Monisha Ghosh is a renowned inventor and engineer in the field of wireless communications. She is based in Chappaqua, New York and has an impressive number of 74 patents to her name. Her latest patents highlight her expertise in the sectorization coordination of wireless transmissions, power control, and clear channel assessment.
The first patent involves a method and apparatus supporting coordinated and cooperative sectorized transmissions. In this patent, Ghosh outlines a technique for using power control and clear channel assessment to support sectorized transmissions. The transmissions are protected by a first access point (AP), which sends both an omni-directional transmission and a beamformed or sectorized transmission to a station (STA). An overlapping basic service set (OBSS) confirms a spatially orthogonal (SO) condition based on the omni-directional transmission, and a second AP monitors the omni-directional transmission and confirms the SO condition. The STA may then receive a request-to-send (RTS) frame indicating data is available for transmission and transmit a cooperative sectorized (CS) clear-to-send (CTS) frame, indicating an ability for multiple AP reception.
Ghosh's second patent involves a clear channel assessment (CCA) threshold adaptation method. This patent outlines the use of methods and apparatus for adapting clear channel assessment (CCA) thresholds with or without transmit power control (TPC). In this method, an IEEE 802.11 station (STA) may dynamically calculate a STA-specific TPC value and a STA-specific CCA value based on a target TPC parameter and a target CCA parameter. The target TPC parameter and the target CCA parameter may be received from an IEEE 802.11 cluster head configured to control TPC and CCA for a plurality of STAs associated with the BSS. The STA may then determine whether a carrier sense multiple access (CSMA) wireless medium of a wireless local area network (WLAN) basic service set (BSS) is occupied or idle based on the STA-specific CCA value.
