Wireless Network Initial Access via Threshold Distance Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Longer range Wi-Fi routers increase the risk of unauthorized access due to their greater range, allowing hackers to connect from farther distances, compromising network security.
Innovation Solution
Implementing a system where devices can initially access a wireless network only within a threshold distance using specific communication protocols, and then permit communication beyond that distance using a different protocol, ensuring secure authentication and access.

1Area of stationary object
If longer range Wi-Fi routers are used to extend network coverage, then the network range is improved, but the security against unauthorized access deteriorates
Solution Approach 1:
The authentication process is segmented into two distinct phases: initial authentication within a first threshold distance using a first communication protocol, and subsequent communication beyond the threshold using a second communication protocol. This segmentation allows the system to maintain security during initial access while enabling extended range communication for authenticated devices.
Solution Approach 2:
Different communication protocols are applied at different spatial locations relative to the router. The first communication protocol is used locally within the first threshold distance for authentication, while the second communication protocol is used at distant locations beyond the threshold for ongoing communication. This local quality differentiation ensures secure authentication close to the router while allowing wide-area access for authenticated devices.
2Ease of operation
If devices are permitted to access the network from beyond threshold distance, then the ease of operation is improved, but the network security deteriorates
Solution Approach 1:
The system performs preliminary authentication action within the first threshold distance before allowing communication beyond that distance. By completing the authentication process (first communication protocol) within the secure near-field region, the system ensures that only authenticated devices can subsequently access the network from distant locations using the second communication protocol.
Solution Approach 2:
The first communication protocol acts as an intermediary authentication mechanism between the device and the router. This intermediary protocol verifies device identity and authorization within the near-field before allowing the second communication protocol to enable distant communication, thus mediating between security requirements and accessibility needs.

AI summary
In one aspect, a first device includes a processor, at least one wireless communication transceiver, and storage accessible to the processor. The storage bears instructions executable by the processor to operate a wireless network using the at least one wireless communication transceiver, permit a second device to initially access the wireless network based at least in part on the second device being within a threshold distance to the first device, and permit the second device to communicate with at least a third device through the wireless network from beyond the threshold distance.
