Design & test RF links

Derek Eccles

I work in the Water Industry were we use radio links for telemetry/SCADA purposes. In order to find a viable link, a desktop study is completed using “path profile” applications which is backed up by an actual on site radio test. Any help in the form of webinars, paperwork or courses would be most welcome.

    you do not mention frequency. in the range 1-2GHz you could do worse than read the COST  (COopération européenne dans le domaine de la recherche Scientifique et Technique) 231 reports that describe models you can apply (Okumura-Hata, Walfisch-Ikegami, etc.)

    If not then you are looking at more conventional and inaccurate link budget.

    An intro to a few common approaches.

    Or go to a specialist company to plan it for you.

    megalithia will give you a terrain profile.
