LoRa versus FSK modulation signal spectrum
LoRa modulation is a wireless communication technique designed for long-range, low-power data transmission. It is based on Chirp Spread Spectrum (CSS) modulation, which spreads the signal over a wide frequency range, making it robust against interference and noise. This technology is particularly useful for Internet of Things (IoT) applications, where devices need to communicate over…

Testing 868MHz LoRa range, part 1: urban area
With a (more less) free evening I decided to finally start testing range of 868MHz LoRa E45-TTL-100 radio modules I described only yesterday. Instead of building new testing rig, I only upgraded testing setup I used to test range of FS1000A and XY-MK-5V 433MHz radio modules. Few hours later I came up with this: I’ve…
