Guide - GSM/GPRS, 1XRTT, EVDO, HESPA, CDMA
Cellular is a very reliable and efficient means of communicating
with your mobile work force. Most major markets and highways
have excellent coverage. The only downside, the cost of a
monthly data plan.
Cellular data devices are
currently available in two forms; GSM/GPRS and CDMA (sometimes
also referred to as 1xRTT or EVDO). In the USA, T-Mobile
and AT&T are GSM/GPRS based, and Verizon and Sprint networks use
CDMA. Decide which carrier is best for you based on the coverage
GSM/GPRS provides speeds up
to 80 Kbps, with CMDA, data speeds are about 144 Kbps. Service
must be purchased from a service provider (CES Wireless) or
cellular carrier (T-Mobile, Cingular, Sprint or Verizon) The
process is very similar to a voice plan, but with data the
cost is based on the amount of data transferred, measured in
megabytes (Mb) (see below for explanation).
A 5 Mb per vehicle per month plan is sufficient for most
applications. The good news, you do not have to worry about this
since CES GPS Tracking products ship already provisioned and
active on the carrier of choice, if you wish.
What coverage is available for Cellular Tracking
This varies country by country. In
the USA, CES products will operate over the AT&T,
T-Mobile, Sprint or Verizon cellular networks. International
carriers either support GPRS and CDMA. Contact CES for a list of

amount of data sent is relatively low, and is viewed by the carriers as
a 'telemetry' application. Most carriers have a 5 Mb plan, but as you see
from the example below, a typical vehicle would come nowhere close to using
all of this available plan. You can however increase the vehicle location
update rate (programmable feature on all CES Wireless products).
Expect to pay from
US$12.00 to $25.00 per vehicle, per month for cellular data airtime
(bucket plans also negotiable).
Determine who is the
cellular carrier with the most reliable and best coverage in your area.
Ignore companies who
try and sell you a fleet management system using 'their" preferred
carrier. You will not have the flexibility to change carriers if service
deteriorates, rates can increase without you having any negotiating
power and your supplier will probably add a surcharge to the carrier
data airtime fee.
CES Wireless products
are compatible with GPRS and CDMA. These services are provided by AT&T, T
Mobile, Sprint and Verizon.

bit is short for binary digit, the smallest unit of information on a
computer machine that is used to represent plain language. A single
bit can hold only one of two values: 0 or 1.
Byte - A
byte is a unit of measure of 8 bits.
Kilobyte - A kilobyte is a unit of measure equal to 1024 bytes.
- A megabyte (1MB) is a unit of measure equal to 1,048,576 bytes or
