List of Standards

ANSI J-STD-008, Personal Station - Base Station Compatibility Standard for Dual-Mode Wideband Spread Spectrum PCS System.

Formal definition of the PCS (1900 MHz) air interface. The PCS standard differs from IS-95-A primarily in the frequency plan and in call processing related to subscriber station identity, such as paging and call origination. The basic signal structure (message formats, coding, and modulation) are identical

TIA/EIA/IS-95-A, Mobile Station - Base Station Compatibility Standard for Dual-Mode Wideband Spread Spectrum Cellular System.

Formal definition of the cellular (800 MHz) CDMA air interface . IS-95-A differs only slightly from the prior version, IS-95.

IEEE Standard 269-1992, IEEE Standard Method for Measuring Transmission Performance of Analog and Digital Telephone Sets (ANSI)
