Performance Indicators for Purchasing Wireless Transceiver Modules

At present, there are many types of wireless transceiver modules on the market, with varying quality. Among the thousands of modules, it is not an easy task to choose the right one. When purchasing a wireless transceiver module, the main focus is on the following parameters and performance indicators. You may wish to refer to it to help you choose a suitable wireless transceiver module.

When purchasing, the performance indicators of the wireless transceiver module are mainly considered: receiving sensitivity, frequency, power, power consumption, etc.

Receiving Sensitivity

With the continuous development of the Internet of Things, the application of wireless transceiver modules has become more and more extensive, and the industry's requirements for module sensitivity are getting higher and higher. The wireless front-end transceiver module is as high as -121dBm, which meets the standard. In addition, it should be noted that there is a certain relationship between receiving sensitivity and transmission distance. The higher the sensitivity, the longer the transmission distance. The ultra-high receiving sensitivity can be used on occasions that require long-distance transmission and extremely high reliability.

Frequency

In different projects in different countries, the frequency used may be different, and it is necessary to match the transceiver module with the appropriate frequency according to the actual situation of the project. Generally, the frequency range of the front-end wireless transceiver module can be 433/470/868/915MHz, and the frequency within the frequency range can also be customized.

The Power of the Module

The output power of the module has a greater impact on the transmission distance. The greater the power, the longer the communication distance. Those with some experience in this industry should know that the farther the module is, the greater the power and the larger the volume. Therefore, you can't just consider power and distance, but consider whether the size of the module can be embedded in the device.

The Power Consumption of the Module

The power consumption of the module includes: receiving current, transmitting current, sleep current. Low power consumption and long-distance are generally not available at the same time. However, the LoRa module, which has been rapidly developed in the past two years, can achieve ultra-long-distance transmission with low power consumption. In addition, low-power modules are suitable for use in projects that require battery power.

Purchasing a wireless transceiver module mainly focuses on performance indicators such as receiving sensitivity, frequency, power, power consumption, working voltage, and working temperature. Of course, factors such as size, distance, cost, etc. should also be considered.
