why does bluetooth only cover short distances up to about 30 feet?
because of the arrangement of cable towers
because the technology is incredibly new, invented within the past two years
because that is how the king of denmark created it
because it relies on radio signals

Explanation:

Bluetooth uses low-power radio signals in the 2.4 GHz ISM band. Low power limits signal range to ~30 feet (class 2 devices) to save battery and reduce interference. Cable towers are for wired networks; Bluetooth is not new (invented 1994); the King of Denmark reference is a naming origin myth, not a functional reason.

Answer:

because it relies on radio signals
