MLPPP for WiFi

Hi Guys,
Sorry that this mesg is posted in english.

I browse this forum almost everyday... Just wanted to ask something quick, as I am seeing quite a lot of "high-hand" over here.

For Wi-Fi, can I do something like MLPPP(Multi-Link PPP)? the situation is, there are two offices(on different buildings, but just next to each other) that are connected via wireless connection, and they need high bandwidth for business needs.

I am wondering if there is any solution that use a few WiFi Access Points to do bundled tunneling to acheive higher bandwidth, just like what we do for ISDN or Dialup...

It will be great if any kind soul can help to do the translation so that more forum user can share his/her idea.... For such messege, if I were to use chinese char, it will at least take me 1 hour to type it in...

谢谢！！！
