Tailoring 100G for Metro Networks
100G is in rapid fashion making its way across more and more of the network, as enterprises and carriers seek an extended break from bandwidth exhaustion and traffic bottlenecks. As the state-of-the-art technology has reached the metro, it has quickly spawned a more diverse landscape of solutions from which to choose.

The "Flattening Effect" and Network Intelligence
Because the network has simultaneously become both flatter and more complex, the journey toward a converged all-IP network comes with an entirely new set of network performance and management philosophies to be adopted and developed by IT organizations. To drive the need for maintaining and managing the experience of the subscriber, real-time monitoring, troubleshooting and provisioning of the network must be implemented strategically and methodically. Real-time monitoring of network traffic has proven to be crucial to diagnosing and analyzing network performance and services, and consequently the subscriber’s quality of experience (QoE).

Focus on a Premium Mobile User Experience
What is left for the service provider to differentiate themselves from their competition? It is the user experience. Since the playing field has been leveled for mobile devices, the most important thing carriers can do is focus on the user experience to create loyalty and drive revenue. Security is a big part of this picture.

What Operators Still Need in Next-Generation Transport
What do operators still need in next generation transport? This article will provide an in-depth look at what operators still need for next generation transport, and Packet Optical Transport Systems (P-OTS) in particular. P-OTS, thought well intentioned, has its weaknesses – and its early promises fell short of its expectations. We will discuss and focus on each of the challenges that exist in early P-OTS implementations by operators. Based on an assessment of these unique challenges, operators and vendors alike are gaining a better picture of what they really need, so that the full benefits of P-OTS can be realized

It's Time for Mobile-specific Encryption Policies
Imagine for a moment an attacker has gotten his hands on one of your employees’ smartphones. Perhaps it was forgotten in the backseat of a taxi or fell on the floor of a train on the way home from work. The attacker is able to get past the phone’s screen lock and password – 1234 wasn’t too hard to guess. Here's a look at things to consider when implementing encryption for mobile devices.

Video Grade Wi-Fi and the Emerging 802.11ac Standard
The emerging 802.11ac standard promises several big improvements over 802.11n, especially for video delivery in the home. This article looks at 802.11ac's performance enhancements, including wider 80 MHz bandwidth channels, use of 5 GHz spectrum, LDPC coding and beamforming, and multi-user MIMO capabilities. The first generation of 802.11ac silicon will be coming to market soon.

Safe SIP Trunking: New Security Requirements for Enterprise Adoption of SIP-based Services and Applications
As more and more applications and devices become SIP enabled --from deskphones to smartphones to tablets to softclients on any device – the move to SIP trunks promises to simplify the entire communications infrastructure for the typical enterprise adopter, centering on SIP as the common denominator across internal and external communication. Howeve, have you ever heard of vishing? Here we consider security implications.

Designing Small Cells and Remote Radio Heads for Next Gen Wireless
Traditional macro site architecture is being transformed with the introduction of remote radio heads (RRH) connected to a base station cabinet via fiber optic cables that can be distributed over 10 Km or more or smaller cells, both ways bring the users ”closer” to the base station. Here is a look at key elements of base station design, including digital baseband processing elements that define its users’ capacity, data throughputs, scalability and impact on equipment and operational costs.

Is the Quest for a CDN Strategy Paralyzing Carriers?
CDNs improve network performance, cut down on latency and deliver faster response times by distributing content to servers located close to end users. In the quest for an in-house CDN strategy, there is a hidden danger to carriers.

The Shift from SDH to a Packet-Based Network: A Look at the Transformation Undertaken by EnviaTel
EnviaTel, a German telecommunications service provider and Network operator for business customers and carriers, recently implemented a Packet Transport platform for three significant reasons: (1) the sharp rise in demand by business and carrier customers for packet-oriented services, (2) the continuously falling prices for these services, and (3) the inefficient and therefore expensive deployment of Ethernet services over the SDH network.

Setting the Record Straight on Location Tracking and Privacy
A so-called 'location-gate' controversy has raged over the revelation that Apple and Google tracked mobile subscriber location movements and stored that information in an unencrypted file on the handset that was potentially vulnerable to hacking and other attacks. The discussion should be refocused on how location and other sensitive information is protected, what it is used for, and the responsibility consumers have to make sure they understand how and why their location information is being recorded.

Reducing 4G/LTE Testing Time with Trial Acceleration
LTE trials usually involve a lot of repetitive cabling / un-cabling and configuration of both the test network and the device under test itself. A new method, called Trial Acceleration, helps service providers to get through the evaluation phase and to market faster, and it allows much more control when working with existing products and new software loads.

Solving the Mobile Video Puzzle on Today's Networks
An important piece of the mobile video puzzle throughout most of the world is the Third Generation Partnership Project’s (3GPP) 3G-324M protocol. While it does not yet apply to the U.S., most mobile service providers who understand the inherent challenges of deploying low-latency video applications with high service quality in a 3G network realize that it is important to focus on solutions that incorporate this protocol.

Policy 2.0: Smart Operators Increase Profit Without Rebuilding
Service providers need to look at how policy-based solutions in their networks can move beyond just dealing with pure cost control to revenue generation. Network-based policy solutions deployed to date have dealt with enabling basic service tiers and fair usage models in terms of QoS and monthly quotas. However they have largely been lacking in their ability to apply policy rules at a more granular service/application level or apply rich real-time context to the policy decisions being applied.

Mobile Video: Identifying Win-Win Pricing Plans
How valuable is video for mobile users? Would they be willing to pay more for video services that do not count against their data plan? If so, how much would they pay? Tekelec has conducted primary research that gauges user views regarding the relative value of mobile video as well as their reaction to various pricing models.

The Black Hole of 4G Indoor Wireless Coverage
Coverage gaps exist in metropolitan, suburban and urban communities in every wireless network. Research suggests that 20% of churn is caused by only 6% of the networks cell sites. Although coverage gaps can be isolated, they continue to exist despite technical measures, standard procedures, and other failed initiatives.
