RadiSys closes acquisition of Continuous Computing

RadiSys has closed its acquisition of Continuous Computing. Continuous Computing, now a wholly-owned subsidiary of RadiSys, develops communications systems consisting of highly integrated ATCA platforms and Trillium protocol software coupled with software Professional Services to complement their full solution offering. Their key customer applications include 3G and 4G wireless infrastructure, small cell base stations, traffic management, internet offload and network security.

Picochip and InterDigital demo converged gateway with integrated 3G femtocell and Wi-Fi

Picochip and InterDigital demonstrated InterDigital’s converged gateway technology integrated on Picochip’s 3G femtocell with Wi-Fi at Femtocells World Summit in London. The demo system delivers novel offloading solutions by intelligently managing data flows across multiple physical transports or networks. Only in the last few years have network operators started to embrace cellular and Wi-Fi as complementary technologies –  by increasing data volumes through offloading cellular users onto Wi-Fi. InterDigital’s converged gateway solution uses advanced operator-controlled policies to combine, split, or handover data streams based on contextual parameters, such as channel conditions, content, user preferences, subscription plans, etc.  

Picochip powers SK Telecom’s femtocell-based data-offload deployment

Picochip has been chosen to supply the technology for the second wave of femtocell access points from Contela, used by Korea’s SK Telecom (SKT) for data offload. Building on the success of Contela’s first-generation data-only product, also based on Picochip technology, the new 2FA combines a 16-user ‘dual-carrier’ HSPA+ femtocell with Wi-Fi in an integrated access point. SKT will deploy the 2FA in high-traffic areas such as cafés, shopping malls, train stations, offices and apartment blocks.

Femtocells to the fore at the Fira – Mobile World Congress 2011

This year more than ever before, femtocells were one of the key technology stories at Mobile World Congress. But far from just conventional residential femtocells, larger enterprise and 'metro' femtocells were much in evidence this time, and the distinction between these and microcells or picocells is now largely based on which platform they have been developed on rather than their physical size or capacity. At the opposite end of the spectrum, a residential femtocell can now be realised in a USB dongle form factor.

Roke Manor and picoChip femtocell has 40km range

Roke Manor Research has developed a 3G femtocell reference design with wide area coverage up to a 40km range, using picoChip's technology as the development platform. As well as giving coverage of an area more than 40,000 times the size of that traditionally offered by femtocells, itt is also the first design of its type to support full mobility at speeds of up to 120km/hour. Roke says that this dramatic improvement in range has been achieved by modifying the physical layer code.

Deltenna launches wireless broadband enabler for 2Mb/s rural service delivery

A device to deliver broadband to rural areas that are distant from a fixed telephone exchange has been launched today by Chippenham, UK, based Deltenna. The WiBE (Wireless Broadband Enabler) creates a 2Mb/s Wi-Fi hotspot connected to the 3G mobile network, even in many places where a 3G mobile phone would be unable register a signal.

Enhanced version of WeFi software launched for locating Wi-Fi hotspots

With the anticipated growth in importance of Wi-Fi as a means of offloading data traffic from overburdened cellular networks, the means of locating and automatically connecting to suitable hotspots is becoming a priority. Now WeFi, a company that has already created a database of over 56 million Wi-Fi access points worldwide, has launched an updated version of its free connection software for PC and Android mobile phones. The software locates and categorises available Wi-Fi hotspots, with user-friendly mapping of all access points relative to a specific street address.
