• Technical Brief - Verifying 802.11n Access Points  - The emerging 802.11n standard brings a new level of functionality and performance to the world of Wireless LAN. Components are becoming available and are being designed into Access Points in both consumer and enterprise network equipment. The ability for a chipset design to perform the 802.11a/b/g legacy functions is not a given. To meet the demanding requirements of 802.11n, the components and drivers have been substantially changed from earlier chipset designs. This means that the verification of all features, modes and functions set forth by the 802.11a/b/g sections of the standard must be performed on the Access Point and associated WLAN controller. In previous generations of product development, this has been a difficult, time-consuming and hard-to-replicate task. With the availability of the IxVeriWave WaveTest system, this task can be accomplished in a fraction of the time with the precision, repeatability and automation support expected of test-grade system solutions. Legacy qualification of Access Point designs can be accomplished with more confidence and speed than ever before.
