A method, comprising: generating, at a first communication device, a first portion of a wakeup packet, wherein the first portion of the wakeup packet corresponds to a legacy physical layer protocol, PHY, preamble corresponding to a communication protocol, wherein the first portion of the wakeup packet includes a first orthogonal frequency division multiplexing, OFDM, symbol that spans a first bandwidth and is modulated according to a modulation scheme; scrambling, at the first communication device, a plurality of information bits to generate scrambled information bits to be included in a second OFDM symbol that spans the first bandwidth, the plurality of information bits intended for one or more second communication devices; generating, at the first communication device, the second OFDM symbol to include the scrambled information bits, wherein the second OFDM symbol spans the first bandwidth and is modulated according to the modulation scheme; generating, at the first communication device, a second portion (624, 628) of the wakeup packet, wherein the second portion of the wakeup packet corresponds to a second bandwidth that is less than the first bandwidth, wherein the second portion of the wakeup packet is configured to prompt one or more wakeup radios at the one or more respective second communication devices to prompt one or more respective network interfaces to transition from a low power state to an active state, and wherein the second portion of the wakeup packet does not conform to the communication protocol; and transmitting, by the first communication device, the wakeup packet, including transmitting, in time, the second OFDM symbol between the first portion of the wakeup packet and the second portion of the wakeup packet, and wherein the modulation of the second OFDM symbol according to the modulation scheme signals to third communication devices operating according to the communication protocol that the wakeup packet does not conform to the communication protocol. generating, at a first communication device, a first portion of a wakeup packet, wherein the first portion of the wakeup packet corresponds to a legacy physical layer protocol, PHY, preamble corresponding to a communication protocol, wherein the first portion of the wakeup packet includes a first orthogonal frequency division multiplexing, OFDM, symbol that spans a first bandwidth and is modulated according to a modulation scheme; scrambling, at the first communication device, a plurality of information bits to generate scrambled information bits to be included in a second OFDM symbol that spans the first bandwidth, the plurality of information bits intended for one or more second communication devices; generating, at the first communication device, the second OFDM symbol to include the scrambled information bits, wherein the second OFDM symbol spans the first bandwidth and is modulated according to the modulation scheme; generating, at the first communication device, a second portion (624, 628) of the wakeup packet, wherein the second portion of the wakeup packet corresponds to a second bandwidth that is less than the first bandwidth, wherein the second portion of the wakeup packet is configured to prompt one or more wakeup radios at the one or more respective second communication devices to prompt one or more respective network interfaces to transition from a low power state to an active state, and wherein the second portion of the wakeup packet does not conform to the communication protocol; and transmitting, by the first communication device, the wakeup packet, including transmitting, in time, the second OFDM symbol between the first portion of the wakeup packet and the second portion of the wakeup packet, and wherein the modulation of the second OFDM symbol according to the modulation scheme signals to third communication devices operating according to the communication protocol that the wakeup packet does not conform to the communication protocol.
