Ericsson brings carrier-grade Wi-Fi to mobile broadband

May 21, 2013, 09:30 (CEST)

  • User experience of Wi-Fi moves beyond "best effort" through seamless integration with mobile networks
  • Ericsson's industry-first, real-time traffic steering dynamically optimizes operator network resources
  • New, high-performance indoor Wi-Fi, cloud controller options and integrated mobile broadband management strengthen Ericsson's heterogeneous networks differentiation

A smooth and seamless integration of Wi-Fi access is an increasingly important part of any mobile broadband service. Most smartphone users have experienced the frustration of being automatically connected to a Wi-Fi network only to face a noticeably slower connection speed.

To ensure users always get the best connection, Ericsson (NASDAQ: ERIC) today announces its 3GPP compliant Wi-Fi network access, control and management solutions. These enable mobile operators to easily incorporate Wi-Fi in their heterogeneous network strategy, while delivering a consistently high-performance user experience, even in high traffic areas. Incorporating Wi-Fi is a key focus of tier-one mobile operators.

Daryl Schoolar, Principal Analyst, Network Infrastructure at Ovum, said: "Ericsson has clearly differentiated its carrier Wi-Fi solution through tighter integration with mobile operator's 3GPP access, control and network management. This approach should yield a better end-user experience by preventing some of Wi-Fi's well-known bad habits from being imposed upon users. At the same time, operators should welcome the tight integration of Wi-Fi and mobile, as exemplified by Ericsson's solution, thanks to the benefits derived from improving network resource optimization and ease in implementing and delivering Wi-Fi service offerings."

Key to the user experience is an Ericsson industry-first feature that automatically selects the best connection: real-time traffic steering. Ericsson's real-time traffic steering is a software upgrade that constantly assesses key performance indicators in both the mobile 3GPP network and the Wi-Fi network before dynamically and seamlessly shifting the consumer's smartphone connection between networks. This ensures the best user experience and optimizes network resources. Real-time traffic steering is a network-driven feature requiring no user intervention or additional device software.  Ericsson also now supports access selection, a self-optimizing network (SON) feature enabling load-balancing between Wi-Fi and 3GPP networks to optimize the average user experience.

Thomas Noren, Vice President and Head of Product Area Radio, Ericsson, says: "Heterogeneous network strategies among leading mobile operators are focused on delivering a great mobile broadband experience to their customers, wherever they are. By coordinating licensed small cells with the macro cell, as we announced earlier this year, and intelligently integrating Wi-Fi and 3GPP throughout the network, we're providing operators with the most effective way to deliver consistently high performance consumer connections."

With indoor areas increasingly prone to mobile network congestion, Ericsson has also developed the first 802.11ac access point designed to enable mobile operators to deliver supplemental small cell or standalone Wi-Fi coverage indoors. The 802.11ac standard is common on tablets and increasingly prevalent on smartphones.

Two new cloud-controller options, both featuring 3GPP-standard interfaces to the mobile core, make it easier and more cost-efficient for operators to add Wi-Fi to their existing mobile services. The Ericsson Evo Controller now features a Wi-Fi controller blade, the WIC 8030. A new standalone controller, the WIC 8100, supports up to 10,000 access points and 500,000 concurrent subscribers, allowing operators to consolidate multiple Wi-Fi networks from a centralized location in a cost-efficient way.

Ericsson is also introducing integrated management of Wi-Fi and 3GPP networks on a common platform, simplifying operations and reducing network costs.

These new Wi-Fi 3GPP integration products and features provide complementary and incremental benefits to emerging industry standard features that Ericsson supports, including:  Access Network Discovery and Selection Function (ANDSF), IP session mobility (also referred to as IP address preservation) and Wi-Fi CERTIFIED Passpoint(TM) (based on the Wi-Fi Alliance Hotspot 2.0 Specification).  Ericsson also offers Wi-Fi 3GPP integration solutions to optimize the user experience for operators targeting residential Wi-Fi coverage.  At MWC 2013, Ericsson announced a new Wi-Fi Gateway application on the Smart Services Router (SSR) which also supports integration of Wi-Fi networks with mobile broadband infrastructure.

