CDMA Owners Information

About CDMA Technology

Code Division Multiple Access (CDMA) is a channel access method used by various radio communication technologies. CDMA is an example of multiple access, where several transmitters can send information simultaneously over a single communication channel. This allows multiple users to share the same frequency band.

CDMA is widely used in telecommunications, including mobile phone standards like cdmaOne, CDMA2000, and certain 3G and 4G wireless standards. The technology employs spread-spectrum technology and a special coding scheme to allow multiple users to be multiplexed over the same physical channel.

CDMA Patent and Licensing Information

Qualcomm Incorporated holds many of the patents for CDMA technology. Other companies also hold patents related to CDMA implementations and applications. The following table provides information about major CDMA patent holders and licensors:

Note: This information is provided for transparency purposes and may not be comprehensive. Companies and organizations using CDMA technology should conduct their own due diligence regarding patent ownership and licensing requirements.

Regulatory Information

The use of CDMA technology in telecommunications is subject to various regulatory frameworks around the world. Major regulatory bodies include:

• Federal Communications Commission (FCC) - Regulates radio frequency spectrum usage in the United States
• European Telecommunications Standards Institute (ETSI) - Produces telecommunications standards for Europe
• International Telecommunication Union (ITU) - Global standards development organization for information and communication technologies

Companies implementing CDMA technology must comply with the relevant regulatory requirements in their operating jurisdictions. This may include obtaining necessary licenses, adhering to spectrum allocation rules, and complying with technical standards.

CDMA Technology Standards

Several standards organizations maintain specifications for CDMA-based technologies:

• 3rd Generation Partnership Project (3GPP) - Maintains standards for WCDMA and evolved CDMA technologies
• 3rd Generation Partnership Project 2 (3GPP2) - Maintains standards for CDMA2000
• Telecommunications Industry Association (TIA) - Publishes standards for cdmaOne and CDMA2000

These standards ensure interoperability between different implementations of CDMA technology and provide guidelines for developers and manufacturers.
