RFLoRa Channels List: Frequency vs. Channel Number
Advertisement
LoRa operates across a variety of frequency bands, each carefully divided into channels that allow for organized and interference-free communication. Each channel is associated with a specific frequency and a channel number, both crucial for correctly configuring LoRa devices. This page provides a detailed list of LoRa channels, including a comparison of frequency vs. channel number, to help you select the optimal settings for your applications.
We’ll explore how LoRa channel frequencies impact communication range and data transmission within a LoRaWAN network. Keep in mind that different bands are defined for LoRaWAN networks in regions like the USA, EU, and China.
LoRa Channels in the 868 MHz Band
Table 1 lists the LoRa frequency channels in the 868 MHz band, which spans from 863 to 870 MHz. It shows the channel number and its corresponding channel frequency. All eight channels are separated by 0.3 MHz from their adjacent channels.
Table 1: 868 MHz band LoRa Channels
| LoRa Channel Number | LoRa Frequency |
|---|---|
| CH_10_868 | 865.20 MHz |
| CH_11_868 | 865.50 MHz |
| CH_12_868 | 865.80 MHz |
