Comment on Why most countries are struggling to shut down 2G.

  Not just old people. I had a heart monitor a couple years ago that’s only made for 2G.

  Alright maybe I’m getting old but that’s not the point.

  When I was visiting the Caribbean they also had a lot of 2G infrastructure still operating.

    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…

      Really really difficult to do that at scale. You don’t want random companies making cell signal transceivers.

      You’d be better off just replacing the 2g transceivers entirely.

        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.

      I’m not sure there would be an advantage. The signals are very different. That might be approximately equal to building a new one.

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