Increase wholesale mobile backhaul ROI with packet optical transport

Wed, 02 May 2012 09:24:37 -0500

A couple of big trends in the mobile broadband arena are coming together to deliver a one-two punch to service providers offering mobile backhaul service to wireless operators.

Signs of a greener spring

Tue, 24 Apr 2012 13:40:56 -0500

Going green has never been more popular, especially around Earth Day. More than a trend, good environmental performance helps build a stronger business.

At Tellabs we measure progress towards our goal, to reduce energy use and greenhouse gas (GHG) emissions with more efficient products and operations. We’re encouraged by some of the signs we see this spring:

IPv6 in mobile backhaul: a question of timing

Wed, 11 Apr 2012 09:45:26 -0500

It’s been evident for quite some time that the explosive growth in the number of IP-enabled mobile devices is exhausting IPv4 addresses. Thankfully, the next-generation protocol, IPv6, can support 2128 IP addresses —an almost limitless number of devices—each with its own unique IP address.

Optical LAN network architecture helps operators meet tangible green goals

Wed, 04 Apr 2012 09:31:00 -0500

Most of us want to be good stewards of the earth. We aim to minimize the negative impact on our water, air and land. We hope to provide a healthy environment for future generations.

However, often we do not do enough to bridge the gap between our intentions and actions.

Plan flexibility and scalability now to avoid LTE backhaul growing pains

Thu, 29 Mar 2012 08:29:00 -0500

LTE backhaul can enable mobile operators to deliver tremendous, wireline-like data speeds to their customers. To deliver this promise, operators first need to overcome many challenges. These challenges are truly unique, because LTE fundamentally changes the nature and requirements of mobile backhaul networks.

Making smart, sustainable choices

Mon, 19 Mar 2012 09:53:00 -0500

Some call it sustainability. Others use the term corporate social responsibility. The financial world prefers “ESG” (Environmental Social Governance).

No matter what you call it, more people are interested in how companies manage their business for positive economic, social and environmental outcomes.

IPsec protection brings backhaul security up to speed in IP-based LTE networks

Tue, 13 Mar 2012 08:51:00 -0500

Contrary to traditional TDM and ATM based 2G and 3G networks, LTE networks are based on IP connectivity. This technology offers more flexibility and cost-efficiency. But the architecture of LTE, combined with the open nature of IP, makes LTE networks far more vulnerable to attack than their TDM-based predecessors.

OIF interoperability: making OTN networks faster and more reliable

Thu, 08 Mar 2012 08:46:00 -0500

Since 2003, Tellabs has participated in tests on control plane interoperability with the Optical Internetworking Forum (OIF).

Control Plane technology automates the process for provisioning services across a network. It’s a crucial network function--operators need their control plane services to work across their entire network, where Tellabs equipment may not always be installed.

Syntonization and synchronization: essential for all mobile networks--especially LTE

Thu, 23 Feb 2012 02:00:00 -0500

As operators migrate to LTE and LTE-Advanced, mobile backhaul synchronization becomes more important than ever.

In 2G and 3G networks, mobile operators were able to syntonize base stations from native TDM networks. The nature of the backhaul network provided an easy source of timing. Today these mobile networks have grown, and most of the traffic is carried over Ethernet.

Network performance: are you getting the whole picture?

Tue, 21 Feb 2012 09:19:00 -0500

I always get excited around this time of year. As much as my romantic side enjoys the romance (and chocolates) around Valentine's Day, the geek in me gets happier towards the end of the month. Because it's almost time for Mobile World Congress.

This year Tellabs has something special to share, something that I know excites my fellow geeks: analytics.

ITSF conference puts synchronization in focus for 2012

Mon, 13 Feb 2012 09:43:00 -0500

Late last year, synchronization experts, including myself, gathered together at the ITSF conference in Edinburgh. Though we spent some time discussing our progress in 2011, we debated at length the issues we'll face in 2012. Here are the top four that I took away from the conference, in no particular order:

All-fiber networks: lowering costs and increasing revenues to accelerate broadband penetration

Thu, 09 Feb 2012 08:59:00 -0500

What's standing in the way of accelerating the deployment of all-fiber networks? In most cases, it's high costs and low opportunities for revenue.

The solution to this issue has eluded broadband service providers for years. That said, I foresee great improvements in all-fiber network economics. This is mostly due to the work done by the Gig.U initiative, and the advancements of Optical LAN technology.

How European operators are getting smarter

Thu, 26 Jan 2012 08:52:00 -0500

European mobile service providers are in a fierce competition. Voice and messaging revenues are down, and the number of new subscribers is slowing. Operators must compete just to keep their current subscribers.

According to Infonetics, mobile broadband is driving network and business model transformation. Mobile data traffic is growing exponentially, but mobile broadband revenue is not growing to the same proportions. Many mobile network operators are becoming victims of their own success. I recently met with a leading operator in EMEA, and they shared with me that 95% of their capital expenses are invested in data--though it only generates only 5% of their profits.

This scenario requires operators to re-think their business models and network strategies.

Can a "hook" monetize network intelligence?

Tue, 24 Jan 2012 10:38:00 -0500

Mobile Internet users have different priorities and expectations for their networks. Teenage users may want social networking, texting and an instant connection. For business users, the priorities are email and a high-quality, reliable network.

Yet, as operators attempt to meet the needs of their customers, they are struggling to further their own profitability. The price elasticity for mobile services is extremely low--one operator can’t charge significantly more for the same service than another. So, network optimization and cost reduction are a critical component of an operator’s strategy. But that’s not enough.
