The R&S SMU200A high-end vector signal generator from Rohde & Schwarz is now available with an option that supports realtime processing of feedback information in LTE base station receiver tests.

Equipped with the R&S SMU-K69 option, the signal generator processes HARQ feedback as well as uplink timing adjustment commands from the base station, and then adapts the LTE signal dynamically in line with the 3GPP TS 36.141 test specification. These tests previously required special test user equipment (UE) and fading simulators, but Rohde & Schwarz now offers a one-box solution to replace complex test setups - the R&S SMU200A combines RF signal generation and fading simulation with realtime feedback processing capability all in a single instrument.

The 3GPP TS 36.141 conformance test specification defines a range of demanding closed-loop performance tests to characterize the performance of LTE base station receivers. A base station must be able to dynamically check the transmission of channel-coded data packets. This means that during testing, a signal generator not only needs to send RF signals with the correct channel coding in compliance with the LTE standard, but must also be able to respond to the feedback information from the base station. With the new R&S SMU K69 option (closed-loop BS test), the R&S SMU200A high-end signal generator now supports realtime processing of hybrid automatic repeat request (HARQ) feedback information and uplink timing adjustment commands.

Using the HARQ function, a base station signals to a mobile phone whether it received a data packet correctly or incorrectly. If transmission was impaired, for example by fading, the base station requests retransmission of the packet with modified channel coding. The R&S SMU200A behaves in a way that is analogous to the HARQ processes of real user equipment. The signal generator can also be installed with options that introduce fading and additive white Gaussian noise (AWGN) to simulate transmission conditions as stipulated by the test specification. This makes it possible to verify the base station's response to the received data packets with respect to the standard, using a single instrument.

A base station uses uplink timing adjustment to adapt the timing of all transmitting mobile phones in order to prevent overlapping transmissions. Due to the R&S SMU200A's dual-path architecture, even the demanding uplink timing adjustment test can be performed with a single unit: The signal generator simulates a stationary UE on one path and a moving UE on the other. The moving UE can transmit with or without a time offset relative to the stationary UE.

The R&S SMU200A features RF performance that in many cases surpasses that of test UE. This provides base station developers with more accurate and reliable results. The signal generator can also be used for many other base station LTE receiver tests specified by the standard, and therefore minimizes test setup complexity.

The R&S SMU-K69 LTE closed-loop BS test option for the R&S SMU200A high-end vector signal generator is now available from Rohde & Schwarz. An LTE closed loop BS test option (R&S AMU-K69) is also available for the R&S AMU200A baseband signal generator and fading simulator.

"IPTV continues to be an attractive service for telcos to gain a competitive edge. Operators now have a broad choice in proven solutions that best match their future network goals," said Steve Oetegenn, chief sales and marketing officer. "We give full credit to the strength of our partnership ecosystem that enables us to deploy a cost-effective content security solution."

Huawei has announced that it has achieved the world's fastest LTE-advanced downlink speeds of up to 1.2 Gb/s at CTIA Wireless 2010 in Las Vegas, Nevada.

"Huawei's LTE-advanced technology enables future development of LTE for operators and provides unparalleled mobile broadband experiences for consumers. The record speeds, which are more than 40 times faster than existing commercial 3G networks, are expected to revolutionize user experience by meeting bandwidth requirements of data-heavy applications," said Karen Yu, President of Huawei USA. "Huawei will continue to invest heavily in LTE and is committed to promoting industry developments and maturity."

The demonstration utilized Huawei's SingleRAN prototype LTE-advanced solution with 80 MHz multi-carrier wideband radio and included following features: carrier aggregation (CA), 4x4 multi-input multi-output (MIMO), coordinated multipoint transmission (CoMP) and relay. Huawei's SingleRAN solution is said to support network multi-mode convergence and evolution while reducing total cost of ownership for operators.

Mobile data surpassed voice on a global basis during December of 2009, Ericsson has announced at the CTIA Wireless 2010 convention in Las Vegas. The finding is said to be based on Ericsson measurements from live networks covering all regions of the world.

Ericsson's findings show that data traffic globally grew 280% during each of the last two years, and is forecast to double annually over the next five years. The crossover occurred at approximately 140,000 Terabytes per month in both voice and data traffic. The data traffic increase is contributing to revenue growth for operators when more and more consumers use data traffic generating devices such as smartphones and PCs. During the same period, Ericsson measurements show that traffic in 3G networks surpassed that of 2G networks.

