White Paper: An Introduction to Carrier Aggregation Testing
Today’s mobile data services explosion imposes challenges on operators to provide high quality services for mobile applications in a cost effective manner. To support operators, the ITU initiated a global standard initiative for IMT Advanced systems which are required to meet enhanced user and service demands with peak data rate targets of 100 Mb/sec for high mobility and 1 Gb/sec for low mobility. In addition, IMT-A systems have to have key features such as functional commonality, intersystem operability, global roaming and user friendly applications.
White Paper: An Introduction to Testing LTE Broadcast Services
Mobile TV has become a reality with the introduction of smartphones. Multimedia broadcast/multicast (MBMS) based services covering the terminal, the radio and the core network as well as user aspects have been introduced by 3GPP Release 6. This release supports point-to multipoint data transmissions from a single source to multiple recipients as a means of providing a more bandwidth-efficient delivery of commonly requested data services.
White Paper: A User’s Perspective on Voice over WiFi Calling
Although still broadly available across the world, the traditional, well established, circuit switch (CS) mobile voice service with its well-known ability to provide subscribers high Quality of Experience (QoE) since the introduction of 2G services, is clearly fading. The evolution to 3.5G (HSPA+) already unleashed the technical means for Voice over Internet Protocol (VoIP) based solutions using mobility, such as the more or less free over-the-top (OTT) voice services like Skype and Viber. Lately, by the means of more widely spread and more mature LTE networks, VoIP solutions have become higher quality, and, more importantly, have allowed leading LTE carriers to deploy Voice over LTE (VoLTE) as the voice service solution with guaranteed QoE.
White Paper: HetNets: Opportunities and Challenges
With the explosion of mobile data services expected, operators around the globe are seeking ways to expand capacity in their networks. This capacity need is driven by the deployment of smartphones that are data centric and based on new data services – mostly video – that are hungrily consuming bandwidth and capacity in the networks. The industry is predicting that growth in users of smart devices will increase four- to five-fold by the end of 2014, and that the resulting data traffic will grow 30 to 40 times in volume. Mobile video is predicted to be the major driver of traffic in the network with estimates forecasting that it will drive 70 to 75 percent of the mobile traffic growth over the next few years.
White Paper: Mobile Video Streaming Delivery Impacting QoE Testing
Bandwidth limitations, capacity concerns, the abundance of high definition video content, and advanced video capable smartphones are the main factors that can negatively affect subscribers’ satisfaction when using video streaming services.
White Paper: TEMS™ Capacity Manager: Cost-Efficient Mobile Network Dimensioning
In this white paper, we will show how TEMS Capacity Manager can analyse the complex data from mobile communications networks and present the results in a clear and concise form for the operator’s benefits. A network wide analysis increases the ability of the operator to target the areas of the network which most need the extra resources; reducing both the amount and delaying the timing of CAPEX upgrades. Individual element analyses ensure that each site can be tuned to its unique environment. TEMS Capacity Manager has already been installed by various clients and over a number of operational years has demonstrated real network operational efficiencies and significant CAPEX savings.
White Paper: The Role and Benefits of RF and Performance Modeling Tools in the HetNet Era
The growing and ever harder to reach demand from consumers for seamless mobile connectivity both indoors and outdoors is driving a proliferation in the types of Radio Access Network (RAN). Small cells, macrocells, Wi-Fi and DAS must all work together in the ‘heterogeneous’ network to deliver good experiences wherever consumers are – and for an ever-widening range of different service types and applications.
White Paper: Voice Service Over LTE Networks (VoLTE) and the Implications for Testing
The introduction of 3G networks and the ensuing evolution to 4G/LTE, combined with the exponential growth of smart devices, have changed the wireless ecosystem from every perspective: technical, business and the customer experience.
White Paper: A Call to Action for Improved RAN Management
Today almost all the mobile network operators (MNOs) plan their radio access network (RAN) expansions based on network triggers related to the percentage of utilization of a set of network element engineering KPIs. We will discuss how these network element KPIs do not accurately represent capacity, we will offer an alternative approach based on customer experience metrics, we will introduce the concept of “headroom” capacity, and describe how MNOs can better manage RAN expansions by relying on the headroom metric.
