Infonetics Forecasts Small Cell Market to Hit $2.7B in '17

The global small cell market to grow from a very small base now to $2.7 billion by 2017, according to a new forecast from Infonetics. Given the current pace of LTE rollouts worldwide, 4G small cell shipments are anticipated to overtake 3G shipments by the end of 2013.

“2013 is shaping up as a kick-off year for small cells, driven by 4G small cells deployed for capacity upgrades,” expects Stéphane Téral, principal analyst for mobile infrastructure and carrier economics at Infonetics Research. “AT&T, Sprint, and Verizon Wireless in the U.S., Vodafone in Europe, LG U+ in South Korea, and NTT DOCOMO in Japan have all announced major small cell plans, driven by the need to enhance the capacity of saturated macrocellular networks as they seek to deliver denser, higher-capacity coverage to tech-savvy populations in urban areas.”

Some highlights of the report:

  • South Korea’s SK Telecom has deployed close to 40,000 small cells and is the leading adopter of 4G public access femtocells to date.
  • Backhaul is no longer an inhibitor to small cell growth, but could remain an issue depending on factors such as location or mobile operator.
  • Geographically, Infonetics expects Asia Pacific to lead the small cell market in 2013 with 50% of all units shipped, followed by EMEA with 34%, and North America with 14%.

FCC Notifies on 1755-1780 MHz Band Auction Plans

The FCC officially notified the National Telecommunications and Information Administration (NTIA) at the U.S. Department of Commerce that it plans to commence the auction of licenses in the 1695–1710 MHz band and the 1755–1780 MHz band as early as September 2014.

The FCC is required to give notice at least 18 months prior to the commencement of any spectrum auction.

NTIA recently identified the 1695-1710 MHz band as the 15 megahertz of spectrum between 1675 MHz and 1710 MHz to be reallocated from federal use to non-federal use. The Spectrum Act now requires the Commission to allocate this identified spectrum for commercial use and to license the spectrum by February 2015.

The FCC also noted that Congress has also directed it to license the 2155-2 180 MHz band, and other bands, by February 2015.

  • Last year, the National Telecommunications and Information Administration (NTIA) proposed a spectrum sharing scheme between government and industry.  Specifically, the NTIA determined that 95 megahertz (MHz) of prime spectrum in the 1755 – 1850 MHz band could be repurposed for wireless broadband use. Over 20 federal agencies currently hold more than 3,100 individual frequency assignments in this band. Federal uses of this spectrum include law enforcement surveillance, military tactical communications, air combat training, precision-guided munitions, weather balloons, etc.

MSF: Interoperability Forum Folds, Leaves Impact on Industry

By Jim McEachern, Communications Consultant

The maturity of today’s multiservice network architecture owes a lot to initiatives like the MultiService Forum (MSF) Global MSF Interoperability (GMI) events over the past decade. These events, in partnership with GSMA, ETSI and ATIS, provided an effective vehicle for bringing together service providers and equipment suppliers to conduct proof of concept testing for emerging technologies. The MSF didn't initially conduct interoperability testing, but it quickly emerged as the unifying theme for everything the forum did. Here we review how the focus on interoperability emerged, the factors that contributed to the success of the interoperability program, and the reasons the MSF has deciding to close at this time.  

MSF’s Formative Years

The year was 1998, and the technology world was at war; Bellheads vs. Netheads. The Netheads believed the Internet had changed everything, and the old rules no longer applied. Bellheads believed IP could never deliver the quality and reliability that users demanded. It was before that great equalizer – reality - proved them both wrong. Before the Internet bubble burst. Before Broadband Internet was the norm. The MSF began in a world very different from the one we know today.

