RTX8200 LOCATION GATEWAY GUIDE 4.6 16 | P a g e
Proprietary and Confidential
TX Mode - Transmitter mode:
In transmitter mode, it is the RTX8200 Location Gateway that is the active beacon transmitter, and the receiver will be
responsible for conveying the location data to a central point. This can be useful when you know all employees are
carrying a phone that supports BTLE beacons. It also allows for a more stringent power setting and thus more precise
tracking. However, the receiver sensitivity and antenna on the phones will play a large part in the measurement
uncertainty. Another benefit of the TX mode is the long battery lifetime.
Use case: Door installation:
For the door installation use case, RTX recommends two positions. Next to the door and just above the door, as shown
on the illustration below. It should be noted that position 1 will be more reliable, since the tracked object will need to
be further in the room for position 2 to detect the presence. The door opening in this case is 90 cm wide and 210 cm
tall.
Position 1 - Gateway Settings
In this example, the beamforming will be configured to steer left into the door
opening and the attenuation is set to -30 dB for detection only in the door.
Position 2 - Gateway Settings
In this example, the beamforming will be configured the center setting and the
attenuation is set to -16 dB for reliable detection after tracked object has walked
through the door. In this case the object needs to travel a meter inside the room.
