4G antenna and WiFi antenna work in different frequency bands. Although their working principles and frequency ranges are similar to a certain extent, their characteristics and uses are very different.

1、 Band selection

The 4G antenna mainly works in the LTE band, and its frequency is mainly between 1.7 and 2.6 GHz. The specific frequency depends on the specific mobile equipment and network standards. The WiFi antenna mainly operates in the 2.4GHz and 5GHz frequency bands, which are the main frequency bands of the WiFi network.

2、 Antenna gain

The gain of 4G antenna is generally about 20 dbi, while the gain of WiFi antenna is relatively small, generally about 10 dbi. The gain directly affects the signal strength and coverage of the antenna.

3、 Antenna size

The size of 4G antenna is generally larger, because it needs to cover a wider frequency range and greater signal strength. The size of WiFi antenna is relatively small, because its operating frequency and signal strength are relatively small.

4、 Antenna type

The 4G antenna usually adopts the MIMO antenna technology, which can simultaneously receive and transmit multiple signals, thus improving the transmission rate and stability of signals. WiFi antenna usually adopts single antenna technology, which can only receive and send one signal.

5、 Antenna directivity

The directivity of 4G antenna is generally strong, because it needs to cover a wider range and better signal strength. The directivity of WiFi antenna is relatively weak, because its signal strength and coverage are relatively small.

6、 Antenna connector

4G antennas usually use SMA or N-type connectors, while WiFi antennas usually use SMA or TNC connectors. Different connectors will affect the installation and connection of antenna.

7、 Antenna application

4G antenna is mainly used for mobile communication devices, such as mobile phones, tablets, etc. It can improve the transmission rate and stability of signals, so as to provide better mobile communication services. The WiFi antenna is mainly used for WiFi network devices, such as routers, APs, etc. It can improve the transmission rate and stability of signals, so as to provide better WiFi network services.

To sum up, although 4G antenna and WiFi antenna have similar working principles and frequency ranges to a certain extent, their characteristics and uses are very different. In practical applications, it is necessary to select the appropriate antenna according to the specific needs and environment.
