The difference between lora and wifi how transmit data

The difference between LoRa and wifi

 LoRa and WiFi are two different wireless communication technologies, and the main differences are as follows:

1. Range: LoRa can realize long-distance communication, the coverage can reach several kilometers to tens of kilometers, while WiFi coverage is usually only between tens of meters to a few hundred meters.

2. Power consumption: LoRa has low power consumption, which can realize low power wide area wireless network (LPWAN), usually about 1W (or 0.1W). WiFi is relatively more power consumption, up to about 30W.

3. Security: LoRa has some security protocols specifically developed for the Internet of Things, giving it security advantages. The security for WiFi relies more on encryption protocols and requires other security measures to ensure network security.

4. Data transmission rate: LoRa has a low rate, up to 50 Kbps. The rate of WiFi is typically between 100Mbps and 1 Gbps. Therefore, WiFi may be more suitable in applications that transmit large amounts of data or require high-speed transmission.5. Cost: The price of LoRa chips is relatively low, usually between several dollars and tens of dollars. WiFi chips are more expensive, typically between a few dollars and hundreds of dollars. This also means that LoRa may be more appropriate in some scenarios that are cost-sensitive or require large-scale application.

How does the lora transfer the data

 LoRa is a low-power, long-distance wireless communication technology that can be used for communication between IoT devices. The process of data transfer includes the following steps:

1. Data collection: to obtain the data required to be transmitted through sensors or other equipment.

2. Data coding: convert the collected data into binary data through coding.

3. Data encryption: Data can be encrypted to improve security.

4. LoRa modulation: the encoded data is modulated to represent different values of digital signals through different frequencies and timing, so that it can be transmitted on the wireless communication channel.

5. Signal transmission: use the LoRa module to transmit the modulated signal to the receiving end.

6. LoRa demodulation: The LoRa module at the receiver demodulates the received signal to restore the digital signal.

7. Decoding and decryption: the demodulated data is decoding and converted into original data, and decrypted to restore the original data.8. Data storage: store the restored data for subsequent processing or application.

The difference between lora transparent transmission and fixed-point transmission

 The difference between Lora (Long Distance Internet of Things) transparent transmission and fixed-point transmission is that:

1. Transparent transmission: Lola transparent transmission refers to the way that the communication data is not changed or resolved during the communication process. The Lora Transparent Transport transfers the raw data to the target node without any processing of the data. Therefore, in transparent transmission, it is necessary to determine the data format and data structure of the sender and receiver, and to ensure that the data is not changed or destroyed during transmission.2. Fixed point transmission: Lora fixed point transmission refers to the transfer of data to a specified node or location. In a fixed-point transmission, the data has an identifiable address or a target node, so that the Lora transmission system can accurately transmit the data to the target location.This transmission mode is suitable for scenarios where information needs to be sent to specific devices or locations, such as remote control, alarm systems, etc. In conclusion, Lora transparent transmission and fixed-point transmission have different functions and application scenarios. Transparent transmission is for scenarios where raw data needs to be transmitted, while point transmission is for scenarios where data needs to be accurately transmitted to a specified device or location.
