Understand and Make the
Most of a
Wireless Network Connection with Us
Maybe
you want a
cellular wireless phone for your
computing mobile needs. Not only can
eAccess Solutions help you with
your
wireless network connection, but we can also assist you in
understanding the technology that goes into meeting
computing mobile requirements.
Wireless Data
technologies in use today can be broken down into the three topologies
listed below. These topologies can be used individually or, in some cases,
networked together to provide the desired coverage. To get an idea of the
network configurations, devices and area coverage, click on the technology
to view more information. Need more information about a
cellular wireless phone or other topics? Try our

Wireless Data 101
A Simple Explanation of Where We
Are Today |
"eAccess is
one of the few places that customers can get a true, unbiased comparison of
network carriers because we work with them all!"
- David Bean, CEO eAccess
Solutions, Inc. |
To understand where wireless data is at and is going, you need to know a
little bit about where we have been. Here in the USA there are two
competing standards. The first is CDMA which evolved from the first
analog cellular service ever offered. The second is GSM which was the
first digital cellular service offered. GSM is by leaps and bounds the
most accepted standard the world over so GSM data devices will work not only
in the US but also in most countries overseas. CDMA is is a technology
that is primarily used in the USA only with very few exceptions.
Here is how the wireless carriers that
eAccess partners with break out:
| Cellular Provider |
Cellular Technology |
| Cingular |
GSM |
| Nextel |
GSM/iDen |
| Sprint |
CDMA |
| T-Mobile |
GSM |
| Verizon |
CDMA |
One of the first characteristics you may hear about
wireless data is something like 2G or 3G and how that 3G is better. Let me
explain what this means. The G referred to here is a generic term related to
the generation of wireless that a carrier is offering. So there currently
are 3 generations of wireless commonly referred to as 1G, 2G and 3G.
Occasionally some vendors will refer to intermediate increases in
performance as 2.5G.
This table explains what type of cellular data is applicable to the
generation of wireless:
| Generation |
CDMA Carriers |
CDMA Speed |
GSM Carriers |
GSM Speed |
| 1G |
Analog
(Discontinued) |
19.2Kbps |
none |
N/A |
| 2G |
1xRTT |
128Kbps |
GPRS |
40Kbps |
| 2.5G |
1xRTT |
128Kbps |
EDGE |
160Kbps |
| 3G |
EvDO |
500-700Kbps |
UMTS (WCDMA) |
2,000Kbps |
The carriers have chosen quick phrases like
1xRTT, EvDO, GPRS, EDGE and UMTS to make it easy for a user to refer to the
type of data services they offer. Here is a quick table with the meanings of
those acronyms. For more information
check out our
Wireless Glossary.
| Abbreviation |
Meaning |
| GPRS |
General
Packet Radio Service |
| EDGE |
Enhanced Data rates for
GSM Evolution |
| 1xRTT |
Single
Carrier (1x) Radio Transmission Technology |
| EVDO |
Evolution Data Only,
Evolution Data Optimized |
| UMTS |
Universal Mobile Telecommunications System |
You now have a better idea what types of data services the
carriers can offer. However each carrier has made their own decisions
regarding what data services they offer. Here is a table of the current data
offerings by carrier:
|
CDMA Carrier |
2G Technology |
3G Technology |

Sprint |
1xRTT |
EvDO |

What's the Difference
Between PAN. WLAN and WAN Wireless Technologies? |
PAN (Personal Area Network) - Infrared,
Bluetooth
Infrared can be used to print or send files when the two devices are less than
a few feet a part at speeds of over 115kbs. Bluetooth is
an
emerging technology that will let you connect
your mobile device to your cell or digital phone at speeds up to 720kbs when
it is less than 10 meters away. |
 |
| WLAN (Wireless Local Area Network) - Wireless
Ethernet
Wireless Ethernet is comprised mainly today of the
802.11b
standard that can connect you at speeds of up to 11mbs within a few hundred
feet of the access point. Recently 802.11a has
become available and offers speeds up to 53mbs. 802.11g
offers that same 53mbs speed but is also
be backwards compatible with 802.11b
technology.
|
 |
WAN (Wide Area Network) - Wireless Data
Network Subscriptions
Mobitex, DataTAC, AMPS, CDPD,
iDEN, Reflex,
CDMA, TDMA, GSM, GPRS,
LEOS and 1xRTT. Speeds vary on these networks from
8kbs to 70kbs but nationwide coverage is very good. |

Beyond!
