Step 2

Placing the transmitter

The operating range essentially depends on how many obstacles there are

between the transmitter and the receiver. Therefore, it should be carefully

considered where to place the transmitter.

Below, two examples are given. In the first example, there are 4 walls

between the transmitter and the receiver. The transmission may be

interrupted. By locating the transmitter such as in the second example,

reliable transmission to all of the 6 rooms is possible.

Also, the elevation of the transmitter as well as the presence of reflecting

walls will influence the range.

It is suggested to experiment in order to find the best location for the

transmitter.

Example 1: Poorly chosen

transmitter location

Example 2: Improved

transmitter location
