Method and device for performing control in WiFi network

A method in a target device in a WiFi network, comprising

• determining whether a first management packet received from a control device includes a predetermined identifier;
• decoding the first management packet based on a predetermined decoding scheme if the first management packet received from the control device includes the predetermined identifier to obtain a control command;
• encoding a response to the control command in a second management packet;
• and
• transmitting the encoded second management packet to the control device;
• wherein the first management packet and the second management packets are processed using a custom encoding that is distinct from any standard WiFi management packet format used by a WiFi device.

A WiFi capable control device, comprising

• a first encoder configured to encode a control command in a first management packet, wherein the encoding of the control command is identified by a predetermined identifier;
• a first transmitter configured to transmit the encoded first management packet to a plurality of target devices;
• and
• a first decoder configured to decode second management packets received from at least one of the plurality of target devices, wherein the second management packets include dedicatedly encoded response in response to the control command;
• wherein the first management packet and the second management packets are processed using a custom encoding that is distinct from any standard WiFi management packet format used by a WiFi device.

A target device in a WiFi network, comprising

• a decision unit, configured to determining whether a first management packet received from a control device includes a predetermined identifier;
• a second decoder configured to decode the first management packet based on a predetermined decoding scheme if the first management packet received from the control device includes the predetermined identifier to obtain a control command;
• a second encoder configured to encode a response to the control command in a second management packet;
• and
• a second transmitter configured to transmit the encoded second management packet to the control device;
• wherein the first management packet and the second management packets are processed using a custom encoding that is distinct from any standard WiFi management packet format used by a WiFi device.
