The present invention relates generally to radio interfaces, and more particularly, to a universal radio interface that permits various types of radios to be mounted to a vehicle or other mobile platform.
Tactical and other types of radios are commonly used for field applications when cellular, wired, or other types of network connections are not available. Tactical radios can provide push-to-talk communications as well as data transmission and networking capabilities. In part because radios transmit over limited distances, it can be advantageous to mount radios to a mobile platform to transport the radios from location to location and to permit the use of larger power sources and longer antennas that improve signal transmission. Examples include mounting radios to a car, truck, watercraft, airplane, unmanned aerial vehicle (“UAV”), or a backpack carried by an individual.
Radios vary significantly in performance characteristics and form factors to accommodate different use cases and depending on the manufacturer. The type of radio selected for a given application depends on factors that include the desired transmission distance, the number of users on a network, desired data transmission speeds, bandwidth requirements, and the mobile platform used to transport the radio, among other factors. In some cases, multiple types of radios must be used at the same time, or radios must be swapped out between uses to accommodate different use cases.
Using multiple types of radios presents significant challenges particularly when the radios must interfaced with a mobile platform. Mobility and power requirements limit the number of radios that can be mounted to a mobile platform, such as a UAV where space is limited and additional weight impedes flight performance.
Swapping radios between applications is often impractical owing to the fact that radios have different connectors and form factors depending on the manufacturer or type of radio. For instance, radios may require a different number of antennas, distinct mounting configurations (e.g., varying fastener configurations or brackets), or varying data connectors and cabling (e.g., Ethernet, rounded, or DB9 pin connectors). Switching radios between applications, therefore, requires not only replacing the radio unit itself but also replacing the mounting hardware as well as the data and antenna connectors and cables.
To address the challenges observed with conventional mobile radio systems, it is an object of the present invention to provide novel universal radio interfaces that allow mobile platforms to accommodate different types of radios that can be efficiently swapped out depending on the desired application or radio manufacturer.
Disclosed herein is a universal radio interface system for mounting a radio to a communication platform. The communication platform itself can be mounted to a stationary platform, such as a ground station, or to a mobile platform, such as an unmanned aerial vehicle or automobile. The system includes a radio module and a radio tray. The radio tray includes an exterior face, an interior face, a tray opening that extends between the exterior face and the interior face, and one or more tray casing sidewalls extending outward from the interior face. The tray casing sidewalls define an interior void. The tray opening and the interior void are sized to accommodate the radio module. The radio module is couple to the radio tray and seated at least partially within the tray opening and interior void.
The system further includes an universal interface housing that has an interior cavity, one or more guide ports that extend from an exterior of the universal interface housing to the interior cavity, and a mounting surface coupled to the communication platform. The guide ports can be sized to accommodate cabling that connects the radio module to the communication platform. The cabling can be antenna cabling, power cabling, or data cabling, among other types of cables. The interior cavity sized to accommodate the tray casing sidewalls. The radio tray is coupled to the universal interface housing and the tray casing sidewalls are seated at least partially within the interior cavity.
In one embodiment, the universal radio interface system includes an elongated tooth formed on an exterior surface of the tray casing sidewalls. The tooth fits within an elongated radio tray guide formed as a groove on a surface of the interior cavity when the radio tray is coupled to the universal interface housing. Fitting the tooth within the radio tray guide helps to stabilize the radio tray within the universal interface housing.
The system can also include a radio tray backing coupled to the tray casing sidewalls and seated within the interior cavity of the universal interface housing. The universal interface housing can be formed with an universal backing tray access that extends from the exterior of the universal interface housing through a sidewall of the housing to the interior cavity. The universal backing tray is coupled to the universal interface housing and seated at least partially within the universal backing tray access. The universal backing tray has a mounting plate affixed to the universal interface housing, a spacer extending from the mounting plate into the interior cavity, and a universal backing tray face coupled to the spacer and frictionally engaged with the radio tray backing.
In yet another embodiment, the radio tray backing has at least one antenna port sized to accommodate antenna cabling that connects to the radio module and to the communication platform. In that embodiment, the universal backing tray face has at least one antenna connection point extending through the universal backing tray face. When the universal backing tray face is frictionally engaged with the radio tray backing, the antenna port of the radio tray backing is aligned with the antenna connection point of the universal backing tray face. This allows cable to be fed through the universal radio interface system from the radio module to the communication platform.
The radio tray backing comprises at least one a universal connector slot sized to accommodate additional cabling (besides the antenna cabling) that connects the radio module to the communication platform. In that case, the universal backing tray face has at least one universal connection point extending through the universal backing tray face. When the universal backing tray face is frictionally engaged with the radio tray backing, the at least one universal connector slot of the radio tray backing is aligned with the at least one universal connection point of the universal backing tray face.

