Network Interconnection and Evolution for Super Carriers
|
|
In the Telecom world, the term "super carrier" refers to the largest telecommunications providers which own multiple, geographically separated, heterogeneous wireless and wired networks. As most super carriers have grown through acquisitions, they often operate a patchwork of network technologies and protocols, including both TDM and IP, across various regions. And with the advent of technologies such as 4G, super carriers are hastening to move to an all-IP core network. To remain competitive in today's market, super carriers must lower costs and continue to support existing services while moving to newer, IP-based technologies. In order to accomplish this, network interconnection is key.

Carrier Challenges for Tomorrow's Connected Enterprise
|
|
More and more office equipment -- printers, whiteboards, monitors, projectors, cameras, etc.-- is being used by employees remotely, whether they’re in the office or not. And technology is already coming to market to enable "smart" meeting rooms that will interact with the people meeting in them whether or not they are physically present.

Dynamic Performance Management for Mobile Data Networks
|
|
Most wireless data networks are being managed in a "static" fashion. On the "supply side," network management systems and drive tests provide snapshots of congestion and quality levels, and capacity is then allocated to maintain target performance and utilization levels. On the "demand side," traffic can be managed in two ways - Through pricing plans, which can increase or decrease usage based on their structure, or through policy management, which is currently based on core IP traffic consumption by end-users and devices.

To 4G or not to 4G: Supporting Exponential Mobile Traffic Growth
|
|
We often hear debates about the best 4G access technology, typically framed in terms of LTE vs. WiMAX. While there are technical differences between the two in terms of maximum peak user data rates (often touted through demonstrations on unloaded test networks), these access technology differences are of secondary importance when it comes to what really matters to subscribers. In order for users to experience 4G services that are not just incremental improvements on 3G, there must be major increases in typical user data rates, as experienced on actual loaded networks. Consider the networks.

Top Ten Considerations for a Successful Evolved Packet Core Deployment
|
|
The Evolved Packet Core (EPC) is the next generation multimedia core network for 4G access and is required to deploy LTE radio technology. It provides optimized access for 2G, 3G, non-3GPP and potentially even fixed access networks. Here are top 10 considerations to analyze when deciding your architecture, deployment strategy and vendors.

Going Green by Reducing Watts: A Step by Step Guide
|
|
As an industry, we waste a ton of Watts and generate a lot of smoke to move packets around. By some estimates, IT comprised 2% of world’s emissions. While at first glance this figure might seem small, it is in fact on par with the CO2 produced by the airlines. Reducing Watts is an area that IT can get a handle on and one that can have the greatest amount of impact.

The Basis for Advanced Broadband Services: Deep Session Inspection
|
|
Most broadband facilities are used to carry a single service in which all packets are treated identically. This is consistent with the original "end-to-end" design philosophy of the Internet as well as more recent policy statements by regulators. But both the internet design philosophy and regulatory positioning reflect a world in which all applications are fundamentally similar in nature: data applications able to withstand packet loss and placing no demand on the network in terms of latency or latency variation. But this is no longer the world we live in. And this is where deep session inspection (DSI) comes into play.

Ethernet-based Access in Fiber-to-the-Home
|
|
The fiber access build-out tsunami is swelling. Today more than 750 million households connect over copper and only 20 million over fiber. While it will take years to make a full transition to a fiber-based infrastructure, a rapid transition is in progress. There will be a mix of several technologies (EPON, GPON, 10G PON, WDN-PON, Active Ethernet, LTE, HFC) fighting for Ethernet-based access deployments.

Carbon Neutral Networks -- The ICT Sector Goes Green
|
|
The ICT sector, as one of the world's leading business sectors, has a global responsibility to ensure that its networks are carbon neutral. One of the ways by which a carbon-neutral environment can be achieved is by utilizing multi-service platforms, rather than single-purpose equipment in the network.

Wireless Backhaul Addresses the Broadband Stimulus Challenge
|
|
The economic stimulus funding for RUS and NTIA will drive tremendous broadband service deployment to rural and underserved areas in the next few years. Delivering broadband services will create a huge backhaul challenge, especially in the RUS case which is targeted at rural areas, with limited backhaul infrastructure. Microwave backhaul is expected to deliver a solution for this backhaul, but there are many considerations that will be important to delivering a successful Microwave backhaul network for this application

Thinking Broadly About Broadband Stimulus
|
|
The new broadband stimulus package provides important opportunities for people in unserved and underserved areas to reap the many benefits of high-quality broadband services. The question on everyone’s mind, of course, is how to make best use of the $7.2 billion in funds that will be committed to broadband projects over the next 18 months

Sustainable Mobility: Strategies for Green Wireless
|
|
The evolution of mobility technologies has allowed us to do things faster, smarter, and cheaper. Mobility and wireless technologies increase employee productivity by virtualizing the collaborative experience. Employees can move between workspaces while remaining connected to their colleagues and information systems. Yet an often overlooked aspect of mobility is the benefit it brings in helping businesses reduce their carbon footprints.

Location, Location, Location: <br>The Future of Lawful Intercept
|
|
Imagine a group of criminals embarking on a crime spree throughout a city. Using mobile phones they coordinate their actions from miles away, sharing information to evade law enforcement agencies (LEA) and map out an escape route. But there’s a twist. The LEAs are well-coordinated as well, quickly securing a warrant to tap into the criminals’ wireless communications. In addition to listening in on their conversations and data transmissions by intercepting them, the law enforcement agency is able to precisely pinpoint the locations of the handsets sending and receiving the transmissions.

Next Generation Wireless and 802.11n: Enabling the Video Experience
|
|
While 802.11a/b/g networks face capacity constraints when it comes to video, next generation wireless networks alleviate this constraint. Based on the new 802.11n protocol, the capacity of next generation wireless networks increases to up to 200Mbps with a data rate of 300Mbps. This addition of up to 9x in capacity easily provides the additional capacity for video applications. However, 802.11n presents additional benefits beyond client throughput and network capacity. Here's a look.
