closest permitted channel that matches the specified value, which is based on the lower channel limit plus
an integer multiple of the quantization value. Each region has a quantization value based on regulatory
specifications. The following table provides the channel setting limits for each region setting.
When manually setting frequencies, the module will round down for any value that is not an even multiple of
the supported frequency quantization. For example, in the NA3 region, setting a frequency of 917,599 kHz
results in a setting of 917,500 kHz.
When setting the frequency of the module, any frequencies outside of the valid range for the specified
region are rejected.
Frequency Hop Table
The frequency hop table determines the frequencies used by the ThingMagic Nano when transmitting. The
hop table characteristics are:
• Contains up to 62 entries.
• Must be within the frequency range for the region currently selected.
• Changes are not stored in flash, thus changes made are not retained after a power cycle, including when
the ENABLE line is activated after having been in the shutdown state.
• Inability to change individual entries after uploading without reloading the entire table.
• Frequencies are used in the order of entries in the table, so if a random order is required, the frequencies
must be pre-randomized before entering.
If necessary for a region, the hop table are randomized to create a pseudo-random sequence of
frequencies to use. This is done automatically using the default hop tables provided for each region.