The inaugural meeting of the MSF in December 1998 brought together key service providers, system suppliers and test equipment vendors committed to developing and promoting open-architecture, multiservice Next Generation Networks. This commitment shaped the MSF:

  • Open-architecture encourages innovation, but complicates interoperability. Rigorous testing ensures the standards are accurate and complete.
  • Multiservice networks offer flexibility, but that very flexibility complicates testing unless a realistic network configuration is provided. 
  • Next Generation Networks introduce a new architecture that must be tested as an end-to-end network. 
Viewed through this lens, the MSF focus on interoperability testing isn’t surprising. 

Global MSF Interoperability (GMI)

In 2000, the market collapsed, and greed changed to fear. Next generation network architectures were complex and unproven. Interoperability testing was expensive, and repeating the tests in every carrier lab compounded the problem. This insight was the impetus for the first Global MSF Interoperability (GMI) event, with equipment in Europe, North America and Asia networked to form a single, global interoperability test bed. Three carriers - BT, NTT and Qwest – along with a dozen equipment vendors participated in the first event. GMI provided a valuable “proof of concept” test for critical interface standards and demonstrated the maturity of the next generation network architecture. GMI testing didn’t replace detailed “plugfest” testing focussed on a single interface. It didn’t replace vendor regression testing or carrier acceptance testing. Instead, GMI played a complementary role by validating the architecture and the standards.

The MSF held four GMI events from 2002 to 2008, introducing additional functionality with each event:
  • GMI 2002 validated the H.248 Media Gateway Controller protocol, decoupling service logic from the media gateway;
  • GMI 2004 added SIP trunking between H.248 based softswitches and saw KT join the list of participating carriers;
  • GMI 2006 introduced IMS, and included equipment in BT, KT, NTT, and Verizon labs; and
  • GMI 2008 added IMS services and saw participation by BT, China Mobile, National Communications System (NCS), the University of New Hampshire Interoperability Lab, Verizon and Vodafone, along with 22 network and test equipment vendors. For the first time ever, the MSF also partnered with another standards organization, validating key IPTV standards developed by ATIS. 

The Post-GMI Years

The original mission, validating open-architecture, multiservice, Next Generation Networks, had been achieved, but the MSF membership proposed smaller-scale interoperability testing in two additional areas; LTE and IP Interconnection. 

LTE: Standards for LTE include a new data architecture; the Enhanced Packet Core (EPC). The MSF conducted three LTE/EPC interoperability tests (IOT), with each event expanding the scope of testing.

  • LTE/EPC IOT (2010) focused on core components in the LTE/EPC network.
  • LTE VoLTE IOT (2011) introduced a key service, Voice over LTE (VoLTE), and validated key GSMA specifications for VoLTE in a joint MSF/GSMA event.
  • RCS/VoLTE IOT (2012), conducted jointly with GSMA and ETSI, introduced Rich Communication Services (RCS) to validate a complete LTE service scenario. 
Taken together, these three IOT events provided a complete proof of concept test for LTE/EPC, VoLTE and RCS services.

IP Interconnect: A significant portion of traffic between networks is still based on legacy TDM interfaces at the Network-Network Interface (NNI). IP interconnection exists, but is still complex. The MSF launched a series of test events to validate the enabling IP interconnect standards.

  • IP-IOT (2010) focussed on performance monitoring and reporting at the IP NNI.
  • ETS-NNI IOT (2013) validated standards for Emergency Telecommunications Service (ETS) across an IP-NNI. 

Success Factors

The success of the MSF interoperability program was driven by several factors.

Carrier driven: MSF interoperability events were built around major carrier procurement programs and held primarily in carrier labs. Vendors gained visibility with potential customers, and carriers assessed overall product maturity. It was a formula that drove both carrier and vendor interest in GMI.

Realistic Network Testing: The MSF was unique in assembling complete networks for interoperability events, enabling proof of concept testing for next generation network architectures.

Testing the Standards: GMI events tested the standards, as much as the products, sometimes uncovering errors or ambiguities in the underlying specifications. Improving the standards made a lasting contribution to the industry.

