Innovation Solution
A wireless wide area network (WWAN) radio system that includes a WWAN modem, a WWAN transceiver, a multi-mode amplifier, and a high power port with a high power amplifier, frequency duplexer, and high power antenna, configured as a high power duplex chain, to enhance transmission power and range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If transmission power is increased to extend communication range, then range is improved, but battery life deteriorates and heat generation increases
Solution Approach 1:
The system dynamically switches between standard mode and high power mode amplifiers based on communication requirements. The WWAN transceiver can select appropriate transmission power levels, allowing the device to extend range when needed while conserving battery life during normal operation. This dynamic adaptation resolves the contradiction by making transmission power adjustable rather than fixed.
Solution Approach 2:
The patent implements multiple transmission power parameters through different amplifier modes. The high power port with high power amplifier provides elevated transmission power for extended range, while the standard mode maintains lower power for normal operation. This parameter change approach allows the system to achieve extended range when required without permanently increasing power consumption that would degrade battery life.
2Length of stationary object
If transmission power is increased to extend communication range, then range is improved, but heat generation increases
Solution Approach 1:
The system dynamically activates high power mode only when extended range is required, rather than continuously operating at high power. This dynamic switching reduces overall heat generation while still providing the capability for extended range communication when needed. The thermal load is managed by limiting high power operation to necessary periods only.
Solution Approach 2:
High power transmission is used periodically or intermittently based on communication needs rather than continuously. This periodic activation of the high power amplifier reduces cumulative heat generation while maintaining the ability to achieve extended range when required. The system alternates between standard and high power modes based on signal conditions and range requirements.
3Length of stationary object
If high power amplifier is added to extend range, then range is improved, but device complexity increases
Solution Approach 1:
The high power port and high power amplifier are integrated into the existing WWAN radio architecture, allowing the same device to function in both standard mode and high power mode. The multi-mode amplifier can operate in different power levels, and the high power antenna shares the same physical structure as standard antenna ports. This multi-functionality approach extends range capability without requiring completely separate high power equipment.
Solution Approach 2:
The patent merges the high power amplifier and high power antenna into the existing WWAN radio structure rather than using separate equipment. The high power port integrates with the WWAN transceiver, and the high power amplifier shares the same housing and control architecture as standard components. This merging reduces overall device complexity compared to using separate high power equipment while still achieving extended range capability.
