A method includes generating, at a server, an event policy for controlling one or more wireless beacon devices in a network; detecting an event in the network; determining whether the event matches the event policy; when the event matches the event policy, generating programming information for configuring the one or more wireless beacon devices; and forwarding the programming information via one or more wireless access points to the one or more wireless beacon devices for configuring the one or more wireless beacon devices based on the programming information.

Event-driven policy based management of wireless beacon and tag devices

In accordance with one aspect, presented herein is a method to encrypt beacon device telemetry broadcast packets while respecting the low power and low processing requirements inherent to wireless beacon devices and various other challenges which such an encryption scheme brings. In accordance with another aspect, a methodology is provided through which the network can identify if an unauthorized connection is being established with a beacon device and thereby prevent potential beacon device tampering.

Enabling secure beacon telemetry broadcasts based on battery power state of a beacon device

Steering for location-assisted inter-set roaming, between different networks of the same or different types is provided by: identifying a first station connected to a first wireless network in an environment; identifying a direction of travel of the first station; identifying a second wireless network and a third wireless network as candidate roaming targets, based on the second wireless network and the third wireless network neighboring the first wireless network in the direction of travel, wherein the second wireless network and the third wireless network are different from the first wireless network; modifying a neighbor list for the first station to include an Access Point (AP) included in the third wireless network based on environmental knowledge; removing APs included in the second wireless network based on the environmental knowledge; and transmitting the neighbor list to the first station.

Location-assisted inter-set roaming

In one embodiment, a device in a network receives a radio frequency (RF) beacon. The device determines a received signal strength indication (RSSI) of the received RF beacon. The device compares the determined RSSI to an RSSI threshold. The device sends a burst of ultrasound or infrared beacons when the determined RSSI of the RF beacon exceeds the RSSI threshold. The burst of ultrasound or infrared beacons is then used by a location service in the network to determine a physical location of the device.

Infrastructure enabled smart dual-mode tags

An emergency caller location system uses enterprise Wireless Local Area Network (WLAN) location systems to provide more accurate location information on an emergency caller. A cellular telephone modifies its WLAN identifier, such as its Media Access Control (MAC) address, in response to a user initiating an emergency call. The MAC address is modified based on an identifier known to the cellular network, such as the phone number, subscriber name, International Mobile Equipment Identifier (IMEI), International Mobile Subscriber Identifier (IMSI), and/or International Circuit Card Identifier (ICCID). The cellular telephone may additionally modify the probe timer of the WLAN interface to enhance the ability of the WLAN location system to determine the location of the device.

Mobile device wireless identifier assignment for emergency calls

In one embodiment, a method includes creating at a network device, a user session with an interactive digital sign, generating a session tag for the user session, wherein the session tag is configured for input at a mobile device, transmitting the session tag to the interactive digital sign, and continuing at the network device, the user session with the mobile device. An apparatus and logic are also disclosed herein.

Transfer of session from interactive digital sign to mobile device

Techniques are presented to enable a network element in a network to receive a request from an application on a device, the request being encapsulated in a packet that includes a header that contains a physical layer identifier of the device to which the application does not have access. The physical layer identifier at the network element may be obtained. A response may be sent to the application on the device, the response containing at least one of the physical layer identifier of the device and location information of the device.

Enabling mobile applications to acquire a MAC address for obtaining location information

In an example embodiment, a wireless device is configured to associate with a first access point on a first frequency. The wireless device listens for a predefined frame, which may be sent by neighboring access points or other wireless devices. When the wireless device receives a signal comprising a predefined frame, the wireless device acquires a parameter, such as signal strength, for the signal. The wireless device sends the parameter for the signal to the first access point.
