Due to the complex nature of modern cellular technologies, it is difficult to determine which antennas do what by just looking at them alone. You need to check the schematics.

For example cellular services may use 2 or 4 MIMO ports on 3 or more frequency ranges, WiFi has 2 frequency ranges and usually 2 ports with 2 bands. A lot of the front end hardware is combined.
