Evaluation Hardware or Software

LANforge WiFire - 802.11 a,b,g,n and ac - wireless network traffic generator

 

The LANforge WiFire appliance is an excellent choice for testing Access Points and other WiFi networks.

 

The WiFire uses a modified Wireless driver for WiFi NICs based on the Atheros chipsets. Depending on the appliance configuration, a single appliance can support from 32 Virtual Stations to 600 Virtual Stations (Up to 200 per radio). Each of the Virtual Stations has its own IP address, IP port space, MAC address and routing table. The Virtual Stations may be configured with all of the virtual interfaces on the same subnet, or different subnets, depending on the testing requirements.

 

The Virtual Stations can be assigned to communicate to a particular Access Point, use a particular ESSID and Nickname, and have a WEP (64 or 128bit) or WPA key assigned. Multiple systems can be clustered together for even more realistic radio interference patterns and increased traffic generation capability. Each radio can be configured independently of the other, and supports 802.11 a, b, g n or ac mode. The radio's channel, frequency, sensitivity, rate, RTS and Tx-Power can also be configured.

 

All virtual stations on the same radio must be on the same frequency, but as long as the protocol supports that fequency, the multiple protocols can be used concurrently. For instance, if the radio is configured for a 2.4Ghz channel, the stations can be /b, /g, /n, or /ac. If the radio is on a 5Ghz channel, the stations can be /a, /n or /ac. The bandwidth can be configured for all protocols. For 802.11n, configuring the MCS rates also determines the number of streams (1x1, 2x2, 3x3, etc.).

 

LANforge RF Attenuator

 

Optionaly available is the LANforge RF Attenuator - this device can be used with LANforge Wi-Fire to attenuate (decrease) the RF signal between wireless devices. Get more information on attenuator

Traffic Generation and Features

LANforge WiFIRE can generate FTP, HTTP, VoIP (SIP, RTP, RTCP), TCP/IP, UDP/IP, Ethernet and custom payloads. It supports 802.1Q VLANs, and can also emulate hundreds of Ethernet interfaces with unique MAC and IP addresses, allowing a single LANforge machine to appear as an entire subnet of machines. LANforge run on Windows or Linux, with the most extensive feature set running on Linux. Click for a summary of traffic types or a full listing of features.

NIC Radio descriptions and Virtual Stations Supported

 

The WiFire uses a modified Wireless driver for the Atheros ath9k (a/b/g/n) chipset NICs and can support up to 200 stations per radio. Depending on the appliance configuration, a single appliance can support from 32 Virtual Stations to 600 Virtual Stations (Up to 200 per radio). Each of the Virtual Stations has its own IP address, IP port space, MAC address and routing table. The Virtual Stations may be configured with all of the virtual interfaces on the same subnet, or different subnets, depending on the testing requirements.

 

LANforge support for 802.11 ac utilizes the Qualcom-Atheros (QCA) ath10k linux driver and modified firmware. The NIC supports 3x3 MIMO, up to 1.3Gbps encoding rates, and up to 64 virtual stations per radio. The ath9k and ath10k NICs can be mixed on a single appliance.
