TA7-G3Wi-Fi/BLE Gateway

G3 Wi-Fi / BLE Wi-Fi / BLE Gateway Copyright © 2018 AiRISTA Flow, Inc. All rights reserved. a i r i s t a f l o w . c o m The G3 gateway is a small AC powered device suitable for North American power outlets and many electrical outlet types for other countries using a plug adapter. It provides a low-cost method to communicate BLE information over Wi-Fi networks. BLE tags are convenient for their long battery life and low cost. But when a Wi-Fi network is used to exchange tag information, BLE-only tags require a dual BLE / Wi-Fi gateway to facilitate the communication. Small, cost effective device allows BLE tags to communicate over Wi-Fi networks The AiRISTA Flow G3 gateway uses an integrated eyelet to screw to the wall plate to deter theft. And the tactile button allows for user defined actions when necessary. The G3 gateway is small and deploys quickly. It can be used at choke points like doorways as BLE tags move past. And they can be used in hotel rooms or along production lines to create an umbrella of communication coverage. Companies want to maximize the investment in their Wi- Fi deployments. But until the access points support an integral BLE radio, the G3 will be the gateway between BLE networks and Wi-Fi networks. Wi-Fi / BLE Gateway Provides Wi-Fi Network Access for BLE Tags •BLE 5.0 compliant •Over the Air programmability •Omni-directional antenna •On/Off switch •Theft deterrent eyelet securely attaches to electrical face plate •Temperature and Humidity Sensor Benefits Features •Leverage the investment in Wi-Fi networks when deploying BLE tags •Low cost •Fast to deploy •Support for popular BLE protocols •Ideal for conference rooms, break areas, choke points, etc. •Can be configured and monitored remotely •Provides two-way communication with Airista Flow BLE Tags The AiRISTA Flow G3 gateway provides Wi-Fi network access for BLE tags. The low cost and long battery life of BLE tags make them desirable, but to exchange data over Wi-Fi networks they need a gateway device between BLE networks and Wi-Fi networks. This facilitates use cases like choke point detection, telemetry exchange and proximity detection for social distancing. G3 has a built in temperature and humidity sensor.
