WLAN Rx PER Test Implementation in ATE

With the advert invention of wireless fidelity commonly called as Wi-Fi in the field of communication and computer networks a new era or revolution has taken place. In the recent twenty years, numerous IEEE 802.11 technologies have been developed for Wireless Local Area Network (WLAN) connectivity. The common point of these technologies is that the latest IEEE 802.11 version has always several advanced features compared to its predecessor. Simultaneously, testing this technology standard parameter is a challenge in the ATE production environment. One of the key standard parameters in radio receiver specification is Packet Error Rate (PER) which is a direct measurement of field parameter. In this paper, a detailed implementation of WLAN Rx PER test in Production Automated Test Equipment (ATE) environment with parallel testing is described and studied. This study incorporates efficiency of implementation, yield improvement of 2% and test time comparison with respect to legacy test methodology.
