alladin Nettest vs F3A Zone Pro Usage & Stats
The alladin Nettest (https://alladin.at) is an independent, crowd-sourced, open-source and open-data based solution.
• Generates and processes all results objectively, securely and transparently
• Tests 150+ parameters: speed, QoS & QoE
• Enables drive tests. Optional hardware-integration
• 100% compliant to BEREC (EU), ETSI/ITU-T standards and to TK-TVO (DE).
Our solution is more than the solution of choice among our customers: universities and international research projects increasingly use our published code as a basis and benchmark for research in the field of data transmission quality. Transparency and expertise are the template on which we base our work and development.
Further qualities of the alladin Nettest are:
Accurate
Our measurement algorithm was developed by our network experts together with government technology specialists from mobile and fixed network communications. The measurement hypotheses were iteratively falsified and/or finally verified in the laboratory under simulated network conditions. This generally formulated method of measurement is equally reliable in testing variable, slow wireless connections and stable broadband connections. It maps the typical usage behaviour of an end user in terms of monitoring period, packet size, number of threads etc.
Comprehensive
Our Nettest evaluates all the currently available Internet usage scenarios as a whole in one piece of software. This includes the usual measurements such as signal, bandwidth, latency or packet loss, but focuses particularly on parameters regarding network neutrality and quality of service. It measures how the end user experiences the quality of his personal Internet usage. A good signal is no guarantee of high speed. High speed is no guarantee of constant video transmission - and consequently no guarantee of user satisfaction either. QoE can only be described quantitatively by means of extensive QoS measurements.
Mapped
By default we use Google Maps with reduced colour spectrum as a basic map. Semi-transparent layers (Google Layers) are placed on top of them to show the points and the heat map. The heat map depicts available services such as e.g. download speed by means of two dimensions: colour and transparency. The colour defines the range of values. The transparency aggregates the number of measurements at a particular map point. The significance of the monitored service is presented and evaluated by this means. By selecting the zoom level and filter, a new heat map is generated using the PostGIS/PostgreSQL database. Our caching system guarantees prompt delivery of the map tiles.
Open
In our opinion, the most important aspect of a measurement tool is the credibility of the results. This is why we opted for open source as the most direct and most transparent type of documentation. This is the only way the functioning of the method of measurement can be verified comprehensibly and objectively. We also publish all the measurement results as open data - respecting protection of privacy, of course.
Reliable
The reliability of (aggregated) statistical evaluations depends primarily on the quality of each individual measurement result. Our quality control is fully automated and is achieved by comparison of parts of a measurement and cross-comparison with different measurements. The testing system is designed to be adaptive, i.e. once identified; irregularities are automatically identified if they occur subsequently. Measurements identified as anomalies are not censored, of course.
Significant
Uploading and downloading are measured, as are all the relevant parameters for monitoring network quality, such as latency, packet variance, jitter, packet loss etc. Furthermore, our Nettest processes all the important meta-information which describes the context of a measurement. Only by this means can measurement results be tested and validated thoroughly for significance and reliability.

F3A Zone Pro - A great way of simplifying marking out a F3A manoeuvring zone. F3A Zone Pro adds the ability to email the box to one or more friends (who also have F3A Zone Pro) - and each person can then walk toward a pole position! This makes setting up the box even quicker - no longer does one person need to walk to all three positions to identify them - now three people can head to a position each, looking at exactly the same box!
When you are practicing aerobatics (or setting up a competition site) there is no really good way of setting up some box markers to identify the F3A ‘box’. Most often you will see someone kneeling on the ground with a sighting board moving about on top of a transmitter case, with some guys guessing where 150m may be (and its usually a big guess), and trying to position the box marker poles. There is lots of arm waving and phone calling to sort out where they should be placed.
Being a keen F3A pilot, I have come up with something of a solution to these problems – F3A Zone. It is an app for iPhone and is available for FREE on the apple app store (just search for ‘F3A Zone’).
First the limitations: The app uses GPS, which has ‘variable’ accuracy. This app is a superb way of getting all 3 box markers at 150m (plus/minus a few meters) – in fact, it is the only practical way of doing this. As far as the 60 degree box angle goes, I have found the GPS positions to be at least as accurate and reproducible as a sighting board. I would be interested to hear how you get on! Remember, you can always use a sighting board to confirm the angles, knowing at least all 3 poles are at 150m.
You only need to follow a few simple steps:
1. Select how far out you want the poles positioned – typically 150m out from the pilot – other distance options are there if you have a river, etc in your way!
2. On the next screen, wait for the GPS indicator to turn green.
3. Stand where the pilot will stand and hit ‘pilot position’
4. Walk directly toward center – at least 10m – and for best accuracy a bit further like 50m or more and hit ‘on the way to center’. The further you walk here the better – this is important.
5. Now select ‘draw box’. The box marker positions are drawn on the map, along with lines joining these to the pilot position.
6. Now walk toward where the first box marker needs to go. You can zoom in on the map as you get close to the box pole positions, and locate them really accurately. Zoom back out as you head to the next marker position.
Notes:
When you start the app, wait until your GPS fix becomes accurate (green indicator) before selecting the pilot position.
The positioning relies on GPS – this app is about the only practical way to position all 3 poles at 150m. In our experience, we would say the 60 degree box angles are more reproducible with this app than a sighting board wobbling on a transmitter case. But check these angles till you have confidence in the app at your location.
You can of course ‘save the box’ – saved boxes can be retrieved at a later date to set up exactly the same site again.
The app additionally reports both distance from pilot position (just for fun), and also distance out perpendicular to the no fly line. This provides an easy method of seeing how far out someone is flying. Define the pilot position and ‘on the way to center’ as normal, then walk to say one corner of the box (somewhere safe) in line with where a pilot is flying – the ‘distance out’ is reported. Airfield elevation is also shown.
Remember, the app uses GPS – so it is not accurate enough to use to mark a ‘close in box’ at the far edge of the strip for practicing. It is good for marking out a box at 150m.
