A wireless extension cord can beam to 300ft from a wall outlet to a satellite unit using microwaves in the 7.2GHz range - so it doesn't interfere with wireless networks and Bluetooth.
I don't think I need to get into how useful this could be - inside and out.
Warning: Even though these microwaves are about as harmful as the leakage from an ordinary microwave oven (not much), do not put computers, televisions, other sensitive electrical equipment, food, liquids, paper, glass, flammable substances, magnets, or living things in between the base and satellite units. Just in case.Editor Update: Yup, confirmed.. April Fool is great isn't it, especially when it is placed in a very reliable online shop, or not ;)
