Ride the Radio Waves

Motes are wireless, so the information is passed along through radio waves, a bit like a mobile phone. Each mote has its own antenna. It has to be clear of any obstacles so that the radio waves don't get blocked. For this reason, motes are usually placed up high. Using radio waves is a big advantage as it means we don't need miles of cables to connect all the motes together. Can you spot the mote in this picture?
