2. Wireless Performance Parameters:

The LoRaWAN international standard supports various center frequencies, including 433MHz, 470MHz, 868MHz, and 923MHz. Please rearrange the provided information to generate a highly similar content.

Frequency modulation and spread spectrum modulation are two types of modulation technology. Linear frequency modulation involves changing the frequency of a carrier signal in a linear manner over time. Spread spectrum modulation, on the other hand, spreads the signal over a wider frequency band for increased security and resistance to interference. These modulation techniques play a crucial role in various communication systems, ensuring efficient and reliable data transmission.
