Network Mode
Strengths
No need for chipset vendor “control software”
Test WLAN devices in “real world” conditions
Automated receiver sensitivity traces
Simplest and fastest test configuration
Weaknesses
DUT must have functional baseband
Security and Firewalls must be disabled
Network Typically Ethernet Access Point Laptop (STA) Laptop Laptop Laptop (STA) MT8860B can simulate an Access Point (AP) or Client (STA) Laptop Laptop MT8860B in an Ad-Hoc connection Slide 16 Anritsu Confidential Information – For internal use only
