Techniques for indication of wireless signal quality are described. According to various implementations, attributes of a wireless signal are detected and processed to ascertain a quality of the wireless signal. Based on an ascertained signal quality, indicia of the signal quality can be exposed. For instance, an indication of wireless signal quality is communicated to an application and/or service that manages communication of media data. According to one or more embodiments, an application/service may perform one or more actions based on the indication of signal quality, such as a procedure to improve signal quality, a procedure to optimize wireless performance, and so forth.
