Mobile phone wireless tech

Was just thinking randomly about how many wireless transceivers my phone has.. there’s a lot

  • Cellular (several bands)
  • Wifi (2.4 and 5Ghz)
  • Bluetooth, including Bluetooth LE
  • NFC
  • GPS receiver
  • Ant+ receiver

That’s 6 RF radios, as well as infrared…

Also I might get a wireless changing thingo for inductive charging.. That’s another!

Although the only point of interest as far as health would be the radiated power.. people seem to get all hung-up about wifi, when cellular is a much more powerful signal.. A cellular signal has to travel all the way to the nearest phone tower, where as wifi might have 30-50m range tops.. From memory a cell radio in a phone may have 1-4W of power, where as wifi is maybe up to 200mW tops… 200 would be surprising. so likely more than an order of magnitude difference between wifi and cellular. People don’t seem to realise that. Although that being said, wifi is possibly used more frequently. I’m thinking I should disable cellular while I’m sleeping.

Bonus point coffee

Usually I put cacao and maca on my oats, and sometimes coconut oil but they’ve just been sitting there since this be diet. I added them to a long black and yup it’s pretty good. Basically it’s

  • Freshly ground locally roasted beans through an espresso machine – this seems to taste better than my drip coffee.
  • Hot water.
  • .3 teaspoon Cacao
  • .3 teaspoon Maca
  • 1 teaspoon coconut oil
  • .3 teaspoon cinnamon
    When I added the cinnamon it was pretty strong, but cinnamon is supposed to be good for you so whatever.
