What is meant by SAT

Sat TV via WLAN: wireless satellite TV

Satellite television still connects many with huge fuss, long cables, and riddled walls. And that with every new television that is to be connected to the system.

In the meantime, times have become rosier: You can now also broadcast satellite TV via WLAN. On televisions, smartphones, tablets and everything in between.

Sat> IP makes it possible

If you've never heard of SAT> IP, it's best to read our SAT-IP Guide. There the relatively new standard is explained in detail.

The short version: a SAT> IP server converts the satellite signal into an IP signal and feeds this into your home network. Any number of participants can then access the satellite signal (how many at the same time being able to watch TV, however, depends on the server).

What you need to feed your satellite signal into the WLAN

You will probably already have most of the equipment. For this article we assume that you are already operating a satellite system.

In any case, here is a list of components that you either need to upgrade or upgrade.

Sat> IP server

Without it, nothing works - because only then does the satellite signal from the coaxial cable become a signal that can be routed via Ethernet or WLAN.

Depending on the manufacturer, the device is called server or converter. There are also variants of the designation Sat> IP, such as Sat over IP,Sat2IP etc. What is meant in all cases is the same.

To be considered when purchasing

What you want to look out for the most is the server supply enough participants at the same time can.

Maybe you might only two televisions have in the house. With the satellite signal in the WLAN you can do this can also be accessed e.g. via smartphone If you now live with six people in a single-family house, you can quickly reach more than four simultaneous participants - including the kids with smartphones.

But even if you buy a server that can reach eight participants at the same time: if a single LNB is attached to the satellite dish, only one participant can be supplied in the WLAN. You can find more information on this in the SAT> IP Guide. If your current set-up is sufficient for you in terms of maximum participants, it will not be any different with Sat> IP 😉

WLAN router - enough bandwidth?

Most people will probably have to upgrade here.

Many home networks are simply managed by the router provided by the Internet provider. For a simple home network, that may be quite sufficient.

If, on the other hand, you plan to supply the whole family with satellite TV via the same network - and at the same time - the box starts to gasp.

Kathrein recommends around one per channel Data throughput of 20 Mbit / s. This can be done quickly via LAN, but it looks different with WLAN.

Current WLAN standards

The biggest hurdle - especially for cheap routers - is an outdated wireless standard.

The currently widely used standard 802.11n theoretically creates bit rates of up to 600 Mbit / s. This is only available if the router is MIMO-capable and uses SMX. For this, the transmitter and receiver would have to have installed a corresponding number of WiFi antennas.

802.11ac Routers have wider data channels and therefore a higher data throughput from the outset: at least 433 Mbit / s for one data channel.

Problem: Sender and receiver have to be up-to-date

But even if you get the fastest router, your receiving devices could become the brakes.

With an 802.11ac router you have at least the advantage that devices that only support 802.11n are compatible with it (in the 5GHz radio range). With 802.11n or older, everyone is equally slow.

TV with integrated satellite> IP reception

If you ultimately want to output the signal to a television, it should be able to receive it.

At the moment there are not many TVs on the market that are complete SAT> IP subscribers. Panasonic are in the lead with devices like the Viera. These are then used in a similar way to television with a DVB-C connection - practically plug & play.

One or the other may be able to get the signal to be received with firmware / software updates. To this extent, however, even from larger manufacturers such as Samsung or LG, no satellite IP apps that can be obtained from the respective app stores are available. What is really frustrating - all a smart TV would be missing would be the software that communicates with the server.

It is possible that this will be submitted in a while.

Until then: SAT> IP Receiver

A receiver throws the concept of Sat> IP overboard. But if you don't want to look around for a new TV right now, this is the easiest way to bring the signal to your existing TV.

Such receivers do not differ significantly from conventional ones. Often the Sat> IP function is just an additional function of a normal receiver. Well-known devices would be the Inverto Volksbox or Kathrein USF 924sw

If your TV can SAT> IP, but does not receive WiFi

In the event that you have a SAT> IP capable television but which does not receive WiFi:

A WLAN bridge intercepts a WLAN signal and outputs it again via LAN cable. In this way, wired devices can also be integrated into a wireless network.

In any case, check beforehand whether your television set has a LAN socket.
