In relation to ADS-B compliance, why must I switch to 1090ES above FL 180?

According to the FAA's Final Ruling, all aircraft operating in the designated airspace FL180 and above, would need to transmit ADS-B utilizing the 1090ES band. Aircraft that operate below FL180, have the option to equip with a 978 UAT solution or a 1090ES solution.
