Edge processing of smartphone signalling to significantly reduce the load on the core network.
The challenges facing public access small cells arise from the sheer volume and unpredictability of traffic, the particular demands of smartphones, and the need to adaptively complement neighbouring cells. Current small cell solutions fail to convince on one of two counts:
* Traditional solutions such as picocells require manual planning and lack adaptive behaviour in operation, which makes them both prohibitively expensive and unsuitable for dense hotspot deployment.
* Small cells created by simply renaming residential femtocell technology are designed for relatively benign closed-mode operation, and are not robust enough to cope with the traffic demands of a public access hotspot environment.
Small cells running Ubiquisys ActiveCell technology combine low operational costs with the ability to deal with the real-world requirements of mobile users in public spaces. They have been field proven to meet the demanding network performance metrics of the macro networks they complement.
