Comparing TDMA and FDMA in DMR Systems
Digital Mobile Radio (DMR) systems offer two primary methods for achieving increased capacity: Time Division Multiple Access (TDMA) and Frequency Division Multiple Access (FDMA). While both approa...
Understanding the Capacity Benefits of DMR
Digital Mobile Radio (DMR) stands out as a versatile and efficient communication solution, offering a predictable doubling of capacity within existing 12.5 kHz licensed channels. This remarkable f...
The History of DMR Digital Mobile Radio
The history of DMR traces back to 2005 when it began as a collaborative effort among leading mobile radio manufacturers to support the standardization process led by the European Telecommunication...
The Mission and Objectives of DMR Digital Mobile Radio
The mission of the DMR Association is to ensure that DMR remains the most widely supported digital business radio standard worldwide. To achieve this mission, the Association operates with several...
Why DMR Digital Mobile Radio is the 21st Century Digital Radio Standard?
DMR, or Digital Mobile Radio, has emerged as the premier digital business radio standard of the 21st century. This distinction stems from its widespread support, interoperability, and forward-thin...
What is the MIL-STD-810 Rating for two way radios.
MIL-STD-810 RATINGThe MIL-STD rating is a standard used by the US military, to determine and accredit whether equipment is suitable for use in military applications. Products that meet the MIL-STD ...
What is the difference two way radio between IP67 and IP68?
We always talk about the IP rating of the devices, but what really separates the two top ratings? The article below explains the key differences.IP67 VS IP68There are many high spec phones on the m...
Why DMR Radios Should Utilize AES256 Technology?
Two-way radio systems inherently offer greater security compared to many other wireless communication alternatives, operating on private networks that are less susceptible to eavesdropping. Analog...
Why is it said that the right choice for professional two-way digital radio is TDMA tehnology?
For professional users, digital two-way radio in licensed bands is the wave of the future. Whether they’re using analog radio today, or looking to implement their first two- way radio system, busin...
Why is DMR more efficient in terms of spectral utilization than other technologies?
As we have discussed, two-slot TDMA offers a proven way to enable 6.25 kHz equivalent efficiency in licensed 12.5 kHz repeater channels. This doubles per-channel communications capacity, while sati...
Why DMR radio has longer battery life ?
One of the biggest challenges with mobile devices has always been battery life. In the past, there have only been a couple of options for increasing the talk time on a single battery charge. One wa...
Why is it said that DMR are more advanced features and flexibility
In a traditional FDMA two-way radio implementation, each transmission occupies a full 12.5 kHz channel. A single channel can accommodate a single, half-duplex call. Proprietary implementations that...
Why DMR can save equipment costs ?
Compared to 6.25 kHz FDMA, two-slot TDMA allows you to achieve 6.25 kHz equivalent efficiency while minimizing investments in repeaters and combining equipment. This is one reason why TDMA is so we...
TDMA stands for “Time-Division Multiple Access.” Like FDMA, or “Frequency-Division Multiple Access,” TDMA is a technology that allows multiple conversations to share the same radio channel. Althoug...
Advantages of digital two-way radio
Since the first wireless transceiver was installed in a Bayonne, New Jersey police car in 1933, two-way radio has been a mission-critical technology for police, firefighters, search and rescue work...
Push to video is another critical communication innovation that was made available by the increased data speed in mission critical applications.At the press of a button, or automatically triggered ...
