Why are LoRa modules so expensive?

The LoRa module is the hottest wireless module in the IoT, but its expensive cost also discourages many people. Do you know why the LoRa module is so expensive? Where is its value?

First of all, NiceRF will briefly introduce the LoRa module: LoRa is an ultra-long-distance wireless transmission solution based on spread spectrum technology developed by Semtech in the United States. It is currently one of the most representative communication technologies in low-power wide-area networks. The LoRa modules we see on the market are all developed based on Semtech's LoRa chip.

Next, NiceRF will specifically talk about why the LoRa module is so expensive:

1. Transmission distance of LoRa module

The transmission distance is one of the most important parameters to measure the wireless module. The LoRa module has a much longer transmission distance than other wireless modules under the same power.

2. Power consumption of LoRa module

Power consumption is also one of the important parameters for measuring wireless modules. The lower the power consumption, the longer the project duration. The LoRa module is undoubtedly very good in terms of low power consumption, and while taking into account low power consumption, it can also ensure the ultra-long-distance transmission of the module. This is also one of the reasons why the LoRa module is so popular on the market, but the low transmission rate of the LoRa module is also its drawback to ensure the transmission distance.

3. Sensitivity of LoRa module

The LoRa modulation technology of the LoRa module performs a unique spread spectrum function on the signal. Under the same data rate condition, its spread spectrum modulation method can obtain a sensitivity of 8-10dBm higher than the traditional GFSK, FSK and other modulation methods.

4. Anti-interference ability of LoRa module

The LoRa modulation mode is adopted by the LoRa module. This modulation mode has excellent spread spectrum modulation and forward error correction technology, and can even distinguish and extract data from noise; compared with traditional FSK, GFSK and other modulation modes, it has a Stronger anti-interference ability.

The performance of the LoRa module: transmission distance, power consumption, sensitivity, anti-interference ability and other aspects are top-notch. So, this is why it is so expensive.
