Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques are limited in facilitating efficient communication between wireless devices using different wireless protocols, particularly different versions of a wireless protocol, such as Bluetooth classic and Bluetooth Low Energy, within environments like automobile cabins.
Innovation Solution
Wireless devices are configured with a dual-mode controller to perform translation and relay operations, managing these functions within the baseband controller layer without involving the application or host layers, enabling communication between devices using disparate protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional techniques are used for wireless communication between devices with different protocols, then device compatibility is poor, but system complexity remains low
Solution Approach 1:
The patent introduces a relay device as an intermediary component that receives signals from a first wireless device using a first protocol, translates them, and transmits to a second wireless device using a second protocol. This intermediary relay device enables communication between devices with different protocols without requiring the devices themselves to be complex multi-protocol devices, thus improving adaptability while managing complexity through specialization.
2Adaptability or versatility
If translation operations are performed at application or host layers, then protocol compatibility is achieved, but processing overhead and latency increase
Solution Approach 1:
The patent extracts the translation function from the application layer and host layer of the wireless protocol stack and implements it independently in the relay device. This separation allows the main devices to focus on their primary functions while the relay device handles protocol translation, reducing processing overhead and latency in the original devices.
Solution Approach 2:
The relay device performs protocol translation in advance before data reaches the application layer, preparing translated data packets ahead of time. This preliminary action ensures that when data needs to be transmitted between different protocol domains, the translation is already complete, reducing real-time processing delays.
3Adaptability or versatility
If relay operations involve application and host layers, then protocol compatibility is improved, but operational complexity and power consumption increase
Solution Approach 1:
The patent implements protocol translation and relay operations at the link layer, which is a localized layer in the wireless protocol stack, rather than involving the entire application and host layers. This localized approach limits the scope of operations to only what is necessary for protocol translation, reducing unnecessary processing and associated power consumption while maintaining cross-protocol communication capability.

AI summary
Systems, methods, and devices include wireless relays for wireless communication. Methods include receiving an input via a first wireless connection at a wireless device, the input comprising a first data packet compatible with a first wireless protocol, and identifying a second wireless connection compatible with a second wireless protocol based on the received input. Methods further include generating, using a dual-mode controller of the wireless device, an output based, at least in part, on the received input and the second wireless protocol, the output comprising a second data packet compatible with the second wireless protocol, and transmitting the output via the second wireless connection using the second wireless protocol.
