GPS Tracking Service Comparison: RF vs. Cellular

Common GPS vehicle tracking systems use “cellular” GSM/GPRS based transponders. Once the device calculates position from the GPS satellites the transponder transmits the position to the cellular GSM/GPRS network of receivers (cell towers) in the area.  At this point the GSM/GPRS system operator transports the data to your output device. Obviously the network operator charges a fee for this service, and is in control of your data as well.

Data Radio Modems

Wireless modems are used to send data between two or more locations. Raveon’s long range VHF data radios and UHF data radios are capable of communicating up to 100 miles, with typical distance in the 10-40 mile range. The data the Raveon modem communicates may be telemetry signals from a transducer, remote control signals, computer communications, GPS position, or a host of other digital messages. Various Input/Output connectors are available including USB, RS232, RS485, RS422, and digital logic levels. Raveon designs its data radio modems with 32-bit micro-processors enabling these products with more features and capabilities than most any other radio modem.

Guest Post: Missouri State University Campus Bus Tracking

By: Corbin Campbell, Electronics Support Services. Missouri State University

Just a little history, our Assistant Director of Public Safety had a project for me. Missouri State University had the ability to GPS track the shuttle bus fleet for the students, faculty, staff, and public safety. This was done using a wireless carrier and through a smartphone on each shuttle. The problem was the speed and the recurring data cost. We wanted to be able to track our shuttle fleet without the cellular cost and in real time. Other GPS systems that we looked at had cellular data fees and would only update once a minute. The cost of these systems were also not in the public safety budget. He knew there had to be some other options.  Being the campus radio guy, he thought that I might have seen something that would do what he wanted.  After some looking and talking with other GPS tracking  vendors, I came to the website of Raveon and the RV-M7-GX GPS modem. I knew that I had something that would do what I wanted but I wanted to to find out more.

What is the difference between M2M and IoT?

What is the difference between M2M and IoT? In this introductory article we will take a high level look, and introduce the novice to some fundamental concepts.

First off, both M2M and IoT are acronyms. M2M stands Machine to Machine (communications) while IoT is the Internet of Things. The acronym M2M has been around for a while, and in fact Raveon Technologies has been involved in M2M solutions for a decade. At the same time IoT is generally speaking a much newer acronym. Some people may consider M2M and IoT as the same thing, while others will have a very different viewpoint. In our own view IoT includes M2M solutions, but more as well.
