What Is Long Range Digital Radios

Professional radio is now taking a big step forward – the transition from analog to digital. Government regulation and real-world needs are driving higher spectrum efficiency. Digital radios are becoming the only choice for more and more amateur radio enthusiasts to get started.
What is a digital walkie-talkie? A digital walkie-talkie is a walkie-talkie designed with digital technology. A digital walkie-talkie digitizes the voice signal and transmits it in digitally encoded form. The basic principle of a digital walkie-talkie is to convert analog voice into a digital signal and then modulate it to the radio frequency. Since the signal is digital, of course this device can also transmit data directly.
Why choose a digital machine?

1. Long range digital radios have a wider communication distance

Long range digital radios have a 25-40% higher communication coverage than analog radios and the sound remains strong and clear. This is achieved by converting your voice into a simplified digital language, which can be transmitted more effectively over longer distances. At the longest distance covered, even if the signal strength is similar, the digital voice will be clear and easy to understand, while the analog voice will be interfered and masked by static.

2.Long range digital radios have longer battery life

While analog and digital radios consume roughly the same amount of power in standby mode, once transmitting, digital radios are much more efficient, providing up to 40% longer operating time. This is critical for frequent and heavy users.

3.Long range digital radios have clearer sound

Long range digital radios are able to separate the user’s voice from background noise to ensure your critical communications are clear. Radio interference creates static on analog radios, making conversations difficult to understand. Because digital radios have automatic error correction, they are able to reconstruct speech and maintain clarity even when the signal is severely damaged.

4. Double the capacity without adding frequencies

With digital, you can instantly double the capacity of your existing 12.5 kHz channels and enable more people to communicate without worrying about privacy or interference. Digital walkie-talkies are able to create two separate “channels” in a 12.5 kHz space, allowing for expanded space without expensive licensing adjustments.

5. More secure calls

Digital radios are uniquely encrypted, making communications less susceptible to eavesdropping, ensuring the security of your calls.

6. More features

Many digital walkie-talkies support more intelligent functions, such as group calling, single calling, recording function, remote control, etc., which improves the flexibility and practicality of walkie-talkies.

If you want to have a long range digital radios,Retevis RT81 Dual Time Slot High Power UHF DMR Radio is a good choice.  It has a larger capacity battery to ensure your daily use. In addition, Retevis RT81 radio also has three modes: simplex, repeater and simplex dual time slot. In simplex mode, the walkie-talkie communicates in different time slots, which improves communication efficiency. In repeater mode, the walkie-talkie will increase the communication distance. Dual time slots expand the channel capacity and extend the communication distance.
I hope this article can give you a clearer understanding of digital walkie-talkies. If you have any ideas, please discuss with us.
