Huawei launched two new LTE related products at Mobile World Congress (MWC) 2012 this week, in addition to the adaptive radio unit and AtomCell GigaSite products unveiled last week (24 February 2012). These included the world’s first 10GE CSR (Cell Site Router) ATN 950B for LTE backhaul and an LTE-A inter-band carrier aggregation solution.
ATN 950B cell site router
The ATN 950B strengthens the capabilities of Huawei’s mobile broadband solutions, enabling carriers to deploy extra-large LTE networks and provide enhanced mobile data services for its users. With its small-size and large capacity, the ATN 950B is designed to meet the demand of rapid bandwidth growth for LTE, by providing larger network bandwidth, multi-services, higher deployment efficiency, and lower maintenance.
As the world’s first 10GE CSR, ATN 950B covers bandwidth increases from 1GE to 10GE during LTE phases, even beyond LTE. ATN 950B is 300mm deep and can share the same rack with eNodeB. ATN 950B also supports 10GE ring, L2VPN, L3VPN, and H-QoS and can flexibly schedule various services on complex networks. At the same time, it supports synchronization with multiple precise clocks, such as ACR, synchronous Ethernet, and IEEE1588v2.
LTE-A inter-band carrier aggregation solution
The LTE-A (LTE-Advanced) inter-band carrier aggregation (CA) solution is designed to improve the utilization of discontinued spectrum resources and increase user peak rate and network throughput.
The company said that in an era of mobile broadband (MBB), diversified MBB services and increasing data traffic used by individual subscribers have a huge impact on mobile networks. Scarcity of spectrum resources, however, prevents proportional increases in network capacity. In recent years there has been considerable discussion about how operators can effectively utilize spectrum assets for greater capacity.
At the MWC 2012, Huawei demonstrations of the LTE-A inter-band CA solution showed inter-band carrier aggregation at 800MHz and 2.6GHz with peak throughput of over 225Mb/s. The solution is expected to revolutionize user experience by allowing networks to meet bandwidth requirements of data-heavy applications, marking an industry milestone.
Inter-band CA is the most difficult to realize of the three forms of LTE-A CA (continuous CA within the band, non-continuous CA within the band, and non-continuous CA outside of the band). Given existing spectrum allocation policies, inter-band CA not only dramatically increases spectrum resource utilization, but also helps operators flexibly combine bandwidth and solve spectrum discontinuity to increase user peak rates and experience. With this solution, operators enjoy greater returns and spectrum assets will appreciate in value.
Energy-saving site display cabinet
Huawie also released a new energy-efficient and compact equipment site solution at MWC, which will help address the challenges and intense competition operators face, particularly in urban areas where there is high energy consumption and little space for new equipment sites.
Huawei’s solution is a standard all-in-one cabinet that integrates four power supply units, a battery backup unit, a transmitter, a precision cooling storage system, intelligent cooling technology and a single controller. This solution can provide energy savings of more than 30% and allows for smooth evolution.
Huawei has also developed Mini-shelter, a range of outdoor all-in-one solutions that use an intelligent heat exchanger and other energy-saving and temperature control technologies to create a low carbon footprint and compact solution that occupies up to one square meter of space.
Due to its compact size, the solution could be set up on a rooftop or by the street. It provides operators with a way to overcome challenges related to site-acquisition, high levels of energy consumption and site construction in extreme temperatures.
SoftMobile solutions suite
Huawei also released its SoftMobile suite of solutions which have been developed to optimize network architecture, achieve dynamic resource sharing, and improve user experience. The solution of macro-macro and macro-micro coordination can decrease interference between sites. Macro-macro coordination can improve the site throughput. And network capacity can be improved with macro-micro coordination.
MWC visitors were able to see live demonstrations of Networker, Huawei’s user-side application for Monetizing QoE (Quality of Experience), which can be easily installed in smart terminals. Using Networker, visitors can see real-time displays of current data rate, available data rate, volume quota, and subscription status. The Networker software solution encourages users to upgrade their subscriptions for higher bandwidth, volume top-ups, and temporary boosts of speed via one-touch purchases.
Also introduced was the concept of Cloud EPC, Huawei’s concept for the future evolution of packet core networks operating on three layers: infrastructure, virtualization, and applications. The infrastructure level involves the modularization, unification, and standardization of underlying facilities to improve capabilities and performance; the virtualization level supports multiple logical network elements to dynamically share the infrastructure layer’s network resources; the virtualization layer utilizes an open API (Application Programming Interface) for the application layer to facilitate mobile broadband service innovation, accelerates development cycles of third-party applications, and helps improve QoE.