New MINI-LINK products launched for small cells

Feb 18, 2013 Categories: Portfolio
  • Expanded capability gives operators greater flexibility to deploy MINI-LINK products as backhaul solutions for small cells, thereby enabling high network performance
  • MINI-LINK performance proven for non-line-of-sight usage
  • New additions to MINI-LINK portfolio include several IP-based backhaul products catering for mobile-broadband growth

Providing seamless network performance in dense city environments is a challenge. The large number of buildings and other obstacles makes it difficult to lay cables and complicates wireless connections that typically rely on microwave transmission using line-of-sight (LOS) propagation. This means there can be no buildings, trees or hills between antennas.

To overcome this problem, Ericsson (NASDAQ:ERIC) has now validated that MINI-LINK products in traditional frequency bands can operate in non-line-of-sight (NLOS) conditions with high performance, in trials with MetroPCS in Los Angeles, USA. In addition, Ericsson is launching MINI-LINK products for small cells, including the MINI-LINK 3060 that was shown as a concept at the 2012 Mobile World Congress.

"NLOS microwave is a critical component of building backhaul networks where clutter is an issue and especially for heterogeneous networks," said Malcolm Lorang, co-founder, Senior Vice President and Chief Technology Officer of MetroPCS. "We are pleased with the results of the MINI-LINK trial in the challenging Los Angeles environment and look forward to further testing.

Ericsson MINI-LINK - Solving Small Cells Backhaul Challenge


Ola Gustafsson, Head of Product Line Microwave and Mobile Backhaul, Ericsson says: "Conventional NLOS products work in the sub-6GHz band using OFDM (orthogonal frequency division multiplexing) technology, for multipath handling. The problem is that the available spectrum below 6GHz is very limited and would be insufficient for small-cell backhaul. Ericsson has now proved, with extensive research, that MINI-LINK products operating in the 23-60GHz bands offer higher throughput and increased stability compared with sub-6 systems also under NLOS conditions. This expands the possibilities to deploy MINI-LINK as the backhaul solution for small cells, thereby enabling increased network performance."

MINI-LINK is designed for hops over several kilometers, with a market-leading system gain and very robust equalizers. Over short hops, diffraction and reflections caused by the environment can actually be used to overcome obstructions between the macro layer nodes that are often positioned on top of high buildings, and the small cells positioned at street level. With this approach, throughput will be very high and stable, which is important for mobile backhaul.

Ericsson is also launching several IP-based backhaul products to cater for mobile broadband growth and to execute on its 4G IP network vision. These products will extend its leading MINI-LINK portfolio with IP/MPLS (multiprotocol label switching) support for fiber- and/or microwave-based backhaul, innovative design in the 60GHz band for small-cell deployments and an enhanced Gbps solution in the E-band. The MINI-LINK LH has also been expanded by the addition of a compact solution for cost-efficient migration to packet and modular site solutions.

In addition to helping operators prepare all-IP networks, these new products offer benefits such as high system gain for improved performance, spectrum efficiency,  synchronization solutions, end-to-end QoS support, as well as integrated aggregation for both TDM (time division multiplex) and packet traffic.

The products being launched are:

  • MINI-LINK SP 415 and 420 - packet aggregation nodes for L3 VPN based on IP/MPLS
  • MINI-LINK PT 3060 - microwave node optimized for small-cell deployments (60GHz)
  • MINI-LINK PT 6020 - 1Gbps (in one 250MHz carrier) microwave node in the E- band (70-80GHz)
  • MINI-LINK LH Compact - long-haul microwave solution for reuse of existing cabinets.

Ausgrid, Australia: Smart grid network to use LTE

25 Aug, 2011 - Categories: Industry

Australia’s largest electricity distributor builds wireless smart grid network. 4G wireless is set to be an integral part of Australia’s leading "smart grid" rollout after an agreement between Ericsson and Ausgrid, Australia’s largest energy distributor (formerly EnergyAustralia).

