A 4G technology like TD-LTE allows users to do more using faster smartphones. However, as happens in fairy tales, all good things have a caveat: Every time the user clicks on an app, the smartphone will send a signal to the base station. In fact, every time we use data services, each session requires a fair amount of signaling. If there were only one user in the world, this would not be a challenge. However, if several hundred individuals are using data services at the same time in close proximity to each other, you have something called interference. In such conditions the base station is having trouble interpreting the signals it receives – and the smartphone needs to resend the signal until the base station understands it. And the user? The user will either have a bad reception, or will not receive the requested data at all.

According to the latest Nokia Siemens Networks’ research, liaisons between operators and many of their customers are entering a critical stage. Importance of mobile broadband quality for customer retention has increased heavily year-on-year, but at the time satisfaction with it has been decreasing dramatically. Especially the most loved ones – the high value customers – are more dissatisfied with mobile broadband quality than ever and risk to take actions and quit their current relationship, looking for better service. It is high time for operators to spend more effort to keep their customer relationships fresh and exciting. As Amiram Mel, Head of Customer Experience Management at Nokia Siemens Networks says: “Listening, understanding and reacting lie at the heart of strong customer relationships.†Put a little love back into how people feel about their operator Our new CEM on..

Nokia Siemens Networks and Aalto University are organizing an active antenna design competition for students as part of World Design Capital Helsinki 2012. One of the key themes of the World Design Capital Helsinki 2012 is looking at how good design can improve peoples’ everyday lives. During the project, Nokia Siemens Networks and Aalto University will explore possibilities for new design in future mobile network antennas. Antennas are part of our urban environment and make it possible for people to use data and voice services with their mobile devices. Dynamic efficiency of antennas is increasingly important, in the context of explosive growth of mobile broadband. Demand for network capacity fluctuates due to the ebb and flow of people in a city. Network capacity – and thus antennas – needs to be where..

We have recently shared information about heavy network traffic load generated by Android phones. Looking at existing 3G smartphones that have been tested in our Nokia Siemens Networks Smart Labs using OTT Voice over IP applications Nimbuzz, GoogleTalk and Skype, the issue seems to be more about different smartphone behavior. This includes the signaling load during a Skype voice call on Samsung´s Android phones compared to Nokia phones and iPhones. The Android phones generated 600% more signaling traffic during VoIP calls, which results in more network congestion caused by proprietary device-controlled Fast Dormancy. The difference is called 3GPP Release 8 - Network Controlled Fast Dormancy (NCFD). Release 8 requests that radio access technology (e.g. from Nokia Siemens Networks) needs to support NCFD to reduce signaling so that smartphones can benefit with longer battery life time. Calculated..

American football's biggest game this weekend may have lasted just a few hours, but telecom networks were gearing up a year ahead to meet peak loads, with network upgrades, additional capacity and more. Operators face the same challenges of variable loads, whether it is an event like Mobile World Congress or the daily ebb and flow of people across a city. And as our Mobile Broadband 2020 infographic suggests, the challenges will only grow exponentially in the years ahead. Our Liquid City demo explains the liquid approach to meeting the challenge using existing network capacity.
