CDMA Tracker


If your business requires fleet tracking, you need a convenient and seamless way to track every car, truck, and van in the company. GPS technology provides that functionality, but the acronyms and competing standards can make choosing a fleet tracking technology difficult.

For fleet tracking purposes, there are two main competing standards – GSM (global system for mobiles) and CDMA (code division multiple access). At the moment GSM has the biggest market share, but that is starting to change as fleet owners are drawn to the greater security, enhanced flexibility and superior encryption that CDMA trackers can provide.

CDMA fleet tracking technology uses a spread spectrum technique to provide its tracking results. This spread spectrum technology spreads electromagnetic energy to give the signal a wider bandwidth. This spread spectrum technology allows multiple individuals on multiple cell phones to use the same channel and share the same bandwidth. This multiplexing allows CDMA to operate at maximum efficiency without compromising quality or accuracy.

CDMA trackers separate data and voice packets through the use of codes. Those separate data and voice packets are then transmitted through a wide frequency range. With CDMA more space is allocated for data, making the standard particularly attractive for high-speed mobile Internet uses.

While it is most often associated with fleet tracking technology, the CDMA standard was originally designed by Qualcomm. It is currently used widely used throughout the United States and in parts of Asia. Most U.S. cell phone carriers have adopted the CDMA standard, including such heavy hitters as Verizon, Sprint and Virgin Mobile.

While GSM provides more extensive coverage outside the United States, CDMA is often the superior standard for use within the U.S. and Canada. The superior coverage CDMA provides throughout the U.S. and Canada means better location accuracy, enhanced security and a host of other benefits for fleet managers.
