The anechoic chamber is a closed shielded room mainly used to simulate open fields and also used for radiated radio disturbance (EMI) and radiation sensitivity (EMS) measurements. The size of the radio wave anechoic chamber and the selection of radio frequency absorbing materials mainly determined by the layman size and test requirements of the equipment under test (EUT).
The global anechoic chamber market expected to spur market value with USD 2.0 billion with anticipating CAGR in the forecast period from 2020-2027. The growing demand for modern gadgets, emerging aerospace industry, and advancement in the healthcare sector is propelling the market demand for the global anechoic chamber.
The full-wave anechoic chamber reduces the interference of the external electromagnetic wave signal to the test signal. At the same time, the electromagnetic wave absorbing material can lessen the multipath effect caused by the reflection of the wall and ceiling on the test result. It is suitable for the experiment of emission, sensitivity, and immunity.
With the rapid development of consumer electronics products, the rise of mobile internet, medical electronics, automotive electronics, and other applications has promoted the use of wireless technology, and electromagnetic compatibility EMC testing has become particularly important.
The environment required by the EMC test is an open field or an anechoic chamber. Due to the increasing electromagnetic “pollution” and the dependence of the open area on the climate, the anechoic chamber has become an economical alternative. Also, as the electromagnetic compatibility standard becomes higher and higher, the importance of the anechoic chamber will increase day by day, and the demand for high-performance anechoic rooms will continue to grow.
Moreover, the development of digital products such as flat-screen TVs and digital cameras is changing with each passing day. The popularization of mobile phones has promoted the increasingly widespread application of wireless technology in the medical, automotive, and other industries. At the same time, it has inevitably caused many staggered environments. EMC (electromagnetic compatibility) technology to suppress radiated noise has become particularly important.
The anechoic chamber and measurement system are essential evaluation equipment to support EMC technology. The best management of the noise environment through the radio wave darkroom can enable people to use electronic equipment with confidence.
To improve the user experience, the radio wave anechoic chamber used for OTA testing helps in testing the product performance and function are evaluated by configuring a multipath environment (approximating a real situation) using radio wave reflectors. The anechoic chamber can prevent the interference of external electromagnetic waves and prevent these electromagnetic waves from leaking to the outside. It functions as a shielded room, and radio waves cannot reflect inside. Cellular communication legislation and previous standards, the need for testing of various other radio communication standards (such as WLAN, Bluetooth, etc.), EMC, and SAR are increasing. Therefore, the Internet of Things and equipment suppliers and test organizations urgently need to support these new tests.
With the continuous advancement of bioelectronic technology, the operating frequency band of medical devices continuously expanded, and the external electromagnetic energy has also gradually increased. Also, the increasing environmental electromagnetic pollution, anechoic chambers are requiring as it provides the highest possible shielding attenuation to perform highly sensitive testing without distortion.
Based on the type, the global anechoic chamber market bifurcated into the Semi Anechoic chamber and Full Anechoic chamber. The semi-anechoic chamber segment estimated to dominates the maximum share of the global anechoic chamber market in the forecast period from 2020-2027. Semi-wave anechoic chamber uses conductive floors and does not cover the absorbing materials. The semi-anechoic room simulates the ideal open field situation, that is, the field has an infinitely useful conductive ground plane. In a half-wave anechoic chamber, since the ground not covered with the absorbing material, a reflection path will be generated so that the signal received by the receiving antenna will be the sum of the direct route and the reflection path signals. Thus, it allows the user to have better and accurate testing with less damage.
Based on the end-use application, the global anechoic chamber market classified into Automotive, Military & Defense, IT & Telecom, Consumer Appliances and Electronics, Medical, and Others. The IT & Telecom segment dominated the largest market share in the global anechoic chamber market. The undesirable electronic noises can affect the performance of the surrounding equipment and the production of other sensitive instruments, making their operation unacceptable. EMI / EMC is suitable for most devices that use electrical energy, which can quickly produce undesirable electronic noise. IT & telecom industry require EMC testing done to test the performance of hardware and software and for checking the electromagnetic interference. It is owing to the emerging information technology equipment, and wireless mobile subscribers have reduced wired mobile users. Therefore, increasing unparalleled equipment in the system has reduced the space and fuel the chances of electromagnetic intrusion.
Based on geography, the global anechoic chamber market segmented into North America, Europe, Asia Pacific, South America, and Middle East & Africa. The Asia Pacific is the world’s fastest-growing anechoic chamber market, accounting for the largest share in the global market. It is mainly due to the emerging telecommunication sector, adoption of 5G technology, increasing aerospace production owing to the availability of cheap labor. Moreover, growing technology and the adoption of modern gadgets are bolstering the market growth of the anechoic chamber in the Asia Pacific.
Companies such as TDK Corporation, ESCO (ETS), MVG, Eckel Industries, Albatross Projects, and others are key players in the global anechoic chamber market.
