Service assurance in mobile backhaul networks

As some of the world’s leading mobile operators continue to remind us in their quarterly results, the roll-out of packet backhaul has been key to mitigating potential cost escalation associated with the transition from a voice centric to a data centric revenue model in mobile services. Many operators that are making that transition successfully draw attention to the critical role that is being played by the transition to packet backhaul...for the full article click here

Wholesale backhaul and the switch to carrier Ethernet: InfoVista one-on-one

It is quite apparent that the mobile backhaul industry is in a transition from legacy TDM transport network infrastructures to that of carrier Ethernet.  This transition is fueled by the increased use of data-hungry devices that demand more bandwidth, as well as the advantages of deploying carrier Ethernet services (i.e. scalability, flexibility and cost). TelecomEngine got a chance to speak with Juan Prieto, Product Marketing Manager at InfoVista, about the perspective from both Mobile Operators and wholesale providers transitioning to carrier Ethernet transport.

Delivering on the 4G user experience promise with micro-cellular networks

Global mobile data growth is driving innovative solutions from service providers that include everything from billing schemes to technology solutions.  This accelerated growth of mobile data traffic is being fuelled by the continued advancement of smartphone and “superphone” technology and the advanced applications they enable. Additionally, picture and video intensive networking, including social networking, have further compounded capacity demands on mobile networks.

Sprint confirms iPhone, concerns linger

Reuters

Sprint Nextel (Overland Park, Kan., U.S.A.) confirmed that it will sell the next version of Apple Inc's (Cupertino Calif., U.S.A.) iPhone, ending months of speculation about whether it would become the third U.S. operator to sell the device.  While carrying the device should help Sprint keep subscribers from fleeing to other operators, some analysts worried whether the costs would outweigh the benefits because Apple phones come at a steep premium to other devices.

Improving performance of 3G and 4G networks with the Diameter Agent

While their predictions may vary, virtually every industry analyst foresees staggering growth in mobile data in the next five to ten years. ABI Research expects a 39% compound annual growth rate from 2011 to 2016 in mobile data traffic. Looking out to the year 2020, Jeffries forecasts a 100x ramp in mobile data, and, the firm admits, that’s likely a conservative estimate. Faced with this looming data deluge, operators are turning to all-IP networks like IMS and LTE, which rely heavily on Diameter protocol, to move and monetize their data traffic. 

Diameter routing in 3G, IMS and LTE networks: Tekelec one-on-one

Mobile data traffic is increasing at an enormous rate, which is driving many mobile operators to switch from a 3G network to all-internet protocol (IP) network, such as LTE, to manage the high volume of traffic.  The Diameter protocol, which is used on most IP networks, plays a central role in the management of 4G LTE and IMS networks and 3G charging and policy deployments.  TelecomEngine spoke with Jason Emery, Director of Product Management at Tekelec, to discuss how its Diameter Signaling Router (DSR) product supports multiple networks, including LTE, through the centralization

Telecom companies lash out at EU Fiber proposal

Reuters

 Telecom operators hit out at a new European Union proposal that aims to spur investment in faster fiber optics networks by reducing profits generated on copper-based networks, saying it was wrongheaded and would actually stunt progress.

Executives from nearly a dozen companies, including France Telecom (Paris, France), Telefonica (Madrid, Spain) and Telecom Italia (Rome, Italy), came out against the proposal only minutes after EU Commissioner Neelie Kroes laid it out in a speech at an industry conference in Brussels on Monday.

Improving Performance of 3G, IMS, and LTE Networks with the Diameter Agent

The Diameter protocol defines a new network node - the Diameter agent (DA) – which operators can leverage to create a Diameter signaling layer in IP networks. This paper looks at how to improve the performance of 3G, IMS and LTE networks with the Diameter Agent.

Europe slow to adopt 4G mobile: sector executives speak

Reuters

Europe's rollout of fourth-generation mobile networks is trailing major operators in the United States and parts of Asia, which are already offering the service to millions of customers.

Report: small cell backhaul to shift away from copper, fiber toward wireless

According to the recent report "Mobile Backhaul for Small Cells" by research firm ABI Research (Oyster Bay, N.Y., U.S.A.), by 2016 an estimated 58% of outdoor small cells will be backhauled using wireless techniques.
