1. An IEEE 802.11 compliant wireless local area network (WLAN) multiprotocol device comprising:
one frequency band agile, complementary code keying (CCK) and orthogonal frequency division multiplex (OFDM) modulation-capable radio;
a data flow structure framework which organizes and routes transmitted and received data packets within the multiprotocol device; and
a medium access control (MAC) mechanism which wirelessly exchanges the data packets between the multiprotocol device and other IEEE 802.11 compliant devices,
wherein the device is capable of engaging in simultaneous distinct channel IEEE 802.11a, 802.11b and 802.11g communications.
