An apparatus () and method () for receiving a communications signal. A spread spectrum signal demodulator () is adapted to demodulate a packet header () of a data packet () that is communicated by a wireless communications signal. The packet header () is modulated with a spread spectrum technique and the spread spectrum signal demodulator () produces a packet header detection signal () representing a successful detection of a predefined packet header value. A non-spread spectrum signal demodulator () is communicatively coupled to the spread spectrum signal demodulator () and demodulates, in response to the packet header detection signal (), a non-spread spectrum modulated data payload within the data packet. A data output select () produces demodulated data produced by either one or both the spread spectrum signal demodulator () and the non-spread spectrum signal demodulator ().

A multi-mode transmitter () is adapted to modulate a data packet () communicated by a wireless communications signal. The data packet includes a packet header comprising a preamble () and a start of frame delimiter (), and a data payload comprising a payload data length portion () and a payload portion (). The packet header is modulated with a spread spectrum technique. When transmitting a data payload in one mode, the data payload is also modulated with the spread spectrum technique. When transmitting a data payload in another mode, the data payload is modulated with a non-spread spectrum technique.
