What do you mean by type of station?

There are two available choices, base station or operational area. A base station is a fixed radio transceiver connected to an antenna with which mobile radios communicate. An operational area is the term we use to refer to the area within which mobile radios communicate when no base station is used.

The callsign must not be more than 12 alphanumeric characters in length and should not be a place name.
