Laptop users typically access the Internet via Wi-Fi and a nearby
hotspot or access point. Alternatively, they may have a plug-in USB
device or PC card for GSM/EDGE/WCDMA or CDMA. Soon, they also
will be able to get embedded Internet access and e-mail from any of
their nearby 3G cellular services thanks to Qualcomm’s Gobi system.
Mixing Qualcomm’s MDM1000 chip set, related software, and APIs,
Gobi supports the most popular and available 3G data services. These
include cdma2000 EV-DO with Rev. A as well as UMTS WCDMA plus
HSDPA/HSUPA and EDGE. It supports all four popular cellular bands.
Gobi also includes receive diversity and power management.
While most laptops will continue to include Wi-Fi, this embedded
option gives laptop owners a wider choice of wireless suppliers, longer
range, and worldwide coverage. The chip set accelerates Internet
access and makes mobile TV, music downloads, and gaming possible
from almost anywhere. Its built-in GPS capability makes all sorts of
location-based services possible as well.
More and more laptop manufacturers are moving to embedded wireless
capability rather than USB or PC card plug-ins. By covering both
types of 3G networks, Gobi eliminates compromised coverage and carrier
choice decisions. And with the potential competition from embedded
WiMAX in laptops coming soon, Qualcomm is supplying an additional
alternative for full wireless access via available 3G services.
