 === Client ===
+While the transmission protocol of the FLARM devices are proprietary (and unusable for our purpose), the [http://www.flarm.com/support/manual/FLARM_DataportManual_v6.00E.pdf Data Port Specification] is public. The client software uses the data available on the devices Data Port, just like any 3rd party product.
+
+The concept of the client software is quite simple. It reads the Data Port from a regular FLARM device (RS232 interface) and streams the data (via the HTTP protocol) to the server which does all computing. Since data streaming does not require much computing power, a mini-computer like the Raspberry PI is sufficient. 
 
 ==== Hardware ====
-We use a [http://www.raspberrypi.org Raspberry PI] in our pilot installation. This is a low-cost device (around 50$) that is able to run a Debian-based operating system (Raspbian).

+===== Infrastructure & Assembly =====
+We used the following components to build up our client infrastructure. Note that links provided are just proposals for your convenience, other components will also work.

+  - a power adapter and data cable for the FLARM device, we use currently this [http://shop.segelflugbedarf24.de/product_info.php?info=p32_Update-Cable-RS232.html update cable]
+  - a [http://www.raspberrypi.org Raspberry PI]
+  - a USB charger to power the Raspberry, just make sure it can deliver at least 1000mA
+  - optional, recommended for a stationary installation: we use currently an [http://shop.segelflugbedarf24.de/product_info.php?info=p29_FLARM--Outside-Antenna-4-m-cable.html external antenna]
