On-Board Internet over the US with Delta

In the previous post I had a look at Delta Airlines’ on-board Internet connectivity over the Atlantic. On this flight, the company used Intelsat for connectivity and I assumed that the 30 day pass I bought would also give me connectivity during my continental flights with Delta. That was not the case however, and I soon found out the reason for this: Over the US, Delta uses a different system, provided by Viasat. So how did the Viasat system perform in the busy US airspace? The screenshot on the left gives a first indication.

On-Board Internet over the Atlantic with Delta

When I was recently in North America, I didn’t only have a look at the terrestrial networks there, but I was also looking forward to test Delta Airline’s on-board Internet connectivity over the Atlantic. In the past, I had mixed experiences with on-board Internet, and I had the impression that before Covid, on-board Internet was slowing down over the years. So how would connectivity work this time? The screenshot on the left already gives a first indication.

‘Allow 2G’ Switch in Android – How About Roaming?

As I tend to be a bit on the security conscious side of the discussion, I like the 2G-Allow switch on my Pixel 6 with LineageOS. By disabling 2G, I’m not prone to fallback attacks by network jamming and my device recovers more quickly from a loss of LTE coverage. For most of my daily usage scenario, returning to LTE more quickly is a significant benefit. But there is one catch one has to be aware of: Roaming!

Roaming Report – Part 10 – LTE and the Partial Lack of 5G Roaming in Canada

After having had a closer look at the LTE and 5G bands used in the US in previous posts, I traveled on to Canada and obviously also took the time to have a look at how my devices would work in this country. And once again, there were a number of interesting surprises, at least from a European point of view.

The Story of the Slow Mouse Button

Computer mice can be difficult. Some time ago I wrote about my notebook occasionally behaving strangely, which drove me crazy. I suspected all sorts of issues until I finally realized that the second Bluetooth mouse in my backpack was responsible for the erratic behavior. Now I have another mouse story that was equally baffling: An occasionally slow right mouse button.

The Android “Lockdown” Button

I’m not really a friend of biometric unlocking of my mobile devices for security reasons. But, I have to admit, I use the fingerprint reader on some of my devices anyway, it is just too convenient. I know, it’s not consistent behavior. But a few days ago, I saw this post on Mastodon that made me aware of the ‘Lockdown’ button in the Android menu that appears when pressing to on/off button for a second. I’ve used this menu many times but I never noticed the ‘Lockdown’ button. So what does it do? When pressed, it disables the fingerprint reader until the PIN code for the device has been typed-in again. In practice, it’s easy and quick to get to the button in case of need, even while the phone is locked in the first place but could be unlocked with the fingerprint reader. Great, this significantly changes the security / convenience balancing act for me!

P.S.: Not all Android UI flavors do have the button, but it is present in stock Android (but perhaps needs to be activated in a menu) and LineageOS (active by default). Good enough for me.

Roaming Report – Part 9 – Frequency Bands used for LTE and 5G in the US – Operator 3

There are three nationwide LTE/5G networks in the US. As I could roam in all three of them when I was recently in the US, I also had a look at the bands that are requested by the third network to be reported by the UE. So here are the results:

Roaming Report – Part 8 – Frequency Bands used for LTE and 5G in the US – Operator 2

Yes, the post titles are getting a bit long these days. Sorry about that. In this part, let’s have a look which 4G LTE and 5G NR bands for 5G Non-Standalone (NSA, ENDC) another nationwide US network requests my mobile devices to report and how this differs from the network I had a look at in the previous post.

Roaming Report – Part 7 – Frequency Bands used for LTE and 5G in the US – Operator 1

As I live in Europe, I pretty much know the EU LTE and 5G frequency bands by heart. In North America, however, the frequency ranges and particularly the band numbers are significantly different, so I had a closer look which bands my devices were using while having been there, and which bands the networks asked my devices to report back in their band support list.

Roaming Report – Part 6 – 5G Roaming in the US fixes the lack of no LTE-CA on some Devices!

When I was last in the US back in 2019, I noticed that quite a number of the test smartphones (from the EU) I had with me would not do LTE Carrier Aggregation (CA). Even worse, my devices where often sent to a 5 or 10 MHz Carrier, so data transfer speeds were abysmally slow in the single digit Mbps range. Already back then, I found such a device behavior pretty strange but hoped that time would fix this. Fast forward to 2024 and my recent visit to the US, where I could have another look:
