On DSL, the sync rates in each direction should usually be readable from the modem; they are typically reported on the router's status page. The advertised rate is less reliable, to say the least.
On wireless links, all bets are off - even with stationary endpoints, link capacity varies wildly over time. This needs to be solved in the radio-modems.
If it's wifi, however, a link-rate-independent solution now exists for certain hardware, and there's nothing theoretically stopping something similar being put into future HardMAC implementations. If we get the choice of hardware, naturally we choose wisely.