Cooperation: The MSF sought to cooperate with other forums rather than compete.


In February, the MSF membership voted to dissolve the forum.

Why make this decision immediately following another successful interoperability event? It had a lot to do with the MSF mission and mindset. The MSF focussed on gaps not addressed by other forums, for example, developing Implementation Agreements (IA) to improve interoperability by narrowing options and resolving ambiguities in existing standards. As interoperable standards matured, the need for IAs decreased and eventually disappeared. Similarly, the maturity of multiservice networks is removing the need for further large scale, global interoperability events. Interoperability testing will increasingly focus on specific markets or standards.


The MSF brought together key service providers, system suppliers and test equipment vendors committed to developing and promoting open-architecture, multiservice Next Generation Networks. The MSF’s work contributed to the maturity of multiservice network architectures, which changed the nature of interoperability testing. Recognizing this change, the MSF opted to close the forum.

The MSF leaves a legacy of interoperability scenarios, test configurations, test plans and event results that will be released for unrestricted use.   All MSF technical documents can be found at:

Mission Statement of the MSF

The MultiService Forum (MSF) is a global association of service providers, system suppliers and test equipment vendors committed to developing and promoting open-architecture, multiservice Next Generation Networks. The MSF, in partnership with GSMA, ETSI and ATIS, conducted a number of global interoperability events focussing on next generation technologies including SIP, IMS, IPTV, LTE, VoLTE and RCS. The events were hosted in leading service provider labs, and attracted wide participation from the telecommunications vendor community. 

IBM Discovers Atomic Technique to Charge Memory Chips

Researchers at IBM have discovered a new technique to charge memory chips by manipulating tiny ionic currents.

The discovery could pave the way for a new class of non-volatile memory and logic chips that would use less power than today's silicon based devices.

IBM has demonstrated that it is possible to reversibly transform metal oxides between insulating and conductive states by the insertion and removal of oxygen ions driven by electric fields at oxide-liquid interfaces. The company said its experiments show that the materials maintain a stable metallic state even when power to the device is removed.

"Our ability to understand and control matter at atomic scale dimensions allows us to engineer new materials and devices that operate on entirely different principles than the silicon based information technologies of today," said Dr. Stuart Parkin, an IBM Fellow at IBM Research. "Going beyond today's charge-based devices to those that use miniscule ionic currents to reversibly control the state of matter has the potential for new types of mobile devices. Using these devices and concepts in novel three-dimensional architectures could prevent the information technology industry from hitting a technology brick wall."

IBM's research is published in the peer-reviewed journal Science.

NTT DOCOMO Tests Solar Base Stations

NTT DOCOMO is launching field tests of three conventional mobile-network base stations that have been installed with solar panels, high capacity rechargeable batteries and green power controllers.

NTT DOCOMO will install 10 green base stations in the Kanto-Koshinetsu region of Japan by late summer, including the first three in Tokyo, Kanagawa and Yamanashi prefectures. The equipment was already by tested at its R&D Center from March 2012 to February 2013. 

The green base stations use solar panels to generate and store solar power during the daytime. If commercial power supply is cut off during a disaster, the station can rely solely on this power to run communication equipment during the day and use high-capacity, rechargeable batteries to store 14-16 hours’ worth of power when solar power is not available.

The solar panels to be used in the field test generate up to 4.19 kW, whereas the maximum power consumption of a base station is 2.0 kW. Remotely controlled green power controllers will manage power used by the base stations, including utility-provided electricity, solar panel-generated electricity, and high-capacity, rechargeable batteries that discharge their energy as required.

The company said its interest in disaster-proof, environmentally friendly base stations was spurred by the Great East Japan Earthquake.  NTT DOCOMO is also considering fuel cell technologies and wind-powered base stations.

NTT Comm Selects ALU's 7750 Edge Router

NTT Communications has selected Alcatel-Lucent's 7750 Service Router for its VPN enterprise services in Japan and worldwide.

