AirFinder Quick Start Guide
1. AirFinder System Overview
AirFinder Staff Alert Devices work with the AirFinder Precise Location Service, resulting in the AirFinder Staff Alert System.
The AirFinder Precise Location Service consists of the following hardware components:
AirFinder Location Beacon (LB) or Location Beacons (LBs) AirFinder Access Point (AP) or Access Points (APs) (also referred
to as Aggregators) AirFinder Gateway (GW) or Gateways (GWs)
Location Beacons (LBs) provide the input data for the AirFinder Precise Location Service.
Location Beacons rapidly broadcast short Bluetooth Low Energy (BLE) data packets on the three Bluetooth Advertising channels (2.402 GHz, 2.426 GHz, and 2.480 GHz); these broadcast packets are called beacon messages. These BLE beacon messages are transmitted multiple times per second, and the on-air time of each beacon is very short - measured in milliseconds.
AirFinder Staff Alert Devices, when in Active Alert Mode, scan for Location Beacon advertisement messages, calculate their location, connect to an Access Point, and transmit that location. See Staff Alert Event - BLE Only below for more details.
AirFinder Access Points (or, in Marriott parlance, BLE Aggregators) propagate the local BLE network for AirFinder Devices. AirFinder Access Points (APs) are installed at hotels or other facilities in a configuration to provide complete and redundant BLE network coverage for Devices. APs, like Location Beacons, broadcast a frequent and periodic beacon message; however, the AP beacon message is different than the Location Beacon message. These AP beacons are also heard by AirFinder Devices, but not used by Devices in the standard location algorithm. The AP beacon message indicates to a Device that A. it is an Access Point, and B. whether the AP is available for connection, so the Device can transmit its location, or whether the AP is currently busy with traffic from other Devices, and, instead, the Device should connect to another AP. A Device will default to connecting to the AP whose beacon RSSI is highest, unless that AP is busy; in that case, the Device will connect to the AP with the next highest beacon RSSI and so forth. As installed in the AirFinder Staff Alert System, in almost all cases, Devices will be receive beacon messages from multiple APs in any location within a hotel.
When an AP receives an Alert Location from a Staff Alert Device, the AP prioritizes these messages over any other and immediately transmits this message to an AirFinder Gateway. APs use an FCC-certified overthe-air-protocol called Symphony LinkTM, which operates in the 902-928 MHz frequency band, to communicate with Gateways. Link Labs is the
4
AirFinder Quick Start Guide
creator of the Symphony Link Protocol and the AirFinder Gateways.
Like APs, Gateways are installed at a hotel or other site to provide comprehensive and redundant Symphony Link coverage. This Symphony Link Network is an Internet of Things (IoT) network service layer for all Access Points. Access Points communicate Alert messages to Gateways. When a Gateway receives an Alert message from an Access Point, it acknowledges to the Access Point that the message was received.
Access Points have several other functions, in addition to aggregating location messages from Staff Alert Devices. Location Beacons also periodically connect to Access Points to send a heartbeat (i.e. "still alive") message. This short heartbeat message contains the LB MAC ID and also the current voltage of the batteries of the LB. Access Points also regularly send their own heartbeat message to Gateways, indicating that the Access Point is connected and functioning properly. Staff Alert Devices also transmit a heartbeat message periodically.
If, or when, the configuration of Location Beacons or Staff Alert Devices need to be changed, the configuration change will be transmitted from the AirFinder Precise Location Service Platform through a Gateway down to the Access Points. In non-Alert, normal functioning, when Location Beacons and Staff Alert Devices connect to Access Points when transmitting their heartbeat message, they also check a mailbox to determine if there are new configuration settings to download. If there are, then the LB or Device, updates its settings.
AirFinder Gateways aggregate and transmit all Staff Alert messages, as well as any other traffic from Devices, Location Beacons, and Access Points to the AirFinder Precise Location Service cloud platform. These messages are also directed to the AT&T backend. Gateways are connected to the Internet via an AT&T IoT (LTE) network connection. In some rare cases, the Gateway may have an Internet connection via a LAN or other backhaul method.
Any messages to Staff Alert Devices or other infrastructure coming from either the AT&T Platform or the AirFinder Platform are transmitted via that cloud to the on-site Gateways. Gateways then pass on the messages, as required by each message type, to individual hardware or categories of hardware.
Staff Alert Event
In the event that an individual holding an AirFinder Staff Alert Device presses and holds both of the Device's buttons, then the Device goes into Active Alert Mode. The Device will emit a tone (65 dB) when placed into Active Alert Mode. When the Device is in Active Alert Mode, the Device immediately, and then every five seconds until it the Active Alert Mode is deactivated,
5
AirFinder Quick Start Guide
scans the BLE advertising channels for BLE advertisement messages from Location Beacons.
0. The Devices record the MAC ID and Received Signal Strength Indicator (RSSI) of all received (or "heard") Location Beacon advertisement messages during the scan interval.
1. These RSSI values are processed by the Device's location algorithm. The algorithm also uses any historical location determinations to determine the current location.
2. The output of the algorithm is the LB in closest proximity to the Device.
Note: AirFinder device locations are based on highest probability of proximity to a specific location beacon - not exact/precise location. The precision of this proximity determination is a function of the number of location beacons, their placement, and any other data going into the calculation. For example, future versions of the AirFinder Precise Location Service will also use ultrasound.
3. When the Device has determined the LB it is in closest proximity to, it will attempt to initiate a connection to the AP on its list that has the highest RSSI beacon message value and is available. In the event of a successful connection, the Device will receive an acknowledgement message from the Access Point. 1. If the Device does not receive an acknowledgement, it will resend the message, either to the first AP or another AP.
4. At the next scan interval, the Device will repeat Steps 1-3. If the Device determines that it is in the same location as the previous message, it will go back to sleep until the next scan interval.
5. If the Device, on repeating Steps 1-3. determines that it is in closest proximity to a different Location Beacon from the previous scan window, then the Device will proceed to Step 4.
Note: a condition that could cause a Device to determine a new location would be when a person holding a Staff Alert Device is moving between rooms or down a hallway.
