Range extension techniques for a wireless local area network

An apparatus comprising:

• means for generating a first sequence of bits;
• means for spreading each of the bits in the first sequence with a second sequence of more than 11 chips to generate a range extension preamble, wherein the second sequence comprises a third sequence of at least two values, and wherein each of the at least two values in the third sequence is spread with a Barker sequence of at least 11 chips;
• and
• means for appending the preamble to a packet to be transmitted in a wireless local area network (WLAN).

A method comprising:

• generating a first sequence of bits;
• spreading each of the bits in the first sequence with a second sequence of more than 11 chips to generate a range extension preamble, wherein the second sequence comprises a third sequence of at least two values, and wherein each of the at least two values in the third sequence is spread with a Barker sequence of at least 11 chips;
• and
• appending the preamble to a packet to be transmitted in a wireless local area network (WLAN).

A non-transitory computer program product comprising code for causing at least one processor to:

• generate a first sequence of bits;
• spread each of the bits in the first sequence with a second sequence of more than 11 chips to generate a range extension preamble, wherein the second sequence comprises a third sequence of at least two values, and wherein each of the at least two values in the third sequence is spread with a Barker sequence of 11 chips;
• and
• append the preamble to a packet to be transmitted in a wireless local area network (WLAN).
