If you are new to the two-way radio world, you may be confused with these terms. You have come to the right place to learn two-way radio technology the easiest way.



This informational site provides a short and concise explanation about two way radio technology in a neutral and un-bias way



Why We Set-Up This Site


With many radio technology and solutions being offered in the market today, choosing the right technology that can meet user requirements can be a challenging task. The first step is to understand the radio technology itself. Understand what options are available, what it can do and what it can not do, etc. Unfortunately, finding the facts and un-bias information can also be challenging with many information flying around which can be bias toward one solution.


This informational site provides a short and concise explanation about two way radio technology in a neutral and un-bias way, providing the reader with the latest and up-to-date information about this technology. This is a one stop web site that provides complete overview of current two way radio technology.



Target audience:

  • Middle and upper managers who are responsible for managing radio communications at their organizations but have little or no technical background on the radio technology

  • Any person who wanted to learn and understand about two-way radio technology and keep abreast on the latest development of the technology

  • Team member (technical or commercial team) who involves in any radio communication projects. There are sections that talk the technology in more details


More to come


Information in this site will be updated and enhanced regularly. Please keep visiting this site for latest update. Enhancements are being planned to provide comprehensive information on how to Successfully Planning and Managing Radio Communication Projects and Designing a Radio Network which will be useful for anyone involve in a radio project.