"This is a significant milestone with some 400 million mobile broadband subscriptions now generating more data traffic than the voice traffic from the total 4.6 billion mobile  subscriptions around the world," said Hans Vestberg, Ericsson President and CEO, speaking at a management briefing in Las Vegas. "Our view that the appeal of anywhere, anytime connectivity would drive mobile broadband growth is confirmed by the real world measurements under taken by Ericsson."

Social networking sites on mobile devices and mobile broadband-based PCs now account for a large percentage of mobile data traffic. For example, over 200 mobile operators in 60 countries are deploying and promoting Facebook mobile products, with over 100 million active users accessing Facebook through their mobile devices.

Supporting the view is a recent Ericsson consumer insights study showing that as much as 80% of mobile broadband users demand anytime, anywhere access. It has become part of daily life. The study was based on 4,580 consumers in six mature markets. It also finds that as mobile data traffic increases, the mobile broadband connection is becoming as personal as the mobile phone. 80% of respondents said they would not share their laptop with anyone and 65% would not share their mobile broadband connection.

With the new consumer behavior mobile networks will need to be dimensioned for data as well as voice. This is expected to require significant network modernization and transformation to all-IP technologies and new support systems, says Ericsson.

TM Forum and BT today unveiled the Cloud Service Broker (CSB) Catalyst, a new TM Forum rapid development and demonstration project that will define and create a trusted and governed cloud management platform, to simplify the delivery of complex cloud services to enterprise customers. 

The collaboration, which also involves Comptel Corporation, Infonova, OpenNMS Group and Square Hoop, will look at the role of the CSB in addressing enterprise cloud customer concerns in areas such as application performance, security and vendor lock-in. The platform will be demonstrated at Management World 2010, taking place May 18-20, 2010 in Nice.

In the TM Forum Catalyst project, developed by BT's Innovate & Design organisation, BT Global Services will serve as both an enterprise consumer and retailer of a number of complex cloud services.  The project, consisting of a definition and development phase and a final demonstration, will explore the aggregation, delivery and operation of cloud services while addressing a variety of trust and governance requirements.

The CSB Catalyst will address a number of the key concerns for Cloud adoption highlighted by TM Forum's Enterprise Cloud Buyers Council (ECBC).  The ECBC represents the interests of large Enterprise buyers and is the cornerstone of TM Forum's managing Cloud Services Initiative - an ecosystem of cloud buyers and sellers of which BT is a key member.  The goal of the ecosystem is to drive Tm Forum's Cloud Services Initiative in order to improve the understanding of the needs of enterprise cloud buyers and to remove any potential barriers to the uptake of cloud technology.

Comptel will provide an order portal and active service catalog, to manage the different components of a service, as well as a service designer to aid the rapid assembly of cloud services.  These concepts were initially demonstrated though previous catalyst collaborations with BT, namely the Product and Service Assembly (PSA) initiative and the Service Model catalyst.

Infonova will provide a billing catalog and billing engine, to manage the monetization of cloud services, and to enable the enterprise customer to be virtual operators of these services.

OpenNMS will provide monitoring services  as part of service assurance.

Square Hoop, through product catalogs, will orchestrate what is presented to the enterprise customer by aggregating product, service and billing information.

"As the cloud services market matures, there is the potential for these offerings to develop into complex combinations of services from a range of trusted and less trusted sources," said Gary Bruce, catalyst lead, BT Innovate & Design.  "The CSB Catalyst will explore resolutions to the issues that enterprises face when buying these types of combination cloud services and put in place the governance, security and transparency that will be imperative to their adoption."

John Gillam, BT Global Services said, "The Cloud Service Broker TM Forum Catalyst provides an excellent opportunity to address the barriers to cloud adoption for enterprise customers. Whilst enterprises wish to lever value from the cloud, they are apprehensive over losing control, citing areas of concern such as IT Governance, application performance, runaway costs, inadequate security and technology lock-in. The CSB addresses this by matching cloud services to each enterprise's needs, enforcing the right policies, and then showing how this can be backed up by an ongoing service level agreement. We believe developments of this nature will be of primary importance in future cloud services."

"The CSB explores some of the core issues that enterprises wishing to take advantage of future increasingly complex cloud services are likely to face," said Jim Warner, vice president, cloud programs, TM Forum.  "These issues are at the heart of the TM Forum's Managing Cloud Services initiative, of which the ECBC and the various cloud Catalysts are a critical part."

Interoute, owner operator of Europe's largest next-generation network, has completed two extensions to its Fast Trade service, connecting Lyon to Paris and Hamburg to Stockholm, reducing latency between key European trading platforms by 15 per cent.  The extensions will reduce round trip delay between London, Amsterdam and Paris and the rapidly growing financial markets in Scandinavia.

