It uses a hybrid of OFDM for slow data rates and CCK for fast data rates allowing both waveforms to coexist on the same WLAN.

It uses the CCK waveform which offers much higher speeds, greater ranges, and better tolerance of multipath echoes which are common to internal building applications.

It provides interoperability between 5.5 Mbps and 54 Mbps WLAN speeds at 5 GHz thus allowing for compatibility with legacy systems and new devices.

It provides interoperability among and between all WLAN speeds working at the 2.4 GHz frequency eliminating the need for a complete equipment upgrade.
