Short-Range Signal Pairing for Wireless Transmitter Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In environments like gyms, it is challenging to determine which transmitter apparatus should pair with a specific receiver apparatus due to the numerous transmitter devices present, as existing technologies do not effectively differentiate between multiple radio signals, leading to confusion and inefficiency in establishing the correct wireless communication link.
Innovation Solution
The use of a short-range signal to indicate the reception timing and radio resource for a radio signal, allowing the receiver apparatus to synchronize and decode the correct radio signal, thereby facilitating pairing by distinguishing between multiple transmitter devices based on the unique characteristics of the short-range signal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple transmitter apparatuses are present in a gym environment, then the coverage area and connectivity options are improved, but the difficulty of detecting and measuring which transmitter should pair with a specific receiver increases
Solution Approach 1:
The communication system is segmented into two distinct phases: a short-range signal phase for transmitter identification and pairing, and a long-range radio signal phase for data transmission. This segmentation allows the receiver to first identify the correct transmitter using short-range signals before establishing full communication, resolving the ambiguity in multi-transmitter environments.
Solution Approach 2:
A short-range signal acts as an intermediary between the transmitter and receiver. This intermediary signal carries identification information and pairing data, enabling the receiver to distinguish between multiple transmitters and establish the correct connection before full radio communication begins.
2Productivity
If the receiver apparatus continuously monitors for radio signals from multiple transmitters, then the productivity of establishing connections is improved, but the use of energy increases
Solution Approach 1:
The receiver performs preliminary action by first detecting short-range signals from potential transmitters to identify and pair with the correct device before initiating full radio signal reception. This preliminary identification step allows the receiver to focus its energy on a specific transmitter rather than continuously monitoring all possible transmitters.
Solution Approach 2:
The system dynamically switches between short-range signal mode for identification and long-range radio signal mode for data transmission. The receiver adjusts its monitoring behavior based on the current phase, reducing energy consumption during the identification phase while maintaining high productivity during the data transmission phase.
3Measurement precision
If the receiver uses short-range signals to identify transmitters, then the measurement precision of transmitter identification is improved, but the communication range is limited
Solution Approach 1:
The communication process is divided into two segments with different range characteristics: short-range signals for precise transmitter identification and long-range radio signals for data transmission. This segmentation allows the system to achieve high identification precision using short-range signals while maintaining broad connectivity through long-range radio communication.
Solution Approach 2:
The system transitions from a short-range identification dimension to a long-range data transmission dimension. By separating the identification function from the data transmission function, the system can optimize each dimension independently, achieving precise identification within short range while maintaining extended communication capability.

AI summary
This document presents a wireless communication scheme utilizing a combination of two wireless communication schemes: a short range communication scheme and a radio communication scheme having a longer wireless transmission range than the wireless transmission range of the short range communication scheme. A short range signal is used to indicate a radio resource to be used for transmitting a radio signal, and the radio signal is then communicated in the radio resource indicated by the short range signal.
