Willtek 4921 Overview
Willtek’s 4921 RF Shield 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).
