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.
