Answers about the topic How does skyDSL2+ work?

Are the data rates guaranteed?

With skyDSL - as with any wireless technology - the service allocated for an approved frequency spectrum is shared by the users. Intelligent methods and modern technology help to create an efficient and smooth use of the promised resources. Despite these techniques and careful monitoring of the systems, the maximum bandwidth cannot be guaranteed at all times. The specified data rates are given accordingly to a maximum value. Please note further that it is at these specified gross data rate values that the service will be for you as user specified. Some factors, such as the quality of the transmission path for instance, which is also determined for example by the orientation of the mounted satellite antenna as well as the applications that also transfer data protocols determine the ratio between gross and net values. In ordinary use and good alignment of the satellite antenna you can count on the usual 80% to 90% of the indicated gross data rate. The current data rates of our tariffs can be checked at our skyDSL Monitor.

How far away must the obstacles be in order to ensure reception of the signal? (free view to the south)

Within Germany the elevation angle of the antenna is approximately 28 ° in the north and 35 ° in the south. This results in about 50cm to 70cm rise (of the signal) per meter of distance. An obstacle must therefore not be higher than 2.5 m to 3.5 m when it is 5m away. At a distance of 10m from the obstacle, the object must not be higher than 5m to 7m and at a distance of 15m, not higher than 7.5 m to 10.50m. If the obstacles are higher, then either the distance to the obstacle must be increased or the satellite antenna must be respectively assembled higher, for a faultless reception of the signal.

Elevation          Slope (based on the distance of 1 m)
A                        B
28 °                   53 cm
29 °                   55 cm
30 °                   57 cm
31 °                   60 cm
32 °                   62 cm
33 °                   64 cm
34 °                   67 cm
35 °                   70 cm

What does VOIP mean?

VoIP is the short form of Voice over IP. It is also called internet phone or IP phone and designates the calls using the internet. One prerequisite for the use of VoIP is a skyDSL2 + broadband connection. The VoIP connection of skyDSL uses the SIP protocol (Session Initiation Protocol), which is the most frequently used protocol for VoIP.
to top

What device do I need in order to make calls using VoIP?

Three different connection scenarios are suitable for this purpose! If you want to further use your current phone, you need a VoIP enabled router (e.g. a AVM Fritzbox). This hardware is connected simply and directly to the skyDSL2 + modem. Your computer and your phone are then connected directly to the VoIP enabled router. Alternatively you can also use a VoIP enabled phone. Please note that the skyDSL2+ modem provides only one Ethernet port. Since your computer requires this connection, a router is also needed in this case. This must, however, not be VoIP enabled. Of course VoIP also works with a VoIP software on your PC. Please note that in this case your VoIP connection is only ready to be operated, if your PC is switched on and the VoIP software is ready for use. Current VoIP software can be found here:

Does my PC have to be on in order to telephone?

If you use a VoIP-enabled telephone or your analogue telephone is connected to a VoIP-enabled router with an analogue connection, you can make calls independently of your PC. If you are using software on your PC to make calls, this must be switched on and the software must be ready for operation.
