Technologies directed to providing multimedia service over an extended range Wireless Local Area Network (WLAN) (e.g., IEEE 802.11ah) are described. In one method, a first wireless device identifies a first portion of media data as having a first priority value and a second portion of the media data as having a second priority value that is less than the first priority value. The first wireless device modulates the first portion to obtain first modulated data using a first modulation and coding scheme (MCS) that has symbol repetition and modulates the second portion to obtain second modulated data using a second MCS in which there is no symbol repetition. The first wireless device sends the first modulated data to a second wireless device in the wireless network and sends the second modulated data to the second wireless device after sending the first modulated data.

Multimedia service over an extended range wireless local area network (WLAN)using a modulation and coding scheme with symbol repetition for higher priority portions of media for data

Technologies directed to device detection and locationing are described. One method includes establishing a first wireless connection between a first wireless device and a second wireless device on a first channel. The first wireless device sends to the second wireless device a first indication that the first wireless device is to operate in an off-channel mode with a third wireless device at a first location a Fine Timing Measurement (FTM) procedure. The first wireless device performs a first FTM process between the first wireless device and the third wireless device. The first device determines first timing data including a signal round trip time (RRT) associated with the first FTM process and determines a first distance between the first wireless device and the third wireless device based on the first timing data. A second location of the first wireless device is determined using the first distance.
