Embedded Access Point Dual-Mode Wireless Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless access points require a stationary power source and a limited operational range, restricting their mobility and usability in scenarios where a power source is unavailable or when devices are outside the operational range.
Innovation Solution
A low-power, small-footprint wireless access point with an embedded communication module that can establish connections with both a host device and another access point, allowing it to operate as both a station and an access point in different wireless networks, powered independently via a USB or SD connector, enabling connectivity beyond the traditional range limitations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wireless access point uses a stationary power source, then it can provide stable network access, but it cannot be used when no power source is available or when mobility is needed
Solution Approach 1:
The access point is integrated into a portable device that serves itself by using the device's existing power source, processor, and wireless communication capabilities to provide network access without requiring external power or infrastructure
Solution Approach 2:
The portable device performs multiple functions: it acts as both the host device and the wireless access point, enabling it to serve different roles (station and access point) within the same system
2Adaptability or versatility
If a wireless device connects to a stationary access point, then it can access the network, but it must be within a certain limited operational range
Solution Approach 1:
The network infrastructure is segmented from stationary access points to portable devices, allowing network access to be distributed across multiple mobile nodes rather than centralized at fixed locations
Solution Approach 2:
The system transitions from two-dimensional spatial coverage (stationary access point radiating in all directions) to mobile three-dimensional coverage (portable device moving through space, creating a dynamic network cloud that follows users)
3Ease of operation
If a wireless access point operates independently, then it can provide network access, but it requires external power and has a larger footprint
Solution Approach 1:
The access point functionality is merged with the portable host device, combining what were previously separate components (host device and access point) into a single integrated unit with shared hardware resources
Solution Approach 2:
The access point is nested within the portable device, with the access point functionality contained inside the host device's hardware and software architecture

AI summary
A device includes a first processing unit and an interface configured to communicate with an embedded access point including a wireless communication module configured to establish (i) a first wireless connection with a first station, and (ii) a second wireless connection with a separate access point. The device further includes a second processing unit configured to control a first wireless network including the device and the first station to operate the embedded access point as an access point for the first wireless network, and operate the embedded access point as a station in a second wireless network that includes the embedded access point and the separate access point. The separate access point provides access point functionality for the second wireless network, and the embedded access point is configured to be powered via the interface.
