Why SingleRAN is becoming ubiquitous TextStart Huawei's SingleRAN is revolutionizing the global mobile communications industry to the benefit of operators and end users worldwide. Operators today face an inevitable overlap. Anticipating and responding to the burgeoning demand for mobile broadband (MBB), LTE is emerging faster than expected, while GSM and UMTS continue to meet the needs of the vast majority of the world's mobile subscribers. To support three coexisting modes, GSM, UMTS, and LTE, traditional models call for three sets of equipment and three networks, placing major pressure on operators from deployment to operation and maintenance (O&M). Issues such as repeated equipment investment, continuous site upgrades, and the inevitable complexity of O&M only add to the overlap headache. The cause and the cure are both found by addressing the true requirements of MBB. MBB is all about smart thinking: decreasing network update investments while increasing the intelligence of the same to improve end-user experience. Using an integrated network to realize the features of MBB, such as HSPA+/LTE, will help operators effectively and flexibly tackle the aforementioned challenge. But then, as the new industry gradually matures, the inevitability of escalating market competition compels a return to a recurring fundamental question: How can we more efficiently utilize assets? Huawei worked with leading operators to conduct an in-depth analysis of what really mattered most, and found the most important to be site, spectrum, pipeline, user and staff assets. Fortunately for carriers around the world, protecting and maximizing the value of these and other assets is achievable. Huawei's SingleRAN solution comprehensively assists operators in achieving maximum asset utilization by transforming various technical modes into the advantages of just one radio access network. SingleRAN also allows operators to distance themselves from the technology and equipment layers and consider network development strategies in terms of true end-to-end O&M efficiency. SingleRAN turns GSM, UMTS, and LTE into features Huawei introduced the SingleRAN solution in 2008 to adapt to rapidly evolving telecommunication networks. At the core of SingleRAN is convergence, allowing operators to easily accept and assimilate continuing technological innovations. Huawei's SingleRAN provides an integrated BTS, BSC, O&M management and site solution, supporting the convergence and evolution of different technologies. From an operator's perspective, SingleRAN substantially lowers OPEX and decreases risks conventionally associated with new technology selection and network evolution; helping to simplify strategy decisions and cost duplication related to the selection of varied technical modes through the deployment of multiple RANs. With these objectives in mind, SingleRAN is becoming the simple, single decision of choice for leading operators around the world. Over the past few years, Huawei has continuously worked to promote network convergence, ensuring the SingleRAN solution provides end-to-end support for integrated network deployment and O&M. As a result of this ongoing dedication, Huawei's SingleRAN solution also includes a series of new products such as integrated multi-mode BSC, SDR-based RRU with dual-transmitter capability and SingleOSS, significantly strengthening and enhancing the convergence of multi-mode mobile networks. Huawei's SingleOSS products provide co-management for multi-mode mobile networks and greatly increase O&M efficiency. In today's fast changing and highly competitive environment, operators must be able to respond quickly and in a cost-effective manner. From network deployment, to choosing between various modes changes and between different features of the same network, SingleRAN offers precisely the flexibility that is needed. Operators can choose different features according to the stages of market development. At the equipment level, SingleRAN realizes one network supporting multi-mode deployment. SingleRAN also enables comprehensive integration of GSM, UMTS, and LTE features. All features can be deployed within the same network and resources including spectrum, PA, and O&M can be dynamically shared for greater effect and greater efficiency. With SingleRAN, only one integrated management system is required for all deployments, regardless of whether GSM, UMTS, or LTE. In place of three, just one team is now required for seamless O&M of a multi-mode network. Thus, SingleRAN is both simple and smart. SingleRAN maximizes the efficiency of key related assets Site assets: Broader, closer, and greener As emphasis on private property rights and environmental protection continues to increase, the implications of appropriate site acquisition become more challenging. When considering multi-network deployment, the cost of leasing sites across numerous countries and regions is prohibitive and far exceeds that of purchasing equipment. Looking to maintain existing customer loyalty cost-effectively while profitably expanding business bases and attracting new users, operators clearly need to enhance and expand network coverage, but only if the construction of new sites can be kept to an absolute minimum. To this, has to be added the need for minimal disruption of any existing site without which lease terms can be broken, and legacy sites lost. In response, Huawei's SingleRAN solution addresses three critical site development criteria: broader, closer, and greener. In a world where rapidly increasing data rates represent a tremendous challenge for mobile networks, broader efficiencies are mandatory. With Huawei's SingleRAN solution, mobile networks minimize the need to add new sites or disturb existing leased space. With a much smaller footprint than any traditional BTS, just