Software Defined Radio (SDR) Market Forecast By End-use Industry 2014-2020

We are seeing a monumental movement in the radio communication industry, as this very technical article shows the transition from hardware to software within the radio communication industry is just around the corner. With 3G and 4G providing Data and Voice Comms covering large distances, RF communication will find it hard to compete, the simple answer seems to be Tetra, but is that long term? There will always be a need for point to point communications, but larger comms infrastructures could possibly be managed in a different way.

With the evolution of digital electronics the radio market and communication technologies have evolved a lot. Though the concept of software defined radio (SDR) is not new, in the recent years, this market has undergone many changes in terms of technology and uses. SDR is a type of radio communication system where communication is carried out by the use of software on embedded system or personal computer instead of implementing hardware such as filters, amplifiers, mixers, detectors, demodulators and modulators, among others. SDR are capable of transmitting and receiving a wide spectrum of frequency. When the data from a source is converted into digital format, the remaining activities involved in radio communications are carried out with the help of software driven automated functions.

SDR optimizes the tactical information system as embedded software used in SDR helps in the dynamic selection of the communication channel. The number of digital service users is increasing resulting into the improved adoption rate of software defined radio. Public safety, military and commercial use are the three major end-use applications of SDR systems. The demand for SDRs in expected to increase in coming years owing to efficiency and cost effectiveness offered by them. The industry has undergone t ransformation from analog to digital. Thus, the advance capabilities of digital radio are expected to drive the growth of SDR market. Multiple regulations govern the SDR market and this affects the market growth and trends. For instance, the Federal Communications Commission (FCC) legally created a newer class for equipment of SDRs that had streamlined equipment authorization procedure.

Military modernization programs being carried out by several countries such as South Korea, India, Germany, Japan and the U.S and the interoperability provided by SDR are major driving forces for SDR market. The issues faced in the integration of the various sub systems pose a challenge to the SDR market. Further, the development of software platforms, technologies and tools, which allow flexible specification, design and implementation of radio systems, is another significant challenge. Players in software defined radio market have potential opportunity in technical advancements of SDR techn ology such as resolving the problem of frequency congestion, wide frequency range (spectrum) and improved broadcasting services in future.

Software defined radio market is segmented on the basis of type, end-user application and geography. On the basis of type of SDR, the market is segmented into ideal software defined radio, baseband software defined radio (BBSDR) and high frequency software defined radio (HFSDR). On the basis of end-user industry, SDR market is segmented into defense industry, telecom industry, manufacturing plants, public safety vendors and personal use. U.S. Canada, Japan, France, Brazil, South Korea, India, Germany and Italy have emerged as the leading countries for software defined radio market.

Some of the key vendors in software defined radio market are BAE Systems PLC, Elbit Systems Ltd., IndraSistemas, L3 Communications Corporation, Raytheon Co., Rohde & Schwarz GmbH & Co KG, Thales Group, Viasat Incorporated, SAAB AB, Rockwell Collins, Northrop Grumman Corp., ITT Corporation, Harris Corporation and Datasoft Corporation, among others.

This research report presents a comprehensive assessment of the market and contains thoughtful insights, facts, historical data and statistically-supported and industry-validated market data and projections with a suitable set of assumptions and methodology. It provides analysis and information by categories such as market segments, regions, product type and distribution channels.

We Have Listed Seven Different Communication Systems You Can Use At Your Event

There are many instances where people get confused when talking about types of headsets and the associated equipment. In this article, we are going to help you get a clear understanding of the different types of headsets and the associated equipment. With that said, it is important to note that the names that have been given below, are the actual names that need to be used. Without any further ado, lets get started;

In Ear Monitors

Also known as in-ear (or canal) headphones, these devices sit inside the user's ear canal, and they deliver great sound quality; they ensure a controlled and precise sound. They also fill the ear's entrance, thus are very effective at sealing out any unwanted external noise. These devices include a transmitter which is controlled by an audio engineer which then transmits to the belt-pack on the user. The in ear monitors allow freedom of movement and are commonly used by modern pop a rtists. They're very small and allow them to comfortably hear the rest of the band, and also themselves (this is what's known as monitoring or foldback). Apart from artists, these devices are commonly used by audio engineers to hear the mix of the vocals and the stage instrumentation for recording studio mixing and/or live performance.

2 Way Radio Headsets

2 way radio headset is a communication device which can transmit and also receive signals. A two way radio headset allows the user to communicate with other people with similar 2 way radio headsets (and are operating on the same channel or radio frequency). 2 way radio headsets are readily available in mobile and also hand held portable configurations. The handheld 2 way radio headsets are also known as walkie talkie headsets or handie talkies. One thing to note about two way radio headsets, is that the user can either transmit or receive signals and not both at the same time.

Two Way Radio Covert Pieces

These are quite similar to the Two way radios, however, they are much more discreet. Two way radio covert earpieces are usually used by security personnel as they prefer staying discreet. This type of walkie talkie headset is also ideal for the Door supervisors and security staff.

Wired Show Comms

Unlike Two way radios, these type of communication systems allow for both talking and listening even at the same time. These devices have a closed cup design, meaning they fully cover the ear which helps reduce the ambient noise. Wired show comms come in single muff and double muff versions. They get attached to the belt pack controller which is then physically wired to the system. Because of the cabling that's involved in wired show comms, there's less mobility thus are b est suited for managers and the static technicians. These specialist communication devices are also commonly used for calling shows.

Wireless Show Comms

These are very similar to the wired Show Comms, only difference is that their belt packs are wireless. The device and the belt pack are compatible which means that the users can freely and comfortably move around, thus are ideal for stage managers, front of house managers, among others. Just like the wired show comms, these devices also allow both talking and listening at the same. With that said, you should know that the wireless show comms are relatively more expensive than the wired show comms. Some of the other applications for these devices include, but not limited to; security personnel, broadcast, marines, theater, and colleges. They can also serve as convenient walkie talkie headset for events.

Radio Performer Headset

This is the device that's used by presenters and performers. This device allows for the user's voice to get fed into the sound system where the audience can get to hear them. This device is usually used in conjunction with the radio belt pack system. Most of the devices used today are generally very thin and skin colored which helps reduce visibility when the performer is on stage.

Presenter Talkback

These are the small ear pieces which you see the lead presenters on TV talk shows wearing. This device allows the producer (of that particular TV talkshow or program), to communicate to the lead presenter and update them on the show's progress. This may be done using a system known as in ear monitoring. Alternatively, wireless show comms systems can also be used.
