Thus, the government resolves to the administrative allocation or the state property management of the frequency.

These changes present some very challenging aspects in the utilities, including interoperability and cyber security. Nonetheless, interoperability has the highest priority between the two challenges. Operability is a key requirement in assisting vendors and utilities to solve the cyber security challenge. Interoperability has been present in arguments concerning the smart grid, but absent in the cyber security section. Interoperability is possible with almost all cyber security solutions, but only in
