1941 – Motorola two-way radio installed in a police cruiser.

1946 – The first commercial mobile radiotelephone service was introduced in St. Louis.

1965 – AT&T’s Improved Mobile Telephone Service (IMTS) eliminated the need for push-to-talk operation and offered automatic dialing.

1968 – The Federal Communications Commission (FCC) opened Docket 18262 to address questions regarding spectrum reallocation.

1972 – Bell Labs receives a patent for its Mobile Communications System, which describes and enables handoffs between cells.

1983 – Advanced Mobile Phone Service (AMPS) released using the 800 MHz to 900 MHz frequency band and the 30 kHz bandwidth for each channel as a fully automated mobile telephone service. AMPS is the first standardized cellular service in the world.

– Motorola introduced the DynaTAC mobile telephone unit, the first truly “mobile” radiotelephone. The phone, dubbed the “brick”, had one hour of talk time and eight hours of standby.

– October 13, 1983 – The first commercial cellular system begins operating in Chicago. In December 1983, the second system activated in the Baltimore/Washington, D.C. corridor.

1984 – The Cellular Telecommunications Industry Association was founded.

1985 – The 100th cellular system is turned on in New Bedford, Massachusetts.

1986 – The FCC switched to a lottery system to license cellular markets. At the urging of industry, the FCC allocates an additional 10 MHz of spectrum for cellular telecommunications. Cellular subscribership tops 2 million.

– 1,000 cell sites across America

1987 – Industry tops $1 billion in revenue.

1988 – CIBER Record® for carriers created, which allows nationwide wireless services

1989 – Motorola announces the MicroTAC® personal cellular phone, which uses a flip-lid mouthpiece. The phone retails for an estimated $3000.

1990s -RAM Mobile Data Network brought online. CDPD packet networks begin deployment. GSM cellular systems support circuit-switched data.

1990 – Nextel Communications, Inc. files a series of waivers with the FCC to set up low power, multiple transmitter networks in six of the top U.S. markets. Cellular subscribership surpasses 5 million.

1992 – The FCC allocates spectrum in the 2 GHz band for emerging technologies, including Personal Communications Services (PCS). The number of cellular users pass the 10 million milestone. 10,000 cell sites across America.

1992 – World’s first commercial text message sent by employees of Logica CMG.

1993 – Bell Labs develops the DSP1616 chip, a digital signal processor used in millions of handsets.

1994 – iDEN network technology, a packet-data network that integrates paging, data communications, voice dispatch and cellular capabilities, is unveiled.

1996 – Bell Atlantic Mobile launches the first commercial CDMA network in the United States.

– The Telecommunications Act of 1996 becomes law, in part designed to open other communications markets to competition. 38 million cell phones in use in the U.S.

1997 – Subscribership in the wireless industry—cellular, PCS and ESMR—surpasses 50 million.

– Industry benchmark reached: 100,000 direct carrier employment

– 50,000 cell sites across America

– Delivery of digital wireless data and voice networks (2G)

1998 – The average consumer used his or her phone for 122 minutes per month.

– Ericsson, Motorola, Nokia and Unwired Planet create WAP Forum.

– WAP 1.0 specifications published on the web.

1999 – Congress passes Wireless Communications and Public Safety Act.

2000 – Wireless subscribership in America exceeds 100 million.

– Digital wireless users outnumber analog subscribers

– Nearly 1 million Americans directly or indirectly employed by wireless. (Jobs in the wireless industry pay wages that are approximately 78 percent higher than the national average.)

– The Cellular Telecommunications Industry Association™ merges with the Wireless Data Forum to become the Cellular Telecommunications & Internet Association™

– Camera phones introduced in Japanese market.

2001 – The average wireless consumer uses his or her phone for 320 minutes per month.

– November 8, FCC votes to raise CMRS spectrum limits for individual carriers from 45 MHz to 55 MHz, and subsequently eliminate cap in January 2003.

2002 – FCC awards 90 MHz of additional spectrum for advanced wireless services.

– Delivery of digital wireless data and voice enhanced networks (2.5G)

– October 13, 2003 – 20th Anniversary of Commercial Wireless Communications.

2004 – Subscribership reaches over 180 million.

– The Celluar Telecommunications & Internet Association™ changes it name to CTIA-The Wireless Association™

Today Wireless Serves America

  • More than 196 million Americans are wireless subscribers.
  • More than 225,000 direct service provider employees
  • 200,000 times each day, someone uses a wireless phone to call for help.
