GSM 450: Stating the obvious, wrongly
Ryan Block of Engadget writes:
As if what we really needed to add to our quad-band dual-mode 3G DMB phone’s repertoire was support for yet another swath of spectrum, but it looks like we might have to get it anyway—at least if we’re interested in taking a trip to developing nations in the near future. Less because things are gettin’ crowded up in the 800 / 900 / 1900 / 1900 / 2100MHz zones than because the lower on the spectrum you get the more powerful you can make your signal with less worry of noise and interference.Ick. The last part appears completely made up because it's not mentioned in the linked article. The 450MHz band provides better coverage because lower frequency signals are attenuated less by the Earth's atmosphere, and therefore you get longer range from the same transmitter power. That might be what Block was trying to say, but it looks to me like a misguided attempt to add some "tech" detail to an admittedly spartan story.
