Innovation Solution
A signal transforming and transmitting apparatus and method that defines signal-download and signal-upload periods based on a clock signal, using a processing chip and a signal dividing/integrating unit to differentiate and integrate wired and wireless signals, allowing for simultaneous transmission and reception of signals between a base station and downstream devices, effectively combining the functions of a repeater and a modem.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a user uses a wired network to achieve high transmission rate and reliability, then the transmission reliability is improved, but the mobility is worsened due to wiring layout restrictions
Solution Approach 1:
The patent combines the functions of a repeater and a modem into a single integrated apparatus. The repeater function provides wireless signal amplification and extended coverage, while the modem function enables wired network connection. This merging allows the system to simultaneously provide mobility (through wireless repeater functionality) and reliable wired connectivity (through modem functionality), resolving the contradiction between mobility and transmission reliability.
2Ease of operation
If a user uses a wireless repeater to achieve mobility and extended coverage, then the ease of operation is improved, but the signal reliability is worsened compared to wired networks
Solution Approach 1:
The integrated apparatus merges repeater and modem functions, allowing users to maintain mobility benefits of wireless operation while simultaneously accessing reliable wired network connections through the modem component, thus improving signal reliability without sacrificing mobility.
Solution Approach 2:
The modem acts as an intermediary between the wireless repeater system and the wired network infrastructure. It transforms wireless signals to wired signals, providing a reliable wired connection path while the repeater handles wireless signal propagation, thus mediating between the reliability requirements of wired networks and the mobility requirements of wireless systems.
3Reliability
If a user purchases both a repeater and a modem to achieve both mobility and reliability, then the signal transmission quality is improved, but the device complexity and cost are worsened
Solution Approach 1:
The patent integrates the repeater and modem into a single unified apparatus with shared hardware resources including antenna, amplifier, processor, and power management circuitry. This merging eliminates the need for users to purchase and carry two separate devices, reducing device complexity while maintaining both wireless repeater functionality for mobility and modem functionality for reliable wired connectivity.
Solution Approach 2:
The integrated apparatus is designed with multi-functionality, serving both as a wireless repeater and as a modem. The single device can operate in different modes (wireless repetition mode and wired network mode) depending on operational requirements, providing universal functionality that replaces the need for multiple specialized devices, thus reducing overall system complexity and cost.
4Productivity
If simultaneous signal upload and download are implemented, then the data transmission efficiency is improved, but signal interference is worsened
Solution Approach 1:
The patent implements periodic time-division operation for signal upload and download. The processor alternates between receiving/downloading signals during designated time periods and transmitting/uploading signals during other designated time periods. This periodic action prevents simultaneous transmission and reception that would cause signal interference, while still achieving efficient data transmission through the alternating time slots dedicated to each direction of communication.

AI summary
A signal transforming and transmitting apparatus and a signal transforming and transmitting method are provided. The signal transforming and transmitting apparatus includes a processing chip, and a signal dividing/integrating unit. The processing chip defines a signal-download period and a signal-upload period according to a clock signal. The signal dividing/integrating unit is coupled to the processing chip, and is adapted for dividing a wired downloading signal from a wireless downloading signal transmitted from the base station during the signal-download period, and transmitting the wired downloading signal and the wireless downloading signal to corresponding downstream devices. The signal dividing/integrating unit is adapted for integrating a wired uploading signal and a wireless uploading signal into an integrated wireless uploading signal and transmitting the integrated wireless uploading signal to the base station, during the signal-upload period. In such a way, the present invention avoids the interference caused by overlaps between uploading and downloading operations.
