Wireless Building Access Control With Mobile Location Tailgating Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current physical access control systems relying on physical access cards are cumbersome, time-consuming, and prone to errors, and lack effective detection of tailgating events.
Innovation Solution
Utilizing mobile devices as access credentials through wireless communication with wireless access points, where unique IMEI-based identifiers and location data are used to control access and detect unauthorized entry, with sensors monitoring for tailgating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical access cards are used for building access control, then access authorization can be managed, but the system becomes cumbersome, time-consuming and error-prone
Solution Approach 1:
The patent replaces physical access cards with mobile devices using wireless communication technology. The mobile device transmits unique identifiers (such as IMEI) wirelessly to access control readers, eliminating the need for physical card swiping. This substitution reduces operational complexity and time consumption while maintaining secure access control functionality.
Solution Approach 2:
The patent enables mobile devices to serve multiple functions: they act as access credentials, provide location tracking, and enable automated access decisions. A single mobile device replaces the dedicated physical access card, offering universal functionality across different access points and eliminating the need to manage separate physical credentials.
2Reliability
If physical access cards are used, then access control is implemented, but the system lacks effective detection of tailgating events
Solution Approach 1:
The patent implements a feedback mechanism where wireless access points continuously track the location of mobile devices. When an authorized user triggers door unlock, the system monitors whether additional unauthorized devices enter the secure area. This real-time location feedback enables automatic detection of tailgating events and triggers appropriate security responses.
Solution Approach 2:
The patent introduces wireless access points and location tracking technology as intermediaries between the access control system and tailgating detection. These intermediaries monitor device locations and provide data to the access control system, enabling indirect detection of tailgating events without requiring direct physical intervention or additional sensors at the door.
3Productivity
If mobile devices are used as access credentials, then access control is streamlined, but the system must detect and prevent unauthorized tailgating entry
Solution Approach 1:
The patent enables the access control system to automatically monitor and detect tailgating events without requiring additional manual intervention. The wireless access points continuously track mobile device locations and automatically identify when unauthorized devices enter secure areas, allowing the system to self-monitor and self-report security incidents.
Solution Approach 2:
The patent implements preliminary location tracking of mobile devices before access decisions are made. The system pre-establishes the locations of authorized and unauthorized devices, so when a door is unlocked, it can immediately determine whether additional unauthorized devices are present. This preliminary action enables rapid automated response without complex real-time analysis.

Function Achieved in This Case
Streamlines access control by eliminating the need for physical badges and effectively detects tailgating events, enhancing security and efficiency.
Implementation Method 1
establishing a wireless communication between one or more wireless access points and each of a plurality of mobile devices
Implementation Method 2
One or more of the wireless access points wirelessly identify a current location of each of the plurality of mobile devices
Data Source
AI summary
A mobile device is used as an access control device to gain access to a secure area of a facility. One or more wireless access points receives and an International Mobile Equipment Identity (IMEI)-based identifier that is unique to the user's mobile device, and identifies a currently location of the user's mobile device. The door is electrically unlocked when the current location of the user's mobile device is determined to be within a predetermined proximity to the door and the received IMEI based identifier of the user's mobile device is associated with a user that has access rights to access through the door. Various techniques are employed to detect possible tailgating events.
