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 Filters
RF leakage through Ethernet and USB cables can destroy even the best RF enclosures and chambers. The need for filtering in the ever congested RF environment requires special filters that can pass USB 2.0 and 10/100/1000 Mbps Ethernet signals and filter out unwanted higher frequencies such as cellular and WiFi. The Adaura Technologies USB/Gigabit Filters provide one GigE and one USB 2.0 pass-through connections while filtering out other RF up to 8GHz. It has a small form factor to allow easy installation. It is a most cost effective solution for a clean chamber set up. In a typical chamber, WiFi signals are reduced to <-100dBm with this filter installed.

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.

Tapered Anechoic Chamber
It’s nearly impossible to perform VHF/UHF measurements in a rectangular chamber. In the 1960’s Emerson determined that tapering one end of an Anechoic Chamber would cause the chamber to act like an indoor ground reflection range.Tapered Chambers work very well at the lower frequencies. Their design forms a uniform illumination across the test region. The tapered end of the chamber forces the wall images close together forming a source antenna array. Tapered Chambers are usually a less expensive option compared to rectangular antenna measurement chambers or compact ranges.
