Abstract:
1. A method comprising: selecting, at a transmitter, a frame format for use in communicating a packet via a sub-one gigahertz wireless network operating at a particular bandwidth, wherein the frame format is selected based at least in part on the particular bandwidth; determining one or more timing parameters based on the selected frame format and the particular bandwidth; generating the packet in accordance with the selected frame format and the one or more timing parameters; and sending the packet from the transmitter to a receiver, wherein the selected frame format is a first frame format when the particular bandwidth is one megahertz, wherein the selected frame format is the first frame format or a second frame format when the particular bandwidth is greater than one megahertz, wherein the second frame format comprises a first portion and a second portion, wherein the first portion comprises an omni portion comprising a short training field (STF), a first long training field (LTF), and a signal A field (SIG-A), and wherein the second portion comprises a data portion comprising a second STF, one or more signal B fields (SIG-Bs), and a data field.