Previously such services were supported by independent networks, but the move to a single, converged IP infrastructure provided by Alcatel-Lucent will simplify and streamline network management, cut the cost of network operations and help lower NTT Com's operational expenditure through a measurable decrease in energy consumption.

"In 2010 we deployed Alcatel-Lucent's service routers in the network that serves our international business customers, so the transformation of our network in Japan is a natural progression in this successful collaboration. Alcatel-Lucent's dedication to continuously enhancing their platforms with the very latest capabilities gives us the confidence that this new network will be able to address the fast-evolving expectations of our customers far into the future," Hiroshi Sono, Director of Technology, Network Services division of NTT Com.

The new devices, which are aimed at entry-level HD and HD-DVR platforms for cable MSOs, support Internet video streaming capabilities to multiple video devices simultaneously.  The SoCs integrate a high-performance CPU, 3D graphics and Full-Band Capture technologies.  In addition, the new STB SoCs also provide state-of-the-art Conditional Access (CA) and Digital Rights Management (DRM) security, enabling the conversion of content from CA to an IP-DRM streaming content.

Communications Workers of America Reject Contract with AT&T West

Wireline employees represented by the Communications Workers of America District 9 rejected a new labor contract that had been negotiated by the union and AT&T West.  The contract would have covered more than 17,000 AT&T employees in California and Nevada.

AT&T said it regretted this outcome as the new contract would have provided annual wage and pension increases.  Similar contracts had been accepted by CWA membership in other areas of the country.

AT&T said it will go back to the bargaining table.

Cisco's 100G CPAK CMOS-based Transceivers Deliver 70% Space and Power Savings

Cisco showcased its new 100 Gbps, CMOS-based transceiver technology at this week's OFC/NFOEC 2013 event in Anaheim, California. The new technology, which Cisco describes a breakthrough for the rollout of 100G services, is powered by Cisco’s nLight silicon.

By integrating advanced optics in complementary metal oxide semiconductor (CMOS) technology, Cisco is able to significantly increase face-plate density for 100G pluggable optics.

The Cisco "CPAK" transceiver, which will initially be available on the Cisco ONS 15454 MSTP 100 G coherent transponder, reduces space and power requirements by over 70 percent compared with alternative transceiver form factors, such as CFP. Future routing and switching line cards will also incorporate CPAK technology.

"Cisco’s CMOS design allows us to utilize the immense and highly evolved CMOS IC fabrication industry, which delivers low-cost, highly integrated and reliable components,” said Bill Gartner, vice president and general manager of Cisco’s High End Routing and Optical business unit. “We see this as a critical differentiator to reduce the power, cost and size of components, and it will help make 100 gigabit as widely deployed as 10 gigabit is today. No other industry solution offers as much opportunity to reduce 100 gigabit deployment costs as the Cisco CPAK.”

Cisco’s first line card to incorporate CPAK technology is the 100Gbps CPAK Coherent DWDM line card, compatible with the ONS 15454 MSTP platform.  The card uses Cisco’s 100GE IEEE standards-based LR4, SR10 and ER4 CPAK pluggables on the client interface and Cisco’ ultra long-haul coherent technology on the network facing (trunk) interface.

In addition, Cisco announced that its 100G DWDM powered by nLight technology can cover distances of up to 4,800 km without the need for signal regeneration.  The density of the technology enables 6 x 100G Transponders in a 6 RU chassis, or the equivalent of 8.4 Terabits of I/O in a single rack.

Cisco also noted that its nLight silicon photonics could be further developed in state-of-the-art 28nm CMOS silicon to enable 400Gbps and 1 Tbps rates.

China Mobile and Ericsson Test Uplink Coordinated Multipoint in the TD-LTE

China Mobile and Ericsson have verified the performance of Uplink Coordinated Multipoint (UL CoMP) in a TD-LTE trial network. The companies confirmed that in cell edge areas, UL CoMP can achieve 50-100 percent uplink throughput gain.

