Patent number: 12587874Abstract: A method for fabricating a window mounted Wi-Fi gateway system, where the method comprises orienting a transparent and substantially flat platform in a horizontal orientation, applying transparent sheet material to each side of the platform, placing first and second optical couplers (OC) perpendicularly on opposing sides of the transparent sheet material, placing a first form on first transparent sheet material, depositing a first stabilizer material within the first form, and turning the platform over a first time. The method further comprises placing a second form on second transparent sheet material wherein the first form and the second form are substantially aligned with each other, depositing a second stabilizer material within the first form, attaching wireless power coils to the second stabilizer material, turning the platform over a second time, attaching wireless power coils to the first stabilizer material, removing the transparent sheet material from the platform, and removing the forms.Type: GrantFiled: December 6, 2023Date of Patent: March 24, 2026Assignee: T-Mobile USA, Inc.Inventor: Chad Au

Publication number: 20260045703Abstract: Electronic devices include a transmitter portion that includes one or more antennas and a receiver portion that includes one or more Rydberg sensors. The Rydberg sensors are configured to receive radio frequency (RF) signals. The Rydberg sensors are a much more sensitive mechanism for the detection of miniscule electromagnetic fields in comparison to typical antennas. The transmitter portion transmits RF signals via the one or more antennas.Type: ApplicationFiled: August 8, 2024Publication date: February 12, 2026Inventor: Chad Au

Publication number: 20250338256Abstract: Techniques for presenting a symbol on a display of a wireless device indicative of wireless resources based on network states and device states are discussed herein. In some example, the techniques include determining when to scan for wireless resources and/or which of multiple network identifiers to display on a status bar of the device, when the device is operating in a cellular network of a wireless communications provider that has areas of coverage provided by a non-terrestrial network. In some examples, a symbol indicative of a wireless resource can be determined based at least in part on a policy, which may be based on device characteristics and/or an availability or non-availability of one or more radio frequency resources. Network identifiers might include, for example, symbols that indicate 3G, 4G, LTE, 5G, 5G non-terrestrial networks (NTN) and so forth, corresponding to different wireless network standards.Type: ApplicationFiled: April 30, 2024Publication date: October 30, 2025Inventors: Chad Au, Gaviphat Lekutai, Jun Liu, Kun Lu

Publication number: 20250307578Abstract: Techniques and architecture are described for integrating radio frequency identification (RFID) reader functionality into mobile communication devices, e.g., smartphones. By integrating RFID reader functionality into smartphones, which already have much of the RF equipment (transmitter, receiver, (transceiver), antenna), processing power, and connectivity needed as a self-contained, contactless-enabled, RFID terminal, prior art RFID terminal peripherals would become unnecessary. For example, integrated RFID terminal capabilities in smartphones may be used to conduct mobile contactless transactions, such as by tapping a credit card or debit card on the smartphone screen, much like when making purchases in stores today.Type: ApplicationFiled: March 26, 2024Publication date: October 2, 2025Inventor: Chad Au

Publication number: 20250240095Abstract: A self-aligning window mounted communication apparatus is discussed herein. In some examples, a wireless gateway may comprise a first unit to be mounted outside a window and a second unit to be mounted inside the window. A first unit and a second unit may each include an optical unit, a coupling unit, and a housing unit. A first optical unit may include a magnetic array with polarities of the magnetic elements configured to orient with a second optical unit in a single orientation. The optical unit(s) may be movably coupled with the respective coupling unit(s) so that the optical unit may move with various degrees of freedom and thus, when the first and second units are mounted on a window, the optical units can self-align based on the respective magnetic arrays and the degrees of freedom afforded by the movable coupling with the coupling unit.Type: ApplicationFiled: January 19, 2024Publication date: July 24, 2025Inventors: Long Ching Macor Ho, Chad Au

Publication number: 20250184808Abstract: Techniques and architecture discussed herein describe applications (apps) that allow devices, e.g., mobile devices such as smartphones, tablets, etc., that are out of wireless network coverage to communicate or coordinate with other mobile devices within detectable range, in essence forming a local area network (LAN), by exploiting the Third Generation Partnership Project (3GPP) sidelink feature and geolocation capabilities of the mobile devices. Teams of users may spread out over a specified area and be informed about team members' locations relative to theirs, as well as their up-to-the-minute status or other inputs. More particularly, the 3GPP standard has an “off-network” feature called “sidelink” that can facilitate device-to-device communication without the need for a network connection, e.g., the mobile devices may function similar to walkie talkies.Type: ApplicationFiled: December 4, 2023Publication date: June 5, 2025Inventor: Chad Au

Patent number: 11469503Abstract: An antenna system including one or more a frequency responsive components (FRCs) may employ filters to one or more paths in the antenna system corresponding one or more radiating elements on those paths. The FRCs can block a signal from reaching the radiating elements effectively causing the radiating elements to become non-contributing to the antenna systems radiating pattern performance, and thus, maintain a consistent aperture value associated with the antenna system. In some cases, the FRCs may be configured to block a signal when the antenna system is operating at a particular frequency.Type: GrantFiled: February 28, 2020Date of Patent: October 11, 2022Assignee: T-Mobile USA, Inc.Inventor: Chad Au

Patent number: 11189938Abstract: Low-profile end-fire antenna systems to provide additional throughput in areas of need with minimal structural and aesthetic impact. The system can include one or more low-profile end-fire antennas mounted to an exterior surface (e.g., a roof or parapet) of a building, parking deck, exiting cell tower, water tower, or other suitable structure. Additional electronics can be remotely mounted to maintain the low profile of the system. The system can be color-matched, or otherwise camouflaged, to maintain building aesthetics. The low-profile end-fire antenna can be mounted on a positioning stand to enable the elevation and/or azimuth of the system to be adjusted. The low profile of the antennas can reduce wind loading and enable the system to be mounted to existing structures without reinforcement, or other modification, to the structure. The orientation of the system relative to observers in many locations (e.g., on the ground) renders the system all but invisible.Type: GrantFiled: February 26, 2020Date of Patent: November 30, 2021Assignee: T-Mobile USA, Inc.Inventor: Chad Au

Patent number: 10873885Abstract: A wireless communication system may support two types of networks, such as a 4th-Generation (4G) network and a 5th-Generation (5G) network. The 4G network is accessed through Long-Term Evolution (LTE) base stations. The 5G network is accessed through New Radio (NR) base stations. During idle mode, a communication device may scan 5G RF frequencies to determine whether a 5G signal is available and whether to display a 5G network symbol in the status bar of the device. The communication device is configured to detect conditions indicating whether a user of the device is likely viewing the device and/or the display of the device. If it is unlikely that the user is viewing the device or its screen, RF frequency scanning is paused to reduce power consumption and the currently displayed network symbol is maintained until RF frequency scanning is resumed.Type: GrantFiled: April 8, 2019Date of Patent: December 22, 2020Assignee: T-Mobile USA, Inc.Inventors: Chad Au, Kun Lu, Ming Shan Kwok, Jun Liu, Egil Gronstad, Alan Denis MacDonald, John J.
