Abstract: In general, a system is described that includes two computing devices, a first which is configured to operate using a first wireless protocol and a second which is configured to operate using a second wireless protocol different than the first wireless protocol. The first computing device may determine a symbol to be sent to the second computing device. For each bit included in a payload of a data packet, the first computing device may set a value of the respective bit such that the symbol, when the data packet is translated into at least one signal using the first wireless protocol, is readable using the second wireless protocol. The first computing device generates the signal using the first wireless protocol, and outputs, via the first wireless protocol, the at least one signal. The second computing device may receive the at least one signal and demodulate the payload.
