Tons
of paper have been used to describe how the company
may benefit from the use of information and telecommunication
systems. Nor are we to repeat the arguments about
“market superiority”, “increased effectiveness”
and “ability to remain highly responsive to the
rapid market changes”.
The specialists from the field of economy and management
should specify activities of the company that should
be supported by the tele-information systems. Our
technicians may help finding an answer for the question
whether in this particular case it is advised to
make the use of satellite data transmission network.
The type of activities of the company is not at
all important. It is crucial that the transmission
network makes the company function more efficiently.
Our services however are not to be offered to everyone…
Our customers include companies with branches, partners
or customers situated in different places in Poland.
Please note that the meaning of the word “branch”
may be far from the stereotype. Example? We connect
the teller machines of Euronet/Bankomat 24 network
and teller machine is a very specific bank branch
working on self-service basis thanks to the communication
system.
We are able to supply our services between any chosen
points in Poland: in cities (where there is often
a lack of cable network) as well as in the rural
areas (where the cable network is not expected any
time soon). Moreover, installing the equipment necessary
for supplying our services does not consume much
time, even if it is necessary to link several hundreds
of distant units. One of the SkyWAN network values
is reliability and availability. We strive to keep
our transmission services available minimum 99,5%
of the time. Because of it, they perfectly meet
the demands applied to so called transaction systems.
The term “transaction system” covers not only the
accounting services, but it also includes a very
wide range of information systems. It’s main characteristic
is an immediate registering of the transactions
made by the users, by the central database.
The SkyWAN services have been subjected to a rigorous
testing in dealing with most geographically extended
information systems, using the distributed client-server
architecture. Also, SkyWAN may support the e-mail
and workgroup systems, as well as update distribution
for price-lists, catalogues and even software systems.
SkyWAN can also be employed to collect information
from numerous sources (eg. daily register reports)
or to monitor and/or control the work of distant
devices or even systems.
In order to simplify the matter, we have defined
the packets addressed to the users of most numerous
applications (CARGO, TRANSFER, BACKUP, POS, ATM).
For those who send a lot of information we have
prepared a satellite high bandwidth solution, a
transmission via the satellite with the speeds up
to 750 kb/s or 1.5 Mb/s. It is not a fantasy, and
the cost does not have to be as high as the popular
opinion would suggest.
In summary: we offer high quality services and very
rapidly install and configure all the necessary
hardware. In many cases using our services is less
expensive than using the traditional, ground based
network operators. So… it is worth to find out more!
Perhaps finding a solution for the problems of your
company is just within your reach…
HOW DOES SKYWAN WORK?
SkyWAN is a satellite data transmission network
operated by the company DataTrans. In order to realize
connection according to the needs of our clients
different satellite technologies are used.
Several different packets have been created in order
to optimize the network capabilities to various
needs of the customers. Data transmission services
are realized through geo synchronously positioned
TELSTAR satellite.
The total territory of Poland and most European
countries are in the area ensuring good parameters
for the transmission. Offset antennas used by DataTrans
significantly reduce problems caused by the changes
in antenna reflector’s geometry due to wet snowfall
and/or icing. In addition, we offer de-icing systems.
SkyWAN is a network configured in either star or
a full mesh topology. The network communications
Hub has been situated in the suburbs of Warsaw.
The backhaul (hub connection with the company’s
central system) may be also realized via satellite.
SkyWAN.Transfer services enable creating broad geographical
systems of client-server architecture.
VSAT terminals ensuring the transmission of up to
38 400 bytes/second are used for the services offered
in the SkyWAN.Transfer packet. Access to the shares
channel is done by the „two-dimensional, slot Aloha”
protocol. In this protocol the dynamic scheduling
of VSATs covers both: time slots and the frequency
ranges. This ensures a more effective use of the
shared frequency bands.
