发帖数: 241 | 3 frame burst真的有这么管用？这个frame burst是不是就是对一个超长的packet进行
fragment然后每两个burst frame之间不用LIFS，只用SIFS？所以只要一个frame竞争上
信道之后，其后所有的frame都可以传输了

a big portion of time in 802.11 MAC protocol is
wasted on catching the channel (random-backoff).

CA的

throughput分析的文章里面间接得到答案。
只要看看average interframe timeslot number vs. node
number 就可以得出大概的结论。理想情况下，frame burst
模式可以eliminate这些waste。

this technology. The clients can be normal ones.
