1. A method for transmitting a wireless packet, the method comprising:
- generating, using control circuitry, a training field sequence;
generating, using the control circuitry, a preamble for a packet, wherein the preamble comprises a first training field symbol, wherein the first training field symbol comprises the training field sequence, wherein respective portions of the training field sequence are located at respective guard tone locations at both ends of the first training field symbol; and
transmitting, using transmit circuitry, the preamble, wherein the transmitting comprises transmitting tones of the first training field symbol with the same frequency domain power per tone as tones of a second training field symbol.

Abstract
A method for transmitting an 802.11ah packet is provided. A training field sequence is generated using control circuitry. A preamble for a packet is generated using the control circuitry. The preamble includes a training field symbol which includes the training field sequence. A portion of the training field sequence is within a plurality of guard tones of the training field symbol. The preamble is transmitted using transmit circuitry.
