The 5 Reasons Why We Still See Security Wearing Wired Security Earpieces

Advancement in technology has changed the form of how electronic devices look like, how they operate and consequently how we handle them. Devices such as radios have become smaller, lighter and wireless. The advent of Bluetooth has enabled radios to connect without any physical connections; notably saving us from the fuss of tangled and visible wires. The wireless earpieces are in use, but it is important to note that they have not completely taken over from the wired covert earpieces. With the convenience and technological advancement they offer, why is it that they have not replaced their wired counterparts especially in fields of operation? Here are a few thoughts:

Reliability

Wireless earpieces are not as reliable as the wired ones. The technology that supports Bluetooth communication has it that the source device (radio) and the receiving device (earpiece) have to be at a certain distance from each other and nothing should come in between the path of transmission of the two devices. This means that if any of the two requirements are not as anticipated, functionality is compromised. Wired earpieces do not have the complication of interference and limited bandwidth. When you are in a situation where reliability is crucial, where you cannot afford to lose connection, say you are out in the field on operation, it would make sense to use wired covert earpieces as they are easy to handle, making them more reliable.

Limited Operational Lifetime

For a wireless device to be operational, it needs to be charged. When out on assignment, the crew will need to ensure that they have fully charged the wireless earphones and carried a fully-charged extra battery. The batteries work on a limited operational lifetime which burdens the crew as they have to keep replacing the batteries every time. When pack ing batteries for replacement, one should pack enough to cater for both the radio and earphone. This is not the case with the wired pieces. For wired pieces, the crew only has to worry about a single cable that will connect the radio to the earphones. The wired option is therefore less of a burden to handle than the wireless ones.

Necessary Visibility

In some instances, the visibility of the wires, which the wireless earpieces work against, is crucial in making a statement. In a security situation, the wired pieces are visible to the human eye; they make the public aware of the security. The visibility in itself reinforces security, deterring any harmful or criminal practices that may take place. In such a situation, wireless pieces are of no use as no security statement will be made.

Disruption and Negative Interference

Wireless earpieces are vulnerable to signal disruption and negative interference. It is possible for a wireless-transmitted signal to be compromised- an activity that may cause threats and anomalies. A signal transmitted by wireless means may be decrypted and accessed by unauthorized people. At the same time, the signal may be compromised in a way the end product that is received as sound is not what was initially transmitted. Bluetooth is open to any form of interference, be it purposeful or accidental. The wired covert earpiece on the other hand greatly reduce the possibility of such malpractices as it would be hard to physically interfere with transmission without anyone noticing.



Misplacing earpieces during an incident

In the event of an incident, it would be hard to misplace a wired covert earpiece. This is becaus e, when an agent is on the move or if they make any vigorous movements, the radio earpiece might be detached from the ear but will not fall; it is tethered to the radio using the wire. On the other hand, a Bluetooth earpiece would probably detach itself from the ear, fall down and be misplaced as it has no physical tethering to the radio device. This will cost an agent a lot of time in looking for a misplaced device and even the responsibility of a lost device.

When it comes to technology, the feature advancements are normally made to our convenience and efficiency but in some cases, the old way of doing things would prove to be better. Wired radio earpieces have major advantages over their wireless counterparts, making them hard to phase out. What the wireless earpieces can function as at this point is as a complimentary device to the wired one.

Rifleman Radio is indispensable

When the army are on the battlefield, the equipment that they carry and the weight of it is paramount. Most two way radios are one of two things, light and easily breakable, with limited power, meaning limited range or heavy and the opposite to the above, Robust and able to transmit at a lengthy distance. The current development for a 2 channel that’s able to receive and transmit voice and data is an interesting concept. This article, that can originally be found here, give you more of the story.  

Nearly two years after the award of the Rifleman Radio contract, I made an appeal for new thinking by both the defense acquisition corps and the defense industry that now bears repeating.

Twenty-two months ago, the need for the Rifleman Radio was obvious as it is today. It provides infantry units with a relatively small and lower cost software-defined radio capable of transmi tting voice and data, such as maps, images and texts. The technology that defines this “workhorse” tactical radio was continuing to mature, resulting in today’s Rifleman Radio being far more reliable and capable than the LRIP-ordered radios from even three years ago.

