Braidio

About

Technology This invention was developed to address the asymmetric available energy mobile devices encounter.  Braidio (a braid of radios) can operate across active and passive modes, and addresses the increasing asymmetry in energy availability as devices become smaller. Braidio is able to dynamically switch the transmission carrier between transmitter and receiver and increases the number of bits exchanges between a transmitter and receiver by more than two orders of magnitude over Bluetooth, particularly in highly asymmetric scenarios. Braido operates like a standard Bluetooth radio when a device has sufficient energy, but operates like RFID when energy is low, off-loading energy use to a device with a larger battery when needed. Braidio capability can enable power-proportional wireless communication wherein two devices with different battery capacities can multiples between the different carrier modes, making it practical for a range of mobile devices from laptop to smart watch.
