Smartphones Help Push Network to
 Dismounted Soldier

November 1, 2013
By Rita Boland

The U.S. Army’s goal to push the network down to the dismounted soldier is now reality as Rangers units and the 10th Mountain Division begin employing Nett Warrior. But developers are not resting on their laurels. They already are adding advancements to increase capability and improve functionality.

Ground Combat Vehicles to Gain Common Technology Architecture

November 1, 2013
By George I. Seffers

U.S. Army officials are standardizing the information technology architecture on many current and future ground combat vehicles. The effort is designed to reduce the size, weight and power of electronics; reduce life-cycle costs; and improve interoperability while providing warfighters all of the data and communications capability required on the modern battlefield.

Korean Military Networks Flourish Under Duress

November 1, 2013
By Robert K. Ackerman

The signal brigade in charge of U.S. Army communications in the Republic of Korea is incorporating new technologies and capabilities with one eye on ensuring success and the other eye on the hostile neighbor to the north. System improvements such as the advanced Warfighter Information Network-Tactical, voice over Internet protocol and a Korean theater version of the Joint Information Environment are designed to give allied forces a significant edge should war break out.

Army Signal Expands Its Reach

September 1, 2013
By Robert K. Ackerman

The U.S. Army Signal Corps is expanding the work its personnel conduct while dealing with technology and operational challenges that both help and hinder its efforts. On the surface, Army signal is facing the common dilemma afflicting many other military specialties—it must do more with fewer resources.

C4ISR Has Come a Very Long Way 
for Government and AFCEA

August 1, 2013
By Kent R. Schneider

 

My reflections on C4ISR are flavored by my recent reading of the book “From Pigeons to Tweets” (SIGNAL Magazine, April 2013, page 66) by Lt. Gen. Clarence “Mac” McKnight, USA (Ret.). In his book, Mac recounts the changes in every aspect of the U.S. Army Signal Corps and the defense environment over the course of his long and distinguished career. Most prominent among these changes were the evolution of technology and capability, and what this meant to command and control and intelligence over time. If you haven’t read Mac’s book, I recommend it.

Through the lens of my nearly 44 years in and around C4ISR, I have seen the transition from paper maps, acetate and grease pencils for situational awareness and single-channel push-to-talk radio, as well as laying and retrieving field wire and multipair cable; installing and continuously reinstalling tropo and microwave multichannel radio; and using couriers and liaison officers for much of our information sharing. I remember using torn-tape relay for message traffic. But I also remember implementing the Army’s first email system and the Army’s first wide-area network. And I am awed today by the tremendous capability that exists in computing, big data, mobility, cloud variants and security. I am amazed at the incredible bandwidth available down to the lowest organizational levels. I also am impressed with the vulnerability that has resulted from all this progress.

Building
 a Bigger,
 Better Pipe

Scientists at the U.S. Defense Department’s top research and development agency are seeking the best new ideas to provide a larger-scale mobile network to support an increasing array of bandwidth-hungry mobile computing devices for warfighters.

The Defense Advanced Research Projects Agency (DARPA) has issued a Request for Information (RFI) for new technical approaches that would expand the number and capacity of Mobile Ad Hoc Networks (MANETs) nodes available in the field.

“When we look at MANETs, it’s really tough to deliver networking services to more than about 100 users,” says Mark Rich, program manager, DARPA Strategic Technology Office. Those 100 users translate into approximately 50 nodes on a mobile wireless network operating in a forward location, generally supporting everything from tactical and operational systems to advanced video services. All of these functions are carried on a service that is largely dependent on highly secure digital radio systems. Once that limit is reached, network services begin to deteriorate in quality and effectiveness. To support larger deployments or to cover a greater area, military communications experts usually knit smaller networks using other available means, such as satellites.

Smartphone Increases Soldier Intelligence

July 26, 2013

10th Mountain Division U.S. Army Rangers and soldiers on the battlefield are now wearing commercial smartphones to communicate with each other and higher commands. Nett Warrior is a Samsung Galaxy Note II with its commercial memory wiped clean and Army-developed software loaded. It displays the locations of fellow soldiers, allows placement of location digital chem-light markers, and enables warfighters to communicate through texting. This information is then relayed to commanders over encrypted tactical radios.

