NEC Develops Self Organizing Network Technologies for Heterogeneous LTE Networks

NEC Corporation announced today the development of Self Organizing Network (SON) technologies for its heterogeneous LTE solution. NEC’s latest SON technologies successfully tackle two of the most challenging scenarios in LTE deployment: highly dynamic traffic hotspot and multiple user mobility this maintains a high quality user experience in various challenging environments while significantly reducing operators’ CAPEX and OPEX.

SON solutions reduce the Operation and Maintain (O&M) cost of mobile networks by using automated and intelligent procedures to replace human intervention without compromising network performance. However, a major challenge to the design and development of SON technologies is how to achieve high quality user experience and optimize the network in a heterogeneous network while taking into account varying regional traffic characteristics and user mobility.

NEC’s small cell LTE solution enables mobile operators to install new base stations in any traffic hotspot area without the need to modify their existing networks. By applying NEC’s SON technologies, NEC’s small cell eNBs can independently recognize the distribution and movement of users automatically and tune dynamically various parameters to optimize its coverage and improve the cell-edge performance. This could help achieve more uniform and stable high quality user experience at densely populated traffic hotspot areas.

NEC has developed handover optimization in its SON technologies to provide high quality transmission for users with various mobility characteristics. In its design, handover settings from macro to small cell coverage are automatically adjusted in response to varying propagation conditions. For example, macro base stations can dynamically restrain handover to small cell base stations for the fast-moving user. On the other hand, macro base stations favour the handover to small cell base stations for slow moving or static terminals.

The performance of these developed SON technologies are thoroughly evaluated and tested by using NEC’s unique 3-dimensional simulator, which is more close to the real world compared its 2-D counterparts. The performance results demonstrate that, by using NEC’s SON technologies, the cell edge users’ user data rate was increased up to 2 times. In addition, the radio link failure rate was significantly reduced.

NEC will exhibit these technologies at Stand 8A125 at Mobile World Congress 2011” in Barcelona, Spain from February 14 17, 2011.

Pannon selects Alac-Lu for IP upgrade (Hungary)

www.WirelessFederation.com/news: Alcatel-Lucent’s all-IP solution has been selected by Hungarian mobile operator Pannon, part of the Telenor Group, to unify its mobile core network and its existing IP/MPLS-based mobile backhaul infrastructure.

Pannon will lay the foundation for the future introduction of Long Term Evolution (LTE) technology, besides catering to the anticipated surge in demand in mobile traffic after this IP upgrade. Currently, 3.6 million customers are served and 33% of the domestic mobile market is controlled by Pannon.

According to Kenneth Fredriksen, general manager for ZTE’s Telenor Global Business Unit, LTE will enable mobile users to experience high speed mobile broadband and exciting new services and with this commercial trial, ZTE aims to demonstrate the superior performance of the LTE solutions to Pannon and the Telenor group.

SFR & Alca-Lu sign 2G/3G expansion deal

www.WirelessFederation.com/news: Alcatel-Lucent has been selected by French mobile operator SFR to carry out a major expansion and upgrade of its 2G/3G networks besides working together for the trial of Long Term Evolution (LTE) mobile broadband technology.

Smooth upgrade path to HSPA+ will be possible for SFR because of the deal to meet growing demand for mobile broadband services. Converged RAN (radio access network) solution will be provided by Alca- Lu enabling the cellco to reach a greater number of subscribers and further improve its services.

Meanwhile, the trial of 4G technology under the deal will include the delivery of an end-to-end LTE solution including base stations (eNodeBs), Evolved Packet Core (EPC) and associated management systems.

Motorola launches Long Term Evolution (LTE) trial network in the UK

Motorola launched its LTE trial network and testing lab in Swindon, UK. The occasion was marked with a live, over the air, standards compliant LTE call during which high-speed data services were streamed using Motorola’s LTE infrastructure operating in the 2.6GHz spectrum and a prototype LTE device.
This latest expansion of Motorola’s LTE trial facilities offers operators the ability to engage in LTE technology field trials and detailed real-world equipment testing at the UK site. Additionally, Motorola can host the core elements of the LTE network for operators that require a hosted LTE trial in EMEA. The network and trial activity is fully supported by Motorola services, giving operators access to Motorola’s expertise in deploying and optimizing OFDM-based mobile broadband networks as well as developing 4G migration strategies.

“Motorola is at the forefront of 4G development which will address the mobility demands of today’s consumers who are looking for personalized media experiences and operators looking to lower their cost per bit and gain a competitive advantage,” said Joe Cozzolino, Senior Vice President and General Manager, Motorola Home & Networks Mobility, EMEA & Asia Pacific. “With our latest trial network we look forward to working closely with our customers in EMEA as they transition to LTE during 2009 and beyond.”

Within its LTE lab in Swindon, UK, Motorola engineers work on LTE radio frequency and self organising network (SON) development. In addition, the site in Swindon remains a center of excellence for Motorola base station transceiver (BTS) development for GSM and now LTE. Development of Motorola’s LTE solutions is also conducted in Arlington Heights, Illinois; Fort Worth, Texas; Beijing, China and Bangalore, India.

Motorola’s first commercial release of LTE solutions later this year will include products for the 700MHz and 2.6GHz spectrum bands to help operators increase coverage and capacity of their networks as they strive to meet the growing demand for mobile broadband services. Motorola is engaged with operators in North America, Europe and the Asia Pacific region for LTE field trial activity.
LTE brings true mobile broadband, giving users a personalized, affordable media experience at home and while on the go. LTE is based on orthogonal frequency division multiplexing (OFDM), a next-generation radio frequency technology that has high spectral efficiency, and utilizes an all-IP flat architecture, resulting in a much increased capacity and a lower cost per bit that enables the delivery of mobile broadband services to the mass market.
