Location Dependent Data Transmission Using Beamforming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems that transmit location-dependent data to multiple receivers require substantial resources, especially when a large number of devices are present, as they often necessitate dedicated data streams from and to a base station, leading to inefficiencies and potential limitations in data transmission rates.
Innovation Solution
A system that transmits location-dependent data by dividing it into parts corresponding to different geographical regions, using a plurality of antennas and a processor to broadcast these parts to target locations within each region, thereby reducing resource usage and optimizing data transmission through techniques like beamforming and multipath propagation, allowing efficient communication even with a large number of receivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated data streams are used for each navigation device, then each device receives accurate location-dependent data, but resource consumption increases substantially when many devices are present
Solution Approach 1:
The patent segments location-dependent data into multiple parts, each corresponding to a different geographical region. Each part is transmitted to a specific target location within that region using beamforming. This allows multiple receivers in the same region to receive the required data parts without requiring dedicated streams to each device, thus reducing overall resource consumption while maintaining transmission accuracy.
2Reliability
If dedicated data streams are allocated to each receiver, then data transmission reliability is maintained, but system scalability is limited
Solution Approach 1:
The patent creates a universal transmission mechanism where a single base station can serve multiple receivers across different geographical regions simultaneously. By transmitting location-dependent data parts to multiple target locations using beamforming and multipath propagation, the system achieves multi-functionality, allowing it to scale to accommodate many receivers without requiring dedicated infrastructure for each device.
3Use of energy by moving object
If location-dependent data is transmitted to multiple target locations using beamforming, then resource usage is reduced, but system complexity increases
Solution Approach 1:
The patent replaces traditional mechanical or dedicated communication channel allocation with signal processing techniques such as beamforming and multipath propagation. Instead of physically allocating separate channels to each receiver, the system uses electromagnetic wave manipulation to direct data parts to multiple target locations simultaneously, reducing resource overhead while managing complexity through software-based signal control.

AI summary
The invention relates to a system (1) for transmitting location dependent data. The system comprises multiple antennas (3), a transmitter (5) coupled to the multiple antennas (3) and a processor (7). The processor (7) is configured to determine multiple location dependent parts of the location dependent data, each of the multiple location dependent parts corresponding to a different geographical region (8a-g, 25), and to use the transmitter (5) to transmit at least two of the multiple location dependent parts to a different target location (9a-g, 23) over the multiple antennas (3). Each of the at least two location dependent parts is associated with a different reference location (9a-g, 21) and the distance between a target location (9a-g, 23) and a reference location (9a-g, 21) associated with a location dependent part transmitted to the target location (9a-g, 23) is smaller than a predetermined threshold. The invention further relates to a device (17) for receiving location dependent data. The device (17) comprises a receiver and a processor. The processor is configured to use the receiver to receive a broadcast data stream comprising a first location dependent part of the location dependent data and a first identifier identifying the first location dependent part at a previous instance and a second location dependent part of the location dependent data and a second identifier identifying the second location dependent part at a current instance. The processor is further configured to detect a difference between the first identifier and the second identifier and to disregard the first location dependent part when the difference is detected. The invention further relates to the methods performed by the system and the device and a computer program product enabling a computer system to perform any of these methods.
