IEEE 802.11 Standard Features Testing

Abstract

Over the last ten years, wireless local and personal area networks (WLAN/WPAN) have proliferated in the home, business, and public access areas. Because of the current market's wide range of WLAN products, a LAN/PAN interface is soon becoming as common as a standard Ethernet or USB connector. The IEEE 802.11 technology, which operates in both the 2.4 GHz and 5 GHz UNII bands and is known as Wi-Fi, has achieved tremendous global success. Due to these, it is important to test Wi-Fi devices before it reaches users. Testing like EU Adaptivity or RvR verifies that Wi-Fi SoC satisfies all the norms defined by the IEEE 802.11 Standards, so SoC will get certification from the LAB to use as a product. EU Adaptivity Test confirms the ability of the Wi-Fi SoC, to hold off transmission when an interfering signal is present. Meeting this requirement proves the Wi-Fi SoC can safely share the spectrum with other users. RvR Test confirms the ability of the Wi-Fi SoC, and how wireless throughput changes as path loss (signal level) changes between the DUT and a standard test companion device. Meeting this requirement proves the Wi-Fi SoC satisfies all the norms defined by the IEEE 802.11 Standards. After satisfying the IEEE 802.11 Standards norms then only Wi-Fi SoC will get certification from the LAB to use as a product. Here the performance evaluation of range & data rate is achieved by IEEE 802.11 a/an/ac/ax with all supported bandwidths based on various parameters like Modulation Techniques used, Code Rate, supported Modulation Coding Scheme (MCS) Index, respective Tx Power, and Received Signal Strength Indicator (RSSI) Value supported by each configuration is carried out in the shielded environment.
