Wireless communication device and method that utilize spread spectrum modulation to hide vendor information

A wireless communication device, comprising:

• a processor circuit;
• and
• a transceiver circuit configured to determine whether a string to be transmitted in a physical layer is a specific data string of a packet, modulate the string according to a spread spectrum sequence code corresponding to a first vendor when the string is the specific data string, and transmit the packet to an electronic device such that the electronic device determines whether the first vendor is a predetermined vendor,
• wherein if the electronic device determines that the first vendor is the predetermined vendor, the processor circuit is further configured to perform a specific communication mode of the predetermined vendor to connect to the electronic device when the electronic device determines that the first vendor is the predetermined vendor, if the electronic device determines that the first vendor is not the predetermined vendor, the processor circuit is further configured to perform a predetermined communication mode of a predetermined communication protocol to connect to the electronic device when the electronic device determines that the first vendor is not the predetermined vendor, and if the string to be transmitted in the physical layer is not the specific data string, the transceiver circuit is further configured to modulate the string to be transmitted in the physical layer according to a spread spectrum sequence code corresponding to the predetermined communication protocol when the string to be transmitted in the physical layer is not the specific data string.

A wireless communication method, comprising:

• determining, by a first wireless communication device, whether a string to be
• transmitted in a physical layer is a specific data string of a packet, and modulating the string according to a spread spectrum sequence code corresponding to a vendor of the first wireless communication device when the string is the specific data string;
• transmitting, by the first wireless communication device, the packet to a second wireless communication device;
• demodulating, by the second wireless communication device, the packet according to a spread spectrum sequence code corresponding to a predetermined communication protocol to obtain the specific data string;
• determining, by the second wireless communication device, a first detection value according to the specific data string and the spread spectrum sequence code corresponding to the predetermined communication protocol and a second detection value according to the specific data string and a spread spectrum sequence code corresponding to a predetermined vendor, and determining, by the second wireless communication device, whether both of the vendor of the first wireless communication device and a vendor of the second wireless communication device are the predetermined vendor;
• if both of the vendor of the first wireless communication device and the vendor of the second wireless communication device are the predetermined vendor, performing, by the second wireless communication device, a specific communication mode of the predetermined vendor to connect to the first wireless communication device when both of the vendor of the first wireless communication device and the vendor of the second wireless communication device are the predetermined vendor;
• and
• if at least one of the vendor of the first wireless communication device and the vendor of the second wireless communication device is not the predetermined vendor, performing, by the second wireless communication device, a predetermined communication mode of the predetermined communication protocol to connect to the first wireless communication device when at least one of the vendor of the first wireless communication device and the vendor of the second wireless communication device is not the predetermined vendor.
