Ingress Protection rating (or just IP rating), is an international standard (IEC 60529) used to rate the degree of protection or sealing effectiveness in electrical enclosures against intrusion of objects, water, dust or accidental contact. It corresponds to the European standard EN 60529.
Operating frequency is the frequency at which the communications are being made with the total bandwidth occupied by the carrier signal with modulation. Usually bandwidth of the antenna will be wider than the bandwidth of the signal so that more than one center frequency the antenna can be put in to effective use.
That power available at a specified output of a device under specified conditions of operation.
