6.5 Radio Path Testing

To carry out a radio path test, you will need two WI-I/O 9-x modules. One module will be
"fixed" and the other "mobile". Both units will need power supplies and antennas. The power
supply for the mobile unit is normally a 12V battery, but make sure that the battery is fully
charged - batteries with low voltage will lead to low radio power which will affect the test
result.
The object of the test is to determine whether radio paths are reliable, marginal or unreliable. A
reliable path will have a margin of at least 10dB above the background noise level in good
weather - this margin is enough to ensure that the radio path remains reliable in poor conditions.
A marginal path will work reliably in good conditions, however will fail during poor conditions.
If the test is carried out during rainy or foggy weather, then a margin of only 5dB is required.
