A legal opinion provided to a National Assembly member finds that the government may lawfully require 5G infrastructure investment as a condition for reallocating 3G and LTE spectrum. The review says spectrum reassignment is a discretionary and beneficial administrative act, allowing conditions. It states that LTE frequencies remain essential for 5G quality in NSA environments and that investment obligations match legislation on service quality standards. It also says investment options tied to reassignment fees are possible if obligations remain proportionate.
