1 INTRODUCTION
1.1 Summary
Sky WAN
®
is a flexible and versatile VSAT system to establish wide area corporate network in-
frastructures via satellite for enterprises and governmental institutions, supporting a wide vari-
ety of end user business applications.
The Sky WAN
®
Indoor Unit (IDU) is a satellite modem with advanced features. It offers multi-
media services (voice, video) and data transport sent with small antennas over transparent sat-
ellite transponder frequency channels. Beside the IDU, a
Sky WAN
®
network contains outdoor
equipment (ODU) like antenna, transceiver, amplifier, control units, redundancy control units,
converters etc. as engineered for customer premisses.

1.2 Manual Content
This Sky WAN
®
Network Design and Engineering Guide provides information about how to de-
sign and engineer a Sky WAN
®
Satellite Network based on the Sky WAN
®
IDU modem series.
Some typical network design scenarios will be discussed; starting from customer traffic require-
ments an optimized
Sky WAN
®
Carrier and Outdoor Unit Design will be derived using the ND
Satcom Design tools discussed.
This guide consists of the following main sections:
-
General Carrier Design .
The Sky WAN
®
Satellite Link Layer implementation and functionality is described. A de-
tailed description of the Time Division Multiple Access (TDMA) structure of Sky WAN
®
car-
riers is given. The procedure how to translate customer network traffic requirements into
an optimized
Sky WAN
®
carrier structure is outlined. The ND Satcom Design Tools for this
purpose are described.
