1 WaveTest Multi-client Traffic Generatr/ Perfrmance Analyzer Highlights Autmatin 10x mre efficient Cst f wnership minimized Repeatability equals cnfidence Ges beynd cnfrmance and interperability Pwerful WaveTest Traffic Generatr / Analyzers are capable f generating thusands f independent client sessins, each representing a unique user f the netwrk. Traffic can be accurately, repeatedly, and precisely created t assess perfrmance in real-wrld cnditins at scale. WaveTest delivers unique insight int the functinality, quality and perfrmance f the netwrk, r netwrk cmpnent, under test. The slutin features native IEEE a/b/g/n/ac interfaces as well as 10/100/1000 Mbps Ethernet interfaces. Figure 1: WaveTest 92 and Agura Rad Calabasas, CA USA Tel Dcument N.: Rev F May Page 1

The plan utlines the gals, prcedures, and expected results fr thusands f unique test cases while ffering insight int the behavir and perfrmance f wireless LANs. The Master Test Plan ffers the flexibility f selectively chsing the mst apprpriate individual tests needed t verify the functinality and perfrmance f each unique system under test. The guide addresses every aspect f required netwrk testing, frm functinal verificatin, perfrmance measurement, and netwrk capacity assessment t system testing and stress testing. Large-scale Testing WaveTest is a chassis-based test system that utilizes individual WaveBlades fr traffic generatin and analysis: Each WaveBlade supprts up t 4 independent traffic generatr / perfrmance analyzers Each WaveBlade traffic generatr / perfrmance analyzer emulates up t 500 WLAN r 1,000 Ethernet clients acrss single r multiple subnets Gigabit Ethernet traffic generatin and analysis at full wire-speed Each WaveTest 92 supprts up t 8 WaveBlades with an Ethernet Blades prviding a cmbined capacity f 16,000 individual WLAN clients (STAs) Traffic generated and analyzed between WLAN clients and Ethernet clients / servers r mbile WLAN clients Multiple traffic flws per client supprted with each flw ffering stateful traffic at layers 1 r 2 thrugh 7 Real-time prt statistics, per flw statistics, packet filters, triggers, and capture capabilities fr precise analysis Built-in client mbility allws precise raming f each and every client between any access pints (APs) at predetermined time r pwer settings Page 2