Ericsson has designed and integrated a multivendor wireless access network that enables two-way communications between electrical control devices, back-end systems and households. The network is being rolled out in 2011 across 150 sites covering the metropolitan area of Sydney, Australia, and regional areas north of Sydney.

The telecommunications network will collect data from 12,000 smart monitoring devices being installed on the electricity distribution network, up to 3,000 mobile field computers, and 200 zone substations. Ausgrid is a leader in introducing sophisticated and efficient energy distribution to Australians. The company’s "Smart Home" demonstration home showcases the benefits of the latest technologies for consumers, including smart metering and intelligent infrastructure. (http://www. ausgrid.com.au/smarthome)

Smart grid

A smart grid gives households greater control over their bills and environmental impact, and allows renewable energy sources to be better integrated. A smart grid also improves the reliability of the electricity network by allowing it to self-heal when faults occur, and allows effective conditionbased maintenance to reduce the likelihood of faults. The operations teams can be provided with real-time awareness of the electricity network status, improving both operations and planning.

Ausgrid Managing Director George Maltabarow explained: "A smart grid needs a communications platform to bring real-time data back from our substations, field devices and smart meters so we can turn it into useful information for field staff, engineers and households. The communications network is essential to transforming the electricity network into a two-way grid that is smarter, greener, more reliable and more interactive for households." Ausgrid began trials of a communications network in 2009 with an initial deployment of WiMAX radio equipment. Under the Ericsson agreement the existing network has been greatly extended, and trials of an LTE platform will commence in 2011, with the aim to migrate to a full LTE network based on the success of those trials.

Maltabarow continued: "We are now rolling out a WiMAX communications network and will begin trials of an LTE platform at 15 sites. By using the same 4G technology as mobile carriers, we will benefit from economies of scale for chip, device and equipment pricing as 3G networks around the world migrate to LTE."

LTE – the next generation

LTE, the next generation of mobile communication technology, enables the fast transfer of huge amounts of data in an efficient and cost-effective way, optimizing the use of the frequency spectrum. With increased speed and decreased latency, LTE is specifically well suited to machine-to-machine (M2M) applications such as smart grid.

Under the agreement between Ausgrid and Ericsson, Ericsson will provide equipment, software and services, and will leverage the Australian-based Ericsson Global LTE Competence Centre, and Ericsson’s strong local expertise in network design, planning and integration.

"The utility sector is being transformed, as it simultaneously changes to meet new environmental and service challenges, and introduces new and powerful technologies," said Sam Saba, CEO, Ericsson Australia/NZ. "In particular, modern wireless communications based on carrier grade open standards is a fundamental requirement. Communications is the enabling technology for smart grids."

"As a global communications leader with extensive multivendor systems integration experience, Ericsson is well placed to partner with utilities as they transform their electricity distribution networks into smart grids," said Saba.

Ericsson is the world’s leader in telecommunications technology and services and is leading the way in the rollout of LTE with services now operating in Europe, the US and Asia, as well as Australia.

Ericsson has been driving open standards and has had the highest impact on the released LTE specifications. Ericsson expects to hold 25 percent of all essential patents for LTE, making it the largest patent holder in the industry.

Customer profile

The Ausgrid electricity network provides power to 1.6 million homes and businesses throughout Sydney, the Hunter Valley region, Newcastle and the Central Coast areas of New South Wales. That network is made up of more than 200 large electricity substations, 500,000 power poles, 30,000 small distribution substations and almost 50,000km of aerial and underground electricity cables. The state-government owned corporation has been operating for more than 100 years, and today delivers energy to more users than any other distributor in Australia. It is also delivering one of Australia’s largest infrastructure programs – an AUD 8 billion upgrade of the electricity network.

Ericsson 3E digital voltage-regulators now support 93 PMBus commands to reduce energy consumption

16 June, 2011 - Categories: Ericsson Power Modules


  • More freedom for designers to dynamically optimize energy management
  • Increased efficiency with fewer components
  • Fully compliant with PMBus commands
  • Design simplified; time-to-market reduced

Based on digital-core controllers, the Ericsson 3E second generation of voltage regulators, the 12A BMR462, the 20A BMR463 and the 40A BMR464, now support 93 PMBus commands, allowing designers to monitor and control energy distribution from system level to board level.

