If you decided
that was the best option for you, either because that is the only way you can get
to the Internet at home or because you prefer a cellular data connection when
you??™re on the road, this project will help you kick it up another notch and share that
connection with other computers. By employing a mobile router, such as the Kyocera
KR1 Mobile Router or a similar unit from Linksys or Top Global, you can expand your
cellular connection to other computers easily by Ethernet cable or Wi-Fi??”at home or
when mobile. In this project, we??™re creating an expanded cellular data Internet configuration
that will look like Figure 16-1.
A mobile router can use either the tethered cellular modem Internet access from
your cell phone or a PC Card plugged into the router. From there the router acts like
any other broadband router/firewall with Wi-Fi access. The details we??™ve covered in
previous projects for routers and firewalls give us a good foundation to build on??”
substituting cellular for cable or DSL. An advantage of cellular connectivity over Wi-Fi

is that it is designed to work on-the-move, so if someone you??™re traveling with needs
to be connected, cellular is the best option available.
Step 1: Set Up the Mobile Router
This project starts with a Kyocera KR1 Mobile Router, shown in Figure 16-2. This
router accepts an EVDO (Verizon or Sprint) cellular modem PC Card or USB-tethered
data-capable cell phone (of which only a few models are supported so far) as the
Wireless Wide Area Network (WWAN) Internet connection.
