How modernized GSM supports smartphones

Today, GSM enables voice calls around the globe. At the same time, the number of smartphones is rising rapidly, as is mobile data usage. Operators refarm GSM frequencies and maintain GSM services Smartphones need bandwidth, and bandwidth needs frequencies. Thus, operators are refarming part of the GSM frequencies to HSPA and LTE. A lean and … Continue reading

Cloud provides capacity in simple terms

 It is a tedious business to build enough coverage, data and signaling capacity without overdimensioning and thus overspending Voice calls, video streaming, internet browsing, smartphone app signaling, video calls all require a different combination of parameters for quality service. Voice patterns are continuous It takes two to make a phone call, and the data rate … Continue reading

Hot zones are areas where people use data services heavily. This can be any government campus or central business district, an airport, a shopping and office mall or a highly frequented pedestrian zone. Finding sites close to Hot Zones and achieving good indoor signal levels is difficult. Operators traditionally add capacity for hot zones by … Continue reading

Multiflow for HSPA and Coordinated Multipoint for LTE provide better bandwidth Today, my phone connects to one base station only So far, my phone uses the strongest signal from the surrounding base stations. Weaker signals from other base stations only interfere. I get a good signal when I am close to the base station, but … Continue reading

In most of my recent customer interactions, a key unanswered question is – how can I as a service provider distinguish my brand, and improve my financial performance today?

We all know that IP networks simplify network architecture, reduce costs, increase network performance and reliability, enhance network and subscriber manageability and enable the introduction of many new services and applications for operators. But migrating to an all IP network remains a challenge for them. The transformation is not straight forward as operators cannot just … Continue reading

4G broadband technologies such as LTE enable users to surf the Internet while accessing applications. All this happens at unprecedented speed, guaranteeing a great user experience. However, when you are sitting in a cabin at 9.000 feet on top of a glacier – as recently happened to me – it becomes clear that you can’t … Continue reading

While there are many exciting opportunities for operators in this new world of communications, unprecedented growth and unpredictability of demand threaten to strain network and business processes. Our research predicts that total mobile broadband traffic may increase up to a thousand-fold by 2020. Given this scenario, operators will have to make sure that their networks … Continue reading

Nokia Siemens Networks applauds the U.S. Congress for making the bold decision to free up much needed spectrum for mobile broadband through voluntary incentive auctions. By also setting aside spectrum and critical funding for a nationwide public safety mobile broadband network, Congress can be proud of a rare double achievement that will benefit consumers and … Continue reading

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 … Continue reading
