US 2026/0255281 A1 · WIRELESS LOCAL AREA NETWORK THROUGHPUT AND COVERAGE WITH ENHANCED SPECIFIC ABSORPTION RATE

Abstract

Methods, systems, and devices for wireless communications are described. An access point (AP) and a station (STA) may communicate frames in accordance with a specific absorption rate (SAR) limit. An AP or STA may suspend or modify an SAR limit to support communicating frames having relatively higher transmission powers. For example, the AP or STA may modify an SAR limit for a time interval (for example, a time-averaged SAR limit) such that the AP or STA may increase a transmission power of a data frame. In some examples, the AP or STA may modify a duty cycle associated with the data frame based on modifying the SAR limit for the time interval. Additionally or alternatively, the AP or STA may suspend an SAR limit (for example, a transmission power threshold associated with the SAR limit) such that the AP or STA may increase a transmission power of a control frame.
