The wireless communications industry is fast growing and historically strong with new technologies mixing with traditional ideas. Because of this, it’s more important than ever to team with one of Allcomm Technologies expert guides. Traditionally, Motorola Solutions products and designs have been the defacto standard but that hasn’t precluded other manufacturers from presenting alternatives. At best, this can move the industry forward, at worst, it leads to confusion and disparate, incompatible products. The introduction of digital product ideas could have been such an issue. Luckily, user organizations like the Association of Public Safety Communications Officers (APCO) and the European Technological Standards Institute (ETSI) are now upholding and testing to standards. Of course, that means there are two digital standards and traditional analog. Below is a quick overview of the differences:
Analog radio has been around since the 1930s. It’s simple, easy and interoperable. All radio communications is governed by the FCC and requires company licensing. Most vendors adhere to the Motorola squelch codes commonly called Private Line codes and in the 1970s the digital squelch codes called Digital Private Line. The radio is still analog though. Analog radios sound the closest to direct human voice but as the signal has to travel farther, noise is introduced. In other words, the further the signal travels the worse it sounds. At the end of it’s reach, the voice is overwhelmed by the noise. Repeaters are a tool to extend the reach of communications by using a strategically located antenna and radio. Our experts can guide you in repeater technology and site requirements. Analog radio may be the right alternative for your organization for a number of reasons including price and interoperable communications.
MotoTRBO (ETSI DMR)
MotoTRBO is based on the ETSI digital standard. Unlike analog radio, digital radio includes error correction and eliminates the noise that plagues analog communications. It doesn’t change the distance a signal can travel, it just makes it sound perfect over the whole distance. The ETSI standard MotoTRBO is a perfect fit for most organizations. The MotoTRBO product includes great sounding voice, text, GPS and other data. The system can even be encrypted for privacy and safety. MotoTRBO can include repeaters for coverage and a single repeater can give anywhere from 2 to 4 voice channels. Grouping multiple repeaters can increase channels dramatically. The MotoTRBO systems can be linked over computer networks for greater coverage. Our experts will work with you and your IT department to configure the system to meet your specific needs. One of the great features of MotoTRBO is the open architecture apps being introduced every day. There are apps for interfacing computer, smartphones and data products. No other technology offers such a large and diverse portfolio. MotoTRBO systems are installed throughout the world and are the fastest growing wireless communications systems in the USA.
APCO Project 25 (P25)
Project 25 of APCO defines the government interoperable digital standard. As a digital standard, P25 includes error correction for perfect sounding communications. The P25 standard requires backward compatibility with analog radios as well as compatibility between encrypted and unencrypted radios. This means that the radio will listen to anyone on the same frequency whether in analog, P25 or P25 encrypted. That’s total interoperability. P25 is a US government requirement when applying for grants. P25 is less open to apps but is strict in it’s deployment to assure communications. Our communications experts are trained to deploy and design to these requirements. There is a second phase of APCO P25 being deployed that doubles the capacity of today’s systems. Most states, counties and towns are moving to this digital standard. Motorola Solutions P25 products are designed to a public safety standard and some even meet the firefighter delta T requirements. This means that the P25 products are the most robust in the world. If a rugged, interoperable system is your need, we can guide you through a P25 design and deployment.
