What are the differences between GPS antenna and GSM antenna?

GPS antenna is a type of navigation antenna that receives satellite signals for positioning or navigation; The satellite signal is divided into L1 and L2, with frequencies of 1575.42MHz and 1228MHz, respectively. L1 is an open civilian signal, and the signal is circularly polarized. The signal strength is around 166-DBM, which is a relatively weak signal. Its components include: ceramic antenna, low noise signal module, cable, and connector. Nowadays, the application of in car GPS antennas is becoming more and more widespread, but some car explosion-proof films can affect the GPS antenna signal, so an external antenna with a magnet (which can be attached to the roof) is often necessary for in car GPS.
GSM antenna is a digital mobile phone system widely used in Europe and other parts of the world. The GSM antenna uses a variant of Time Division Multiple Access, and it is currently the most widely used among the three digital wireless telephone skills. It includes several frequency bands such as GSM900: 900MHz, GSM1800: 1800MHz, and GSM1900: 1900MHz; GSM antenna can digitize materials and compress data, and then send it out of the channel together with the other two user data streams, each with its own time slot. Because many GSM antenna network operators have roaming protocols with other foreign operators, users can still continue to use their mobile phones when they go to other countries.
The interfaces on the GPS antenna and GSM antenna are also different. The interface of the GPS antenna needs to match the external antenna interface of the navigation instrument or GPS Bluetooth satellite module; The GSM handheld antenna is usually connected to your mobile phone through Bluetooth in the car phone hands-free system. When selecting an external antenna, it should match the external antenna interface of your car phone hands-free system.
