WHITEPAPERS

This document describes interoperability of numerous existing LMR technologies to broadband PTT.

The paper compares and contrasts emerging wireless bearers for mission critical SCADA.

This Whitepaper written by Hughes, documents lessons learned after being one of the first organizations on the ground providing communications support in Texas, Puerto Rico and US Virgin Islands following one of the worst hurricane seasons on record.

This white paper uses statistical data provided through extensive lab testing and through the use of actual recorded digital radio RF transmitter parameters. It shows how modulation alignments of one radio’s transmitter parameters can positively or negatively affect performance of another radio’s receiver.

Hytera offers an ideal, cost-effective solution to system operators that need an accelerated migration to advanced DMR technology – eXtended Pseudo Trunk (XPT).

This white paper gives the background to the development of the DMR Interoperability Process by the DMR Association, explains the value of the process to users and manufacturers and will help users and potential users of DMR systems get value from the Association’s work to establish formal interoperability testing

This white paper examines the two leading digital modulation technologies that are capable of achieving this doubling of spectral ef ciency: 6.25 khz FDMA and two-slot 12.5 khz TDMA. Businesses looking to migrate to the most ef cient professional digital systems to achieve greater capacity and performance will need to choose one or the other — FDMA and TDMA are not interoperable.

The White Paper - 5 Questions to Ask Before You Implement a Dispatch Solution with DMR, also includes a worksheet which you can use to aid discussion with Omnitronics or your chosen radio manufacturer/s.

This paper provides technical information on currently available open standard, digital technologies. For organizations seeking to replace existing networks, or considering an initial purchase of a communication solution using land mobile radio (LMR), this paper will seek to inform those decisions.

This short paper sets out the requirements of the DMR standard and technical characteristics of DMR radios which enable smooth migration from, and co-existence with, analogue from the perspective of European (CEPT) and North American regulatory requirements.

A clarification from the DMR association about DMR Tier III - August 2011

Jonathan Bunce of Simoco Group looks at the future for TETRA and considers the benefits of DMR in a changing landscape for critical communications, where voice, data and business process come together.

This white paper gives the background to the development of the DMR Interoperability Process by the DMR Association, explains the value of the process to users and manufacturers and will help users and potential users of DMR sytems get value from the Assiciation's work to establish formal interoperability testing.
