Patent number: 9596585Abstract: A first wireless devices establishes an association with a second wireless device by sending a connection request packet to a previously-discovered second wireless device. The second wireless device identifies the received packet as a connection request and responds with a connection response packet, thereby establishing an association between the first and second wireless devices. The wireless devices can then, for example, send and receive data.Type: GrantFiled: September 29, 2006Date of Patent: March 14, 2017Assignee: Microsoft Technology Licensing, LLCInventors: Abhishek Abhishek, Hui Shen, Jiandong Ruan

Patent number: 9503957Abstract: A wireless device that utilizes a single network interface to simultaneously connect to an infrastructure network and a mesh network. The device has a driver layer with a media access control module for each network type. A multiplexing module and transceiver module within the driver can direct received information associated with one of the networks to an appropriate media access control and then to an appropriate network adapter. For transmitted data, the multiplexing module can receive data from the application layer through an appropriate network adapter and route it to an appropriate media access control module for processing. The processed data can be interleaved by the transceiver for transmission.Type: GrantFiled: October 13, 2015Date of Patent: November 22, 2016Assignee: Microsoft Technology Licensing, LLCInventors: Alok Manchanda, Taroon Mandhana, Jiandong Ruan, Saurabh Mahajan, Alireza Dabagh, Thomas W Kuehnel

Patent number: 9265088Abstract: A software based wireless infrastructure system is provided. The system has a driver that communicates with the network stack and a network interface card (NIC), a station server in communication with the station driver and an 802.1X supplicant or an 802.1X authenticator. Each NIC provides station and/or access point functionality support. The driver drops packets that have been received if the packet has not been authenticated and associated. Packets that have been fragmented or encrypted are unfragmented and decrypted. An association manager is used in conjunction with a configuration table manager to associate stations and access points via management packets. A manager receives 802.1X data packets from the packet processor and sends them up to a station server that communicates with user mode applications and an 802.1X supplicant or an 802.1X authenticator that are used to authenticate and deauthenticate stations and access points. APIs are provided to enable communication between the components.Type: GrantFiled: November 28, 2012Date of Patent: February 16, 2016Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Abhishek Abhishek, Arun Ayyagari, Hui Shen, Krishna Ganugapati, Jiandong Ruan

Patent number: 8478300Abstract: Discovery of services between devices is provided prior to establishing a connection between devices, including wireless-enabled devices or devices that are communicatively coupled to wireless access points or other wireless communication devices. Discovering services prior to establishing a connection may facilitate finding a desired service. The services that may be discovered may be, for example, print services, camera services, PDA services or any other suitable services. Services may be discovered using 802.11, UWB or any other suitable wireless technology. As one example, particular services may be requested. As another example, services that are provided by a device may be advertised.Type: GrantFiled: December 20, 2005Date of Patent: July 2, 2013Assignee: Microsoft CorporationInventors: Thomas W.

Method and apparatus for managing scanning in wireless computing devices to reduce power consumption
Patent number: 8102798Abstract: A method and system for scanning in a wireless device having a wireless network interface card (NIC) is presented. The system has a scanning history table for storing scanning results and a scanning engine that adjusts the scanning period based upon a history of scanning results and commands the NIC to scan for available networks after the period has expired. The engine receives scan results from the NIC, stores the scan results in the scanning history table, determines a scanning period based upon a history of scan results, sets the scanning period, and commands the NIC to scan for available networks after the scanning period has expired. The engine is programmed to set the scanning period using an exponential function and to reset the scanning period to a default period if the scan results are different from a prior scan result or if a triggering event is received.Type: GrantFiled: August 7, 2007Date of Patent: January 24, 2012Assignee: Microsoft CorporationInventors: Anton W.

Patent number: 8102813Abstract: Systems and methods for handling a transition of a roaming mobile user device (i.e., a roaming client) from one access point (AP) to a target AP, referred to herein as soft inter-AP handoff. This technique involves a second mobile user device that is already connected with the target AP, called a roaming coordinator, assisting in handoff coordination between the APs. This coordination includes assisting the roaming client in establishing a client-to-client connection to relay data traffic during the handoff, while the roaming client establishes a connection with the target AP using traditional techniques. Soft inter-AP handoff allows a faster hand-off between APs than traditional techniques, and may reduce jitter in communications with the roaming device during the transition.Type: GrantFiled: April 28, 2006Date of Patent: January 24, 2012Assignee: Microsoft CorporationInventors: Abhishek Abhishek, Yue Chen, Hui Shen, Jiandong Ruan, Taroon Mandhana, Yi Lu
