performance and number-of-stations capacity. It allows a user to fine-tune sys-
tem parameters to maximize performance during testing.
The differences between IxWLAN and other IP load generators can be summa-
rized as follows:
• IP-based Load Generators are per-station devices that do not reduce the num-
ber of PCs and station NIC cards. You can configure only one IP per station
and then send traffic.
• IxWLAN allows all stations to be emulated on a single platform and radio
chipset, thus reducing the cost and complexity of multiple PCs.
IxWLAN creates Virtual Stations (vSTAs) and generates or passes traffic that
loads and stress tests Wireless LAN and 802.11 products in terms of:
• Frame performance
• Number-of-stations capacity
• Scalability
• WLAN optimization
Because a single physical 802.11a/b/g emulator emulates multiple vSTAs, it
reduces the number of PC and station NIC cards that are needed to test and stage
802.11 products and wireless LANs.
As of 6.20 version, IxWLAN is supported by two chassis, the IxWLAN SED and
the IxWLAN SED-MR+.
