Cellular Tracking 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 available.

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 Devices?

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 approved carriers.

How do I select a cellular data plan for cellular tracking?


Very carefully!


The 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. 

  • CES Wireless will process the paperwork to activate our products on these networks on your behalf, eliminating extra steps for you.
