Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network devices face challenges in minimizing interference with structural components when transmitting wireless signals, particularly in home wireless local area networks, due to the placement of antennas within electrical boxes and wall materials, which limits wireless coverage and range.
Innovation Solution
The development of in-wall network devices with a wireless antenna positioned outside the wall to minimize interference, using configurations such as multiple antennas for different frequencies and polarities, and employing antenna designs like inverted F antennas and microstrip patch antennas to achieve optimal propagation characteristics without increasing output power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the wireless antenna is positioned inside the electrical box or behind wall components, then the device complexity is reduced, but the wireless signal transmission is interfered with by structural components
Solution Approach 1:
The wireless antenna is extracted from the interior of the electrical box and repositioned to the exterior surface of the housing. This allows the antenna to operate in a location free from interference by wall components such as sheet rock, plaster, and electrical wiring, while still maintaining integration with the in-wall network device.
Solution Approach 2:
A transmission line serves as an intermediary component that connects the wireless transceiver inside the electrical box to the wireless antenna positioned outside on the housing surface. This mediator enables the separation of the antenna from the device interior while maintaining functional connection.
2Area of stationary object
If the wireless antenna is positioned outside the wall, then the wireless coverage and transmission range are improved, but the device complexity increases
Solution Approach 1:
The wireless antenna is designed with multi-frequency capability, allowing a single antenna structure to operate across multiple frequency bands (e.g., 2.4 GHz and 5 GHz WiFi bands). This eliminates the need for separate antennas for each frequency, reducing overall device complexity while maintaining broad wireless coverage.
