All ProTAACS wireless gateways can support up to 100 sensors. To
expand a network beyond 100 sensors, simply add another wireless gateway
to the network.
Yes. You may expand your network as needed, up to 100 sensors per
wireless gateway. You can add an unlimited number of wireless gateways,
so you are not limited to the amount of wireless sensors you can have on
ProTAACS's wireless sensor networks currently operate on the ISM 900MHz
(902-928MHz) band as well as 868MHz, 433MHz and 920 MHz radio bands.
ProTAACS's X-SERIES wireless products use ProTAACS’s new Encrypt-RF bank level security, featuring a 256-bit exchange to establish a global unique key, and an AES-128 CTR for all data messages. So security is maintained at all communication points from sensor to gateway, gateway to software, and back again. Learn more about ProTAACS's Encrypt-RF here.
ProTAACS's standard wireless products use several features to help protect sensor data in transit. Our proprietary sensor protocol uses very low transmit power and requires specialized radio equipment to operate. Typical wireless devices that operate on non-proprietary communication protocols (Wi-Fi, Bluetooth, Zigbee) operate using different frequency bands so they can't be used to eavesdrop on the radio communications from the ProTAACS family of sensors. In addition we use a robust packet tampering evaluation routine to ensure that traffic wasn't altered between the sensors and the gateways. This enables us to check for well-formed data packets that only originated from ProTAACS enabled devices. To further protect data we have algorithms that protect against spoofing and re-transmission of wireless data packets. This is included with the best in class range and power consumption protocol developed for ProTAACS wireless sensor systems.
The life span of the battery is dependent on a number of factors: whether you are using ProTAACS standard sensors or our newer X-SERIES sensors, how frequently the sensor transmits data (heartbeat), how far the sensor is from the wireless gateway and obstructions that could cause difficulty in sending data (farther distance and obstructions require that the radio to operate at longer intervals to send and receive data).
