Beginners

Where do I start?

1. Create a free user account
2. Order some credits or test with a free 7 day trial plan
3. Login to the web interface to start planning
4. Read the user guide for the web interface

We've written a generic beginner's guide to RF planning which will give you enough knowledge to navigate the various interfaces with confidence.

System capabilities

Can you model the coverage of (wireless technology)?

If you know your system's frequency, RF power, heights then yes. You can find this information in the documentation or on the FCC ID lookup website. The more you know about the system and the environment, the more accurate a prediction you will get. What the (generic) system cannot help you with are system specific parameters (above the physical layer) such as channel capacity within LTE. If you stay focused on the physical layer and appreciate that all RF communications regardless of how innovative they may be start with an oscillating electrical signal which is fed to a terminating element from where it radiates. The modelling for this can be done irrespective of protocol using agnostic values like gain and pathloss.

Can you model LTE, TETRA, WiMAX, 802.11b/g/n/ad, Radar, Air-to-ground, Ground-to-air, Microwave, 802.15.4, Zigbee, LoRa, 868, DMR, PMR, Wi-Gig?

Yes to all. See answer above.

How can I process lots of sites from a spreadsheet?

Use the API and Python client we made for this purpose. It's been proven against over 50,000 sites at once.

How can I download my data?

Login to your private archive and use the download buttons on the right. You can choose what GIS format you would like your data in or receive HTML embed code to put it on your own website.

What gain value do the antenna patterns use?

The 3D antenna patterns use relative field strength between zero and one, relative to the main lobe (1.00). Therefore a relative field strength of 0.5 will have 50% maximum power.
You can set whatever antenna gain you like for the main lobe using the gain field in dBi (relative to isotropic antenna) eg. 24dBi. If you have additional losses or gains in your link budget you want to factor in you can do that with through the Tx or Rx gain values - or receiver sensitivity.

What clutter data do you use?

The system has three clutter types to enhance accuracy: Random clutter, used to represent unpredictable or complex clutter at a similar height eg. 6m.
User defined clutter, used to depict precise obstacles through the import of Google earth KML overlays which may not exist eg. a future windfarm.
LIDAR raster data. Used for mapping buildings in urban areas where LIDAR data is available.

What happened to the Android app RFSignal?

Back in 2011, we launched the first mobile radio planning app for Android which allowed users to perform 100km area calculations, powered by a dedicated server. The app was popular and received excellent reviews but eventually was pirated. Aside from impacting sales it meant that valuable server resources were being taken away by pirates from paying customers.
To combat the piracy, an update to the app was released which required customers to enter a lengthy Google Play order number which could be checked against orders. This proved unpopular and took time away from the app's development. Regretfully we retired RFSignal. Users who purchased the app after 20th March 2014 may request a refund via the contact form or Google Play. In it's place, we'd like to encourage RFSignal users to install the free 'Keyhole Radio' app for Android which looks a lot like RFSignal only it integrates with your CloudRF account so anything you do on the app can be recovered in the other interfaces and your central archive.

Web interface

How do I set the precise location? That moving cursor drives me nuts

You can type in a GPS accurate grid reference in either decimal degrees, degrees minutes seconds or MGRS into the location input box and ignore the moving cursor.
You can also click the icon-like button in the LOCATION menu to hide the cursor and click-to-update functionality to operate from manually entered locations only.

Can I download the background mapping?

No. You can take a screenshot and use that but the licensing of the third party mapping (Mapbox OSM) does not permit bulk downloading or public display without permission. The coverage layers you create belong to you and you do not need permission to share and display those although we'd be happy for a link.

Keyhole Radio for Google earth

Where's the login box?

Sometimes the discrete login popup appears behind the active Google earth on Windows. Look on your taskbar for a second Google earth application and click it to bring the login box to the front or use Alt-Tab to find it in your active apps.

How do I set the precise location? That moving cursor drives me nuts

You can type in a GPS accurate grid reference in either decimal degrees, degrees minutes seconds or MGRS into the location input box and ignore the moving cursor.

My cursor isn't in the middle, it's offset near the edge of my view?

Straighten up your view so you are looking directly down at the earth, not at an angle.

All my saved layers have stopped working. All I get are big red crosses?

Google earth supports two major types of layers: KML and KMZ. A KML file links out to other files and a KMZ is a compressed (Zipped) KML which significantly contains all the files so it works without network access. CloudRF offers only KMZ files for download so you have everything you need - and it also lightens the load on our servers.
When you open layers in Google earth and re-save them, be sure to save as KMZ not KML. If you save as a KML, it may not work forever when links change. A recent update to Keyhole Radio has seen the address change which broke KML links. If this affects you, you should download your layers from your archive as KMZ files. A technical description of a compatibility issue with Google earth and SSL we found is here.

It doesn't connect? Link is red

Open TCP port 8443 (outbound) on your network firewall.

Legal

How can you do this with open source? Shouldn't it all be free?

The open source engine that powers this service is available for free here. Unlike others who charge a lot to use legacy closed-source freeware, we have published, invested and extended our engine to improve it with features like multi-threading, sub 1 metre accuracy and additional propagation models to name a few. A full changelog is available within the GIT repository. The service is hosted on expensive servers and maintained 24/7. This needs paying for.

Can I take your layers and pass them off as my own bespoke work for a huge markup?

You can try but your clients will find out sooner or later. Honesty is the best policy and under section 3.3 of our terms, we require some attribution. How you do this we'll leave up to you.
