FIVE REASONS TO MIGRATE TO DIGITAL TWO-WAY RADIOS

In the beginning, there was analog technology, which uses frequency modulation (FM) to produce a continuous wave with the voice signal. An analog two-way radio works as both transmitter and receiver, with that continuous wave in between. Analog has been the primary technology platform since the initial development of wireless communications.

Analog radios have been used for business applications as far back as 1933.

  • Analog Advantages: The integration of such a simple system into a single computer

chip has dramatically reduced the cost of analog radios.

  • Analog Disadvantages: The analog radio system has many functional limitations, and

the technology has been around so long that the scope of possible innovations is virtually exhausted.

ALONG COMES DIGITAL

Digital two-way radios operate by encoding, transmitting, and decoding sound waves. The signal is represented by binary numbers—1s and 0s—that correspond with voltage values. Inside the radio, the vocoder—an analysis/synthesis system used to reproduce human speech—encodes the transmission. The radio sends the signal, and the vocoder on the receiving end decodes it.

In addition, the software in digital radios contains an algorithm that recognizes the difference between voice and background noise and cancels undesirable audio for clearer, cleaner sound quality. Digital two-way radios can also include software applications that integrate into existing computer networks and phone systems. As a result, digital radios can enable a multitude of additional functions, including GPS, text messaging, and other information sharing, communications, and operations programs and capabilities.

By proactively transitioning to digital radios now, your organization will enjoy greater benefits immediately, and your fleet is ready for the high-efficiency, app-driven innovations coming in the future.

FIVE REASONS TO GO DIGITAL

  • Improved Audio Quality • Enhanced Clarity throughout the Coverage Range
  • Greater Efficiency • Extended Battery Life • Applications that Add Functionality
  1. Improved Audio Quality: Digital technology reduces external background noises during

transmission, thereby making the digital technology platform ideal for situations such as

noisy manufacturing and processing plants, or outside in windy conditions.

  1. Enhanced Clarity throughout the Coverage

Range: While an analog radio is capable of producing a clear signal within its peak performance range, once the signal moves too far from the transmit point, the analog audio will slowly fade out until it is unrecognizable. By contrast, a digital signal stays much stronger and clearer to the limits of the coverage range.

  1. Greater Efficiency: Digital radios operate in

Dual-Capacity Direct Mode (DCDM), which means that radios can share the same channel by alternating time slots. These time slots move incredibly fast, and since they alternate, more simultaneous talking paths are possible on each channel with no degradation. Plus, key information such as unit ID, status buttons, and enhanced text messages can be embedded into a single digital radio channel. In many cases, migrating from analog to digital allows users to increase talk paths without a repeater.

  1. Extended Battery Life: Since digital radio transmitters are not constantly “on,” digital

radios generally have a significantly longer battery life than analog models. When events run all day, that can mean the difference between efficient communications for the full cycle or the headache of a number of dead batteries that need swapping out and recharging.

  1. Applications that Add Functionality: Software applications are available to optimize digital

platforms using integrated Internet Protocol (IP) networks. For example, some of the leading app providers for Motorola MOTOTRBO digital radios include:

TABLETmedia

NeoTerra Systems

Twisted Pair

TurboVUi

Teldio

MOVING TO DIGITAL

For those switching from analog to digital, there is good news: Digital platforms provide a migration path that allows for simultaneous use of digital and analog radios. Backward compatibility allows organizations to gradually replace analog devices with newer digital models without the added stress of shifting to a new system. Also, many analog radio accessories are compatible with digital devices.

THE MOTOROLA CP200 AND CP200d

The existing CP200 is one of the most popular two-way radios ever produced! So the question is: How can you improve on the Motorola CP200? The answer: By creating a version that leverages all the benefits digital delivers.

Introducing… the CP200d digital two-way radio, a new model that retains the same simplicity and durability that have made Motorola’s CP200 the industry standard for years. The new CP200d uses a nearly identical form factor with similar operation. Plus, this highly flexible digital model is backward compatible, so it uses the same chargers, batteries, and speaker-microphones.

Motorola is adding sensible options to your two-way radio fleet by offering the existing CP200 device in the CP200d digital-capable version that can be fully converted from analog to digital operation at a later date. That means you can use a phased migration approach by using your new CP200d as an analog device now, and then with a simple programming change, switch to digital at any time in the future. Or, you have the option to take out-of-the-box delivery of the CP200d as a digital device from the get-go.

