Answer 2

The connection between a Blackberry and the BES can be carried over the wireless carrier network, to the internet, to the RIM operations centre then by the internet to the BES; or by Wi-Fi to the internet to RIM to the internet to the BES; or by Wi-Fi directly to the BES (if the BES is local to the Wi-Fi connection); or by USB to a PC with Desktop Manager via the local area network to the BES.