Ericsson said UL CoMP is one of the key technologies of LTE Advanced that can greatly improve network capacity and coverage.  The technology enhances uplink signal strength and effectively suppresses interference from neighboring cells. It is implemented at the network side with no requirement on terminals or protocols.

Currently, China Mobile is evaluating the network performance improvement brought by the introduction of UL CoMP to determine the priority of this technology in their future standard.

Huawei Shows WDM Prototype Carrying 20x 2 Tbps Channels

Huawei is showcasing a 40T Wavelength Division Multiplexing (WDM) prototype at this week's OFC/NFOEC 2013 event in Anaheim, California.

The prototype supports simultaneous transmission of 20 C-band optical channels running at 2 Tbps, providing an industry-leading capacity of up to 40 Tbps per fiber.

Huawei cited three innovations in its platform:

The combined use of Electrical Orthogonal Frequency Division Multiplexing (eOFDM) and frequency-domain Hybrid Quadrature Amplitude Modulation (QAM) technologies substantially improve spectrum efficiency to 10 bit/s/Hz.

The combined use of Flex-Optical Digital Signal Processing (Flex ODSP) and Hybrid Soft-/Hard-Decision Multi-level Coding (HMLC) technologies extend the transmission distance to beyond 1,000 km over common single-mode fiber and Erbium-Doped Fiber Amplifiers (EDFAs).

Software-implemented transceiver technology allows optical modulation formats such as Quadrature Phase-Shift Keying (QPSK), 16QAM, 32QAM, and 64QAM to be adjusted or combined, achieving a configurable transmission rate and distance for each service. As a result, dynamic service needs in varied scenarios can be easily met.

In 2012, Huawei completed a 2 Tbps WDM field trial with Vodafone, achieving up to 3,325 km transmission for 2 Tbps signals. The 40T WDM prototype is another major breakthrough in high-speed transmission proving current commercial optical networks will be ready for the upcoming flood of digital traffic.

Huawei Develops All Optical Switching

Huawei showcased prototypes of an All-Optical Switching platform at this week's OFC/NFOEC 2013 event in Anaheim, California. The Optical Burst Transport Network (OBTN) prototype joins a Petabit Photonic Cross-Connect (PPXC) prototype showcased at earlier OFC/NFOEC events. This new All-Optical Switching Network architecture makes further advances in any-topology networking and coherent transmission for optical bursts.

Huawei said All-Optical Switching Network technology could eliminate the need for Optical-Electrical-Optical (OEO) conversion or electrical switching. Huawei solves the challenge of switching multi-dimensional and multi-wavelength optical bursts through the use of Optical Time Slot Interchange (OTSI) technology. This enables any-topology, all-optical contention-less networking. 

Huawei is also demonstrating 100 Gbps optical burst transceiving, an industry first.  

Huawei noted that its All-Optical Switching Network architecture is compatible with traditional WDM and Reconfigurable Optical Add/Drop Multiplexer (ROADM) networks.

Proximion Launches 16-port Flexible-Grid Optical Layer Monitor

Proximion AB, which develops optical modules and sub-systems based on Fiber Bragg Grating (FBG) technology, introduced a 16-port, flexible-grid Optical Layer Monitoring product as part of its "WISTOM" line.  An 8-port version was already available.

The 16-port WISTOM measures channel power, frequency, OSNR, wavelength drift, line-width & capacity utilization of 16 DWDM ports independently of channel plan, channel grid, modulation format or data rate.

"We are proud to introduce the 16-port WISTOM that not only has twice the number of ports to competing subsystems, it is also the only subsystem that scans the complete C-band in less than 0.1 milliseconds and reports channel specific problems with a response time of less than 10 milliseconds, while simultaneously measuring all key optical parameters”, says Adel Asseh, VP Product Management at Proximion.
