1. Frequency

Different frequency bands are applicable to different countries. Domestic wireless modules are 433MHz, 868MHz and 2.4GHz, while foreign wireless modules are mostly 315MHz and 915MHz. Choose the right frequency band to avoid abnormal communication.

2. Distance

Different products need different distance, wireless modules companies such as smart home, need good penetration, distance hundreds of wireless modules; unmanned remote control aircraft, need transmission distance, power wireless modules.

3. Look at the power consumption

Some products need high power consumption, long transmission distance; and some products need low power consumption, low power consumption; so be sure to ask when buying wireless modules power consumption, receiving current, output current and other specific parameters.

4. Look at the antenna

Wireless network module is divided into PCB antenna and an external antenna, external antenna is divided into several kinds, communication distance, that day the line must choose the right antenna system can be better directional and extend the communication distance.

5. Look at the price

Choose wireless module is the time to consider its cost performance, do not desire cheap and choose their own products, loss but their own, you can buy samples to choose after the field test.

6. Look at the size

When choosing a wireless module, consider the size of the wireless module, whether it can be embedded in the device, otherwise, the wireless module itself is suitable and can not be used white collar.

7. Reputation

The better the reputation of the manufacturer, the better the quality of the product. Should ask the manufacturer whether there is after-sales service, a good after-sales service is very good for us, if the manufacturer does not have after-sales service, should be carefully considered.
