20100111054 | System and method for robust data loss recovery in a wireless local area network - A system and method for robust data loss recovery in a wireless local area network is provided. The method includes splitting user data into multiple data fragments. The method further includes creating multiple beacon frames by placing each data fragment in a unique beacon frame and broadcasting the beacon frames through a wireless medium by an access point of the network. Prior to transmission, the method includes arranging the frames into a plurality of groups and creating a parity frame for each group, to be transmitted along with the beacon frame. After transmission, the beacon frames are received by a wireless client and data fragments are extracted from each beacon frame. At the receiving end, the wireless client checks whether all the transmitted beacon frames have been received. Finally, the user data is reconstructed from the extracted data fragments by reassembling the data fragments. | 05-06-2010 |

20090248529 | SYSTEM AND METHOD FOR PROVIDING VALUE ADDED SERVICES VIA WIRELESS ACCESS POINTS - A method for providing value added services to a user terminal by an access point in a wireless network is provided. The method comprises intercepting a request initiated by a user terminal for accessing information. The method further comprises determining if the request is a local search request. If the request is a local search request, then location information is appended to the request. Location specific search results are rendered on the user terminal. | 10-01-2009 |
20090257376 | INTELLIGENT ACCESS POINT FOR DELIVERING LOCATION BASED INFORMATION - A method for delivering location based information in wireless zone is disclosed. All the location based information is stored in the access point itself thus eliminating the need for backend server. Access point has the intelligence to deliver information in customized to each requesting device's display capability. To provide seamless access to local information the user will get a default web page once the device connects to access point and tries to access internet. This web page will act as a gateway to all the location based information available in the access point. Along with location based information advertisements can also be delivered to the end user in a very cost effective and targeted manner. | 10-15-2009 |
20110145642 | METHOD AND SYSTEM FOR TESTING AN APPLICATION - The present invention provides a method, test-bed and computer program product for testing an application installed on a wireless communication device. The wireless communication device communicates one or more messages wirelessly to a server through a test-bed. The test-bed is connected with the server and provides one or more testing parameters for the one or more messages. A tester, testing the application, assigns a probability to the one or more messages. Further, the tester assigns a probability to the one or more testing parameters. Thereafter, the messages are re-communicated between the server and wireless communication device through the test-bed. Subsequently, the one or more messages are identified by the test-bed and one or more wireless network conditions are emulated based on the probabilities assigned to the one or more messages and the one or more testing parameters. | 06-16-2011 |
20120236740 | NETWORK EMULATION WITH VARYING BANDWIDTH AND/OR ERROR RATE - Network emulation techniques are provided for dynamically varying network bandwidth and/or error rate. Network emulation can be performed by determining a bandwidth range, determining a plurality of specific bandwidth values distributed across the bandwidth range, and dynamically varying available bandwidth among the plurality of specific bandwidth values for a stream of network packets. Transitioning between specific bandwidth values can be performed using a probability jump matrix. Network emulation can also be performed by varying error rates, such as dropped packets, separately or in addition to dynamic bandwidth variation. | 09-20-2012 |
