RAD Data Communications has unveiled its new Airmux-400 broadband wireless multiplexer, which is said to deliver robust carrier-class, high capacity, extended range voice and data.

The Airmux-400 is a full duplex, 50-Mbps capacity multi point-to-point broadband wireless transmission device, which will transport both legacy TDM and next generation Ethernet services over licence-free 2.3 to 2.5 GHz and 4.9 to 5.9 GHz bands.

"The Airmux-400 is designed to connect 'data hungry applications' such as cellular or WiMAX base stations to controllers, meeting the requirements of backhauling applications by transporting Ethernet traffic for maintenance and control," explains Toby Korall, Senior Product Line Manager at RAD Data Communications. "In addition, Wireless Internet Service Providers (WISPs) can use the Airmux-400 to backhaul their traffic from the point of presence (POP) to the network operation centre to achieve higher capacity and can offer bundled connectivity," Korall adds. "The Airmux-400 also provides broadband Ethernet and leased line services to large enterprises and is ideal for networks spanning multiple sites that require transparent LAN connectivity across their campuses."

RAD's Airmux multiplexers consist of an outdoor unit and an indoor unit with redundant DC power supplies. The outdoor unit is suitable for mast or wall installation. An optional external antenna is said to guarantee a transmission range of up to 120 kilometers.

Hub Site Synchronization (HSS) ensures simultaneous, multi point-to-point data transmission for all collocated radios by eliminating the interference that otherwise occurs when different outdoor units transmit and receive from the same site. HSS, which supports up to 16 collocated units, enables a complex radio environment of mixed services.

Built on advanced MIMO and OFDM technologies, the Airmux-400 ensures high robustness of the air interface even under interference and harsh conditions. Data transmitted over the air interface is encrypted using Advanced Encryption System (AES) with a 128-bit encryption key. The device adaptively changes the modulation according to air conditions, targeting maximum rate while maintaining link stability. The rate drops temporarily after encountering interference, then automatically returns to the highest possible rate. When the link quality is out of limits, the Airmux-400 automatically searches for a clear channel within a pre-selected list of frequencies.

The Femto Forum, the independent industry and operator association that supports femtocell deployment worldwide, has announced the results of its femtocell radio study.  The study found that femtocells have the potential to deliver an order of magnitude more capacity than the macro network alone when used in dense deployments, even when occupying the same radio channel as the macrocells. It also identified numerous technological solutions that mitigate potential interference with the macro network to remove barriers to wide-scale deployment and maximize the capacity benefits.

The research assessed the impact of femtocells on a mobile network in a wide
range of deployment scenarios in order to explore co-existence issues
including interference.

The study looked at both femtocells using a separate carrier to the
surrounding macro network and those using the same carrier - which pose the
greatest interference challenge, but also the greatest opportunity for
increased spectrum efficiency.

Although femtocells using a separate carrier were demonstrated to provide a
simple means to essentially eliminate interference, many 3G operators do not
have enough spectrum for this to be practical. The Femto Forum therefore
identified technological solutions that mitigate the potential interference
where femtocells share the same carrier as the macro network. These methods
are already being developed for pre-standard femtocell solutions, and Femto
Forum members are working to bring them within the standards framework.

The key solutions are:

.       Adaptive Pilot Power Control, whereby the femtocell dynamically
adjusts its transmit power in response to the current level of signals from
surrounding cells and the desired coverage area.

.       Extended Tests for Dynamic Range, to ensure that femtocell designs
are able to operate reliably even in the presence of nearby high power
mobile phones connected to the macro network (this test has already been
incorporated into the latest 3GPP Release 8 25.104 specification).

.       Uplink power capping of the mobile phone when operating in the
femtocell environment, ensuring that, even in difficult radio conditions,
the phone hands-off to the macro network before its transmit power increases
to the point where macro noise rise is a problem.

.       Dynamic receiver gain management in the femtocell (Automatic Gain
Control or adaptive attenuation), to ensure that femtocells can offer good
service to both near and far mobile phones without unnecessarily increasing
the phone transmit power, therefore keeping the noise rise to a minimum.

