Abstract: Techniques are described for using a dedicated-scan radio to improve scanning and other radio operations performed during wireless communications. The techniques include configuring a dedicated-scan radio to collect and cache scan results without interfering with ongoing wireless communication tasks performed using primary radios. Based on the scan results cached by the dedicated-scan radio, the computing device improves other radio operations in furtherance of wireless communications. Cached scan results enable a primary radio to avoid, or to focus on, scanning certain channels or frequencies during discovering, positioning, or roaming operations. By using the dedicated-scan results as a starting point or seed for functions performed by a primary radio, the computing device may more quickly and more efficiently perform radio functions, minimizing latency to ongoing wireless communications.
