Ooohhh! You know what, I learned something new today! Thank you so much for taking the time to explain it in a way that made sense to me.

…you don’t see the advantage in avoiding open heart surgery to replace an embedded medical device?

While I agree with you in principle, that’s a hard sell to somebody with an embedded 2G medical device.

You don’t want random companies making cell signal transceivers.

Setting “companies” aside, I don’t see why it couldn’t be some sort of DIY project. Like, a small computer with a both a 2G and 5G modem, a set of antennas for each, and some middleware…

In fact, there are some phones that support both networks… So why couldn’t a spare phone be used? They technically already have all the hardware to make it work.

It sounds like there’s a really big market opportunity for somebody to make a portable transceiver that converts 2G and 3G signals into 5G…
