The MobilCMDR receives microwave signals from two different antennas, and then combines the signal inputs to provide a superior non-line-of-sight video. This combining technique with diversity reception is known as maximum ratio combining. All of the features of the MobilCMDR receiver, including, the enhanced high brightness screen, (the monitor can be seen even in sunlight) enables a high-quality COFDM receiver/monitor for government, law enforcement and security applications.
In order to address a wide range of applications, the device features on screen display, Ethernet monitoring for remote control access, and IP encapsulation for Internet broadcast. It can deliver either SD or HD (SDI) video, depending on which built-in decoder is specified. It is designed for intuitive, straightforward operating and is housed in a compact chassis with optional recording capabilities. The MobilCMDR is available in L-Band, S-Band and C-Band frequency ranges and has AES decryption capabilities that make it well suited for applications ranging from public safety monitoring to covert surveillance.
The MobilCMDR supports a wide range of video input and output formats, including ASI and HD/SD SDI. This versatility will allow the unit to function in many receive applications including portable, remote and command center operations. Further, offering H.264 decoding, it displays COFDM video transmissions using a built-in internal eight inch class 16:9 format screen. The unit also allows for multiple remote viewers to monitor the same video simultaneously. Well suited for the variety of field applications, the MobilCMDR’s milled aluminum chassis and ergonomic hand grips are weather resistant.
The administration software package also allows users to configure and store up to 16 custom preset configurations. The presets can store as little or as much information as the administrator wishes. The simplicity of this configuration enables the end user to completely control this process. These values can then be locked in place, providing simple and reliable operation. The MobilCMDR employs AES encryption preventing unauthorized viewing from decoding or eavesdropping.
The unit’s On-Screen Display (OSD) feature exhibits an information summary, and also includes signal strength, demodulator lock, decryption active and decoding indicators. This is especially important in remote operations with hostile environmental conditions. These figures give the ability to the user to ensure interoperability between the transmissions systems and the receive systems.

Yes, readers are indeed interested in a lot more of the technical details. Of course, it would be over some heads, but how better to learn? I was reading "electronics" magazine very shortly after I learned to read. Did I understand much of it? No, but I certainly found it interesting. On the other side, I was not one who would be purchasing any of the materials advertised at the time.
Hi, Yes the readers are interested in those details. This is an application based piece. Readers asked for more of them when I asked, so this is part of what I call "RF in Action." I invite you to look around the site http://www.eetimes.com/design/microwave-rf-design and sign up for the newsletters to get a better idea of what we do.
This is a good "sales flier". It's a shame that it does not include more technical details about RF and other technologies included in this product as I guess the audience of this portal is particularity interested in such details. On the other hand, I doubt very much that the potential customers are reading these pages...
OFDM is the technique being used in most of the sophisticated wireless applications, and it have prove itself.
Now there will be so many applications like this coming up in line as the world is changing towards wireless links and each application is trying to make use of wireless technologies for betterment.
There is no doubt about it that OFDM will be the underlying technology for all of these applications.
