WCDMA/HSPA enables hundreds of millions of people to access mobile broadband (MBB) through their smartphones every day as part of their daily lives. Today, new, low-priced WCDMA/HSPA smartphones are entering the market, and they will enable MBB for new hundreds-of-million-sized markets.
A holistic methodology is necessary for assessing the potential reductions of CO2e emissions. Life cycle assessment (LCA) is a well-established method and can be used for comparing emissions created in different scenarios.
Delivering additional radio-network capacity and coverage through the deployment of small cells as part of a heterogeneous network is central to most mobile operators’ mobile-broadband strategies, and Wi-Fi is a key element to satisfying the hungry data appetites of millions of smartphone and tablet users.
As the Networked Society takes shape, providing the right user experience is a top priority for operators. Bandwidth-hungry applications common on smartphones, tablets and other connected devices are driving figures for data traffic sky high. The opportunity for operators arises from people, business and society depending on their devices, mobile broadband access and high-performance networks. Heterogeneous networks, commonly known as hetnets, are efforts to improve and densify existing mobile broadband infrastructure together with added small cells are important when meeting ever-increasing user expectations.
A decade ago wireless technology was dominated by mobile telephony. Today, there are around 5.8 billion mobile subscriptions. In the US market, for example, LTE networks cover more than 50 percent of the population and this figure is rapidly increasing. LTE enables an ever-widening range of services, enhanced QoS, efficient use of resources and flexible spectrum utilization. All of this in turn creates a wealth of new business opportunities, leading to tougher competition among service providers and application builders. Applications using highly accurate wireless-device positioning are constantly being developed and enhanced. This increases user expectations, which consequently creates demand for smarter services.
Deploying mobile broadband in 1800MHz spectrum is part of the solution to the rapid growth of mobile broadband, which is forcing operators to add both coverage and capacity, applying a holistic spectrum strategy that covers voice-centric and mobile broadband network deployments. As the penetration of 3G-capable terminals increases, the 1800MHz spectrum used for GSM services becomes an increasingly attractive candidate for refarming to mobile broadband services based on LTE and HSPA.
Many mobile operators around the world have HSPA technology to thank for their mobile broadband success. But as subscription rates continue to rise at incredible rates, fed by huge smartphone sales and the demand for bandwidth-hungry data, mobile operators face increasing challenges to keep their customer bases satisfied. HSPA evolution provides a cost-efficient answer.
As network operators seek to differentiate their broadband offerings, manage traffic and optimize operations across fixed and mobile access networks, policy control has a central role to play. Implementing a converged end-to-end policy control solution in broadband networks reduces operational complexity, enhances subscriber retention and creates opportunities for cross-bundling of services.
The internet, the number of internet users, the volume of mobile devices, and the number of constantly connected devices have been growing at a tremendous rate, a trend which is set to continue far beyond the original growth expectations for which the network is designed.
