Si4455-2WayLink-DEMO
2.3. Frequency and Frequency Bands
The RFstick provides RF matching solutions for all supported frequency bands. Different HW solutions are required
for each frequency bands. Range test demo automatically reads required frequency band information from the on
board EEPROM and selects the appropriate frequency range.
Silicon Labs provides Si4455 Two Way Demo Link Kits for the following frequency bands:
Range test demo provides four different selectable frequencies in all the supported bands. In case of custom
parameters are stored the custom frequency can also be selected, but only in the defined frequency band. Table 2
lists the available frequencies.
2.3.1. Node Address
Each node using the range test demo can select from 16 different addresses (0-15). Transmitter and receiver of the
same link have to use the same addresses. It is advised to use only one link (one transmitter and one receiver)
with the same address within close proximity, otherwise the different systems will disturb each other.
2.3.2. Modulation
User can select from three types of modulation:
2.3.3. Data Rate
User can select from three different data rates. In case of custom settings are stored the custom data rate can also
be selected. Table 3 lists the available data rates.
