Traditionally in data exchange among devices, all devices equally share the energy burden incurred in signal transmission and reception, limiting you to the device with the smallest energy capacity. This invention was developed to address this asymmetric available energy mobile devices encounter, allowing one to shift the energy burden to the highest capacity device, allowing more data to be exchanged before recharging. Braidio is able to dynamically switch the transmission carrier between transmitter and receiver and increases the number of bit exchanges between a transmitter and receiver by more than two orders of magnitude over Bluetooth, particularly in highly asymmetric scenarios. Braidio 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.
This invention can extend battery life of the smaller device hundreds of times in some cases. 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.