Disclosed is an universal radio interface system that allows different types of radios to be installed on a mobile platform. After a radio is installed, the radio can be efficiently removed and replaced with a different type of radio without having to change cabling, connectors, or mounting hardware. Eliminating the need to change cabling and connectors allows the cables and connectors to be designed prior to radio installation to optimize signal propagation regardless of the type of radio that is installed. For instance, in a multi-antenna system, each of the cables leading to an antenna can be designed to be the same length with the same number of connectors so that the resistance and other electrical properties are the same across each antenna cable. This in turn helps ensure uniform signal quality for each antenna. Additionally, the number of connectors can be minimized to mitigate the signal loss that occurs across a connector.
The present universal radio interface system finds particular applicability to installing tactical radios on UAVs, as illustrated in
Turning to
The radio tray 110, radio tray backing 80, and universal interface housing 20 each include ports that accommodate a wide array of connectors and cabling configurations that depend on the type of radio and radio manufacturer. The ports allow an installed radio module 200 to connect to subsystems and equipment on the mobile platform, such as a power subsystem, data ports for computing modules, data ports for communication to ground systems through a tether data cable, or the antennas 11 shown in
Radios are replaced by swapping out the radio module 200 itself along with the radio tray 110 and tray backing 80 that are adapted to fit the type of radio module 200 being installed. The radio tray 110 provides a mechanical interface to the universal interface housing 20 and allows different types of radios to be installed within the universal interface housing 20. The radio tray backing 80 protects an interior-facing side of the radio module 200 and accommodates the connector and cable configuration for the type of radio 200 being installed.
The radio module 200, radio tray backing 80, and radio tray 110 are assembled and installed within the universal interface housing 20 that provides a mechanical mount to a mobile platform. The radio module 200 is secured within the radio tray 110 and universal interface housing 20 in a manner that minimizes radio movement or vibration when the mobile platform is in motion to prevent damage to the radio. The radio tray 110 and universal interface housing 20 further protect the radio module 200, connectors, and cabling from weather elements or contaminants and provide physical protection from impacts. One or more of the components can be formed with a corrosion resistant material, such as aluminum or stainless steel, or covered with a corrosion resistant coating to further protect the radio module 200, cabling, connectors, and other hardware.
The universal interface housing 20 embodiment shown in
The interior cavity 26 includes one or more radio tray guides 28, which are keyed to ensure the radio tray 110 is installed with the correct orientation. The radio tray guides 28 are formed as channels that frictionally engage corresponding teeth 118 formed in the radio tray 110 to facilitate installation and to secure the radio tray 110 within the interior cavity 26 by ensuring the radio tray 110 does not translate about the cross sectional plane of first opening 22.
One or more radio tray securing apertures 32 are disposed on the opening frame 30 to receive fasteners that secure the radio tray 110 to the universal interface housing 20. The opening frame 30 is also formed with one or more handle mounting holes 34 that secure handles 14. Similarly, the top mounting surface 50 includes one or more mounting apertures 52 configured to receive fasteners that are used to secure the universal interface housing 20 to a mobile platform or to secure equipment to the universal interface housing 20 itself, as depicted in
The universal interface housing 20 incorporates one or more ports that extend from an exterior surface of the universal interface housing 20 through to the interior cavity 26. The ports accommodate cables and electrical connectors that place the radio module 200 in signal communication with various subsystems and equipment components on a mobile platform, such as antennas, power sources, or computing modules. Examples of ports include: (i) the Ethernet port 42 disposed through the first side wall 40; (ii) the communications port 46 disposed through the second sidewall 44; (iii) the four antenna guides 62 extending through the rear sidewall 60; and (iv) the power guide 64 also extending through the rear sidewall 60.
Those of skill in the art will appreciate that the ports and port configurations shown in the attached figures are not intended to be limiting. Varying numbers, types, and configurations of ports can be formed through the universal interface housing 20 to accommodate a wide array of mobile platforms, radio types, and radio manufacturers. For instance, additional communications ports 46 may be formed on the first sidewall 40, the top mounting surface 50, or any other sidewall or surface of the universal interface housing 20.
The universal interface housing 20 accommodates different radio modules 200 by replacing the radio tray backing 80 and the radio tray 110 when replacing the radio module 200. The radio tray backing 80 includes ports and openings that are adapted to fit the connector and cabling configuration for one or more types of radio modules 200. The radio tray 110 serves as a mechanical adapter that allows radio modules 200 with different form factors (e.g., varying dimensions, sizes, weights, shapes, etc.) to fit securely within the universal interface housing 20.
Example radio modules 200 are shown in
