Using the 3G Feature (Optional)
NOTE:
To take advantage of the 3G feature, the 3G driver (includes the software
application) supplied with your computer must be installed. (See chapter 6 for details.)
3G is the third generation of mobile phone standards and technology,
after 2G. It is based on the International Telecommunication Union (ITU)
family of standards under the International Mobile Telecommunications
programme, “IMT-2000”. Services include wide-area wireless voice
telephony and broadband wireless data, all in a mobile environment.
Unlike IEEE 802.11 networks, 3G networks are
wide area cellular
telephone networks
which evolved to incorporate high-speed internet
access and video telephony. IEEE 802.11 networks are short range,
high-bandwidth networks primarily developed for data.
To use the 3G feature on your computer, you need to subscribe to 3G
service and install the 3G SIM card from your service provider, network
operator, or other vendor.
To install the SIM card, follow these steps:
1.
Make sure that the computer is not turned on or connected to AC
power.
2.
Place the computer upside down.
3.
Slide the battery security lock outward to the unlock ( ) position
(
).
