The Telecommunications Industry Association (TIA), which develops Project 25 (P25) and other communications standards, issued four calls for interest from its TR-8 committees. The first two are in regard to the TR 8.18 Committee’s new project for wireless communications systems — performance in noise and interference limited situations, and the second two are in response to the TR 8.5 Committee’s project for mobile data peripheral interface and port number assignments.
The TR-8.18 Engineering Committee on Wireless Systems Compatibility – Interference and Coverage issued a call for interest for document TSB-88.1-E, initially titled “Wireless Communications Systems – Performance in Noise and Interference Limited Situations Part 1: Recommended Methods for Technology-Independent Narrowband Performance Modeling.”
The same committee also issued a call for interest for document TSB-88.3-E, initially titled “Wireless Communications Systems – Performance in Noise and Interference-Limited Situations Part 3: Recommended Methods for Technology-Independent Narrowband Performance Verification.”
The stakeholders for the first two calls may include, but are not limited to private LMR, P25, Land Mobile Communications Council (LMCC) and the National Coordination Committee (NCC).
The TIA TR-8.5 Engineering Committee on Signaling and Data Transmission issued a call for interest for document American National Standards Institute (ANSI)/TIA-102.BAEG-A, initially titled “Mobile Data Peripheral Interface.” The interface specifies the protocols used on the interface between the subscriber unit and the mobile data peripheral.
Finally, the same committee issued a call for interest for document TIA-102.BAJD-A, initially titled “TCP/UDP Port Number Assignments.” The specification assigns transmission control protocol (TCP)/user datagram protocol (UDP) port numbers to TIA-102 data applications and reserves a range of the Internet Assigned Numbers Authority (IANA) dynamic/private port numbers for assignment to future TIA-102 data applications.