The number of commands supported by the BMR462, BMR463 and BMR464, facilitate optimization of power-module configurations to varying load conditions.

This minimizes power losses and reduces energy consumption by sending a command to automatically adjust the output voltage as the load changes; a lower voltage is optimal for low-load demand and a higher voltage as the load increases. It is also possible to shut down selected modules and reactivate them on-demand.

"Since Ericsson introduced its first digitally controlled voltage regulator November 2008, we have seen considerable increase of demand from system architects to optimize energy management to a very high degree.

They are also motivated by the possibilities offered by PMBus and demand additional features that make it possible to fully integrate voltage regulators into their digital power management architecture," said Patrick Le Fèvre, marketing and communication director of Ericsson Power Modules.

“With more than a million mobile and wireless broadband customers joining Telstra in the past 12 months, and data usage on the Next G network doubling every year, the increased network capacity LTE will provide is vital,” Mr Wright said.

By the end of 2011 when the initial 4G LTE network has been deployed, Telstra will sell dual mode LTE/HSPA+ mobile broadband devices that will operate seamlessly across the 1800MHz and 850MHz spectrum bands, giving Telstra customers the benefits of 4G where it is available and a seamless switchover to 3G HSPA technology across the expansive Next G footprint.

Ericsson chief executive officer Australia and New Zealand, Mr Sam Saba, said; “Some of the world’s leading operators are seriously considering LTE in the 1800MHz band and the growing momentum will accelerate the development of LTE devices.

"LTE represents the future of mobile broadband. Its ability to deliver improvements in network capacity will allow operators to meet the growing demand for data traffic over the coming years.”

Ericsson has been driving open standards and has had the highest impact on the released LTE specifications. Ericsson expects to hold 25 percent of all essential patents for LTE, making it the largest patent holder in the industry.

Ericsson energy-optimized intermediate bus DC/DC converters offer unprecedented efficiency across a wide load range

11 February 2011 - Categories: Ericsson Power Modules


  • Integral energy optimization algorithm for 96% peak efficiency and substantially flat curve from 15% to 100% load
  • Footprint 100% compatible with “Five-pin” intermediate bus converters in existing designs
  • Tightly regulated output voltage
  • Based on a proven family of digitally-controlled DC/DC converters launched in 2008

Based on a digital core controller embedding an Ericsson efficiency optimizer algorithm, and fully compliant with the “Five-pin” de-facto industry standard for intermediate bus converters (IBC), Ericsson Power Modules introduces a series of variants to its BMR453 and BMR454 DC/DC converters.

The latest versions omit the digital interfaces found in early models, simplifying system design. Ericsson programs the modules in its factory for any output voltage from 5V to 13V. This, together with the energy optimization algorithm, ensures that the modules operate with the highest possible efficiency over wide-ranging load conditions.

The result is lowest power dissipation, lowest temperature operation, highest reliability and maximum energy saving.

With 96.5% peak efficiency and a substantially flat efficiency curve from 15% to 100% load, the quarter-brick BMR453 offers up to 396W output power (or up to 33A) and the eighth-brick BMR454 offers up to 240W (or up to 20A).

Industry-standard “Five-pin” compatibility simplifies migration from static intermediate bus architectures to more advanced topologies such as Dynamic Bus Voltage, which the latest versions of BMR453 and BM454 accommodate through their digital interface.

Ericsson’s digital voltage regulator offers unprecedented levels of control and energy saving

4 February 2011 - Categories: Ericsson Power Modules


  • Highly flexible monitoring and control PMBus compliant
  • Optimized power consumption
  • Parallelable for end user versatility

Ericsson Power Modules’ 3E series BMR463 is a second-generation, digital point-of-load regulator with unprecedented functionality. It enables systems architects to fully monitor and dynamically control the energy that is delivered to strategic components such as processors, FPGAs, ASICs and others, down to a very low, highly economical level.

