An American company, Cellular 21, Inc. (later to become Advanced Cordless Technologies, Inc.) headed by broadcaster Matt Edwards, petitioned the FCC to permit the use of CT2 technology in the US. ACT built two active test systems which were located in Monticello, NY (outdoor), and outside and inside the South Street Seaport complex in lower Manhattan. The Monticello public field trials used Timex technology which was incompatible with the trans-European standard, while the South Street Seaport indoor test used equipment from Ferranti, GPT, and Motorola, which at the time manufactured CT2 equipment for the Singapore and Hong Kong markets. GPT and Motorola both provided CT2 equipment for the Rabbit system rollout (GPT handset and charger shown above). All the testing was under an FCC Experimental license. The ACT/Cellular 21 "Petition for Rulemaking" (RM-7152), along with a later petition by Millicom, became the basis of the FCC's PCS initiative (FCC GEN Docket 90-314) which resulted in the allocation of frequencies in the 1.7 to 2.1 GHz band as spectrum expansion for the crowded 800 MHz cellular band. The FCC used the acronym PCS to designate Personal Communications Services, separate and distinct from cellular service which was 800 MHz analog at the time. PCS was to be digital-only, and has progressed through several "generations" (mostly marketing designations) such as G3 and G4.
