Patent number: 12261639Abstract: A wireless communication is proposed that utilizes a large available bandwidth (e.g., 10-100,000 MHz) and employs a combination of frequency shifting (from an input RF signal to an IF signal) and frequency hopping from one IF frequency value to another within the available bandwidth. The combination of frequency shifting and frequency hopping adds a level of noise mitigation moving the transmission frequency as a function of time (and avoiding frequencies known to be subject to noise). By its nature, the addition of frequency hopping frustrates the ability of outsiders to access transmissions. A map of frequencies to be used may be delivered to both the transmitter and receiver via a separate command/control signal path. Alternatively, a transmitter may develop the map and forward it to the receiver. The frequency hopping sequence is preferably a randomly-generated sequence that uses the entire available bandwidth.Type: GrantFiled: September 4, 2024Date of Patent: March 25, 2025Assignee: Doodle Labs LLCInventors: Nimesh D.

Patent number: 11930430Abstract: An application-specific wireless communication network for use in an industrial environment based on parameters defined by the IEEE 802.11 standard, modified by providing software-defined control of an assigned operating frequency band and software-defined control of the channel size, allowing the channel size to be relatively small as appropriate for the particular industrial application. The application-specific wireless communication network further controls other parameters defined by the standard to configure at least optimum transmitter power, receiver sensitivity, transmission latency, and ACK-retransmit to values appropriate for the specific industrial application.Type: GrantFiled: July 18, 2019Date of Patent: March 12, 2024Assignee: Doodle Labs (SG) PTE LTD.Inventors: Nimesh D.

Patent number: 11611363Abstract: A radio module is configured to operate within a specialized frequency band, for example a band that has recently become available for use in the public domain. Superheterodyne techniques are used by a transmitter component of the radio module to frequency shift a conventional wireless data signal (e.g., used for WiFi, LTE telecommunications, etc.) into a designated band; a receiver component of the radio module is similarly configured to receive signals transmitted on the designated band and shift back into the conventional RF band (where standard components are able to further process the received signal).Type: GrantFiled: September 9, 2019Date of Patent: March 21, 2023Assignee: Doodle Labs (SG) PTE LTDInventors: Nimesh D. Parikh, Claus Muschallik, Meng Huan Gan, Aaron Vinh Thanh Do, Sameer Garg

Publication number: 20220286864Abstract: An apparatus for shared spectrum access (referred to at times hereinafter by the acronym “ASSA”, or more generally, as a “gateway device”) is configured to work with one or more private networks, providing control of operating parameters such as the assignment of a specific frequency band (channel), maximum level of transmission power at an assigned channel, and/or even the ability to use a shared spectrum assignments, updating as need be. By virtue of provisioning end-user devices (EUDs) with software-defined transceivers, the ASSA may function to broadcast “operation parameters” (i.e., assigned frequency band and maximum transmission power) to all EUDs within its range. The EUDs may be fixed or mobile devices.Type: ApplicationFiled: August 3, 2020Publication date: September 8, 2022Applicant: Doodle Labs (SG) PTE LTDInventors: Nimesh D.