Following on from the BMR450 and BMR451 regulators, the 20A rated BMR463 is optimized for paralleling up to eight modules. This configuration of eight BMR463s can deliver 160A with each module able to be paralleled and un-paralleled on demand, dynamically tracking and reducing the power consumption as required and optimizing the configuration for a very wide range of load conditions.

Additionally, when parallel mode is activated, an interleaving-operation reduces electromagnetic interference and current-peak levels. A built-in module-to-module Group Communication Bus (GCB) ensures that current sharing is precisely controlled, guaranteeing that at any point of operation each BMR463 delivers the exact current required by the payload while keeping efficiency high.

By embedding a digital core in conjunction with a highly efficient power-train and a so-called ‘U-shape’ output stage, the BMR463’s construction is highly optimized to minimize power losses. Power dissipation is thereby reduced, resulting in enhanced lifetime and reliability.

As a second generation digitally controlled regulator, the BMR463 is advanced in terms of the number of features offered in such a small footprint. It is the result of an active cooperation program between Ericsson’s customers and power modules designers to develop a new series of point-of-load modules that will greatly contribute to reducing energy consumption.

Ericsson power module's 100W 1/4 brick shortens time to market for power radio applications

1 December 2010 - Categories: Ericsson Power Modules


  • Wide output voltage range accommodates multiple power-amplifiers
  • Optimized design reduces component count and increases reliability
  • High efficiency reduces power dissipation and saves energy

Reducing cost and improving efficiency, the topology used in Ericsson Power Modules’ PKM4116ND quarter brick DC/DC converter has been highly optimized to lower the number of components while simultaneously reducing power losses. Enabling systems designers to shorten time-to-market, the PKM4116ND is an industry standard quarter-brick product and is 100% pin-to-pin compatible with similar products available to the market.

The PKM4116ND is primarily designed to power radio-applications and is optimized for the new generation of micro cell transmitters requiring a 100W power module with the flexibility to adjust its output voltage within the range 23.8V to 32.8V.

The main application area addressed by the PKM416ND is in RFPA (radio frequency power amplifier) and other applications requiring isolation from the 48V system bus voltage, and offering a stable output voltage in a range of 24 to 30V. This product is also suitable for small systems remote feeding power architectures such as in-door Wi-Fi transmitters.

Further optimised for RFPA, the PKM4116ND can be deployed in sealed box applications with its heatsink fixed directly to the host equipment chassis. Using Ericsson’s thermal optimization technology, the PKM4116ND’s layout has been optimized to distribute the major heat dissipating components, eliminating hot spots and improving cooling through natural thermal conduction from board to cold plate.

Thus, cooling through its optional baseplate or through a thermal-pad applied between the PKM4116ND board and the equipment chassis is easily facilitated. This feature, combined with low power losses resulting from a high efficiency topology give the PKM4116ND an unprecedented quality and reliability level when used in sealed-box or in other applications or conditions where natural convection cooling is the only way to dissipate power.

Power supplies go digital

16 September 2010 - Categories: Ericsson Power Modules



Digital power techniques have been proposed for some time, but have not been able to compete successfully with analog solutions. Thanks to increasing integrated-circuit density, hard work on the part of semiconductor suppliers, and a mature and reliable, complementary, metal-oxide semiconductor technology, digital processing for power-conversion applications now is very attractive.

More importantly, the use of digital techniques results in capabilities and performance at both the power-supply and system levels that are not possible with analog techniques.

While much of the publicity and controversy about digital power techniques is focused on power-system management issues, the most important issue – and the ultimate driver for its acceptance – will be the benefits that they bring to power supply itself. These benefits are real, measurable and available with today's technology.

Benefits include: improved efficiency; improved reliability due to higher integration of digital control circuitry; reduced system cost because of fewer decoupling capacitors due to enhanced load transient response of adaptive digital control; increased power-supply density due to smaller digital control circuitry; tighter output-voltage tolerances due to enhanced initial set-point trimming; and lower overall cost of ownership.
