Publication number: 20240040424Abstract: A Wi-Fi device in a WLAN network includes a processor and a transceiver adapted to be coupled to an antenna, and a power saving medium access in congested network environments algorithm that is activated after a Wi-Fi connection is established with its access point (AP). A Traffic Indication Map (TIM) bitmap in a TIM information element received in a beacon frame from the AP is analyzed to determine whether more than a predetermined number of bits (X) are set to indicate the AP has ?1 buffered frame for ones of the Wi-Fi devices to conclude whether the WLAN is in a congested environment. When in a congested environment, transmissions responsive to the beacon are postponed by entering a sleep mode for a random period of time (P). After P expires, the sleep mode is exited and a poll frame is transmitted to the AP to try to gain medium access.Type: ApplicationFiled: October 13, 2023Publication date: February 1, 2024Inventors: Oran Naftali, Uri Weinrib, Oren Shani

Publication number: 20240015652Abstract: According to an embodiment, a system and method is disclosed for efficient wake up in a wireless communication device for receiving beacons without significantly affecting the battery power and data throughput. Wireless device receives beacons from network elements such as access points. If beacons are not received as scheduled within defined intervals, then the wireless device determines a pattern of beacon reception timings and uses a weighted score process to select the best possible reception timing pattern and uses it as the schedule for receiving beacons on going forward basis, thus avoiding staying awake at all time to receive misaligned beacons.Type: ApplicationFiled: September 20, 2023Publication date: January 11, 2024Inventors: ORAN NAFTALI, YUVAL JAKIRA, LIRAN BRECHER, ASAF EVEN-CHEN

Publication number: 20240015651Abstract: A controller is arranged to: receive a first decoded beacon frame which includes a first indication of a first data transmission; receive a second decoded beacon frame which includes a second indication of a second data transmission; compare the first and second decoded beacon frames to determine common bytes in the first and second decoded beacon frames; determine an expected time of receiving the common bytes in a third beacon frame; control a device to enter into a low power mode; and control the device to wake up from the low power mode at a time to receive and decode at least a portion of the third beacon frame, in which the time to wake up is based on the expected time to receive the common bytes instead of based on an expected time to receive a preamble at a start of the third beacon frame.Type: ApplicationFiled: September 20, 2023Publication date: January 11, 2024Inventors: Oran Naftali, Avi Baum, Yuval Jakira, Asaf Even-Chen
