Particular embodiments of a wireless communication system comprise a wireless device and a base station having at least one network connection and an RF transceiver. A mobile station 9-2 and a femto base station 5-1 located within a macrocell 6 and a microcell 7 receive the HCS priority level of the macrocell 6 and the microcell 7 from a macro base station 3 or a micro base station 4. The current flow path is remote from the gate dielectric layer to avoid damaging the gate dielectric by a large current, so as to improve the dielectric strength of the electrostatic discharge protection circuit.
