Heterogeneous Network Advantages
NEC on Heterogeneous Networks
Networks are never uniform because network environments are never the same. Each network is likely to include densely-populated metropolitan areas requiring differing degrees or types of public and business services. Networks may also cover more sparsely-populated rural regions, or a popular tourist destination or industrial center. Networks may also experience newly-identified dead-spots where users cannot get a signal, especially at cell boundaries.
NEC's intelligent Heterogeneous Network (HetNet) Solution is designed to address these diversified needs. NEC's HetNet combines NEC's high-capacity Small Cells with a multivendor-capable self-organizing network (SON) introduced into an existing network. NEC recognizes the need for flexibility, so our HetNet Solution can add cells of various sizes to existing networks with the same or separate spectrums. By doing this in the most effective and cost-efficient way, we can help you boost the available capacity in certain locations and provide uniform coverage in areas which are lacking.
Benefits of NEC's HetNet
The main benefits of NEC's HetNet solution are enriched capacity and guaranteed spot-free coverage. The overlay of Small Cells onto existing networks ensures high-speed, high-capacity communications for specific hot-spot area. This is especially desirable in densely-populated areas and business districts that need to provide reliable communication services to support an increasingly diverse and data-heavy range of applications. Our own studies show that HetNet can boost capacity and system throughput many times more than a conventional network.
Small Cells can also be placed over gaps between cells to fill dead-spots, or added along the network rim to expand the network. A uniform coverage is increasingly important in today's world with so many content-based applications and services. The ultimate aim of LTE is to provide tailor-made, high-quality, spot-free network provision, but there is still some way to go. NEC can help make this aim more achievable by combining Small Cell overlay with NEC SON suites that automatically manage interference between cells and other parameters and help optimize the quality of LTE services.
NEC's HetNet can also help maximize the cost efficiency of introducing a new network by providing cells of appropriate sizes from NEC's plug-and-play All-in-one Small Cell eNodeB to larger cells. This flexible choice of cell size allows LTE services operators to enhance or expand their networks with minimum investment. The eNodeB's simple site installation, automatic self-configuration and efficient network integration enables LTE service providers to implement quick yet error-free network upgrades.
NEC's SON for HetNet
NEC's Self-Organizing Network (SON) complements HetNet's ability to create the ultimate cost-efficient, quality network by ensuring full optimization and inter-network adaptability. SON facilitates the comprehensive automation of the HetNet from planning, implementation and optimization. SON's robust interference mitigation and mobility optimization are especially important features for resolving any problems that may arise when combining different cell sizes. The broad range of services available today brings in its wake huge diversity and volatile dynamics in terms of user behavior. HetNet with SON can effectively manage today's networks on behalf of operators, and improve the experience for users to the highest possible level of satisfaction.
