Routers generally have built-in antennas and external antennas
The built-in antenna is a combination of the device and the antenna. The antenna is inside the device. The appearance of such device is generally smaller, but it will affect the reception of the signal to some extent.

External antenna: the equipment is separated from the antenna, and the equipment is composed of host, signal line and power line. Because the signal line is external, the equipment can be placed in a more open place, so the signal and stability will be much better, and the accuracy will also be better.
