With the introduction of 802.11n and it's advantages over previous WLAN standards, more and more customers are now looking to deploy real-time applications on the WLAN, such as voice and video. Although the 802.11n provides a good basis to do so, it is important to understand that there are other important aspects that need to be considered, such as vendor-specific implementations of QoS and multicast support. Motorola Product Marketing has published a very interesting clip on YouTube, showing the differences between Motorola and Cisco WLAN handling real-time streaming video. It clearly shows that not every 802.11n network has the same quality when it comes down to support of real-time applications.
