Wireless wide area network (WWAN) devices provide access to information anytime and anywhere that you have cellular (data) coverage. In a WWAN, each mobile device communicates to a public carrier’s base station. Public carriers install networks of base stations (similar to cell phone towers) throughout large geographic areas, effectively providing coverage across entire states, or even entire countries/ regions.

Connecting the Wireless LAN Device(Select models only)
You can connect the computer to an 802.11n (select models only), 802.11b or 802.11g wireless network by using the external antenna that was included with the system. This device enables you to establish a wireless network using the computer as a wireless access point, or you can use the computer as a wireless client (Station Mode) if you already have a wireless network running.
You need an existing wireless LAN with an Internet connection (consult your Internet Service Provider for further information). An external antenna is supplied with the system; you must connect it to the 802.11 module to increase the range and sensitivity of
the radio.
To connect the wireless LAN antenna:
1Screw the wireless LAN antenna
cable into the wireless LAN connector on the back of the computer.
2 For the best wireless performance, place the antenna on the computer or in an elevated and open area.
NOTE: The appearance of your wireless antenna may vary.
