Patent number: 11956711Abstract: Certain aspects of the present disclosure provide techniques for an access point (AP) that does not use a flash memory for some storage (e.g., storing software images, logs, data, and other content used or generated by the AP) and file system operations (e.g., reading and writing dynamic files used by the AP). A method that may be performed, by an AP having a limited amount of flash memory, includes downloading a system image from a network entity, other than the AP, via a wireless network connection; and providing wireless local area network (WLAN) AP services using the downloaded system image.Type: GrantFiled: December 31, 2020Date of Patent: April 9, 2024Assignee: QUALCOMM IncorporatedInventors: Sreekanth Natarajan, Vairamuthu Karuppiah

Publication number: 20240098615Abstract: This disclosure provides systems and methods for use of automated frequency coordination (AFC) to manage transmission power and frequencies. In some implementations, a device transmits, to a network entity, an AFC request. The device receives, from the network entity, an AFC response, the AFC response including an AFC power level indication of one or more nearest neighboring entities. The device sets a transmit power of the device based at least in part on the AFC power level indication of at least one of the one or more nearest neighboring entities, and the device transmits at the transmit power. In some instances, the device transmits a first number of AFC requests during a first instance of travelling along a path and transmits a second number of AFC requests less than the first number of AFC requests during one or more successive instances after the first instance of travelling along the path.Type: ApplicationFiled: September 15, 2022Publication date: March 21, 2024Inventors: Subramanian ANANTHARAMAN, Sreekanth NATARAJAN, Sandip HOMCHAUDHURI, Sujatha VARADARAJAN

Publication number: 20240064668Abstract: This disclosure provides methods, devices and systems for access point (AP) steering or frequency band steering based on a location of a station (STA). In some aspects, an AP may determine the location of the STA based on timing information and may steer the STA based on the location. To obtain the timing information, the AP may exchange fine timing measurement (FTM) frames with the STA. The AP may determine a distance between itself and the STA based on the timing information. The AP also may obtain distance information from other APs. Using the distance between itself and the STA, as well as the distance information from other APs, the AP may determine a location of the STA and steer the STA based on its location. The AP may steer the STA to a different frequency band of the same AP or to different AP altogether.Type: ApplicationFiled: November 1, 2023Publication date: February 22, 2024Inventors: Prakash CHENNICHETTY, Manoj SEKAR, Thanigaivel NAGENDRAN, Subramanian ANANTHARAMAN, Sreekanth NATARAJAN

Publication number: 20230397026Abstract: This disclosure provides methods, apparatuses and systems for placing a range extender (RE) based on a distance between the RE and an access point (AP). An RE may determine a distance between the RE and AP based on round trip timing (RTT) information. In some aspects, the RE may exchange fine timing measurement (FTM) frames with the AP. The RE may determine a distance between itself and the AP based on the RTT information. Based on the distance between the RE and AP, the RE may provide a coarse placement indicator for improving the RE's location. The RE also may determine a signal strength or channel state information (CSI) with respect to the AP. Based on the signal strength or the CSI, the RE may provide a fine placement indicator indicating the RE may be placed nearer or further from the AP, or remain at its current location.Type: ApplicationFiled: August 16, 2023Publication date: December 7, 2023Inventors: Prakash CHENNICHETTY, Manoj SEKAR, Thanigaivel NAGENDRAN, Subramanian ANANTHARAMAN, Sreekanth NATARAJAN

Publication number: 20220376977Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for an internet of things (IoT) device. In some implementations, the IoT device can select an operating role for the first IoT device in a local network. The operating role may be selected from between an endpoint role and a relay role. The operating role may be dynamically selected by the first IoT device based whether the relay role would enhance connectivity for a client device that is within a wireless range of the first IoT device. The IoT device may participate in a self-organizing network (SON) and may coordinate with other devices in the SON to enhance wireless coverage for the client device based on a position of the client device relative to the one or more IoT devices.Type: ApplicationFiled: June 13, 2022Publication date: November 24, 2022Inventors: Subramanian Anantharaman, Sreekanth Natarajan

Publication number: 20190037613Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for an access point (AP) of a public wireless internet service provider (WISP) to authenticate a mobile device. The mobile device may provide a mobile subscriber identifier associated with a mobile network operator (MNO) that is different from the public WISP. The public WISP and MNO can coordinate the access credential so that the MNO is able to send the access credential to the mobile device if the MNO authorizes the use of the public WISP. The access credential may be sent using a messaging service, such as short message service (SMS). Using this technique, a subscriber of the MNO can obtain the AP access credential for the public WISP using a trustworthy delivery of the access credential by the MNO. The public WISP and MNO can monetize the internet access and authentication coordination workflow.Type: ApplicationFiled: July 31, 2017Publication date: January 31, 2019Inventors: Subramanian Anantharaman, Sreekanth Natarajan, Ponmudi Ramachandran

Publication number: 20150052569Abstract: The embodiments herein relate to a method and system for continuous detection of dead and impaired IPTV streams by introducing a hardware block to continuously monitor all IPTV streams for health without software intervention as disclosed in the embodiments herein. Each IPTV packet header is looked up in the multicast forwarding database (TCAM) table. When there are matching entries, the packets are metered and compared with the expected rate for the IPTV stream. A periodic scan of all the meters in hardware is carried out. If any stream is received less than its expected rate, an “impaired error” counter is incremented for the particular stream.Type: ApplicationFiled: February 20, 2013Publication date: February 19, 2015Applicant: Alcatel LucentInventors: Gopal Surya, Sreekanth Natarajan, Aravindan Jagannathan
