Forty-five days after the publication of this Plan, new systems in areas of high congestion, subject to local conditions, shall meet the one vc per kHz efficiency standard or equivalent of Phase 1 spectrum efficiency criteria. In certain circumstances, new systems that make use of equipment not meeting the spectrum efficiency criteria may be authorized. For example, a new system that optimizes the use of the existing spectrum environment through vertical loading may be permitted. Such systems would be considered as any other non-standard system as per the calendar of events. Furthermore, applications for the expansion of an existing network or system employing non-spectrum.
