The MAC module, in a sub-1 GHz band, transmits the capabilities element to a second network device. The capabilities element includes: a multi-bit field indicating whether transmission of a packet with a traveling pilot is supported by the first network device; or a field indicating whether transmission of a spatial stream over a 1 MHz channel to the second network device is supported by the first network device. The MAC module, subsequent transmitting the capabilities element, forwards data to the PHY module. The PHY module: generates the packet to include the data, where the packet includes the traveling pilot if the capabilities element indicates transmission of the packet with the traveling pilot is supported; and according to the capabilities element, transmits the packet to the second network device via the spatial stream."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for transmitting and receiving a packet with a traveling pilot in sub-1 GHz band via one or more space time streams based on capabilities information","description":"A first network device including a physical layer (PHY) module and a medium access control (MAC) module.
