Ryan Ding, senior vice president of Huawei, announced just ahead of this year’s Mobile World Congress that: ‘At this year's MWC, Huawei will further define the increasingly connected world, illuminating the fact that the experiences and possibilities of a connected lifestyle are infinite. As a leading global ICT solutions provider, Huawei will remain committed to meeting customer needs, focus on the pipe business, and provide operators with pipes that have a diameter as wide as the Pacific Ocean.’
In order to embrace the new era of big data, big traffic, and big wisdom together with customers, Huawei is focusing on providing high-traffic pipe systems capable of carrying big data and keeps the pipe in mind when deciding on product and solution portfolios. The pipe is part of Huawei's strategy to meet the challenge of future data floods, and represents Huawei's major growth source. At MWC 2013, Huawei showcased the following solutions, flagship products, and services:
Huawei's ICT network architecture that is built on cloud computing and software-defined networking (SDN). As a core part of Huawei's pipe strategy, SoftCOM features such core concepts as network-level cloudization, equipment-level cloudization, telecom IT cloudization, and Internet-oriented operation. By capitalizing on cloud computing revolutions and Internet-oriented operation models, the SoftCOM network architecture delivers two major benefits.
First, the architecture helps tap into more revenue sources by expanding IT services beyond networks, enabling traffic operations, and creating an open ecosystem. Second, the architecture can slash costs by structurally improving network utilization and operating efficiency.
Huawei's SoftMobile aims to redefine the design architecture for mobile broadband (MBB) network equipment and supports software-defined modular pipes of large diameter. SoftMobile can resolve equipment problems related to multi-mode and multi-frequency networking.
Therefore, SoftMobile is essential to building an MBB network with a diameter as wide as the Pacific Ocean. On-demand customization and collaboration are additional benefits. On the foundation of SoftMobile, the mobile industry will develop further and transition into a new mobile age with infinite connected possibilities.
In addition to leveraging the advantages of Huawei's SingleRAN offerings, SoftMobile makes full use of cloud computing technologies. Additionally, SoftMobile incorporates the core concepts of ‘unified scheduling and virtualization of resource pools’ and ‘on-demand service’ into MBB network architectures, network topology architectures, and business architectures.
In this way, SoftMobile can transform MBB networks into open software-defined networks. The SoftMobile-enabled transformations will help operators build profitable MBB pipes with enhanced elasticity, intelligence, scalability, and automation capabilities that address the ICT convergence.
Huawei demonstrated its latest SoftMobile-related solutions and products at MWC 2013, including SingleRAN Advanced, LTE, Voice over LTE (VoLTE), UMTS/HSPA, multi-service engine (MSE), and SingleOSS, all of which support software-defined products and service collaboration, while delivering larger capacity and better user experience. Huawei said that these solutions and products can help operators increase profits from networks and optimize user experience.
Baseband Unit (BBU)
Huawei said it is the first to launch a four-mode BBU (GSM/UMTS/LTE FDD/LTE TDD) that enables flexible software-defined configuration.
Blade Remote Radio Unit (RRU)
Huawei's Blade RRU supports different modes, frequency bands, and channels. Owing to its standard and compact designs found nowhere else in the industry, the Blade RRUs can be deployed easily. Many leading operators in Europe, Asia, China, and other countries and regions have successfully used the Blade RRUs for commercial purposes.
High-performance AAU (air plane access unit)
Thanks to its modular design (two frequency bands in one radio unit with an integrated antenna), the AAU boasts an integration level two times higher than the industry average, thus facilitating installation and maintenance.
Huawei said the AAU RF module is the only such unit to support 4x4 MIMO and beam forming to effectively improve network capacity by 85%. A single AAU module supports a reliably strong and consistent 1Gbps throughput.
The AAU is being tested by Vodafone UK, Deutsche Telekom, and other leading operators, and its ability to enhance performance by 50% is highly recognized by the operators. Huawei demonstrated AAU beamforming together with Vodafone UK at the show.
AtomCell: LampSite indoor coverage solution
The AtomCell was launched ahead of MWC 2012 and the company reports it has now been put into successful commercial use in more than 50 countries. The compact LampSite solution is designed to provide better indoor coverage using TD-LTE technology to offer Wi-Fi coverage in subway stations, shopping malls, office buildings, and other indoor scenarios.
LampSite includes a comprehensive set of BBU, RemoteHUB(rHUB) and PicoRRU(pRRU) products along with accompanying transmission solutions. The compact pRRU supports multiple bands and modes and can simultaneously support LTE TDD, LTE FDD, UMTS and GSM. A LampSite indoor coverage network can also be deployed simultaneously with Huawei’s SingleRAN solution.
Thanks to BBU’s baseband sharing feature, one fibre is used for several cells, saving up to 87% of fibre typically used for indoor deployments. rHUB connects to pRRU by cable, and support power over Ethernet (PoE) to simplify site construction and reduce total deployment costs.
In an early deployment phase, individual pRRU cells aggregate into one cell to reduce interference. Once the network offloads heavy traffic, the cells are split again and Adaptive SFN is enabled to balance capacity and interference. Huawei iManager system and evaluation tools are then used to accurately monitor and intelligently optimize indoor hotspot traffic.
LampSite is a part of Huawei’s SoftMobile solution for strengthening MBB pipe profitability, wireless network performance and user experience with ocean-like broadband, on-demand and orchestrated network capabilities. It has been commercialised by Softbank in Japan.
LTEHaul solution for mobile backhaul
This is a SDN-based mobile backhaul solution designed to provide end-to-end support for the planning, construction, maintenance, and optimisation of mobile backhaul networks that allows evolutions towards LTE.
By adopting the software defined networking (SDN) technology, the solution greatly simplifies the operation and maintenance (O&M) and management of mobile backhaul networks and shortens the time to market (TTM) of new services. The solution helps operators resolve network issues during the evolution to LTE networks.
However, three large gaps exist in backhaul networks that operators must leap over during the evolution to LTE and LTE-A networks. First, a large gap exists between massive LTE hotspots and limited hotspot backhaul sites. The LTEHaul solution extends the traditional backhaul network downwards to form a fronthaul, facilitating the management and maintenance of massive hotspot backhaul nodes.
A second large gap is present between the vast increase in the LTE bandwidth and the limited bandwidth on the traditional backhaul network. Third, there is a large gap between the traditional backhaul and core networks. The LTEHaul solution stretches the traditional backhaul network upwards to achieve end-to-end fast service provisioning, protection switching, and fault locating from eNodeBs to evolved packet cores (EPCs).
By addressing the large bandwidth and seamless quality service requirements of new LTE/LTE-A-oriented technologies such as eMBMS, COMP, and eICIC, the Huawei LTEHaul solution provides users with site-free and virtual service access. Meanwhile, the fronthaul, backhaul, and core are unified in the network structure, thereby overcoming the bottleneck of traditional GSM/UMTS network structure and bandwidth.
By leveraging the SDN technology, the network service bearing and control are separated, and far-end massive cell site gateways (CSGs) and small cell site gateways (SCSGs) can be managed on aggregation site gateways (ASGs). This significantly simplifies network management and O&M, saves the operating expense (OPEX) by approximately 60%, and facilitates fast service provisioning.
At Mobile World Congress, Huawei demonstrated several new LTE products of the LTEHaul solution, including the zero footprint small-cell mini router ATN 905 (available in both indoor and outdoor versions), antenna alignment mini microwave devices, mini PON, and an aggregation router that helps manage massive network-end backhaul devices. Using these products, the LTEHaul solution helps operators resolve network issues during the evolution to LTE networks.
