Willtek’s 4921 Shield Box is a new RF shielding solution for testing 3G mobile phones, as well as data cards and WLAN equipment in large service centres and production lines. The 4921 is the optimum solution for service centres and manufacturers with high volume phone testing because it can endure the high open/close rates involved. The RF Shield is designed to eliminate interference from any adjacent mobile phones, the local base station, and to isolate the environment from the RF emitted from the phone (or other device under test).
Stringent Shielding Requirements for 3G Mobile Phone Testing
Most third-generation (3G) mobile phone systems are based on CDMA technology, which puts new demands on test environments. The 4921 easily fulfils the 80 dB attenuation requirement for testing mobile phones for UMTS and other third-generation wireless networks. The RF absorption inside the 4921 leads to low reflection within the box, thereby providing high-precision, stable RF measurement results with instruments connected to it. The 4921 is the first of its kind to meet all the service, repair and manufacturing requirements in terms of attenuation, longevity, dimensions, and price |
