Abstract: Methods, systems, and devices are described for estimating wireless local area network (WLAN) capacity. In accordance with the present disclosure, one or more applications associated with a mobile device may request WLAN capacity estimation in order to maximize the use of available network resources. In some examples, the mobile device may obtain WLAN information from a WLAN modem driver associated with a WLAN modem via an application program interface (API) to calculate the WLAN capacity. The WLAN capacity may include capacity of an access point (AP) associated with the mobile device to support additional users or data over one or more downlink and/or uplink channels. Accordingly, the mobile device may optimize data download or upload times by efficiently managing the available resources.
