The Telecommunications Industry Association (TIA) develops telecommunications standards for use in the United States, and in any other countries that care to adopt them or at least allow their use. The TIA spun off from the EIA (Electronics Industry Alliance) in 1988 and is ANSI accredited. Current, published TIA documents are available for purchase from tiaonline.org.
Cellular Networking Perspectives focuses mainly on the TR-45 standard for cellular and PCS systems, but it often refers to the activities of other standards committees. The Technical Review (TR) committees established by the TIA are:
