Claim:
1. A first network device comprising: a physical layer module; and a medium access control module configured to (i) generate a first capabilities element, and (ii) in a sub-1 GHz band, transmit the first capabilities element to a second network device, wherein the first capabilities element includes (i) a multi-bit field indicating whether transmission of a packet with a traveling pilot is supported by the first network device, or (ii) a field indicating whether transmission of a single spatial stream over a 1 MHz channel from the first network device to the second network device is supported by the first network device, the first capabilities element further includes a first field including modulation and coding fields, wherein the modulation and coding fields include respective modulation and coding sets, and wherein each of the modulation and coding sets indicates a modulation type and a code rate, and a second field indicating, based on a number of spatial streams indicated by the first field, one of the modulation and coding sets are applicable for transmission of the packet, the medium access control module is configured to, subsequent to transmitting the first capabilities element to the second network device, forward data to the physical layer module, and the physical layer module is configured to (i) generate the packet to include the data, wherein the packet includes the traveling pilot if the first capabilities element indicates transmission of the packet with the traveling pilot is supported by the first network device, and (ii) according to the first capabilities element, transmit the packet to the second network device via one or more spatial streams, and wherein the one or more spatial streams includes the single spatial stream.
