Next month at the gargantuan Electronica show in Munich, Germany—where everything from light rail cars to fiber optic modules is shown in miles of exhibition space every fall—the Berlin company Nanotron Technologies will unveil the first transceiver silicon based on its multidimensional multiple access (MDMA) technology.

What’s garnering gasps in the halls of communications engineering are the range and data rates—over 60 meters and more than 2Mbit/sec.—coupled with power consumption on the order of a keychain RFID tag. But the smile that follows those gasps comes from the chirping.

“The essence of Nanotron’s technology is that they use the chirp technology,” says Heinz Arnold, a company spokesman. “It’s based on the principle in nature. It’s the way dolphins and bats communicate. By chirping, signals or symbols are coded in a very, very effective way because the energy distribution is very constant over time. This is exactly what you want over time, that you are not allowed to go over a certain low level of energy,” Arnold says.
