Using Millimeter Waves to Map Your Surroundings for Better Location
This patent describes a way for a mobile device to use millimeter wave signals to understand its environment and pinpoint its location by analyzing how those signals bounce off surfaces.
Original patent title: “System, method and computer-accessible medium for real time imaging using a portable device”
This patent describes a way for a mobile device to use millimeter wave signals to understand its environment and pinpoint its location by analyzing how those signals bounce off surfaces. Owned by New York University NYU with 22 claims and 2 forward citations, and it is expected to expire in 2043.
Coverage
What does this patent actually cover?
This invention uses millimeter wave (mmWave) radio frequency signals to create a map and determine a device's location. A transmitting device sends out these signals, which then bounce off surfaces like walls or furniture, creating 'multipath components.' The device receives these bounced signals and analyzes information from them, such as the angle they arrived (AoA) or when they arrived (time of arrival). Using this data, along with a stored map, a ray tracing process calculates the device's precise location. It can then generate images or video of the surroundings, potentially showing other objects in the environment. For example, a phone could use this to show a user exactly where they are in a large building or to highlight obstacles.
The gap
What does this patent NOT cover?
- Methods that do not use millimeter wave (mmWave) radio frequency signals.
- Systems that do not analyze multipath components of the RF signal.
- Methods that do not determine at least two pieces of information like AoA, AoD, time of arrival, RTA, or phase.
- Techniques that do not use a stored 2D or 3D map of the environment.
- Processes that do not employ a ray tracing calculation to determine location.
These exclusions are unique to PatentBrief — derived from the actual claim language, not patent-office boilerplate.
Key facts
What made this novel
The innovation lies in combining mmWave signal analysis with existing map data and ray tracing. This allows for precise localization by understanding how the signals interact with the physical environment, rather than relying solely on satellite signals which fail indoors.
