When developing or testing applications for deployment in ETSI regions, it is encouraged to select specific channels to transmit on rather than using the reader default.
NOTE: This only applies to readers conforming to the ETSI regulations. It is not permitted within the FCC regulations to select specific channels. Therefore, this post is not relevant to FCC readers.
Testing with ItemTest
When using ItemTest, you can select specific channels in the reader configuration dialog, as shown in the screenshots below:
1. Launch ItemTest, go to "Reader Settings" menu, click "Configure" button next to the ETSI reader, and in "Frequency Settings (ETSI Only)" section, select "Use Specified Frequencies" checkbox.
Note: "Frequency Settings (ETSI Only)" section appears only when you connect to an ETSI reader.
2. Select desired channels.
When testing with ItemTest, it’s always best to use the method described above (Selecting “Use Specified Frequencies” checkbox and selecting the desired channels). Even if there is only one reader in the system design or vicinity of the system, “Use Specified Frequencies” checkbox should be checked and all channels should be selected; see ETSI Lower Band Channel Selection Guide.
When developing applications, transmit channels can also be selected using the Octane SDK. Using the simple lines of code below, you can select the necessary transmit channels:
// Specify the transmit frequencies to use. // Make sure your reader supports frequency hopping and // ensure the frequencies are valid for your region. // The following example is for ETSI (Europe) // readers. List freqList = new List(); freqList.Add(865.7);
freqList.Add(866.3); freqList.Add(866.9); freqList.Add(867.5); settings.TxFrequenciesInMhz = freqList;
This example can be found as part of the Octane SDK (example is called "SetTxFrequencies") and should be used along with these “best practice” tips when developing applications for the ETSI region.
