Also, the device transmits a frame including the legacy signal field and the HE signal field. At this time, a protection range of a symbol included in at least one of the legacy signal field and the HE signal field is set to be longer than 0.8 μs. So, the frame transmitting method can be used even in an outdoor environment. |