This particular study relates to WCDMA, but the Femto Forum represents the
full range of radio standards and similar studies are underway for other air
interfaces.

"At a time when mobile operators are seeing data usage rocket, femtocells
offer an economic and effective way to deal with demand," said Professor
Simon Saunders, the Femto Forum's Chairman. "By utilizing the identified
interference management techniques it has been shown that femtocells offer
operators an effective method to increase capacity and coverage within their
existing networks through dense cell deployments."

Colibria, a provider of messaging and social networking solutions, has today announced the availability of a new Social Network Gateway, to support the growing consumer demand to be constantly connected to their social networks whilst on the move.

The new solution is said to provide a simple enhancement to an existing mobile IM client that enables the user to access the plethora of social networks from within a single application on their mobile handset. 

The Social Network Gateway will also integrate with a mobile phone's contact list to provide the user with complete visibility of the ‘social communication' of each individual within their contact list. The solution also allows mobile users to control how and when they are updated on the activity within their social network, enabling them to simply and easily update their social network by posting pictures, comment and content whilst on the move.

Icomera, a provider of cellular broadband gateways, and UK bus and coach operator FirstGroup, have announced the availability of free Wi-Fi internet access on the RailAir coach service linking Heathrow Airport with Reading in the heart of the UK's technology corridor.

The fleet of RailAir coaches has been equipped with the Icomera Moovbox M Series mobile broadband gateway that offers internet access to passengers throughout the 50-minute journey at actual download speeds in excess of two megabits per second. The Moovbox M Series also provides GPS-based vehicle location enabling FirstGroup to track their vehicles in real time. RailAir is a non-stop service operated by First Berkshire with departures from Reading for Heathrow terminals up to every twenty minutes. FirstGroup has approximately 9,000 buses operating in 40 towns and cities across the UK, carrying 3 million passengers every day.

"Technology such as the Icomera Moovbox offers real opportunities for First Berkshire and our passengers," said Chris Dexter, Chief Operating Officer for First in Berkshire. "We carry a high volume of business travellers who appreciate the ability to get online for free during the trip to and from Heathrow Airport. On-board Wi-Fi is a value-add that draws more customers and differentiates our service from those of our competitors. At the same time, the GPS functionality of the Moovbox means we know exactly where our vehicles are at any specific moment, allowing us to monitor our schedule adherence more effectively, and enabling Service Controllers to make decisions with confidence when delays on the motorway affect service."

According to Icomera, usage of Wi-Fi hotspots on public transport has seen significant growth during 2008. Icomera reported over 3.7 million sessions by over one million passengers in the twelve months to October 31st on its in-vehicle Moovbox systems worldwide, a 272% increase over the period.

"Given the passenger demographic, airport bus and coach routes are a natural choice for Wi-Fi services," said Dave Palmer, Senior Vice President of Worldwide Sales at Icomera. "Business passengers can get online at no cost and make the best use of their time. More importantly free Wi-Fi is the preferred way to connect while travelling abroad as it avoids high international 3G data roaming charges."

The RailAir deployment is part of a Wi-Fi initiative currently underway at First based on Icomera's Moovbox technology. First Berkshire is in the process of fitting Icomera mobile broadband gateways on the Green Line service that runs between Royal Windsor and Victoria Coach Station in Central London. The Icomera Moovbox has also been deployed in South Wales by First Cymru on the Shuttle100 commuter coach service between Cardiff and Swansea.

The UMTS900 Global Status Information Paper published by GSA, the Global mobile Suppliers Association, has confirmed 67 UMTS900 devices have been launched in the market by 14 suppliers. This compares with 9 UMTS900 devices identified in a similar survey by GSA in June 2008 and confirms an increase over seven-fold. The UMTS900 Global Status information paper details UMTS900 network deployments, launches, trials, regulatory developments worldwide, and devices availability.

UMTS900 devices support HSPA data speeds comparable with 2100 MHz devices. The research by GSA confirms that the 900/2100MHz combination for WCDMA-HSPA is becoming much more commonplace.

