At
what speeds can I get wireless?
The following are speeds at which you can get wireless.
They vary by which network you are on:
GSM: (Global System for Mobile Communication)
data transmitted at speeds up to 9.6Kbps
GPRS: (General Packet Radio Service) a 2.5G technology,
bursts data in
packets at speeds around around 30 to 40Kbps and up
to 56Kbps
1xRTT: Single carrier (1x) Radio Transmission
Technology, an evolution of CDMA, provides greater network
capacity and packet-switched data transmissions at 40
to 60Kbps and up to 144Kbps.
CDPD: (Cellular Digital Packet Data) also called
wireless IP, enables 19.2Kbps transmission rates.

What
are the differences between the different wireless networks?
•
GSM: This stands for global system for
mobile communications, and is the standard transmission
and reception technology used for wireless phones in
Europe and much of the rest of the world outside the
U.S. Most countries, logically, decided to pick a single,
standard wireless phone technology years ago, and they
settled on GSM. The U.S., incredibly, refused to settle
on a standard and that blunder has resulted in a patchwork
of multiple, incompatible technologies. The result has
been better and more innovative wireless phones and
wireless services in Europe than in the U.S.
GSM exists in the U.S., and is gaining ground here,
though it is broadcast on a different frequency than
the system used in Europe. It is used by companies including
VoiceStream, Cingular and AT&T, which is in the
process of converting its network to GSM.
• CDMA: The most widespread of the three main
wireless phone technologies used in the U.S., it stands
for code-division multiple access, and is the system
used by Verizon and Sprint.
• TDMA: This stands for time-division multiple
access, and is the third of the three major U.S. wireless
technologies. It has been mainly used by AT&T, which
is abandoning it for GSM.
These are the current systems in the
U.S. The following terms, describing future technologies,
have a lot more hype surrounding them.
• 3G: This is the Holy Grail of
wireless systems, a new "third-generation"
standard that supposedly allows for high-speed, always-on
data transmission and reception. It promises to handle
e-mail, instant messaging and Web browsing as smoothly
as current wired technologies. It is supposed to be
able to transmit data at speeds up to two megabits a
second -- faster than most home DSL and cable-modem
connections. But many 3G tests have been disappointing,
and phone carriers are having trouble getting it off
the ground.
• 2.5G: This is an interim step toward 3G, and
is arriving in the U.S. this year. It supposedly gets
peak data speeds of 144 kilobits per second, more than
double the speed of a home dial-up modem and much faster
than the data speed of about 10 kbps achieved by current
wireless phones. But most users, most of the time, will
see much lower speeds of around 50 kbps, which is about
as fast as a home dial-up modem.
• GPRS: This is the name for the 2.5G system that
will work on GSM phone networks. It stands for general
packet radio service.
• 1xRTT: Sometimes known as CDMA2000 1x, this
is the CDMA operators' 2.5G technology -- their answer
to GPRS.
These wireless technologies are all
for wide-area networks, like cellphone systems, that
must stretch for miles. But there are two very important
local-area, or short-range, wireless technologies that
are already here and are likely to become more common
and vital in coming years.
• Wi-Fi: This is one of the two,
a wireless networking technology for PCs and PDAs
that allows multiple devices to share a single high-speed
Internet connection over a distance of about 300 feet.
It can also be used to network a group of PCs without
wires. Wi-Fi is spreading like wildfire in homes, offices
and public places such as Starbucks coffee shops, hotels
and airports.
If you walk into one of these Wi-Fi-equipped places
with a properly equipped PC or PDA, you can quickly
be on the Internet at true broadband speeds, as if you
were connected by wire to a DSL line or cable modem.
Wi-Fi is very fast. It can transmit data at speeds of
up to 11 megabits per second.
• Wi-Fi 5: A new version of Wi-Fi that's even
faster, with a maximum speed of 54 megabits per second.
• 802.11b: The old techie name for Wi-Fi. (The
techie name for the new Wi-Fi 5 is 802.11a.)
• Bluetooth: The other short-range wireless technology;
it replaces cables over very short distances -- roughly
30 feet or less. Bluetooth, slower than Wi-Fi at about
one megabit per second, is designed to link a cellphone
to a laptop, or a PDA to a cellphone, or a laptop to
a printer -- all without cables

What
is Bluetooth? How does it work?
Bluetooth is a short-range (usually 30 feet or less)
wireless technology that replaces cables between two
Bluetooth-enabled devices such as a cell phone and a
notebook, a PDA and a cell phone, cell phone and a headset,
or a notebook and a printer.

Bluetooth glossary.

What
is 802.11b? How does it work?
802.11b, also known as Wi-Fi, is a wireless networking
technology that allows for multiple PDA devices to share
a single high-speed Internet connection over a distance
of about 300 feet by using an Access Point. Wi-Fi connections
are very fast, operating at speeds of up to 11 megabits
per second.
