Abstract: A system for wireless communication network is disclosed. The system includes several nodes and at least a gateway. Each of the nodes includes several first wireless network interface. Each of the first interfaces utilizes one of channels to send, receive or forward signals. Wherein the first interfaces of the same node utilize different and non-overlapping channels to send, receive or forward the signals at the same time. Each of the gateways includes a network interface and several second wireless network interfaces. The network interface connects to the Internet to receive or forward the signals. Each of the second wireless network interfaces utilizes one of the channels to receive or forward the signals. Wherein the second wireless network interfaces of the same gateway utilize different and non-overlapping channels to receive or forward the signals at the same time.

Abstract: An automatically notifying system for testing a cellular phone module is provided. The system includes a control computer having a testing program for providing a test request, a testing device electrically connected with the control computer and the cellular phone module for testing the cellular phone module in response to the test request, and sending a test status back to the control computer, such that the testing program generates a trigger signal in response to the test status, and a control module electrically connected with the control computer for sending a warning message to a communication group in response to the trigger signal.

Abstract: The present invention is an automatic testing system for a cellular phone module and a method thereof for automatically test a cellular phone module. The present invention includes a control computer having a graphic controlled program for providing a test request, wherein the graphic controlled program is written in Labview program, and a testing device electrically connected to the control computer and the cellular phone module for testing the cellular phone module in response to the testing request. The testing result is sent back to the control computer from the testing device right after the test is finished. Then the testing result is displayed via a graphic interface and stored in a text file and a graph file. The cellular phone module is determined to be good or not via the testing result.
