20080232338 | METHODS AND APPARATUS FOR SECURE, PORTABLE, WIRELESS AND MULTI-HOP DATA NETWORKING - A mobile network solution provides secure and portable wireless networking service to mobile users with devices equipped with wireless network interfaces. The Secure Nomadic Wireless Network, or SNOWNET, follows a hierarchical approach. Special SNOWNET nodes are deployed in the area where networking service is needed and form a backbone network. At the same time, SNOWNET nodes provide local access service to regular mobile clients. SNOWNET provides security through authentication of the nodes and clients, as well as through encryption of the data. | 09-25-2008 |
20080316988 | METHOD FOR FAST ROAMING IN A WIRELESS NETWORK - A roaming service method for a fast and secure wireless network is provided. In an embodiment of the present invention, an AP, which an STA associates with, transmits proactive keys needed for roaming to neighbor APs of the AP. When the STA moves to one of the neighbor APs, a reassociation is carried out between the STA and the neighbor AP using the already provided proactive key. In another embodiment of the present invention, an authentication server transmits proactive keys needed for roaming to neighbor APs to which the STA is likely to move, so that when the STA moves to one of the neighbor APs, a reassociation is carried out between the STA and the neighbor AP using the already provided proactive key. | 12-25-2008 |

20100098138 | Method And Apparatus For Improving Energy Efficiency Of Mobile Devices Through Energy Profiling Based Rate Adaptation - Improved battery life for mobile wireless devices communicating using standard network protocols is obtained by measuring an energy profile of the transmitter circuitry with respect to transmission rate and transmission energy and adjusting operating conditions according to measured or deduced error rates. Additional energy savings are obtained reducing the total number of bits transmitted using payload compression and header truncation making use of application layer communications between the remote device and a power-unconstrained proxy device. | 04-22-2010 |

20100080183 | System And Method For Interference Mitigation In Wireless Networks - A computer-implemented method for scheduling a packet for transmission in a wireless local area network can be used to account for hidden and/or exposed terminals. The method includes determining whether the packet is to be transmitted to a computing device through a wireless access point that is in conflict with at least one other computing device associated with a different access point. The method further includes determining whether there is a conflicting packet scheduled to be transmitted for any conflicting computing devices associated with a different access points and scheduling the packet for transmission based on any conflicting packets. The method yet further includes forwarding the packet to a wireless access point at the scheduled time. | 04-01-2010 |

20100020776 | Wireless network-based location approximation - The invention pertains to location approximation of devices, e.g., wireless access points and client devices in a wireless network. Location estimates may be obtained by observation/analysis of packets transmitted or received by the access point. For instance, data rate information associated with a packet is used to approximate the distance between a client device and the access point. This may be coupled with known positioning information to arrive at an approximate location for the access point. Confidence information and metrics about whether a device is an access point and the location of that device may also be determined. Accuracy of the location determination may be affected by factors including propagation and environmental factors, transmit power, antenna gain and diversity, etc. A location information database of access points may employ measurements from various devices over time. Such information may identify the location of client devices and provide location-based services to them. | 01-28-2010 |
20100067546 | Method And Apparatus To Vary The Transmission Bit Rate Within Individual Wireless Packets Through Multi-Rate Packetization - A transceiver for wireless data transmission provides for variable bit rates within a packet (intra-packet rate changes) to provide a high-speed adaptation to variations in link quality useful for continuous mobility applications. Intra-packet rate variations may be obtained with standard hardware by remapping payload data to a subset of the hardware transmission constellation symbols. | 03-18-2010 |

20080259883 | Method and System for Client-Driven Channel Management in Wireless Communication Networks - A method and system for assigning channels to a plurality of access points (APs) of a wireless communication network is disclosed. The method includes obtaining first information regarding first interference experienced by a first client due to multiple APs being positioned in proximity of that client, and obtaining second information regarding second interference experienced by either the first client or a first of the APs with respect to which the first client is associated, where the second interference is due either to others of the APs that are in proximity to the first AP, or to others of the clients that are in proximity to either the first client or the first AP. Additionally, the method further includes determining channel assignments for the plurality of APs based upon each of the first and second information. | 10-23-2008 |

20150163633 | Crowdsourced Signal Propagation Model - According to an embodiment, a method of estimating a distance to a wireless access point in an indoor environment using a signal propagation model begins with the receipt of a first received signal strength value based on a signal received at a first device from a wireless access point in the indoor environment. Based on a predetermined characteristic of the indoor environment, an estimate is made that the received signal originated from a first distance from the first device. A signal propagation characteristic is estimated based on the first signal strength and the estimated first distance and a plurality of signal samples are received from a plurality of devices. Finally, a signal propagation model for the indoor environment is created based on the signal propagation characteristic and the signal samples, and a distance to any wireless access point in the indoor environment is estimated based on the signal propagation model. | 06-11-2015 |
