NB-IoT: how to find NB-IoT carriers in the spectrum (part 6)

Identifying NB-IoT carriers with a pure RF power scan is very difficult and sometimes impossible. After describing the benefits of NB-IoT MIB/SIB demodulation in the previous NB-IoT post, this post discusses the challenges in identifying NB-IoT carriers in the spectrum and offers solutions. The extended Automatic Channel Detection (ACD) feature finds and identifies NB-IoT carriers automatically and display the findings…

NB-IoT network insights through MIB/SIB demodulation (part 5)

Our scanner-based solution to measure coverage in NB-IoT networks pioneered NB-IoT field measurements in 2017. Since then, thousands of kilometers have been driven and walked in order to collect and analyze data from all available operators and cells in an NB-IoT network. Numerous NB-IoT field engineers shared their experiences, providing us with valuable feedback. This post summarizes our customers’ latest…

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

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…

What is the market for voice telephony in 2017?

In competition with messaging services and Facebook and Instagram timelines, is voice telephony at all relevant in 2017 and beyond? We believe: yes, absolutely! Telephony is still the most direct and most efficient way of telecommunication. Apart from being an auditory interaction, voice still transports much more emotion – and opportunity for clarification – than any emoticon ever could. Or,…

HetNets/Small cells: reliable small cell planning (part 2 of 4)

Reliable planning of small cells is essential for important and critical deployments. Consider hospitals, manufacturing facilities or VIP (CxO) office floors and meeting rooms (the list of examples is endless). Successful and cost-effective planning, and with it small cell deployments, require planning tools that ensure highest reliability and accuracy. This, however, is not always the case as floor plans might…