This maturation process was being driven by ongoing investments in radio technology made by the defense industry, including Thales and Harris Corporation, the two companies selected by the Army to build the Rifleman Radio.

At that time, I noted that success in the Defense Department's new “Non-Developmental Items” or NDI strategy for the Army’s HMS program would require three things:



  • People. Bringing the right people together from three key groups for meaningful engagement: those defining the capabilities; those acquiring the capability for the government and industry; and those who have to deliver the capability to the Warfighter.


  • Dialogue. Creating ethical opportunities for face-to-face discussions with industry (not RFI dialogues) about the state of technology innovation and what is feasible to provide in a reasonable time and at a reasonable price.


  • Strategy. Building a shared understanding that this new NDI marketplace for tactical radios that requires industry to invest their own money to develop products will be one that delivers greater and greater capabilities over time, in other words, iteratively.




Where are we now? 

The Army is currently working to develop requirements for a 2-channel variant of the Rifleman Radio, a significant step in the Rifleman’s continuing evolution. The fundamental 2-channel communications capability â€" whether handheld or manpack variants â€" represents the future of tactical communications.

Two-channel capabilities for the small-unit leader radio like the Rifleman will meet the Army’s evolving tactical communications needs, with its ability to receive and transmit voice and data simultaneously, passing data to and from command to the unit.

The 2-channel Rifleman Radio will provide new capabilities without adding weight from extra radios and batteries. In short, it will provide the capability of two radios without burdening troops with lugging around two radios.

Viewed from a technical perspective, however, a 2-channel handheld radio represents an exponential leap in terms of complexity â€" it bears no relationship to the notion of “fusing two 1-channel radios together.”



Even the 2-channel HMS Manpack represents a tremendous technological leap forward, though it came with fewer space, size, power and weight limitations than the much smaller handheld Rifleman undoubtedly will. In short, the 2-channel Rifleman Radio will be a tall mountain to climb.

The future Rifleman 2-channel

The 2-channel Rifleman is an achievable reality, however, and speaking for Harris, we’re already well on the way to delivering this capability. The U.S. Special Operations Command (SOF) Tactical Communications (STC) 2-channel handheld radio being developed by Harris for special operations forces is leading the way to this future.

The STC radios are able to operate in the harshest environments and are specially designed to meet rigorous requirements. The STCs are small, lightweight, multiband and multifunction, with multi-mission capability to enable SOF teams to communicate over multiple channels simultaneously.

The Harris STC will provide the ability to receive ISR full-motion video and signals-based threat information. These handheld radios also will have built-in backward interoperability to communicate over legacy networks, and w ill be upgradable to integrate new capabilities as requirements evolve.

Although the Army’s requirements are still coming together, the 2-channel Rifleman most likely will trade fewer features for less cost. That said, there are many technical attributes related to the 2-channel capability that are likely to be applied from the Harris STC to the next iteration of the Rifleman.

The important takeaway here is that the Army’s continued commitment to evolving tactical communications has led industry to sustain its investment in advancing capabilities â€" and that formula has brought the 2-channel handheld much closer to reality.

Whether it is the STC or 2-channel Rifleman, the coming wave of new communication capabilities are the result of persistent innovations in myriad radio components: chip design, software, battery life, power consumption and antennas, to name a few.

As I pointed out in January 2015, the development of the Rifleman Radio would represent just the first iteration in the Army’s modernization of tactical radios ― a commitment that would deliver even more revolutionary capabilities over the next decade. But this will only happen if the Army maintains its end of the bargain by assuring industry that ongoing investments would be rewarded with purchases of the end products.

If BBP 1.0, 2.0 and 3.0 continue to be nurtured and “take root,” these radio technology capabilities will continue to evolve with each measured investment making possible continuing progress. Such an active NDI marketplace will ensure industry remains committed to R&D â€" and the beneficiary of this healthy dynamic is the warfighter.
