    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 available frame formats and/or timing 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.

    Abstract: Methods and devices for communicating in a communication system are described herein. One aspect of the subject matter described in the disclosure provides a method of communicating over one or more space time streams. The method includes transmitting a precoded portion of a first stream with a bandwidth of 1 MHz or less. The method further includes transmitting when there are at least two streams a precoded portion of a second stream with a cyclic shift delay relative to the first stream of 4 µs. The method further includes transmitting when there are at least three streams a precoded portion of a third stream with a cyclic shift delay relative to the first stream of 1 µs. The method further includes transmitting when there are at least four streams a precoded portion of a fourth stream with a cyclic shift delay relative to the first stream of 5 µs.

    Abstract: A method includes selecting a frame format for use in transmission of a packet via a wireless network. The transmission is associated with a particular bandwidth. The selected frame format is a first frame format if the particular bandwidth is equal to a threshold bandwidth. The selected frame format is the first frame format or a second frame format if the particular bandwidth is greater than the threshold bandwidth. The second frame format includes a first portion and a second portion. The first portion includes a short training field (STF), a long training field, and a signal A field, and the second portion includes a data portion including a second STF, one or more signal B fields, and a data field. The method further includes generating the packet in accordance with the selected frame format and one or more timing parameters and sending the packet.
