Digital Vehicular Repeater Systems (DVRS) Technology Comparison
Digital Vehicular Repeater Systems (DVRS) Overview
X10DR Digital Vehicular Repeaters are a cutting edge alternative to traditional cumbersome DVRS, DVR-LX P25, SVR, VRX1000 VRS7000 etc. 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 latest DVR-LX 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 Elite Plus units deliver exceptional out of vehicle communications back over the vehicle’s mobile radios. X10DR Elite Plus 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.
Most of all, X10DR is simple and easy to use and requires little or no user training. It just works!
Is there a case for traditional vehicular repeaters:
Naturally, we understand there are those situations where users may frequently be required to walk miles into the wilderness, or into high rise buildings. While exceptional for most, these extended range considerations demand the use and cost of a traditional vehicular repeater with high powered portables.
Most importantly, we know the majority of users simply just require a good reliable “bubble” of solid communications around their immediate vehicle. The actual area where 95% plus of their real work duties are performed. Human nature ensures users will park their vehicle as close to the work area as is possible. It is here where X10DR truly excels. X10DR continues to provide the industry’s benchmark. A proven out of vehicle solution delivering practical and realistic long-range performance.
