In the U.S., it is no secret that there is a substantial customer as well political interest in seeing that under-served areas have access to state-of-the art communications networks. In fact, it can be argued that the data needs of such critical parts of the economy as agriculture and oil and gas exploration are as intense if not more so than those of industries in densely populated areas. Plus, the desires and expectations of families in the areas are no less important than they are to families in other areas of the country.
What all of this translates into is that while fiber optics and WiFi have allowed most Americans broadband access vast parts of the U.S. have remained under-served for broadband. All of that is changing. As the major wired carriers continue to fiber their franchise areas and the national wireless carriers rush to deploy 4G LTE networks, WiFi hotspots, femtocells, etc. Alcatel-Lucent has been leveraging the capabilities of its lightRadio™ portfolio of solutions to help mobile operators who serve less populous areas provide high-seed services to their customers at price points and performance capabilities that enable customers to enjoy the advantages of next generation devices and all the Internet has to offer in terms of content and applications. And, it allows the operators to do so at competitive prices and at a profit.
LTE Service Provider Solution: Reduce Cost, Increase Efficiency with Evolved Multimedia Broadcast Multicast Service (eMBMS)
By Mae Kowalke
Mobile network operators are always looking for new ways to more efficiently use their existing infrastructure without making large capital expenditures. With the explosion of tablets and smartphones, which will increasingly be used for a variety of video applications, streamed as well as interactive, use of a 4G LTE channel for delivering multicast services such as mobile TV is viewed as one way to do so. The reason is simple. It enables network operators to offer mobile TV without the need for additional expensive licensed spectrum and without requiring new infrastructure and end-user devices that might be required to unicast content.
A recent Alcatel-Lucent TechZine article, “eMBMS for More Efficient Use of Spectrum,” describes the enhancements to LTE specifications that have been standardized to accommodate rapidly changing user demands and concomitant network requirements. Evolved Multimedia Broadcast Multicast Service (eMBMS) is now a multicast standard for 4G LTE precisely because it allows one-to-many distribution of video content.

Most of us are familiar with the technology of Voice over IP (VoIP) – which simplistically is the use of the Internet Protocol to do voice communications over data networks that include the Internet itself. And, while most VoIP traffic has been over wired networks, a new voice technology is evolving called Voice over LTE (VoLTE) that is shifting the communications paradigm and enabling new services beyond traditional telephony over mobile networks.
In a recent article in Alcatel-Lucent’s Enriching Communications e-zine, The New Mobile Conversation Starts with VoLTE, author Edmund Elkin states that, “It’s no longer a question of whether VoLTE is the right choice for the new mobile conversation. It’s really a matter of determining when to begin the move to VoLTE, developing a migration strategy and selecting a partner to accompany them on the journey.”

Ever-increasing energy consumption, skyrocketing operating costs and pressure from regulatory bodies to help create a greener world have forced power utilities to reassess their delivery management methods.
The need for change – along with the recent influx of innovative network technologies – has led many utilities and distribution and system operators (TDSOs) to embrace the smart grid, a concept aimed at leveraging the power of next-generation networks to improve the efficiency and reliability of energy delivery and usage. The visibility and control provided by the smart grid enables utilities to match supply and demand, optimize delivery, cut operating costs and reduce carbon emissions.
In addition, a smart grid opens up a two-way communication system between utilities and customers, thus creating additional upsell opportunities and the ability for consumers to take a hands-on approach to energy conservation. Smart grid customers have access to their own webpage that details their energy consumption and the associated costs.
Deploying a smart energy grid is vital for utilities to thrive in the current environment, but it doesn't come without complications. TDSOs need to chose the appropriate technologies, understand their network requirements and make major decisions like if they should build their own communications infrastructure or lease it from a service provider.
Many of these questions can be answered by Alcatel-Lucent, whose Integrated Communications for Power Utilities solution is a proven way to take utilities into the 21st century of energy delivery and efficiency.
With its experience designing and deploying IP and LTE broadband wireless access networks, Alcatel-Lucent has a unique perspective on what is needed to get a smart grid initiative up and running.

As a service provider, what potential opportunities emerge if you were able to improve capacity, coverage and performance? With lightRadio technologies, you can gain support for current and anticipated wireless technologies that will address quality and growth changes; combine advancements in radios, antennas and baseband processing to support cloud principles, virtualization and architectural flexibility; and enable easy reprogramming and reconfiguration of network elements.
In this Alcatel-Lucent lightRadio Technology Overview, the innovations to address service provider challenges is explored. These challenges easily include adding more radios, antennas, towers and processing capacity; increasing spectral bandwidth; supporting new technologies; and making better use of cell site capacity. The development of lightRadio by Alcatel-Lucent focuses on optimizing total network costs over time so each wireless provider can make the most of their existing assets and capabilities.

The widespread use of smartphones, tablet computers and other Web-enabled mobile devices has caused wireless data services to explode. While this is good news for application developers and mobile device manufacturers, it presents several challenges for service providers whose networks see more bandwidth-hungry traffic each day.
This concern is compounded by the fact that the increase in traffic is surpassing the growth rate for wireless revenue. To survive, service providers need to decrease their cost per bit while simultaneously optimizing their LTE network to handle more traffic....
Bell Labs Helps Mobile Service Providers to Understand and Meet Video Calling Quality of Experience (QoE) Challenges
By Michelle Amodio
The explosive growth of smart mobile devices capable of making video calls is placing intense pressures on service providers to configure their networks to assure users have experiences that meet or exceed their expectations. However, providing a superior quality of experience (QoE) is a complex challenge.
As part of its support of mobile service providers around the world, Alcatel Lucent’s Bell Labs recently looked at the factors that influence QoE) to help service providers full understand all of the issues and what needs to be done to resolve them.
The questions the Bell Labs researchers explored were:
- What are the key factors that influence QoE for mobile video calls?
- Are residential broadband networks ready for them?
There was good news on both fronts. The challenges could be identified and categorized in terms of importance, and viable solutions can help operators meet consumer expectations in a timely and cost effective manner, as well as lay the foundation for new profitable services.
The main finding of the researchers was that service providers require not bigger (more bandwidth) networks but faster ones (in terms of response time). They validated that speed, combined with the proper provision of a consistent quality of service (QoS), are the critical determinants in mobile video calling QoE.