THE SHIFT TO DIGITAL, why NASCAR choose Motorola

NASCAR officials have enthusiastically embraced MOTOTRBO, and they applaud the benefits it has brought to the NASCAR experience. Smooth Management of Communications Traffic MOTOTRBO “does a super job for us,” according to Kerry Tharp, Director of Communications, NASCAR. “You have to communicate pre-race, during the race, and most importantly for us, post-race because when the race is over, that’s when our media operation kicks in for us full-bore. We bring in our top three drivers for interviews; we bring in our winning driver to the victory lane, and we also check in on the garage to make sure that post-race is going along as it should. We have to make sure we’re communicating quickly and concisely. Through MOTOTRBO, we’re able to do our jobs a whole lot better than we have in the past.”

A Clear Road for Communications Digital provided a measurable improvement over NASCAR’s old system, which sometimes had a slower response time. “MOTOTRBO has taken NASCAR to a whole new level.” Steve Lowery, Chief Scorer, NASCAR, explains, “With the old system, there was a lot of interference. Sometimes you couldn’t hear at all because of static. With MOTOTRBO, it’s much clearer.”

Consistency and Reliability

 You’d Expect from a Winner According to David Hoots, Managing Event Director, NASCAR, one of the most important benefits is “extended battery life because some of our days are extremely long. We have to be able to communicate consistently and reliably. MOTOTRBO has done a super job for us.” Hoots adds that MOTOTRBO is the first step toward an even more comprehensive communications system: “We took the opportunity to start with a very solid foundation and we will grow with the capabilities the radios offer. With a digital system, we’re going to reap the benefits for years to come.” “ With the old system, there was a lot of interference. Sometimes you couldn’t hear at all because of static. Now, with MOTOTRBO, it’s much clearer.”

Robust Enough for the Toughest Environments The NASCAR study, Hoots recalls, determined that the organization needed “one clear and uninterrupted communication system, and because we move from venue to venue, we’re faced with a big challenge.” The robust, durable and adaptable MOTOTRBO system was able to move from location to location – over 56 events every year, almost every month of the year – for quick deployment and certain performance. “Reliability,” says Hoots, “is of utmost importance. We cannot have a product that is going to fail. We must have the most robust system possible, so MOTOTRBO is the right system for us.” According to Michael Helton, President, NASCAR, “Fans have become interested in the entertainment aspect of listening in, so we still want an analogue system going out for fans who still use analog radios.” The ability of MOTOTRBO to support digital and analogue communications made it the perfect selection for

this blended environment that had to accommodate fans in the stands who want to scan for instant updates using older analog radios.

Twice the Capacity

MOTOTRBO is able to manage large numbers of radios by utilizing TDMA – time division multiple

access – which divides the channel into time slots for greater spectrum efficiency. TDMA enables each single repeater to do the work of two repeaters for enhanced call management with private, group, and system-wide calling capability. Digital Means Clarity MOTOTRBO supports audio quality with digital clarity and noise-canceling technology so that everyone is able to connect with one another and communicate more efficiently. MOTOTRBO radios contain a digital signal processor (DSP) that fine-tunes the audio. When a user connects an IMPRES™ intelligent audio accessory to a MOTOTRBO radio, the accessory provides the radio’s DSP with a unique set of audio parameters to shape the microphone and speaker frequency responses, ensuring the maximum clarity, volume, and intelligibility of each communication. “ Fans have become interested in the entertainment aspect of listening in, so we still want an analog system going out for fans who still use analog radios.”

Batteries Go Farther on a Single Charge MOTOTRBO is able to maintain consistent, reliable communications. All digital radios provide improved battery life, and because TDMA digital systems

utilize batteries more efficiently, users have received up to 18 hours of operation after quick-charging a standard nickel metal hydride battery. Talk-time is now extended and personnel spend less time returning to base to recharge their radios or pick up fresh batteries.

Robust Enough to Take on the Road

One key advantage of MOTOTRBO is that it’s designed to be packed up, moved to a new location and set up, only to be taken down days later and moved again. To withstand that kind of constant use, a radio has to be strong, and MOTOTRBO has proven to be very strong, robust, and durable.
