Sao Paulo Policia Militar Improves Video Surveillance, Saves Money with LTE

By Mae Kowalke

 

Video surveillance is one technology that law enforcement officials increasingly rely on use to protect public safety. But, traditional hardwired systems are expensive, time-consuming to set up, and often produce unreliable results.

As an alternative, agencies in the U.S. and elsewhere are turning to 4G LTE (Long Term Evolution) networks for the creation, deployment and expansion of sophisticated video surveillance networks.   

A good example is Polícia de Estado de So Paulo (São Paulo State Military Police)—the agency charged with crime prevention, order maintenance, traffic control, and firefighting in Brazil’s most populous state.  As highlighted in a recent article in the Alcatel-Lucent (ALU) e-zine LifeTalk, it has been experimenting with an ALU supplied LTE network.

Balancing Security and Privacy Using 4G LTE Enabled Video Surveillance


By Mae Kowalke

When it comes to public safety, how much oversight and surveillance is enough, and how much is too much? Where do you draw the line between safety and invasion of privacy? These are questions policymakers and law enforcement officials struggle with every day. There are usually no easy answers.

A good starting point is to look at the role technologies like video surveillance can play in public safety, and what applications such technologies are most effective for particularly for providing an adequate degree of situational awareness.

Video surveillance is very prevalent in the U.K. where the typical person is recorded 20 times a day.  It is gaining ground in the U.S. where post-9/11 has made people feel less safe and created a desire to have their “guardians” always watching in public spaces. However, omnipresence for the sake of security has a price. It does invade personal privacy. 

This concern has only grown as sophisticated video and network technologies like 4G LTE— which is increasingly the technology of choice for massively deployed machine-to-machine (M2M) monitoring solutions— enable video can be not just automatically captured but also quickly analyzed to, for example, use facial recognition to ID a person or check a license plate against records in a database.

Improving Network Efficiency with Preloaded evolved Multimedia Broadcast Multicast Service (eMBMS)

By Mae Kowalke

One of the challenges faced by mobile network service providers deploying 4G LTE (Long Term Evolution) is using it to deliver popular multimedia content to a mass audience in the most efficient and effective manner. In the past, operators had two options: unicast or broadcast.

For those unfamiliar with the terms, below is a brief description of each:

  • Unicast — the sending content to a single network destination, with a unique address.  It is a one-to-one method of distribution. Traditionally, unicast has been when each individual recipient wanted or needed different content.
  • Broadcast — as the name implies, is sending the same content to all possible destinations, e.g., it is a one-to-many or one-to-all method of distribution. The obvious downside of broadcast is that everyone receives identical content.

Recently, a new technology call evolved multimedia broadcast multicast service (eMBMS) entered the scene.  It makes possible the efficient broadcasting of content only to interested recipients. An added attraction is that eMBMS is highly scalable.  It uses only a fraction of the capacity compared with unicast. This gives operators the best of both worlds: the flexibility of unicast and the efficiency of broadcast.

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.

Mobile Application Assurance: The Ideal Business Engine


By Susan Campbell

Many mobile services available to consumers today are perceived as commodity services. The assumption is that every provider offers the same thing at the same level of quality. The result is that those willing to go the extra mile in terms of customer service are often those deemed worthy of customer business.

This perception is driving a new focus in this space as providers seek methods for:

  • Improving monitoring
  • Personalizing the experience
  • Optimizing the network resources
  • Enriching the customer experience to drive loyalty

As captured in this Alcatel-Lucent (ALU) TechZine article, Mobile Application Assurance, the main focus for any service provider should be on advanced deep packet inspection (DPI) for doing the above.

It Takes a Village to Deliver Rich Communications

By Erin Harrison

As service providers (SPs) shift to all IP-networks, users expect features to become standardized.  This gives SPs an opportunity to provide their customers a new conversation experience.

A recent Alcatel-Lucent Enriching Communications article, “RCS Success Requires Community-based Ecosystem,” highlighted how the market for Rich Communications Services (RCS) has changed based on two developments that have converged — accelerating deployment of wired and wireless end-to-end IP networks and the rapid rollout and adoption of rich communications applications and services.

Voice over LTE (VoLTE) -- Starting the New Mobile Conversation


By Erin Harrison

 

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.”

Reducing Total Cost of Network Ownership with lightRadio Baseband Processing and Backhauling


By Beecher Tuttle

In order to succeed in the current wireless market dominated by bandwidth-hungry mobile applications, service providers need to find ways to expand network capacity while simultaneously reducing energy consumption and operating costs. This is quite a challenge to say the least.

Alcatel-Lucent's efforts in this area have resulted in some profound innovations, headlined by its new wireless networking paradigm, lightRadio™, which is designed to help service providers address growth and quality challenges.

The lightRadio technology family is comprised of innovations in antennas, radios and baseband processing, which combine to allow service providers to create next-generation architectures without the need to make complete infrastructure overhauls. Rather, lightRadio makes the most of existing wireless assets and capabilities to address cost, capacity and connectivity barriers.

Integrated Communications Addresses Smart Grid Challenges for Improving Energy Efficiency


By Beecher Tuttle

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.
