- What Antennas will be Used for the IoT Industry, and Which one Should I Choose?As one of the two core hardware of wireless communication (the other is the wireless module), antenna is an essential part for the application of the Internet of Things. There are many kinds of antennas to meet different frequencies, different uses, different applications and different requirements...FAQ March 14, 2022
- Application of Radio Frequency in the Internet of ThingsJust as the literal meaning of "IoT = Things + Internet", data transmission is required to connect to the Internet. The non-contact data transmission is the application scenario of radio frequency. Almost all IoT products will have RF transmission. The RF transmission with low transmit power has a short distance...FAQ September 23, 2020
- What is the Receiving Sensitivity and How does it affect the Transmission Distance?The receiving sensitivity is the minimum signal receiving power that the RF receiver can take out the useful signal correctly. The receiving sensitivity of wireless transmission is similar to people's hearing when they are communicatingFAQ August 10, 2020
- Is the Higher Antenna Gain Always the Better?We often get customer's inquiry and ask if we can provide a high gain antenna, someone even says the higher gain the better. But is that true? Is really higher gain antenna result a better effect? In fact, this view is incorrect. Simply to increase the gain, although the coverage distance is greater, the coverage will become narrower.FAQ March 04, 2021
- Is a Higher Transmission Rate Wireless Module Always the Better?Is a Higher Transmission Rate Wireless Module Always the Better? In fact, this idea is incorrect. The data level of each parameter is not equal to the performance of the module. We should select the parameters of the module according to the actual situation of the project. What suits you is the best!FAQ December 02, 2021
- What is a Fiber-glass Antenna?Fiber-glass Antenna is the most popular kind of CB antennas, which is also called as Fiberglass Antenna, FRP Antenna. They are fiberglass poles wrapped with copper vibrator and coated with protective material. They are IP67 waterproof, windproof, high temperature resistance, and corrosion resistance.FAQ July 30, 2021
