Friends who are familiar with the wireless transmission industry know that wireless bridges are transmission devices used to transmit audio, video, and data signals. The signals generated by wireless bridges must be transmitted through antennas, which means that wireless bridges must be used in conjunction with antennas. There are two common types of wireless bridges, one is external and the other is internal. Here are the differences between internal and external antennas:

The built-in antenna is small in size and easy to install due to its integration with the device. However, built-in antennas are generally used in short-range wireless transmission systems because the gain of built-in antennas is generally small, and the transmission distance is definitely close.

At the same time, as the transmission distance stretches and extends, if the distance exceeds ten kilometers or more, the transmission angle and reception angle of the wireless bridge device will vary from tens of degrees to several degrees with the distance. The antenna gain degrees are 24dbi, 29dbi, 32dbi, and 34dBi. The wireless bridge uses external devices, and antennas with different gain degrees collect data signals in a bowl shape. The more concentrated the collection, the longer the transmission distance.
