DVB-S is currently one of the most popular methods of satellite access to the Internet. As every connection, DVB-S has its drawbacks and advantages resulting directly from its physical construction and laws that manage it. Major advantages include:

- Global reach - the technology in-question, given application of proper layout of the satellites on the orbits (rose or polar) provides practically global reach, including areas on greater latitudes (poles). Unfortunately, geostationary orbits, which provide access in areas on moderate latitudes (Europe etc.) are currently used in commercial solutions.

- flexibility - it is obvious that the technique consists in wireless radio transmission, in consequence of which, the client is independent of all types of cables connecting him to the operator. As a result, it allows for application of portable (operating without movement but with the possibility to move them) and mobile (with operation in movement option) access terminals, which conditions the flexibility through adjustment of the system for clients` needs.

There are a few problems connected with this kind of access. First of all, the operator must guarantee constant access to his network (constant access to services and incessant rendering of the given service). He is also obliged to provide proper quality of the services (QoS) and constant control of this parameter. Failure to fulfill these conditions may force today`s client with high expectations (ex. a bank) to use services offered by a different operator. The next problem is the maximal radiation power of the receiving-dispatching system (EIRP), which is strictly determined by Telecommunication Regulatory Offices in the given country. The remaining, rather important aspects include: right capacity of the system and provision the necessary bandwidths in proper frequency ranges.

A crucial feature of the teleinformatic system are minor delays in transmission. As it was mentioned before, construction of the link itself (precisely distance between the satellite and Earth) introduces certain limitations connected with the speed of propagation of the electromagnetic wave in free space. The picture below presents the possible orbits on which satellites can be located. Logically, the shortest transmission delays will take place in case of units placed closer to Earth. Theoretic transmission delays for individual orbits are:

- LEO (Low Earth Orbit) - from 2 to 50ms
- MEO (Medium Earth Orbit) - from 30 to 70ms
- GSO (GeoStationary Orbit) - approx.120ms
- HEO (High Eliptical Orbit) - undetermined value due to far too great changes of the distance from Earth in time function

The satellite access systems usually operate in two frequency bands: Ku (10-18GHz) and Ka (18-31GHz). Ka band was divided into two sub-bands: dedicated to the `downward` link (satellite-terminal) - 19.7-21.2 GHz and to the `upward` link (terminal-satellite) - 29.5-31 GHz. Moreover, application of the so-called V band(40-75GHz) is also planned in communication via satellite. Multi-access to the system is realized in MF-TDMA (Multi Frequency Time Division Multiple Access) system, which consists in separation of particular tome spaces for the user in a given (one of many) frequency band (3 transmission dimensions - time, frequency and level of the signal).
