Why Digital Two-Way
Why Digital Two-Way Radio
The next-generation of two-way radio.
Professional two-way radio systems operating on licensed spectrum offer capabilities that other mobile technologies cannot. These advantages make it the clear choice for mobile organizations who require an affordable, flexible, highly reliable solution—along with the power and range available only in licensed bands.
With two-way radio, you can tailor a solution to meet your specific coverage and functionality needs. There's no need to deploy supporting infrastructure in a field situation—or to rely on often unreliable and always more costly public networks. A two-way radio solution typically pays for itself in less than 18 months compared with cellular or public carrier solutions. That means only a small up front investment and no recurring monthly fees.
The Digital Difference
Analog two-way radio use proves itself every day in countless installations around the world. But analog technology has reached its limits of innovation. Today a new platform is required to help you achieve new levels of performance and productivity. Digital technology represents that breakthrough.
Many businesses need more than the fundamental services that analog two-way radio can deliver. Licensed channels are becoming crowded and you may need more capacity. In combination with voice, you may also need access to data to improve responsiveness and productivity. Digital two-way radio provides a powerful, flexible platform that can be adapted to meet these needs and more. With MOTOTRBO you can benefit from:
- Expand digital voice, data, and control capabilities. delivered over a given slice of RF spectrum. With digital two-way radio, you can get increased capacity and flexibility to support more users in more ways.
- Lower licensing and equipment costs. Digital two-way radio solutions based on Time Division Multiple Access (TDMA) technology enable two virtual channels within a single 12.5 kHz licensed repeater channel. This provides twice the calling capacity for the price of one license. And because there's only one "real" channel, a second call doesn't require a second repeater.
- Clearer voice communications over a greater range. When signal strength drops off with distance, digital error-correction technology can accurately deliver both audio and digital content with virtually no loss over a far greater area.
- Static and noise rejection. Analog signals become distorted, producing audible static as signal strength degrades. By contrast, digital receivers simply reject anything they interpret as an error. TDMA divide power-intensive transmissions into two independent time slots. That means each individual transmission only uses half the battery power of an analog system transmitting at the same wattage.
- Additional functionality. Digital systems based on TDMA divide power-intensive transmissions into two independent time slots. That means each individual transmission only uses half the battery power of an analog system transmitting at the same wattage. Since transmitting is the most energy-intensive operation, digital two-way radios can typically function 40 percent longer between recharges compared to analog radios.
- Additional functionality. Digital two-way radio systems based on TDMA can provide additional features beyond two-way voice by using the second time slot for a second call, dispatch data, enhanced call signaling and control for future enhancements such as emergency pre-emption.
