Satellite Network Topology
VNO
A virtual network operator does not have its own network infrastructure, but instead builds individual network solutions for companies from the infrastructures and technologies of various telecommunications providers.
In this way, global locations of a company can be networked and the secure transmission of data packets between the individual locations can be guaranteed.
IP Trunking
This technique is particularly useful for businesses that rely on many phone lines and phone services (call hold, call transfer, etc.). IP Trunking is interesting because, thanks to this technology, many numbers can be managed with a single IP-based telephone system with just one access account.
MESH
A mesh WLAN is a wireless network that is intended to ensure the widest possible coverage at the same transmission rate by combining several WLAN components for the terminals located in the mesh area.
In a meshed network, each network node is connected to one or more others. The information is passed from node to node until they reach the destination. If each participant is connected to every other participant, this is called a fully meshed network.
DVB-S2
This is the successor standard of DVB – S and thus an improved form of digital satellite television. With DVB – S2 most stations can be received in better (HD) quality. Since this technology is also more cost-effective for the stations, they will probably all change in the long term.
STAR Network / TDMA
TDMA stands for “time division multiple access”, it is therefore a multiple access method that allows multiple users to use the same transmission frequency. The users transmit in so-called timeslots, so that only a part of the available transmission bandwidth is needed and thus the same transmission frequency can be used.
This technology is used in a Star Network, where data can be transferred from one HUB station to multiple receiver stations via the satellite, and then transmit their data to the hub station in allocated timeslots.
P2P / P2 multip
Point – to – point is the easiest way to use satellites. Here, communication takes place between 2 points located under the same satellite coverage. The transmission takes place via 2 frequency channels. One channel for the outgoing signal, the other for the incoming signal.
Point – to – multipoint is a special form of multipoint link. In this form, there is a main point connected to a variety of peripheral remote stations. Any data transfer going from the Main Point will be received by all peripheral remote stations. Whereas the data transmission of each remote station is only received from the central main point.
SCPC
SCPC stands for “single channel per carrier”, in this form of satellite transmission a single channel per carrier frequency is transmitted from the transponder. SCPC is used for narrowband transmissions, this prevents interference between the signals. With SCPC you can connect to the satellite from any location, but the symbol rates are very low.
MCPC
MCPC stands for “multiple channels per carrier”. When a transmitter transmits a single carrier signal occupying the channel width of a transponder (SCPC), such a channel may be multiplexed with different multiplexing techniques, e.g. TDMA, are divided into several channels, whereby multiple channels per carrier can be transmitted.
