Abstract :
An experimental 150 MC personal signaling system has been set up in New York City to evaluate over-all technical performance and explore subscriber reactions to the system. The system includes pocket receivers equipped with tuned reeds and central office arrangements adapted for direct customer dialing. The paper describes the system in over-all terms, and tells how it was engineered. It also compares this system with present 35 MC systems and discusses traffic and radio transmission problems.
