Radio Telephone

Radio Telephone

  • "The system operators were companies licensed to provide mobile telephone carriers, much like the cellular carriers of today. In most major cities, serviced was provided by the local Bell Telephone Company, and a few private companies, sometimes called radio common carriers (or RCCs). Customers had the choice of selecting the carrier that provided the service they needed. However, the service was expensive, and the quality of the connection was poor."

  • From The Cellular Telephone Installation Handbook, by Michael Losse, Quantam Publishing, 1988.
