Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication technologies face challenges in securely transmitting sensitive data, particularly personal data, due to vulnerabilities in security and dependence on infrastructure, with known technologies like Bluetooth, WLAN, or GSM being susceptible to attacks and interference.
Innovation Solution
A mobile, portable UWB communication device employing multiple UWB data coding schemes for secure data transmission, where different data sets are encoded using distinct schemes, making them undetectable to unauthorized parties and maintaining channel security even if one scheme is compromised, utilizing UWB's wide frequency range and noise-like appearance to enhance security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple UWB data coding schemes are used for different data types, then data security and undetectability are improved, but device complexity increases
Solution Approach 1:
The patent segments data transmission into multiple independent UWB communication channels, each using a different data coding scheme. This allows different data types to be transmitted securely without interfering with each other. Each channel can be independently managed and secured, resolving the contradiction by organizing complexity into structured segments rather than a monolithic system.
Solution Approach 2:
The UWB communication device is designed to support multiple data coding schemes universally, enabling it to handle various data types (e.g., location data, communication data, sensor data) with different security requirements through a single multi-functional platform. This universality allows the system to maintain security without requiring separate dedicated systems for each data type.
2Productivity
If multiple UWB communication channels are established simultaneously, then data transmission capacity and independence are improved, but detection difficulty for unauthorized parties increases
Solution Approach 1:
Each UWB communication channel is assigned a specific local quality characteristic through its data coding scheme, making it distinguishable only to authorized parties who know the corresponding coding scheme. The channels operate independently with unique properties that prevent unauthorized detection, while maintaining high transmission capacity through parallel operations.
Solution Approach 2:
The patent uses coded versions of UWB signals as copies of the original transmission, where the coding scheme acts as a key. Authorized receivers with the correct key can decode and recognize the signal, while unauthorized parties see only scrambled data. This copying mechanism enables multiple simultaneous channels without increasing detectability to outsiders.

AI summary
The invention relates to a mobile portable UWB communication device (112), wherein the UWB communication device (112) comprises a processor (130), a memory (132), and a communication interface (134). The memory (132) stores a plurality of UWB data encoding schemes (150), comprising at least a first UWB data encoding scheme (152) and a second UWB data encoding scheme (154) different from the first UWB data encoding scheme (152). Furthermore, the memory (132) stores a plurality of data (140), comprising at least first and second data (142, 144), wherein the first data (142) are assigned to the first UWB data encoding scheme (152) and the second data (144) are assigned to the second UWB data encoding scheme (154). To transmit the first data (142) with a first UWB data encoding, a first UWB communication is performed, which is encoded according to the first UWB data encoding scheme (152).To transmit the second data (144) with a second UWB data encoding different from the first UWB data encoding, a second UWB communication is carried out, which is encoded according to the second UWB data encoding scheme (154).
