We ask the experts: How can exceptional QoE be achieved in VoLTE networks?

By: Jean Jones, Director, Wireless Marketing, Alcatel-Lucent

What does voice over LTE (VoLTE) offer your subscribers? Better voice quality, including HD voice. Rich communications with messaging and video. And whatever inventive applications you choose to introduce. In other words, VoLTE can provide a superior quality of experience (QoE) for subscribers and give you a competitive edge — particularly when your service operates at its best.

In my last blog[CCE1] , our experts explained why an end-to-end strategy is the key to maintaining peak VoLTE performance. Now we’ll look at how this strategy gets put into practice to optimize real-world service offerings. The information here is based on interviews with Luis Venerio who works with our VoLTE Readiness Services team. And his observations come straight from his experience on VoLTE deployments that serve millions of subscribers.

How signaling spikes affect networks: 3 real-world examples

By: Josee Loudiadis, Director of Network Intelligence, Alcatel-Lucent

Data and signaling growth are usually good news for network operators, since growth often translates into higher revenues. But when growth is averaged over a month or quarter, the daily highs and lows of network activity are smoothed out. And signaling spikes remain hidden within the averages. These spikes can overwhelm available signaling capacity, which impairs the customer experience, as well as the operator’s reputation.

What happens when a spike occurs? Typically, a CPU Overload alarm appears on various mobile nodes. And the Network Operations Center (NOC) immediately starts praying that the burst is short-lived and doesn’t go over maximum peak-rate capacity. Because when that happens, all consumers are denied service access. Then, the process of identifying the source of the problem begins. This can be arduous, because it often involves applications completely out of NOC control. And the issue can’t be resolved easily without solid network analytics that enables engagement with application and device developers.

That’s the reason signaling information is a crucial part of the Alcatel-Lucent Mobile Apps Rankings report and why LTE World 2014 devotes an entire pre-conference day to the topic. It’s also why this blog offers a closer look at how some real-world disruptive signaling spikes got started — and were finally resolved.

Switchvox 5.5 - Sneak Peek!

October 26, 2011

I caught the tail half of Digium's Tristan Barnum's AstriCon session. Tristan Barnum is the Director of Product Marketing for Switchvox at Digium. In her AstriCon session, Tristan stressed how she never ever tells what Switchvox is up to and certainly not what features to expect.

"Switchvox 5.5 is due out the first quarter of the year [2012].

LOREX Live Connect Wireless Skype Home Surveillance Review

October 25, 2011

The LOREX Technology Live Connect LW2031 Series is a cool Skype-powered home surveillance system sporting night vision (via IR LEDs) and full color H.264 video. It can be used both for home surveillance, but also as a baby monitor due to its night vision and its portable handheld monitor sporting a color 2.4" LCD. It seemed like an interesting Skype product so I had LOREX send me a LW2031 to review.



Installation
Installing this was pretty straightforward. Two of the three devices - camera & handheld monitor use mini-USB power adapters, which are included.

Quantum Levitation = Back to the Future Hoverboard?

October 18, 2011

Tel-Aviv University recently demonstrated quantum superconductors locked in a magnetic field causing a superconducting disc to be suspended above or below a set of permanent magnets - seemingly defying the laws of gravity. But unlike other magnet tricks, you can move the object and it stays in the new position. Or you can spin it and it seems to spin endlessly due to near zero friction.

The magnetic field is locked inside the superconductor - a phenomenon called 'Quantum Trapping'.
