How 4×4 MIMO can boost your mobile network

The inexorable demand for more mobile data volume requires ever-higher capacities in radio mobile networks. Network densification and the introduction of new frequencies could be solutions, but both are time-consuming and cost intensive. The implementation of higher-order MIMO features into existing radio networks, however, will boost peak data rates throughout the network and deliver an additional capacity gain. 4×4 MIMO…

5G: initial 5GTF coverage measurements

The US operator Verizon Wireless targets fixed wireless access (FWA) in the 28 GHz frequency band. With partners, they created a pre-5G specification called 5G Technical Forum (5GTF). The business case depends on the number of households that can be connected to a certain number of base stations and still provide a suitably high data throughput. For the required signal…

5G: the role of mobile network testing on the path to 5G (part 1)

Everyone is talking about 5G. Long before commercial 5G services are even available, a myriad of articles, reports, presentations and speeches have been made public – creating a big buzz and high expectations in the new standard. What’s the role of mobile network testing on the path to 5G? How can scanner measurements help operators pave the way to the…

Combined engineering and benchmarking measurements add value

Different mobile network measurement tools target different measurement scenarios. One might be the preferred choice for collecting mass data for benchmarking; another might offer extensive possibilities for engineering and troubleshooting. Do we always know how the collected measurement data is being evaluated when we are performing the actual measurement? Most probably not. But wouldn’t it be great if we could…

Measuring QoE of mobile data apps for network optimization (part 3 of 3)

How can mobile app testing support network optimization? In previous posts, we explained how you could assess the QoE of data applications on smartphones by measuring the success rate and duration of a series of actions. Based on large-scale real field measurement data, we showed how the duration saturates at higher available network speeds and examined the causes of this…

Measuring QoE of mobile data applications: behind the scenes (part 2 of 3)

In the previous post, we explained how to measure QoE of mobile data applications on smartphones by means of success rate and the duration of a series of actions. Based on large-scale real field data, we showed how the duration saturates at higher available network speeds. But where does saturation come from? And what is going on in the background,…

NB-IoT: how to test quality of service in NB-IoT networks (part 4 of 6)

NB-IoT networks are designed for machine-to-machine communication, which generally requires low data rates. When building NB-IoT networks, it is essential to test the performance of new implementations to ensure that the required network quality is available. Tests to measure quality of service (QoS) in NB-IoT networks are typically performed with NB-IoT modules that are controlled by software. Our measurement software…

HetNets/Small cells: verifying indoor deployments (part 4 of 4)

HetNets and small cell indoor deployments are an effective means to deal with the exponentially increasing data consumption in mobile networks. After the careful planning and actual installation of a new small cell network, it’s time to verify the commissioned indoor deployments and ensure quality of experience (QoE). Both are best achieved with a commercially available smartphone, designed for reliable…
