Wi-Fi is the de facto communication mode in homes, public areas, offices and in industrial sites.
To obtain highest performance of any Wi-Fi installment, precise control of the wireless network with provisions for debugging, access control and continuous monitoring for security has become relevant. Debugging and monitoring Wi-Fi networks requires a stable, reliable, technically advanced solution – the Wi-Fi packet monitor (sniffer) and packet probe tool (injector).
A Wi-Fi Sniffer is a device which will passively “listen” and “record” information exchanged in the particular Wi-Fi channel. A Wi-Fi Injector device is an active device which can be used to transmit data in a Wi-Fi channel and record/analyze the response for it’s action.
Intelligraphics developed a mobile Wi-Fi sniffer solution that utilizes the TI WiLink 6.0, WiLink 7.0 and WiLink 8.0 series mobile Wi-Fi chipsets (TI WL127x / WL128x/WL18xx) to create a truly portable Mobile Hardware Sniffer, featuring a single Wi-Fi driver that can either act as a Wi-Fi sniffer, or as a regular Wi-Fi driver.

► Support for filtering at type:
► Support for filtering at subtype:
► Infrastructure specific metadata on a per packet basis:
- Channel/Frequency info
- Length of underlying MAC frame
- RSSI (Signal Strength)
- Time Stamp
- Data Rate
► Availability of unprocessed frames with errors:
- PHY Errors
- CRC errors
► Ability to decode encrypted frames Intermediate buffering driver:
- The intermediate buffering driver is used to improve performance
- The buffering driver optimizes the bottleneck in processing between the Wi-Fi sniffer driver and the user application.
► API Interface for application development:
- Provides a well defined API that is used to control the sniffer
- The API interface makes it easy for application developers to interface their application to the sniffer.
► Support for multiple platforms:
- Torpedo DM3730 reference design
- Panda OMAP 4430 reference design
- OMAP4 Blaze platform 4430
- Commercial LG Thrill 3d smart phone
- Motorola Razer Maxx
- BeagleBone Black
- Can be ported to other platforms on a customer driven basis
► Support for Injection
- Full 802.11 packet content controllable by user includingRateLengthType of packetDuration
- Option to follow CSMA/CA protocol for Injection
- Overriding of CSMA/CA or Backoff protocol for Injection
► Type of solutions
- Driver + Firmware combo Sniffer
- Firmware only Sniffer solution (Can be utilized in devices where driver for Wireless chipset is not modifiable)
