5.4 Cellular (3G WAN) Screen
3G (Third Generation) is a digital, packet-switched wireless technology. Bandwidth usage is
optimized as multiple users share the same channel and bandwidth is only allocated to users
when they send data. It allows fast transfer of voice and non-voice data and provides
broadband Internet access to mobile devices.
If the signal strength of a 3G network is too low, the 3G card may switch to an available 2.5G
or 2.75G network.
To change your LAN-Cell's 3G WAN settings, click NETWORK > WAN > Cellular.
" The actual data rate you obtain varies depending the 3G card you use, the
signal strength to the service provider’s base station, etc.
1 Turn the LAN-Cell off before you install or remove a 3G card.
" The WAN and Cellular IP addresses of the LAN-Cell must be on different
subnets.
" The WIRELESS > CELLULAR menu in the Navigation Panel is a short-cut
directly to the Cellular WAN parameter screen (Figure 58 on page 115).
