6.3.6.2 Estimating Wireless Cable Gateway to Wireless Client Distances
The information in this section helps you to determine how far a wireless cable gateway
can be placed from wireless client devices. Environmental variances include the
capabilities of wireless clients and the types of material through which the wireless signal
must pass. When the wireless cable gateway and wireless clients reach the distance
threshold between each other, network performance degrades.
To determine wireless cable gateway placement:
1. Connect a wireless client to the wireless UBC1303AB00. Refer to
to the Network on page 16
2. Place the wireless client at around one meter (three feet) away from the
UBC1303AB00.
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.

Note 1: Different types of concrete materials are used in different parts of the world and the thickness
and coating differ depending on whether it is used in floors, interior walls, or exterior walls.
Note 2: The attenuation caused by trees varies significantly depending upon the shape and thickness
of the foliage.
