这道题目看似是和 voice over wlan 有关，所以应该选D.

同學您好！我們討論一下。剛剛查了一下，底下的連結中，Target Environmental Characteristics for WLANs in Higher Education Environments標題下的內容應該可以提供你在這題中需要知道的答案。

. @1 i$ e5 d; o# |( a! |" m9 R  CIn a high-density environment such as a lecture hall or auditorium, the densities of users in the occupied space increase dramatically. User seating is typically clustered very close together to achieve high occupancy. The overall dimensions of the space are really only useful for getting an idea of the free space path loss of the AP signal. User densities are not evenly distributed over the entire space as aisle ways, stages, and podiums represent a percentage of space which is relatively unoccupied. The RF dynamics of the AP are very different from those experienced at the user level. The APs are exposed with an excellent view of the room and the user devices will be packed closely together with attenuating bodies surrounding them.

" }: |" J' T4 W, a. s3 QThe single biggest sources of interference in the room are the client devices themselves. For each user sitting in the auditorium who can rest their hand comfortably on the back of the seat in front of them, the distance is approximately three feet, with an average seat width of 24 inches. This yields what is defined as a high-density environment, with less than 1 square meter per device deployed, assuming one or more devices connected per seat.

而題目中表明了有五百個學生與他們的筆電，如此高數量的末端使用者數量符合上述的資訊，所以我認為本題的答案應該是High-density design model才對。您認為呢？
