Inspiration

Watched the media coverage of the Artemis re-entry and splashdown this evening. Hoped I’d hear the sonic boom, but I was too far away. The splashdown point was probably 20-30 miles south of San Diego, and our place is another 50-60 miles north of downtown. So no boom.

It was really nice to hear news folks talking about how we can do great things when we work together and put our minds to it. We sure need some inspiration these days, and I can’t think of a better place for it to come from – science and space technology, trained military, technicians, and astronauts, all working together to accomplish complex/difficult things. I sure hope some of the MAGA types who applauded DOGE cuts to science are watching this and thinking…hmm, maybe this stuff is worthwhile. Because it is.

I have a huge regret watching all this, though the regret was no fault of mine. I wanted to be an AF pilot, actually got my orders to report to the AF Academy, but there was a catch. The AF said no, you can’t be a pilot, my eyes were too bad and they didn’t allow correction. 15-20 years later my eyes could have been (were, in fact) corrected, and during that period the AF reversed policy and allowed corrective lenses or surgery. So my timing was just bad. I also could have been on an astronaut track because of my intense science and science fiction interests. Just wasn’t meant to be.

Tech Week

It’s turning out to be a tech week. Spent some time today and yesterday unpacking and installing the new T-Mobile home Internet equipment. There have been a few surprises.

First and biggest surprise was that the T-Mobile devices aren’t just a gateway to their 5G services. I thought I would just fire up the gateway as a replacement for the Spectrum cable modem, then attach the gateway to my home wifi mesh (an Eero setup) via Ethernet. But nope, it was a little more complicated than that. The T-Mobile device is a hybrid, both a 5G gateway and a wifi router. It produces a brand new wifi network in your home. Hmmm.

Not a deal breaker. I unboxed everything, fired it up, got the documentation using the T-Mobile phone app. It took a couple of tries, but I got the gateway up and running. The new network and gateway produced 250+ Mbps download speeds and maybe 25 Mbps upload, with the gateway facing southwest through a window. Not bad. Certainly better than what I’ve been seeing with Spectrum.

Then I connected each of my devices – phone, iPad, and laptop – to the new wifi network. No problem. Next up, connecting Apple TV to the new network. That was the next problem/surprise. Apple TV simply would not recognize or connect to the T-Mobile wifi. Subsequent research leads me to believe that I may have to tune the T-Mobile device to prioritize 2.4 Ghz channels, as the Apple TV may not even recognize the higher (5 and 6 Ghz) channels that the gateway is presenting. Haven’t tried that yet, but I will. The fallback if this doesn’t work is that I keep both wifi networks operation – Eero and T-Mobile. Downside of that is a high potential for interference.

One more tweak I will likely try is an external antenna for the 5G gateway. The gateway is simply sitting inside against a west-facing window. I’m surrounded by T-Mobile cell towers on the east and west sides, but all of them are at 2-3 miles away. The eastern towers (4000ish meters away, or 2.5 miles) are blocked by some high hills, but I may have line of sight to the western towers at a greater distance of 5500 meters, or 3.5 miles. Both cases are at the extreme limit of typical cellular coverage, and that’s in clear weather. In rainy/stormy weather, our received signal will be weaker. That’s where the external antenna comes in. It can give 2-5x the signal strength, a factor I’m likely to need. But I want to prove that the system will work for me in good weather, all devices, reliably, before I invest more with an antenna.

Bottom line, so far so good with the Spectrum alternative. A bit more complicated than I would have guessed, but no show stoppers.
