It works much closer to the Shannon theoretical limit and breaks the traditional implementation limit of FSK narrow band systems. The data rate ranges from 2<1 kbps to 250 kbps to 1 Mbps, while the sensitivity varies from -150 dBm to -100 dBm to -90 dBm to -125 dBm depending on the data rate and bandwidth. This allows Lora to demodulate below the noise floor and achieve better sensitivity than traditional systems. In conclusion, Lora offers significant advantages in terms of data rate, sensitivity, and the ability to operate closer to the Shannon theoretical limit. Its spread spectrum modulation scheme allows for improved performance in noisy and crowded RF environments, making it a compelling choice for wireless communication applications. Overall, Lora's unique combination of features positions it as a leading technology for modern wireless networks.
