chipset.
.Pp
+The RT2500 chipset consists of two integrated chips, a RT2560 MAC/BBP and a
+radio transceiver (the model of which depends on the card revision).
+.Pp
+The RT2522, RT2523, RT2524, RT2525, RT2525e radio transceivers operate in
+the 2.4GHz band (802.11b/g) whereas the RT5222 is a dual-band radio
+transceiver that can operate in the 2.4GHz and 5.2GHz bands (802.11a).
+.Pp
+The transmit speed is user-selectable or can be adapted automatically by the
+driver depending on the received-signal strength. See
