1. A method comprising:
- selecting, at a transmitter, tone scaling parameters for use in communicating a packet via a sub-one gigahertz wireless network operating at a particular bandwidth, wherein the tone scaling parameters are selected based at least in part on a frame format of the packet and the particular bandwidth, wherein the frame format includes a single user frame format or a multi user frame format;
generating the packet, wherein generating the packet comprises scaling fields of the packet in accordance with the selected tone scaling parameters; and
sending the packet from the transmitter to a receiver,wherein, when the frame format is the single user frame format, the selected tone scaling parameters include a signal field (SIG) tone scaling parameter that is different than a data portion tone scaling parameter for at least one of a plurality of bandwidths greater than one megahertz, andwherein, when the frame format is the multiple user frame format, the selected tone scaling parameters include;
a signal A field (SIG-A) tone scaling parameter that is different than the data portion tone scaling parameter for each of the plurality of bandwidths greater than one megahertz; and
a signal B field (SIG-B) tone scaling parameter that is the same as the data portion tone scaling parameter for each of the plurality of bandwidths greater than one megahertz.

Abstract
Systems and methods of controlling characteristics of messages in sub-1 GHz networks (e.g., IEEE 802.11ah networks) are disclosed. One or more data structures indicating tone scaling parameters may be stored at or accessible to transmitters and receivers. The data structures may be organized based on a frame format, a wireless network bandwidth, and/or the number of spatial streams in use at the wireless network. Information stored in the data structures may be used in generation and processing of messages communicated via the sub-1 GHz network.
