Mifi Antenna's

I was looking at the MiFi board and the antenna connectors caught my attention.

I count 4 antenna connectors. Does this mean that it also needs 4 antenna’s? (3 for the 4G and 1 for WiFi)

And what type antenne is needed here? What length / power rating?

 

They are for WiFi, 4G/3G, GPS, etc.

The one on the main board is for Wifi, others are on the 3G/4G module, which is really depends on the datasheet of the module.
