  • Patent number: 12348417
    Abstract: Stateless network address privacy may be provided. A data packing may be received with an obfuscated destination address and an un-obfuscated source address. An un-obfuscated destination address may be determined based on the obfuscated destination address. An obfuscated source address may be determined based on the un-obfuscated source address. The obfuscated destination address may be replaced with the un-obfuscated destination address and the un-obfuscated source address may be replaced with the obfuscated source address. The packet may be forwarded.

  • Publication number: 20250106808
    Abstract: Described herein are devices, systems, methods, and processes for determining the geo-positions of access points (APs) in a wireless network. The techniques involve utilizing geo-positioning data including global navigation satellite system (GNSS) measurements, wireless local area network (WLAN) signal measurements, air pressure measurements, preexisting knowledge, or any combination thereof. The GNSS measurements may include pseudo range measurements. The WLAN signal measurements can include time of arrival (ToA), channel state information (CSI), and/or received signal strength indicator (RSSI) measurements. The geo-position of each AP is calculated by applying Bayes' theorem to all available geo-positioning data and selecting the geo-position hypothesis with the highest probability. The geo-positions of the APs can be updated when a new measurement is obtained. The techniques can handle diverse AP deployments including heterogeneous APs with varying sensor capabilities.

  • Publication number: 20250071180
    Abstract: Profile-based association method for enterprise networks may be provided. A computing device may configure a first profile and a second profile. Next, the client device may be configured with a set of network profiles associated with a plurality of networks. A user of the client device may be queried for a profile choice for one of the plurality of networks. Then the client device may associate with the one of the plurality of networks according to the profile choice provide by the user.

  • Patent number: 7296152
    Abstract: A method for authenticating an end user in a network environment is provided that includes positioning an identification element in a first device that is operable to provide an interface for an end user. The first device is further operable to communicate with an internet protocol (IP) network and with a second device. The end user is then authenticated with a selected one of the first and second devices through the IP network using the identification element such that the end user may operate the first and second devices in multiple access networks that cooperate to provide connectivity to the end user. Each of the access networks is operable to facilitate communications between the end user and the IP network.