The research, together with related activities by GSA, is said to confirm the strong momentum for deploying UMTS900, which helps operators to extend voice, data and mobile broadband services coverage by leveraging the advantages of lower frequencies. While the majority of today's HSPA mobile broadband networks operate in the 2100 MHz band, the use of lower frequencies, such as 900 MHz, provides a much larger coverage area. This translates to a significant reduction in the number of cell sites needed to cover rural and suburban areas. Another benefit is improved voice quality.

GSA recently published an operator case study on Elisa, Finland, which concluded that 3G coverage with UMTS900 can save 50 to 70% of mobile network costs when compared to deployments in the 2100 MHz band, including both CAPEX and OPEX. Similar cost and coverage benefits also apply to UMTS system deployments in other lower frequency bands, such as 850 MHz.

GSA has also confirmed that six network operators have commercially launched mobile broadband services using UMTS900: Elisa (Finland), Elisa (Estonia), Optus (Australia), AIS (Thailand), Vodafone (New Zealand), and now DNA (Finland), with the majority being part of a dual-band HSPA (i.e. 900/2100 MHz) system. Several more trials and network deployments of UMTS900 systems are on-going worldwide.

Cellcrypt, a supplier of voice security solutions, has announced the release of Cellcrypt Mobile v4.0 which provides end-to-end voice encryption on Nokia Smartphones and, for the first time, on a range of Windows Mobile devices.

Nokia Siemens Networks researchers have successfully demonstrated Relaying technology proposed for LTE-Advanced, enabling an 'exceptional end-user experience delivered consistently across the network'.

Completed in Nokia Siemens Networks research facilities in Germany, the demonstration is said to illustrate how advances to Relaying technology can further improve the quality and coverage consistency of a network at the cell edge - where users are furthest from the mobile broadband base station.

According to NSN, relaying technology, which can also be integrated in normal base station platforms, is cost efficient and easy to deploy as it does not require additional backhaul, says NSN. The demonstration of LTE Advanced means operators can plan their LTE network investments knowing that the already best-in-class LTE radio performance, including cell edge data rates, can be further improved and that the technological development path for the next stage of LTE is secure and future-proof.

Stephan Scholz, Chief Technology Officer of Nokia Siemens Networks, said: "Demonstrating improved cell edge and indoor-user data rates is an important milestone for coverage scenarios. It further strengthens the position of LTE as the major mobile broadband technology. Consumers will enjoy an even richer user experience thanks to higher throughput everywhere in the cell, while operators will be able to deploy their networks in a more flexible and cost efficient way.

"LTE Advanced is the next step in the evolutionary development of LTE technology. Nokia Siemens Networks performs extensive research activities for LTE-Advanced in developing this important technology which will be decisive to our customers in the future."

Performance enhancements have been achieved by combining an LTE system supporting a 2x2 MIMO (Multiple Input Multiple Output) antenna system, and a Relay station. The Relaying operates in-band, which means that the relay stations inserted in the network do not need an external data backhaul. They are connected to the nearest base stations by using radio resources within the operating frequency band of the base station itself. Towards the terminal they are base stations and offer the full functionality of LTE.

LTE-Advanced is currently being studied by 3GPP for Release 10 and will be submitted towards ITU-R as the 3GPP Radio Interface Technology proposal. The improved cell coverage and system fairness - meaning offering higher user data rates for and fair treatment of users distant from the base station - will allow operators to utilise existing LTE network infrastructure and still meet growing bandwidth demands.

The demonstration has been realised by using an intelligent demo relay node embedded in a test network forming a FDD in-band self-backhauling solution for coverage enhancements. With this demonstration the performance at the cell edge could be increased up to 50% of the peak throughput. Nokia Siemens Networks is the forerunner in LTE. In 2006 the company was the first to demonstrate LTE technology with data speeds in the 160Mb/s range as well as a successful handover between LTE and HSPA, and continued breaking records in 2007 by demonstrating a multiuser field trial in an urban environment with peak data rates of 173 Mb/s.

