Happy New Year 2020 to all of you! It’s the time of the year again when it makes sense to take a look back at the last 12 months of 2019 to see which tech things and events ‘have moved me’ during the course of the year. Like in the previous years, it is once … Continue reading Things That Moved Me in 2019
When I want to test the data rates of networks I connect my PC to, I usually use wget to run a large file download from a public server to /dev/null. In the uplink I use an FTP server on the other side to push a file with randomized content. But actually, that is rather … Continue reading Let’s Have Some IPerf Fun With 10 TB of Included Server Traffic
After upgrading to VDSL vectoring with a 100 Mbit/s downlink and 40 Mbit/s uplink in Cologne recently, I soon figured out what to do with the additional uplink speed: Advanced synchronization with my network behind a fiber line in Paris. Equally soon I noticed that no longer is my access link the bottleneck but rather … Continue reading Backbone Bottlenecks
A few days ago, there’s been a great talk about G.Fast at the Local Chaos Computer Club chapter (C4, Cologne) by Stefan Förster of NetCologne. Here’s a link to the video of the talk (in German). I was particularly interested, because NetCologne recently announced that they have finished their G.fast trial (using the existing telephony … Continue reading VDSL and G.Fast Coexistence
After the line of my neighbor has been switched to a different port in the street side DSLAM and mine followed a couple of days later, I finally have a stable DSL line again. There are many factors influencing the maximum uplink and downlink speed that can be achieved over a copper wire and since … Continue reading DSL, Vectoring and Line Length
I'm a bit nostalgic today because my ISDN telephony days are over. A few days ago, I was “upgraded” to an all-IP line at home because my network operator of choice wants to decommission its ISDN public telephone network, offer VDSL vectoring (instead of fiber connectivity, yeah, right…) and migrate everyone to Voice Over IP. … Continue reading VDSL Speed Upgrade and All-IP – My ISDN Days Are Over
It's a bit ironic but my uplink speed in LTE is three times higher when I'm sitting in a train comunting to work and being connected over LTE than what it would be when sitting at my desk at home and being connected over a 25 MBit/s down + 5 Mbit/s uplink VDSL line. I … Continue reading My Uploads Are Three Times Faster On LTE Than With VDSL At Home
I've been in Austria again this summer for a couple of weeks and thanks to Drei.at's unlimited data bundle for 18 Euros a month on a prepaid SIM I didn't have to artificially limit my data use. Last year, I ran through 16 GB of data during my 3 weeks stay and slightly topped it … Continue reading This Year’s Holiday Network Setup And Data Use In Austria – 18 GB
Another year is drawing to a close and as in the years before I wondered what has happened during the year. And as always I was quite surprised when I went through my blog entries of the past 12 months about the amount. So here are my personal technology highlights of 2014: LTE and Affordable … Continue reading My Personal Technology Highlights in 2014
I've been running an OpenVPN server at home to protect my data traffic for quite some years now, first on an WRT54 Wi-Fi Router and later on a Raspberry Pi thanks to a great article over on ReadWrite. The solution I had so far has been limited to a maximum throughput of 5 Mbit/s as … Continue reading How Fast Is An OpenVPN Server on A Raspberry Pi And A Banana Pi?
