As I’ve already noticed last year, there is quite a bit of packet loss over Starlink connections that has a significant impact on TCP performance. Also, I was wondering if and how much packet loss occurs in cellular networks during a handover. Recently, I picked up this topic again and was looking for a way … Continue reading Analyzing Packet Loss in Starlink
Every now and then I am at places at the fringe of the observable Internet where I only have slow, weak and unreliable connectivity. Typically, though, there are several of such networks to chose from, for example because network operators share towers. Wouldn’t it be great if one could combine those networks to get some … Continue reading Multi-Path Backhaul with Speedify – Part 1 of 2
In the previous post on the topic, I’ve been looking at how 3GPP has studied and then extended the LTE and 5G NR air interface so it can be used over a satellite link. For transmitting data to and from smartphones with omnidirectional antennas over satellites, 3GPP has extended the LTE Narrowband Internet of Things … Continue reading NTN Part 2 – NB-IoT over Satellite
In recent months, satellite services for smartphones have been hyped a lot. While surprising for many, including me, this didn’t come out of nowhere, and a lot of companies have worked on this topic for quite some time. 3GPP has also picked up the topic a few years ago with study items in 3GPP Release … Continue reading NTN Part 1 – 3GPP Rel. 17 – Non-Terrestrial Networks
It’s the time of the year again to spend a few minutes looking back to the major things in tech that happened for me this year and ended up on this blog. So without further ado, let’s jump right in and have a look at the things that moved me in 2025.
I recently flew to Iceland with Iceland air, and as it was a 3 hour flight from Frankfurt, I was happy to try the on-board Internet to stay connected. For 12 euros a flight, it was perhaps not cheap, but compared to the price of the ticket, it’s almost negligible. As large parts of the … Continue reading In-Flight to Iceland with Viasat
It’s the time of the year again to reflect on what has happened in the last 12 months and looking back, I’m happy to say that it has been an eventful year again. So let’s jump right into it.
It’s the time of the year again to reflect on what has happened in the last 12 months. It’s been quite a ride again, with many things happening, and also some things not happening. So if you are interested, come with me on a trip through my year in tech 2023.
One thing I was pretty certain about when I bought my Starlink terminal was that I would put it in places where power would not be readily available. Maybe only a few meters away, but still, out of reach. As the Starlink router requires a 110/230V power source, a USB battery pack doesn’t work. And … Continue reading Power for Dishy: The Anker 521 Powerhouse
Another crazy year, both good and bad in so many ways, is coming to an end, so here I go with time honored tradition of looking back to what moved me this year in tech! In The Wireless Domain Obviously, there’s been a lot going on in the wireless domain again. While some parts of … Continue reading Things That Moved Me in 2022