Starhome, a provider of roaming services and converged solutions, is part of a consortium that has completed integration of an "extended home" remote control platform.

As part of the Celtic EnComPAs2 (Enabling Community Communications - Platforms and Applications phase 2) project, Starhome is developing a concept for mobile services for the "extended home." This environment includes the home, the car and other remote sites acting as a virtual home environment, enabling remote access to home content such as videos, photos, music and other media.

Celtic is a European R&D programme that initiates and runs privately and publicly funded Information and Communication Technology (ICT)/telecommunications R&D projects. EnComPAs2 is being led by Telefonica I+D. Consortium members include Acciona Infraestructuras and Ikerlan from Spain, and TNO ICT from the Netherlands.

The Starhome concept is said to link mobile networks and home networks for the first time, enabling mobile operators to provide value added services for the home. The implementation combines the Next Generation Network architecture, which consists of IP Multimedia Subsystem (IMS), and a home residential gateway. Starhome is providing the IMS connectivity for the project, including mobile services such as smart call routing between GSM/UMTS and Wi-Fi, depending on the user location.

Shai Ophir, Starhome's Technology Specialist, believes that Starhome's concept has the potential to revolutionise the convergence market. "Completing integration was an important step for Starhome and our consortium partners in the development of this cutting-edge technology. This project has the potential to significantly enhance the mobile landscape by both improving the home service environment and extending its reach.

"One exciting prototype being developed by Starhome for this project will converge voice and messaging between car and mobile. The mobile network will capture an SMS being sent to a mobile subscriber who is driving, for example, and will convert the message into a voice call in order to increase driving safety," said Ophir.

Mobile Broadband Network Limited (MBNL), the 50:50 joint venture formed by 3UK and T-Mobile UK to manage the integration of both operators' 3G radio access networks (RAN), has awarded Ericsson a four-year managed services contract for the operation and maintenance of the consolidated network.

T-Mobile and 3 formed their infrastructure sharing agreement in January 2008 with the aim of creating the UK's most extensive 3G network by 2010. The network collaboration will deliver close to complete nationwide population coverage for 3G services and 'significantly improve' in-building signal strength. The agreement will also deliver substantial cost savings as well as environmental benefits, including the decommissioning of an estimated 5,000 cell sites.

Under the terms of the agreement, Ericsson has responsibility for the operation and performance management of both parent companies' 3G networks and T-Mobile's 2G RAN infrastructure. The four year contract will enable MBNL to control operational expenses and deliver high service levels at a time when the 3G network consolidation is moving into the mass deployment phase.

The first integrated cell site was commissioned in early February 2008. Since then MBNL has concluded a pilot in the Leeds and Bradford area which successfully validated the network sharing technology and is now engaged in consolidating the radio access networks across the UK.

Around 80 employees from T-Mobile have been transferred to Ericsson, further strengthening its existing UK managed services capability. In the UK, Ericsson holds separate managed services contracts with T-Mobile and 3.

Emin Gurdenli, Chief Technology Officer for T-Mobile UK, says: "The appointment of Ericsson is another significant step towards realizing our commitment to create and operate the UK's most extensive 3G network. Partnering with a proven and progressive services organization reinforces our intent to deliver superior, high-speed mobile data services to customers across the UK."

Mats Granryd, Managing Director, Ericsson UK, says: "We are delighted and proud to be given the responsibility of operating the radio access network for MBNL. This is an extremely exciting and bold project and we are entirely committed to playing our part in achieving success for MBNL's parent companies."

Graham Baxter, CTO, 3 UK, says: "The deployment of our consolidated mobile broadband network is advancing rapidly. Having Ericsson as a trusted partner operating the access network will be an important contribution to our overall goals of providing a reliable and high performance service."

The contract with Ericsson is the latest of a number of key supplier agreements awarded by MBNL in recent months for the provision of 3G radio network infrastructure and a five-year managed service contract for the supply of high-speed Ethernet connections to 7,500 cell sites.
