DIGITAL VEHICULAR REPEATER SYSTEMS (DVRS) OVERVIEW

X10DR Digital Vehicular Repeaters are a cutting edge alternative to traditional often cumbersome DVRS, DVR-LX P25, SVR, VRX1000 VRS7000 etc. They are also a very good solution for when Dual Control Head radio use is required. 

Anyone who has been involved with mobile radios for a few years is usually well versed on Digital Vehicular Repeater Systems or DVRS as they often refered to. From the early days of Motorola's PAC-RT Analog Vehicle Repeaters to todays Pyramid Communications' SVR-P250 and Futurecom's DVR-LX and VRX1000 Digital Vehicular Repeater models, they seek to address the age old challenge of how to best communicate once the user gets out of their vehicle.

The typical P25 DVRS (Digital Vehicular Repeater System) is a not so small albeit rugged, self contained 3-10W, radio base stations integrated with, usually a remote mounted mobile radio due to the combined RF equipment footprint.  Depending on the licensed frequency of operation, they often require large, cumbersome RF filters, so as to not inhibit communications reception range over the host mobile radio. But no matter their format, these traditional DVRS devices are designed to provide out of vehicle communications for Mission Critical personnel by using the high power mobile radio in the vehicle to extend the talk back range of the low powered, Press To Talk, low powered portable radios.

While these Digital Vehicular Repeater Systems are sometimes offered as Full Duplex Repeaters, the actual communication to the user is via traditional, two frequency simplex, portable radios, that as you know, means the user cannot receive when they are transmitting. This results in the user not knowing whether they have access to the system when they are transmitting, as is often the case on todays trunked radio networks especially during busy periods. Subsequently, when multiple vehicles attend an accident scene, chaos often reigns, except for the most highly DVRS trained officers or field personnel.

TRADITIONAL DVRS VS X10DR APPROACH?

Because of X10DR’s unique design approach, the following typical DVRS issues are addressed. Most importantly, It operates in full duplex mode meaning the users always know whether they are accessing the radio network via the host radio's systems tones. It also means they if two X10DR users respond at the same time they will hear each other. Secondly, there is no need for a licensed frequency.  X10DR operates on the 2.4Ghz License free ISM band which has shown it self to be well positioned for this type of dynamic on demand, outdoors, communication requirement. There are no shared voice channels and typically no interference from other users as the X10DR system creates a virtual ,private, AES encrypted, exclusive channel for each communication. This means no shared traffic, no lost audio and no lost vital radio alert or system tones. Importantly, X10DR new-age Digital Vehicular Repeater systems do not suffer from serious contention issues when multiple vehicles arrive at an incident or scene, which as many would know, is of major concern unless strict management protocol criteria is religiously followed.

WHAT ARE THE X10DR KEY ADVANTAGES

Our Mission Critical focused X10DR XLR units deliver exceptional out of vehicle communications back over the vehicle’s mobile radios. X10DR XLR models allow handsfree full-duplex communications on-site while maintaining full access to the vehicle’s mobile channel. All conversations are AES protected and are fully private and completely exclusive. Incredibly, the installed cost of an X10DR out of vehicle communications system is but a fraction of the cheapest traditional vehicle repeaters. 

 Dual Control Head Radio Use

For the more sophisticated user, the need fro Dual Control Head radio use is often required where the vehicle provides onsite services, such as a Fire Dept Pumper or a Utility Bucket Truck. A Dual Control Head is often fitted close to the control equipment, external from the vehicle cab. X10DR provides a perfect low cost wireless alternative to these often expensive to supply and install accessories from radio manufacturers.

Most of all, X10DR is simple and easy to use and requires little or no user training. It just works!
