Ultra Wideband (UWB) is a type of RFID technology that uses an extremely low power level and a 6.6 GHz transmitting frequency to provide tag information for location-based solutions. A UWB real-time location system (RTLS) can track thousands of tags precisely in a large area like a warehouse, or a single tag in a small coverage zone like a doorway

Yes - UWB technology is extremely safe because of the very low transmit power level of the tag. A UWB tag transmits at a power level that is 10,000 times less than a regular cell phone.

No - UWB transmits at such a low power level and across such a wide frequency range that it does not affect other wireless technologies such as Wi-Fi, Bluetooth, UHF, or handheld passive readers. Tests have shown that the interference impact on UWB from a wireless technology like Wi-Fi is essentially negligible.

Yes - UWB's security is enhanced by its very low transmit power, and the data about the tagged item being transmitted. Tag transmissions over the air are secure because the tag signals are at such a low power level that they are impossible to distinguish from RF energy generated by other devices. The tag data generated by the Readers is strictly tag identification. The item level association occurs with an entry on a database secured in the user's IT infrastructure.

In a precision mode application, typical tag location data accuracy can range from 12-36 inches (sub-meter to 1 meter), depending on factors such as RF environment, reader density, tag orientation, etc.

Up to 8,000 tag locations per second can be computed and provided to higher level application software by the PinPoint system (using 1 Hz tags and minimum recommended hardware platform).

Yes - each tag transmission packet includes the battery status of the tag and is available to higher level application software through the Location Software API. The actual sending of the alert would be completed by higher level application software.

No - Ultra Wideband (UWB) RFID poses no security or compatibility risk to Wi-Fi networks because the UWB tags are not Wi-Fi client devices (as are PDAs, laptops, etc.) and are never associated with an access point. Also, Time Domain's UWB technology operates at 6.5 GHz, which is outside the Wi-Fi frequency range.

A tag location is computed each time the tag sends a packet update (e.g. 1 Hz, 4 Hz, etc.)