Financial institutions now have more choice than ever before when it comes to choosing which trading platform to list with, as more and more European markets are offering algorithmic trading. Interoute is said to be helping to accelerate this process by improving round trip delay between established and fast growing European trading platforms.  Interoute has direct connectivity agreements in place with a number of Europe's leading financial platforms, including NASDAQ OMX EUROPE (NEURO).

Lee Myall, UK Regional Director at Interoute, said: "Until recently high risk and poor latency restricted financial trading in the Scandinavian regions. The introduction of clearing houses in October 2009 addressed the issue of risk, and now Interoute Fast Trade is helping to reduce the latency between trading platforms. With the recent changes, the Scandinavian trading market is proving to be very attractive to European traders."

Since launching in August 2009, Interoute says it has received a surge in demand for its Fast Trade service, which offers ultra low latency connectivity between 28 countries in Europe.  A range of institutions, from large blue-chip banks to small, specialist electronic trading organisations and emerging specialists in high-frequency trading, have signed up for the service.

Fast Trade is a point to point service based on Interoute's SDH and wavelength platforms. When bandwidth is purchased, it is solely dedicated to the financial institution, ensuring that latency does not vary, even during the most volatile trading times.  Equally, the contractual round trip delay of Fast Trade circuits is based on the exact route that the circuit will take and is measured before handover to the nearest 10th of a millisecond. This forms the basis of its premium service level agreement, which allows organisations to cancel if the service level guarantee is breached during contract term.

According to the latest research from Informa Telecoms & Media, the IPTV market continues to expand with global IPTV subscriptions reaching 29.7 million at the end of 2009, up from 19.4 million a year earlier. In particular, IPTV has started to win significant share in several emerging markets and has made inroads into some developed mid-sized ones, albeit at a slow pace.

The number of quarterly net new subscriptions, or net additions, for broadband-based TV services from telecoms operators and ISPs reached a record high of 3.2 million in the last three months of last year. But just four countries accounted for nearly two-thirds of all IPTV subscriptions: France, the US, China and South Korea.

"IPTV still has a long way to go. The technology had only 5% of the multichannel-TV market and less than 2% penetration of the world's households, despite services being available in over 50 countries. In many markets, services have simply struggled to make progress against cable, satellite and terrestrial TV competition," comments Rob Gallagher, Principal Analyst at Informa Telecoms & Media.

"But the potential for delivering broadband-based services to the TV should not be underestimated. Despite the low number of success stories for conventional IPTV, the underlying technology is increasingly being embraced by cable, satellite and terrestrial TV providers as well as Internet firms, media groups and consumer electronics manufacturers."

IPTV has gained significant share in markets where one or more competing forms of multichannel TV are absent or weak, such as Iceland (81.0%), Qatar (80.0%), Cyprus (67.0%), Slovenia (35.0%), Croatia (25.0%), Estonia (25.0%), Montenegro (23.5%) and Greece (23.5%). Services also began to take the majority of net additions in some more competitive mid-sized markets in 2009, including Switzerland, Belgium, Singapore and Portugal.

F5 Networks, the global specialist in Application Delivery Networking, today announced that Swisscom, Switzerland's leading telecommunications provider, has implemented F5 solutions to support its nationwide ‘Internet for Schools' initiative.

The ‘Internet for Schools' program is aimed at getting every primary and secondary school in Switzerland connected to the internet. Swisscom leads the project, in conjunction with federal and local authorities. With over 5000 schools to support, and a potential user base of 900,000, key aspects of the project included stability, performance and reliability. Flexibility was also important given differing policies from canton (region) to canton on web content preferences.

The systems house eXecure recommended the F5 BIG-IP Local Traffic Manager, running on a mix of hardware platforms including F5's carrier-grade VIPRION chassis and blade system.

"This is something of a flagship project, given its extent," said Martin Theiler, Project Management and Engineering, Swisscom, "Since the implementation was concluded, the system has been running smoothly and is extremely stable. It's exactly right for our requirements, and we're particularly impressed with VIPRION's reliability and scalability, which enable us to increase processing power whenever we need to simply by adding an extra blade." 

"The system Swisscom, eXecure, and F5 developed is one of Switzerland's largest centralized web access and security initiatives," said Rolf Schauder, Regional Director for Central and Eastern Europe at F5. "The ability of F5 devices to interoperate with other security providers to allow for different levels of URL filtering per canton was a particularly noteworthy achievement. The solution we put in place, unique at the time in Switzerland, is applicable to service providers, governing bodies and the like on a global basis."
