The barrier of 1 Gbit/s will be reached in 2018 by power users. DSL will be too slow for most users in relatively short time. DOCSIS 3.1 provides a growth path for cable that will allow it to compete for at least another few years. Effective throughput/capacity are however still highly dependent on the amount of investment by the operator.
Invited to speak at the bi-yearly ‘AT Café’ at the Dutch Radiocommunications Agency (AT) in Groningen and Amersfoort, to speak about 5G, IoT and the role of the regulator. Read more here.
On June 15, the Dutch Radiocommunications Agency has published their annual ‘State of the Ether’ report for 2015. The report provides an overview of the Dutch wireless spectrum usage and trends. Especially interesting is this page, which provides insight in the total capacity of Dutch mobile networks. These pictures are …
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 …
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 …
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 …
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 …
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 …
Kennisnet, the organisation that facilitates the use of ICT in the Dutch educational system, today published a guide that helps schools in the choice of external (internet) connectivity. Given a number of students and a level of simultaneous use, the guide provides minimum bandwidth requirements for today and in the future. Secondly, it …
In April 2016, I gave a presentation at Eindhoven University of Technology on quantitative geographical analysis in the domain of telecommunications. Download slides: Quantitative geo-analysis in telecommunications
