Troubleshooting
Performing a range test will give an initial indication of the expected performance. If the loopback test indicates
that additional range may be required, ask the following questions about the installation:
Do I have clear RF line-of-sight?
If the Fresnel Zone is not clear of the ground or other obstructions, often the best way to improve range is to
raise the antennas higher off the ground to help transmit over vegetation or other obstacles.
What frequency am I using?
The Wireless Petro-Net Modem
®
comes in two varieties: 900 MHz and 2.4 GHz. The 900 MHz waves penetrate
objects and travel better than their 2.4 GHz counterparts. If you are in the U.S., Canada, Australia or Israel, you
are using the 900-MHz radios. The 2.4-GHz radios must be used in European countries and where the ETSI
standard is required.
Can I use a directional antenna?
Directional antennas will have better gain than the omni-directional antennas. While the omni-directional-gain
antennas can improve performance in line-of-sight applications, the performance in non-line-of-sight situations
is very similar to a dipole. If you need to maximize range, using a gain antenna may be the best solution.
