C. SAVE m-learning Architecture
The SAVE m-learning application architecture is divided
in to two main parts; the server side and the client side. The
communication flow is shown in Fig. 4, between the client
side consisting of the handheld devices and the laptop server
in the MoVE unit, which communicate using the Wi-Fi LAN
connectivity established between them. The laptop server is
linked using CDMA or 3G wireless Internet to the remote
main server, which accesses and processes requests made to it
from the client-side.
