Electromagnetic anechoic box/Shield box/Anechoic chamber
The necessity of a wireless system test has risen by the spread of recent wireless telecommunication equipment as shown in cellular phone, wireless LAN, RF-ID tag and ETC (Electronic Toll Collection system). It is necessary for a wireless test to be performed in anechoic environment in which an external noise is intercepted and a radio wave does not reflect internally. An anechoic chamber (room version of a shield box) is proper facilities but needs a wide space and a huge cost. Especially, the equipment under wireless system test on the production line can not radiate any signal radio wave outside before approval. The shield box satisfies these conditions.

Anechoic Chamber
Wedge:The acoustic absorptivity of sound-absorbing materials used in anechoic chamber must be greater than 0.99. In anechoic chamber, gradient absorption layer, wedge or conical structure are often applied with glass wool and flexible foam as its sound-absorging materials. Anechoic Door: The design of rotatable door can affect the whole function of anechoic chamber. Therefore, it's crucial to combine steel plate and sound-absorbing cotton in the door, which is exactly our design.Acoustic Insulating Material:Applying high-density materials to enclose external noise. Damping materials: Using spring, rubber and cotton to enhance damping capacity.The Anechoic Chamber conforms to GB/T 6882-86 and ISO 3745 specifications.

Anechoic chambers
The anechoic chambers are built up as a modular construction. Due to individual modules any size of chamber can be manufactured. Big chambers may require an outer supporting structure or alternatively the shielding material can be attached direct to the building. The absorbers are fixed to rails bars or wooden base construction which is inserted into the shielding modules.

Large-size Hybrid Reverberation / Anechoic Chamber
F-Series
The F large-size hybrid Reverberation/Anechoic Chamber represents the most versatile OTA test system in the market today. With the same unique test features of their E Series RC counterparts, the F-Series can also test large form-factor devices under test (DUTs) like laptops, large TV sets, solar and trash compactors, drones, fridges or washing and vending machines, among others. With up to 16x16, 8DLCC and DUTs up to 2m and 500 kg including full-body phantoms in a turntable, the F Series also expands the frequency range down to cover 200 MHz up to 40 GHz frequency ranges and the test modes to include EMC, BS, small cell, eNodeB and Virtual Drive Testing over the air (VDT-OTA). In an again unheard-of feature, the F-Series is also reverse-convertible into an Anechoic chamber, allowing Far Field (FF) and Spherical Near Field (SNF) radiation patterns, efficiency and gain measurements and pre-5G testing of antennas and devices. Conversion from RC to AC or vice versa can be performed within half a day.
