Before revision:  We first  establish that the so-called mean field technique, which spins off a fixed point equation, is mathematically valid for use in performance analysis of 802.11. On the basis of this , succinct equations describing the backoff distribution as a function of the collision probability \gamma are derived .
After revision:  We first  establish make a simplistic Palm interpretation of the Bianchi's formula and on the basis of which , succinct equations describing the backoff distribution as a function of the collision probability \gamma are derived .