one SingleRAN site or cabinet supports five frequency bands and three modes, providing high capacity and high power with much more efficient resource management. This assists wireless operators worldwide in achieving ultimately efficient single-network deployment of GSM, UMTS, and LTE as well as single-network O&M. Through SingleRAN's "broader" features, operators are able to more easily meet the challenge of rapidly increasing data rates. "Closer" refers to using Huawei's femtocell pico technologies to supplement any mobile network, bringing deployment and applications closer to users. As data rates exponentially increase, femtocell pico also help reduce the pressure on the network by sharing the ever expanding load. "Greener" means lowering the power consumption of sites from year to year through technical solutions. Huawei technologies, such as IP microwave backhaul, can also substantially reduce the cost of site construction. Spectrum assets: Increasing efficiency With the majority of spectrum already allocated, an operator's existing spectrum resources largely dictate its competitive strength. And with a scarcity of available spectrum, operators wishing to purchase additional spectrum resources must spend exorbitant sums of money. The ideal solution is for operators to leverage extant spectrum resources to deploy different modes of mobile networks or reuse legacy spectrum resources as new generations of networks evolve. Only in this fashion will operator spectrum resources become a continuous source of profit while also gaining in value. With this well-documented need to protect and enhance spectrum assets in mind, Huawei's SingleRAN solution improves spectrum efficiency through two key techniques. Multiplication: Multiple-Input Multiple-Output (MIMO) technology achieves improved spectrum efficiency. The majority of Huawei BTS products are currently being optimized to support MIMO, with single modules supporting two transmitters. Coordination: Huawei's SingleRAN supports and coordinates deployment of GSM/UMTS, UMTS/LTE, GSM/LTE, and GSM/UMTS/LTE over shared frequency bands. Huawei's multi-frequency, multi-mode Software Defined Radio (MFMMSDR) can also be used to increase spectrum efficiency. In the near future, Huawei's MFMMSDR will also support combinations spanning across technologies and frequency bands. User assets: Providing five billion users with the perfect experience Users are clearly an operator's most precious asset. As mobile networks continuously evolve, loss of users during a network upgrade process is the greatest risk facing operators. Ensuring smooth network evolution and maintaining a level of service that satisfies users becomes a topic of utmost concern. Despite rapid development of data services, voice remains at the core of mobile service. Consequently, SingleRAN continues to focus on and improve the experience of the five billion voice service users worldwide, working to ensure crystal-clear sound quality. Working with our operator partners, Huawei is carefully leading users into an age of rich mobile broadband communication while ensuring the combined development of data, voice, and GSM/UMTS services. As LTE becomes a more widespread reality, high-quality, seamless connections will become the norm, providing an always-on and always-connected experience. As a true end-to-end solution, Huawei's SingleRAN is all about end-user experience. The management systems help operators quickly respond to user complaints, precisely locate and resolve issues, and continuously improve user satisfaction. Staff assets: Increasing productivity without added cost Skilled engineers, network management and maintenance employees are a major asset for all carriers but, when added human resources are required for improvement of network performance and capacity, these same assets also create added pressure in the form of increased payroll, benefit and liability costs. In this fashion, a final primary concern of operators relates to avoidance of any large-scale growth in personnel while enhancing existing networks and expanding for future growth. Huawei's SingleRAN solution assists operators in achieving integrated management of equipment and sites, of various modes of technology, and of the entire end-to-end network without challenges to human resource overheads. This same integrated management system allows integrated O&M of GSM, UMTS, and LTE networks, which lowers OPEX while increasing the efficiency of CAPEX. The same integrated O&M also includes a valuable transition of focus from equipment alone to O&M responding to and enhancing the experience of users. Huawei also stands at the forefront of self-organizing network (SON) technology. Early in the second quarter of 2009, Huawei announced a SON commercial solution, forming an important component of Huawei's leading LTE solution package. SON is a crucial aspect of LTE network technology, allowing LTE networks to achieve self-configuration, self-optimization, and self-recovery. When the network topology changes, Huawei's SON technology ensures network connectivity and maintains optimal network performance. In addition, it reduces the complexity of O&M operations, lowers skill requirements for O&M staff, and lowers the costs stemming of network planning, optimization, and deployment. Looking ahead, the accelerating application from Huawei's SingleRAN solution will contribute to a world where integrated mobile networks will become ubiquitous and SingleRAN will also be essentially responsible for helping operators realize future network experiences such as HSPA+/LTE. Supporting our prediction and the viability of Huawei's SingleRAN, as of Q4 2010, Huawei had deployed more than 80 SingleRAN networks for leading carriers including Telefónica O2 Germany, Telenor, Net4Mobility and TeliaSonera.
