The Bollen testcenter (STC) supports the most performance and authenticity of IEEE 802.11 Wireless LAN (WLAN) multi-client emulation, which performs direct functional and performance testing of the

access point (AP), and can Perform tests on WLAN ecosystems including WLAN access controllers and gateways. By adding one or more WLAN client emulation cards to the STC C1/C50 or n4u/n11u 

chassis, the user can simulate a large number of real 802.11 a/b/g/n/ac clients at 2.4GHz or 5GHz frequencies, and through wire transmission or air (OTA) link to the access point. The solution can 

support the basic WLAN control layer and data layer characteristics on WLAN network and the advanced IETF RFC network traffic and throughput performance test cases by simulating the client and  

the access point being tested.

Overview and Application

Overview

WLAN RF Interface Card (NIC) and the test module provided by each WLAN test port contains multiple IEEE 802.11 radio units, can provide users with maximum configuration and flexibility, can simulate a 2.4GHz or 5GHz band of multiple IEEE 802.11 clients. WLAN test port points to a series of MIMO RF ports, these MIMO RF ports are equipped with SMA connectors, can connect to the OTA link antenna, can also be connected to the wired conduction connection. A single WLAN test interface can support clients using different 802.11 protocol modes and spatial streams to achieve the best real-world client emulation scenario. Spirent Testcenter WLAN solutions are designed to test WLAN network infrastructure equipment, including thin access points with controllers in carriers or enterprises, consumer access points, and integrated broadband WLAN gateways. The solution can therefore provide the best flow generation and analysis capabilities at the same level, and is designed to test functionality, performance, and scalability.
