802.11 Networks on Radio Mobile (Part 2) - Coverage Maps

15:53 Posted by Jurgens Krause networking, radiomobile, wireless 1 comment

Now that we have mastered point to point links using RM, the next major feature is generating coverage maps.

For this tutorial we will be continuing with our Fictional WISP, SaharaWisp. We already have our two highsites configured, and we have a link running between the two. We are now going to be adding two 5.8ghz sectorized antennas to each tower, and plotting the resulting coverage.

Start by opening your existing network file in Radio Mobile.

Before reading this tutorial, you might want to take a look at Introduction to Radio Mobile

This tutorial will cover the creation of your first 5.8 ghz network with a single point to point link. You will learn how to create units, set network parameters, and create a point to point link profile.

Introduction to Radio Mobile

Radio Mobile is a free (not open source) RF Propagation simulator. Originally intended for amateur radio operators, the software is also perfect for plotting long distance wireless links on the 2.4ghz and 5.8ghz bands (and any other for that matter).

You can find thorough documentation for the software on http://radiomobile.pe1mew.nl/ but I would like to make a few tutorials specifically geared towards 802.11 networks.

Raspbian on Windows with Installer (VirtualBerry)

08:13 Posted by Jurgens Krause linux, raspberry pi, windows 2 comments

Getting Raspbian running on a virtual machine can be very useful if you do development, or just want to play around. Easy to use solutions like VirtualBox unfortunately cannot emulate anything other than x64 or i386 CPUs, while the Raspberry runs on an ARM chip.

Enter Qemu, an open source virtualization host that can run on Windows, Mac or Linux and emulate a wide variety of CPUs, inlcuding the ARM chip that the Raspberry Pi is based on.

I have created an installer for Qemu that is preconfigured with the latest Raspbian image (Jan 2014) at the time of writing this, but still there are a couple of steps required to get it working 100%

Radio Mobile Installer

Radiomobile is one of the best RF propagation modelling programs, and certainly the best free one available. One of the drawbacks has always been that it does not come with an installer, so, with the permission of the developer I have created a simple installer for it. It includes all the Radiomobile languages. Although it is not officially sanctioned, it was created with the input of the developer of Radiomobile.

Please note that this installer is still in development, but every effort has been made to ensure that it is without errors. If you find an error, please report it in the comments section.

You can download the installer here:
