Abstract: Techniques herein facilitate dynamic configuration of a wireless local area network (WLAN) for large public venue (LPV) environments. In one example, a method may include providing an initial configuration for access points APs of a WLAN for an event at an LPV based on a profile for the event, a location of each AP for the venue, and anticipated demand at the APs; determining, for a particular time for the event, a distribution of wireless devices and channel support capabilities of the wireless devices different locations for the LPV; and providing an updated configuration for one or more APs at the one or more locations for the venue based on the distribution of the wireless devices and the channel support capabilities of the wireless devices determined for the particular time for the event at the LPV.

Abstract: A method for adaptive presence-based radio configuration of access points in a venue includes defining a number of regions in the venue in which access points are deployed, each region having a center point, and assigning a first access point to a first region, positioned at the center of the first region. The method also includes affecting a first energy level in the first region, which corresponds to a power of a transmit signal emitted by the first access point, and assigning to the first region a configurable capacity value that determines an acceptable overlap constraint between the first energy level of the first region and an energy level of a neighboring region. The method further includes generating data describing a tessellation graph in which a possible map of the access points is formed using an iterative descent process based on the first energy level and the overlap constraint.

The electronic device includes sensor circuitry for gathering or sensing data; an internal battery for powering the sensor circuitry; and an internal activation circuit for activating the sensor circuitry. The sensor circuitry may include a temperature sensor, a location sensor, a signal sensor, a sound detector, a motion sensor, or any other device that senses or gathers data. The battery may be any type of energy storage device such as a lithium or alkaline battery. The activation circuit includes a receiver for receiving a radio frequency signal from an external source and a switch for connecting the battery to the sensor circuitry in response to the receiver. The switch is operable to maintain connection of the battery to the sensor circuitry after the radio frequency signal ceases.

Abstract: Application Specific Integrated Circuit (“ASIC”) devices, such as Field Programmable Gate Arrays (“FPGAs”), may be interconnected using serial I/O connections, such as high speed multi-gigabit serial transceiver (“MGT”) connections. For example, serial I/O connections may be employed to interconnect a pair of ASICs to create a high bandwidth, low signal count connection, and in a manner so that any given pair of multiple ASIC devices on a single circuit card may communicate with each other through no more than one serial data communication link connection step. A reconfigurable hardware architecture (“RHA”) may be configured to include a communications infrastructure that uses a high-bandwidth packet router to establish standard communications protocols between multiple interfaces and/or multiple devices that may be present on a single circuit card. Dynamically-sized data packets, sized in accordance with the amount of data ready to be sent, are transferred between the devices and/or interfaces on the card.

Abstract: Communication between a multi-band RFID tag device that communicates on first and second bands with other devices may be enabled, using a bidirectional communication bridging device that converts first band signals of the RFID tag device to third band signals of another device, and vice-versa. Examples of third band-capable devices that may be bridged for communication with the first band of a RFID tag device include WiFi devices such as smart phone, notebook computer, WLAN router or any other type of WiFi enabled device. In one example, a tag interface control device may be provided in the form of a WiFi-enabled handheld unit that communicates with a multi-band RFID tag through a bridging device using NBFM radio frequency (RF) communications to retrieve or change stored data and/or change the tag operation. Such a WiFi-enabled handheld unit may be configured to be relatively small, portable, and/or battery or wireless-powered.

Abstract: A RFID tag system may be configured as a tag having a first band (e.g., multiple channel-based NBFM frequency band) transceiver to allow field programmability of tag behavior and onboard tag data. The RFID tag system may be configured to collect data from one or more local sensors through the first band link and store data points of interest in tag onboard storage. The RFID tag system may be configured to work in conjunction with a remote interrogating unit, and a handheld device or other local interrogating unit may be additionally or alternatively provided to communicate with such aRFID tag. Data that is stored on the RFID tag may be retrieved or changed, and/or the operation of the tag may be modified.
