I'd like to know if there is any information about slot synchronization of
current off-the-shelf cards. Ideally, a station should issue transmissions
on slot boundary, but some material has shown that this does not hold for
all the products (e.g. The Infocom 07 paper, entitled as
<http://www.tti.unipa.it/~ilenia/pub/info07.pdf> "Experimental assessment of
the backoff behavior of commercial IEEE 802.11b network cards"). The thing
is I need more detailed result about "to what degree they are not
synchronized". I appreciate if anyone can share some info on this.
