This invention discloses a new system and method to generate real-time layout of wireless access points for mobile users based on multiple-device collaboration. Wireless receiver collects signal identifier, strength, encryption, network type(telecom operator) nearby. Mobile device broadcasts a request to other devices nearby via short-range wireless communication protocol like ZigBee. This request is forwarded or responded by other devices. Each request has a fixed hop to avoid request passed too far away. Besides, each request has a direction to avoid duplicate request and correct direction from mobile users. When a mobile device walks across a wireless signal, it gets the signal attributes, detects signal strength and stores the some locations which has the same signal strength. When there is a new request coming, the signal attributes and one or two pairs of location and signal strength is packaged into the response content. After requester gets all response messages nearby, it can calculate and render wireless access point layout map around it.

Rendering real-time layout and signal strength of nearby WIFI access points

  Mobile device has wireless receiver to detect wireless access point information such as identifier, signal strength, encryption type and etc. When mobile device owner moves across a wireless signal, it detects and stores some special locations (such as GPS) with the corresponding signal strength for a short period.

  After it receives a wireless signal layout request from broadcast around, the device can ignore, answer or forward this request. Request contains max hop and clock direction. This device will validate if it lays on the right clock direction based on the relative position of requester then decide to take any action or not.

Besides, it will check the left hop in current request then decide to forward it or not. In the meanwhile it respond this request with what it knows.

  Request consists of request type (fixed characters), requester location, request network type (telecom operators), requester machine ID, signal direction. "Signal direction" is used to prevent request broadcasting backward. Signal direction consists of two clock directions. Signal direction is calculated based on the mobile user's movement direction.

The response message includes WIFI ID, type, one or several group of composite signal information (signal strength, location).

1)Locate accurate position of each wireless access point

2)Mobile device can get the wireless access point which is out of detectable range...