“We are beholden to the commercial industry,” Jason Regnier, project manager, Nett Warrior, PEO Soldier, says. At approximately $700 per unit, buying the devices commercially costs substantially less than procuring similar devices from contractors, he explains.

In addition, the ability to buy newer versions of a device as technology matures means soldiers can transition to up-to-date capabilities as they develop. “So when the Note IIs are gone, they’re gone. Then we’ll have to be ready to buy Note IIIs or whatever it’s going to be,” Regnier relates.

Before the smartphones are integrated into a Net Warrior system, most of the communications capability is disabled, including the cellular antennas and the Wi-Fi and Bluetooth capabilities. A USB connection with a soldier’s hip-mounted Rifleman Radio enables communication.

Spectrum Management System Deploying to Afghanistan

July 11, 2013
By George I. Seffers

The U.S. Army is currently delivering a new and improved Coalition Joint Spectrum Management and Planning Tool (CJSMPT) to divisions scheduled for deployment in Afghanistan. The software automates the spectrum management process, dramatically reducing the amount of time and paperwork associated with spectrum allocation and mission planning in a tactical environment.

For operational security reasons, Army officials cannot reveal exactly which divisions will be receiving the systems or when, but for the next few months, they will be working to get the system out to Afghanistan.

Warfighters are continually confronted with an increasingly crowded radio spectrum—too many devices transmitting on a limited range of frequencies and interfering with one another. Poor spectrum availability can have a devastating effect on operations, and spectrum management normally is a complex and time-consuming process involving frequency access requests that must be approved at multiple levels. “There’s a lot of paperwork associated with the spectrum management process. There are thousands of these [requests] that have to be prepared, submitted, received and reconciled down at the brigade level. Normally, this could take days or even weeks in preparation for a mission or deployment, and CJSMPT can do this in a matter of hours. It provides automation to the spectrum manager to reduce the complexity of his tasks,” says Bob Shields, chief of the Spectrum Analysis and Frequency Management Branch, Space and Terrestrial Communications Directorate, U.S. Army Communications-Electronic Research, Development and Engineering Center (CERDEC), Aberdeen Proving Ground, Maryland.

A Joint Environment Changes Everything

July 1, 2013
By Max Cacas

Rear Adm. Robert Day Jr., USCG, assistant U.S. Coast Guard commandant for command, control, communications and information technology, sees the Joint Information Environment as an opportunity to resolve some of the most pressing information technology problems in the years to come as he faces a future with more challenges and fewer resources. He says a military-wide common operating environment will establish “enterprisewide mandates that programs cannot ignore.”

The admiral told the recent AFCEA Solutions Series–George Mason University Symposium, “Critical Issues in C4I,” the Joint Information Environment (JIE) will allow for more efficient system configurations and facilitate consolidation of the Coast Guard’s information technology work force. As the director of the U.S. Coast Guard Cyber Command, he also is mindful that the JIE will improve his ability to control what devices are attached to the network, giving him, for example, the opportunity to quickly detect and order the removal of an unauthorized USB thumb drive inserted into a secure network computer.

Hewing to the reality of doing more with less, the admiral also told conference attendees that within the next eight months, the Coast Guard is expected to move to the U.S. Defense Department’s enterprise email system. Adm. Day stated that even though this move initially may cost more in some cases, the long-term benefits to the service will mitigate and justify some of those costs. In addition, acknowledging the futility of reinventing the wheel, he noted that the Coast Guard is adopting the U.S. Air Force’s Virtual Flight Bag, which replaces nearly 300 pounds of printed manuals and charts carried aboard aircraft by crews. Apple iPads will be loaded with digital copies of the same material.

Information Agency 
Changes Security Approach

July 1, 2013
By Robert K. Ackerman

The increasing use of readily available and inexpensive commercial technologies by the military is changing the way the Defense Information Systems Agency provides information assurance. As these technologies are integrated into the Defense Department information infrastructure, the agency is adjusting its approaches to providing security for its networks and the data that reside on them.
