What will be the demand for internet speed in 2022?

Together with Eindhoven University of Technology (TU/e), Dialogic performed a study on how residential upload and download speed demand will have developed by 2022 (I was the project lead for this study). The research focuses on consumers in the Netherlands and other West European countries with highly developed broadband markets. Thestudy …

Will long-range wireless IoT in unlicensed bands cause issues?

Long-range, large scale deployments of IoT networks have high impact on the wireless spectrum. The main technologies for LPWA (low-power, wide area) IoT in licensed spectrum are LTE-M1 (LTE Cat MTC), LTE-M2 (NB-IoT) and (future) 5G IoT. In unlicensed spectrum, LoRaWAN (based on spread spectrum) and SIGFOX (ultra narrowband) are the most …

Things I learned while programming asynchronous, concurrent code in Swift

Having written about 80.000 lines of Swift code for Warp, I have learned a thing or two about the best way to deal with concurrency in Swift. You must not make assumptions about how callback blocks are called. Usually you want a callback function to do some work in a certain queue. Although you can design …

Will software defined networking radically change the Dutch telecommunications ecosystem?

Network virtualisation stimulates innovation in telecommunications by enabling diverse network architectures to cohabitate on a shared physical infrastructure. To make this possible, network elements need to be ‘programmable’ – software-defined networking (SDN) makes the control plane programmable, while network function virtualization (NFV) does the same for the data plane. By …

Can you use big data to measure music experience in a smart city? 

In this study, Dialogic investigated what data sources could be used to measure music experience in the municipality of Eindhoven, the Netherlands. We created a list of 50 data sources with potentially interesting data. Each data source was evaluated against 11 criteria for usefulness, such as complexity, accessibility, restrictions, security and availability. On the …

DHToT: storing IoT sensor data in the BitTorrent peer-to-peer network

The Internet of Things promises to connect virtually all devices and make sensor data ubiquitously available. Instead of storing all this data in a central location, you can use a peer-to-peer network to store sensor data. Using a peer-to-peer network has several advantages. First of all, the infrastructure is ‘free’ (although in …
