Comparison of three common 2.4 GHz transmitter and receiver module

The application market of 2.4 GHz transmitter and receiver module in the field of Internet of Things is very extensive, and its advantages and disadvantages are also very obvious, but it cannot stop its popularity. Recently, many customers have asked us how to choose products when purchasing 2.4 GHz transmitter and receiver modules.

NiceRF: A detailed comparison of three common 2.4 GHz transmitter and receiver modules

2.4 GHz transmitter and receiver module LoRa128X

LoRa128X is a long-distance 2.4GHz high-performance IoT wireless module. It is a related series of products developed by our company based on Semtech's high-performance RF chip SX1280/SX1281. The 2.4 GHz transmitter and receiver module LoRa128X uses LoRa modulation and has extremely high receiving sensitivity. The modules of the SX1280 chip series integrate the "time of flight" function, which can realize the function of wireless ranging.

2.4 GHz wireless module RF2401

RF2401 is a long-distance, low-power, high-sensitivity FSK wireless module designed for working in the 2.4G ISM global application-free frequency band. The module adopts the wireless chip designed by the top RF company in Europe, which has the characteristics of low cost, small size and stable product. Maximum transmit power of 10dBm, receive current of 7mA and receive sensitivity of -115dBm. After testing, the maximum distance can reach 300m, far exceeding the 2.4 GHz wireless module of the same type, and can be widely used in daily life and activities where wireless connection is required.

2.4 GHz transmitter and receiver module RF2401PRO

The RF2401PRO adopts the nRF24L01+ device of NORDIC Company, which is a highly integrated 2.4G wireless ISM band wireless transceiver chip. The biggest advantage of the 2.4 GHz transmitter and receiver module RF2401PRO is that it can transmit voice and pictures, but it also sacrifices its transmission distance, and its transmission distance is only 70m.

Difference between the three 2.4 GHz transmitter and receiver modules

Summarize:

1. None of the three 2.4 GHz transmitter and receiver modules can communicate with each other.

2. Wireless transmission speed: RF2401PRO>RF2401>LoRa128X.

3. Open distance: RF2401PRO<rf2401<lora128x.< p="">

In fact, seeing this, everyone should know how to choose a 2.4 GHz transmitter and receiver module. If it is more demanding in terms of distance, we can choose the wireless module of the LoRa128X series. If you have lower requirements in terms of distance, you can choose RF2401, which can help the project save a lot of costs. If you need voice or picture transmission, you can choose RF2401PRO.
