How Does it work

The tags use a unique feature of Bluetooth Low Energy which detects other BLE devices in the area.

When people come within six feet of each other for a period of time

  • The device makes an audible chirp
  • A record of the contact is made on the tag and uploaded to the AiRISTA software system.
  • Triggers for tag distances and event duration are configurable over the air.

Tags communicate with the software platform using existing Wi-Fi systems, employees’ smart phones, or small gateways provided by AiRISTA.

The system can integrate securely with government databases and third-party applications.

AiRISTA - What Customers Are Saying

Veterans Affairs

“The health of our veterans is first and foremost. We needed a way to help keep participants socially distant and quickly do contact tracing in the event of a positive test. This solution helps provide a common standard of care across all our populations.”

David Tostenrude, Director of National Wheelchair Games

National Indemnity Co.

“I’m proud to work for a company where our CEO sees the value in keeping people safe.”

The social distancing feature helps people maintain six feat of separation with an alert from a wearable tag. Tags automatically identify to each other when they come near. Contact tracing records the history of these contacts in a database. The tags relay their contacts to the cloud software platform over existing wireless networks. 

Yes, the tags can be purchased and used only as alerts for social distancing. Contact tracing requires use of the software platform. The software platform also provides reports to monitor trends and evaluate the effectiveness of various policies and workflows.

BLE tags are low cost and offer long battery life. BLE+Wi-Fi tags are badge-style tags and require recharging  every couple months (depending on tag configuration). AiRISTA Flow also offers an application that makes your smart phone act like a tag. 

To speed deployment and keep costs down, an existing Wi-Fi network is typically used to communicate to the cloud based software platform. The BLE+Wi-Fi tags communicate directly with Wi-Fi access points. BLE tags can communicate with access points that support BLE.

Older infrastructure that does not support BLE can use the AiRISTA Flow BLE/Wi-Fi Gateway – a small device that plugs into an AC outlet. AiRISTA Flow also makes available an app for smart phones and tablets that provide communication to the software platform through Wi-Fi or the cellular connection. 

Once contacts are uploaded to the portal, the portal returns an acknowledgement to the tag ensuring contacts are not missed.

Only the tag’s ID is stored in the cloud database. Any association of a user with a tag is under the control of the administrator. Data is retained for 30 days by default, then purged. Moreover, the software platform complies with General Data Protection Regulations (GDPR) protecting the use and retention of personal information.

Yes, tag location is collected and made available via a table in the cloud portal. A location “snapshot” is made each time the tag uploads its contacts to the cloud software via an access point or gateway – the unique ID the access point or gateway and the time is recorded. The system administrator associates that access point or gateway with a physical location in the building like break room, lobby, etc.

The AiRISTA Flow implementation of BLE provides not only beaconing of an outbound signal, but it also scans (listens) for other BLE devices. The stronger the signal received from another tag, the closer the tag. Once the dB threshold representing six feet is met, we alert the individual and record the ID of the other tag. 

The AiRISTA Flow tags can be configured over the air. For example, if safe distancing recommendations change, the tags can be remotely configured to the new distance settings. 

Phone apps represent a challenge since antenna designs are unique and dB levels differ at six feet. AiRISTA Flow uses patented technology to normalize the effect across mobile phone vendors. 

RF signals are effected when passing through water, and because our bodies are 60% water, they impede the signal. However, AiRISTA Flow has several patents that account for body position and interference. Although the result is not perfect, the impact is reduced. When considering body position, a tag worn on the wrist will ben less impeded than a tag worn on the chest for example.

For Social Distancing only, tags can also be purchased separately from the software platform. If Contact Tracing in addition to Social Distancing is desired, the purchase of a tag includes use of the AiRISTA Flow software platform for one year. Subsequent years can be purchased at a discount.
