“The Wireshark/AirPcap 802.11n solution
provided by CACE Technologies is a fundamental
tool in Intel’s 802.11n protocol testing and
evaluation. Along with outstanding 802.11n
protocol support, the physical layer information
reported on a per-packet basis, such as noise
and signal modulation, has proved invaluable.
CACE’s use of open source tools will ease sharing
of information between Intel and our customers
and competitors, which has been a long-standing
issue during the extended 802.11n Draft process.
CACE’s quick delivery of a stable and feature-
rich product is an outstanding example of quality
software development and customer orientation.”
