TIA-102

TIA-102 is a suite of standards developed by the Telecommunications Industry Association (TIA) relating to digital radio communications, particularly for public safety and private land mobile radio (LMR) applications. It defines specifications for the Project 25 (P25) digital radio system, which is a widely used standard in North America and other regions for interoperable radio communications among public safety agencies.

The TIA-102 standards address various aspects of P25 systems, including:

• Air Interface: Defining the modulation, encoding, and protocol for over-the-air transmission and reception.
• Interoperability: Ensuring that radios from different manufacturers can communicate with each other.
• Security: Specifying encryption methods for secure communication.
• Vocoder: Defining the voice coding algorithm used to digitize and compress speech.
• Data Transmission: Enabling the transmission of data alongside voice.
• Trunking: Providing a method for dynamically allocating radio channels to users.

The TIA-102 series of standards is essential for the development, implementation, and maintenance of P25 radio systems. It allows public safety agencies and other organizations to communicate reliably and securely, even in challenging environments. The standard is continuously updated and revised to incorporate new technologies and address evolving needs. Different parts of the TIA-102 standard address different aspects of the P25 protocol.
