This Month’s Issue

Continually measuring the Key Performance Indicators (KPI’s) of the SLA’s being delivered in backhaul networks, is critical to the successful execution of the delivery of Ethernet mobile backhaul services. This month we’re excited to publish a case study of SureWest Communications experiences delivering their Wireless Carrier Backhaul Service to some of the top tier wireless operators. Performance assurance is a fundamental requirement for success in this growing market for Carrier Ethernet services and you’ll learn how SureWest evaluated the Accedian Networks Performance Assurance solution and hear about their experiences deploying it in their network to support both their Wireless Carrier Backhaul and business grade EtherMAN services.

Next up to help prepare for the migration to 4G LTE networks, Accedian has recently published our LTE Performance Assurance Handbook. The handbook provides a comprehensive look at the 4G network technology, architecture and components and examines the implications of each on the backhaul networks that will so critical to the successful migration to 4G. A short video will walk you through the contents and provide a preview of the technical content inside.

Finally, we’re proud to announce the General Availability of our much anticipated MetroNODE 10GE™ platform. Introduced several months ago, the MetroNode is the most powerful Performance Assurance Agent in the Accedian product family. This scalable, high performance NID is now available for deployment in a variety of demanding Performance Assurance applications.

Application Highlights

Accedian recently announced during the Light Reading Mobile Backhaul Convergence Conference that SureWest Communications is deploying Accedian Network’s Performance Assurance Platform to ensure high quality service delivery for its Wireless Carrier Backhaul Ethernet-based mobile backhaul service.

Wireless Backhaul

The explosive growth of smart phones and mobile broadband devices, coupled with the deployment of next generation mobile broadband applications, is creating a demand for bandwidth that simply cannot be met using the legacy mobile backhaul networks. Existing wireless backhaul networks originally designed for voice have a typical capacity of 1-3 Megabits per cell site and do not accommodate the onslaught of broadband data traffic, where mobile operators are seeing demand for 10-50 Megabits per cell site. SureWest’s fiber and Ethernet-based networks in both the greater Sacramento and Kansas City regions are more than sufficient to meet this demand.

SureWest’s Wireless Carrier Backhaul is an Ethernet-based service that provides the capacity and performance needed for wireless operators to effectively deliver mobile broadband services. Delivering Ethernet mobile backhaul services can be challenging as the mobile network demands precise service quality. Monitoring latency, packet delay variation, packet loss and availability of mobile backhaul services is critical to successfully meeting the wireless operators’ needs and requires robust performance assurance to ensure that the mobile backhaul network meets these needs around the clock.

Wireless Backhaul

Before deploying the MetroNIDs in the SureWest network, SureWest compared them against a number of alternatives. The decision criteria included not only performance assurance monitoring and reporting features, but SureWest also compared performance, interface density and power consumption. All aspects for deploying the most efficient service performance infrastructure were evaluated.

Watch an overview presentation of Accedian’s new LTE Performance Assurance Handbook which covers all aspects of LTE backhaul testing, monitoring, SLA reporting and maintenance. This comprehensive technical guide features detailed information on the performance requirements and objectives for successfully providing mobile backhaul services for LTE mobile platforms. It contains extensive references to ITU, IEEE and MEF standards along with in-depth explanations of key technologies are illustrated with extensive network and engineering diagrams.

Will Apple Be First to Make the Video Calling Breakthrough?

Will Apple Be First to Make the Video Calling Breakthrough?
Lots of people will point out that person-to-person video calling appliances and features have been available for a while. Most of us would point to Skype, while others would point to the capabiltiies Nokia has been offering on its high-end phones, or the specialized video telephony products now on the market.
Apple’s new  iPhone 4 “FaceTime” video calling feature might be notable, though. People will have different opinions about the ease of use for Skype video telephony, but the big snag for most consumer video telephony appliances has been the need to buy them in pairs.
The iPhone 4 might be the first “appliance” supporting video telephony that does not actually have to be “bought in pairs,” given the huge installed base the device is likely to have, globally. The other angle is that video telephony could become a “mere feature” of the most-widely-used communications appliance on the planet, though of course for the moment only on Apple iPhones from version 4 and forward.
Video calling might be a social function and therefore there is a network effect not possible when the units are deployed pair by pair.
Some significant sub-set of the mobile user population uses iPhones. In my own family, for example, all four of my children use iPhones, and it appears iPhone use among their peers is just about that high.
By confining FaceTime sessions to Wi-Fi connections, Apple avoids the almost-certain uneven quality of experience users would experience on AT&T’s 3G network.
Innovations sometimes, perhaps ever, solely or primarily dependent on development of new technology. More commonly, it is a combination of ease of use, user installed base, price and the face that lots of other people seem to be doing it. Up to this point, almost no users had to worry about “everybody else doing it.” That could change, beginning with the iPhone 4.
The bandwidth implications are clear enough. FaceTime only works when users are on a Wi-Fi (fixed line access) connection. That keeps the video bandwidth off the mobile network. Whether that stance can be maintained forever is questionable, though it also likely means service providers will be able to charge extra for the ability to use FaceTime on the mobile network.
Restricted to Wi-Fi, FaceTime is alot like Skype, a scheduled experience that does not represent unfettered, use it whenever you want communcations mobile text, texting and messaging represents. To make video telephony as natural as voice calling, FaceTime will have to be enabled for any-time mobile use.
Still, the direction is clear enough: The iPhone 4 supports high-definition video, pixel resolution that actually is higher than what the human eye can discriminate and is getting Netflix. That means more video, and more video means more backhaul. Some amount of usage can be offloaded to the fixed network, but video telephony won’t become mainstream until users can just use it, anytime they want.
