Use case: Room installation:
If the user wants to detect presence in a small room or office RTX
recommends installing this in the top corner of a room. The power
level should be adjusted according to the size of the room. We have
provided a table with different room sizes and power settings. The
Antenna direction should be set to “center” in all the cases. This is
with the beacon in TX mode. The values given is measured inside a
fully equipped office space, it is very likely that the user will have to
tweak the values to fit their exact needs.

Use case: Hallway installation:
In a hallway installation, it will be possible to track if equipment or personnel
has moved past certain point in the hallway. Hallway installations can be
challenging, since there often will a lot of reflections in the RF propagation.
This can be omitted by adjusting the power accordingly. However, this will
also change the effective range of the beacon. The following values have
been tested in a concrete hallway with a width of 3 meters. The beam
steering has been set to center for optimal performance

External antenna
In high security areas it might be a requirement, that the active device is hidden above the ceiling or behind a wall,
such that it cannot be tampered with. In this scenario the external antenna version of RTX8200 can be used.
Obviously, the setup will be a bit more cumbersome, since RF cables are needed. The installation will also be highly
dependent on what kind of antenna is used, however this also adds some flexibility to control the radiation pattern.
The following use case will be based on a standard 2.4 GHz Dipole antenna. This creates an omnidirectional antenna if
installed vertically, or a weakly directional antenna if placed horizontally.
