wow, there's alot wrong with this question because the
assumption is incorrect.
802.11a and 802.11b are incompatible standards. the
802.11a standard is not simply a "lower" standard than
802.11b.
The 802.11b standard wireless radio generates a
2.4-GHz carrier wave (2.4 to 2.483 GHz) and modulates
that wave using a variety of techniques. The current
802.11b standard already defines the basic rates of
1, 2, 5.5 and 11 Mbit/s.

The 802.11a standard, operates at the 5-GHz UNII
(unlicensed National Information Infrastructure) band
and can achieve data rates as high as 54 Mbits/s. This
standard as well as the next upcoming 802.11g are not
widely adopted. (some credit multi-pathing as the
reason for the reluctance...)

So, as you can see, If your base station is a 2Mbps
system, most likely is it either an 802.11b or some
derivative thereof...Or it might be a proprietary
system. If that's the case, then it will be completly
incompatible...as would an 802.11a system!
