Wireless Device on page 15 if needed.
2. Place the wireless client at around one meter (three feet) away from the UBC1301-
AA00.
3. Obtain the RSSI value for the connected client. This value is used in the formula
further below.
4. Use the following table to determine what materials the wireless signal must travel
through to reach the desired wireless coverage distance.
5. Use the following table to determine what materials the wireless signal must travel
through to reach the desired wireless coverage distance.
6. Use the attenuation value from the materials table above in the following formula:
Formula:
(Transmit Power, use -30dBm) – (Receiver Sensitivity, use RSSI value) =
Allowable Free Space Loss
Allowable Free Space Loss ÷ Materials Attenuation Value =
Optimal Distance in Feet Between the UBC1301-AA00 and a Wireless Client
