SkyWAN©.Cargo
Corporate satellite network
This service is addressed to the users with extensive transmission demands, seeking at the same time a minimum cost solutions. The SkyWAN.Cargo network has been created for the high bandwidth applications allowing to create LAN and WAN networks, corporate Intranet and Internet networks, VPN (Virtual Private Networks), telemedicine and Remote Learning purposes. Satellite terminals allow building of private separated networks, whose throughput can be expressed as a total and/or multiple of any of 750kbps. Throughput of 1,5Mbps may be offered as an option. Beside the standard of

IP protocol, one may choose between Frame Relay and ATM protocols.
A significant feature of this service is that no fees are charged for the generated traffic - the customer pays only fixed fees for the assigned network resources. The type of bandwidth assigned to the client’s network may be increased in steps of 750kbps according to one’s needs. This satellite bandwidth is shared among all nodes of customer’s separated network.

The principle of dynamic bandwidth allocation
The bandwidth is allocated between the stations requesting transmission in each time frame of several tens of milliseconds, which satisfies the demand for transmission of each node. In case of a temporary overflow of available bandwidth, the whole excess bandwidth is allocated to currently transmitting nodes, to minimize the transmission time. In this way the dynamic allocation of bandwidth allows it to be used in the optimum way.

There are no privileged nodes in the SkyWAN.Cargo service- transmission between any nodes takes place along the shortest route and that means minimum possible delays in transmission and a supports any configuration of links (full-mesh).

Extraordinary flexibility and scalability of the network
The band allocated to the customer’s whole network may be any multiple of a segment allowing for the transmission speeds ranging from 750 kbps to up to 30 Mbps. This network may be freely extended as far as the number of nodes or the throughput are concerned. It is especially possible to add new nodes without changing the transmission bandwidth allocated to the network or to increase the transmission bandwidth with the unchanged number of nodes. It is also possible to set an asymmetric transmission for the customer generated network traffic.

                            SkyWAN©.Transfer
The SkyWAN.Transfer service is provided on the basis of a teleport in Legionowo, operated jointly with the company Grytek which today operates near 800 VSAT stations (satellite terminals), connecting more than 5,300 end points. There are up to 20.00 electronic cash flow transactions being realized in this system each minute. All these transactions require the highest levels of the system reliability and quality of transmission and service. Its modular architecture scales easily allowing it to adjust the network capacity to the continuously growing needs of the users. This service has been created for the demanding users, interested in both: transaction handling (deposit and/or withdrawal registration, authorizing the withdrawals from teller machines or payments with credit cards) as well as narrow-band batch transmission (transferring the daily reports, pricelists, catalogues, distributing the software)

                            SkyWAN©.BACKUP
This service, using the narrow-bandwidth technology has been optimized taking into consideration the economical effectiveness for substitute links. The branches ASSIGNED by the client are connected via satellite (single satellite hop) through the narrow-band VSAT station with the DataTrans’ central station in Legionowo and then, through the narrow- band VSAT station (double satellite hop) or (optionally) through the POLPAK-T ground link with the customer’s central network node. Option with a ground link between the central station in Legionowo and the customer’s central node helps prevents the transmission delay on the satellite link. Set up this way they remain a substitute for customer’s existing or planned ground links.

VSAT station gives the possibility of direct connection to LAN network with the Internet Protocol (IP) and Ethernet 10BaseT interface or with X.25 protocol with RS-232 interface.

Configuration is completely independent of the client’s ground links. Configuration is independent of the ground link between the leaf node (client’s localization) and the SkyWAN network central station in Legionowo. However, the ground link (radioline, POLPAK-T) is used between Legionowo and client’s central unit.

Configuration similar to B with additional satellite substitute link between the central station in Legionowo and customer’s headquarters. All solutions are controlled by the remote management system, which helps to provide an early troubleshooting and remote diagnostic every port.

                            SkyWAN©.POS
This service using the narrow-bandwidth technology has been designed and configured so as to cooperate with POS (Point Of Sale) terminals and integrated cash systems in order to communicate with credit card authorization center. The branches specified by the client are connected via satellite (single satellite hop) through the narrow-band VSAT station with the DataTrans’ central station in Legionowo and then, through the narrow-band VSAT station (double satellite hop) or (optionally) through the POLPAK-T ground link with the credit cards authorization center. VSAT station gives the possibility of direct connection to LAN network with the Internet Protocol (IP) and Ethernet 10BaseT interface or with X.25 protocol with RS 232 interface.

Serial ports have been configured to enable a direct connection of the POS terminal supplied by the Credit Card Authorization Center. It is possible to directly connect via the Ethernet port the VSAT station to LAN network at the sale point. And to cooperate with the applications managing the integrated cash systems

There are 3 technical solutions available in the SkyWAN.POS option:

SkyWAN.POS-2
End point stations will be connected via satellite with the DataTrans central station in Legionowo through VSAT station supplied with 2 serial ports (RS 232) allowing to connect two POS terminals.

SkyWAN.POS-6
Leaf node stations will be connected via satellite with the DataTrans central station in Legionowo through VSAT station supplied with 6 serial ports (RS 232) allowing to connect six POS terminals.

SkyWAN.POS ETHERNET
Leaf node stations will be connected via satellite with the DataTrans central station in Legionowo through VSAT station supplied with 2 serial ports (RS 232) and Ethernet 10baseT port allowing to connect two POS terminals or any number of cash systems working with one server with no router necessary. All solutions are controlled by the remote management system, which helps to provide an early troubleshooting and remote diagnostic every port.

                            SkyWAN©.ATM
It is a narrow-band based service optimised and configured so as to cooperate with teller machines and communicate with teller machines’ authorization centres. ATMs are connected to SkyWAN end points via satellite (single satellite hop) or through a low bandwidth VSAT stations with the DataTrans central station in Legionowo and then, through POLPAK-T ground link with the authorization centre.

VSAT station gives the possibility of direct connection to LAN network with the Internet Protocol (IP) and Ethernet 10BaseT interface or with X.25 protocol with RS 232 interface.

There are two technical solutions available within the SkyWAN.ATM:

SkyWAN.ATM X.25
End point stations will be connected via satellite with the DataTrans central station in Legionowo through VSAT station supplied with serial port (RS 232) allowing to connect ATM (possibility of further connection up to 6 serial ports). Single station may be used to connect max. 6 teller machines.
