General Design and Engineering Process
The general design process of a
Sky
WAN
®
network is an ongoing process starting with com-
piling the end user requirements. Result is a cost efficient network, fulfilling the service require-
ments defined. The process may be summarized by the following picture:

Overview Design and Engineering Process
Good requirement engineering is the basis of a well designed network and should not be ne-
glected. With the customer input information you start to engineer the network including the as-
pects cost, feasibility and product characteristics. If the solution is satisfying, the network will
be implemented. To prove the successfull realization of the requirements some tests have to
be done. If a service does not meet the customer conditions, a new design phase is required.
Customer Input which is required as a starting point for the design typically consists of the fol-
lowing information:
-
Description of applications and utilisation scenarios.
-
Descripton of the customer network environment.
-
Satellite transponder data.
-
Station locations.
-

requirements.
-
Specific requirements for IP based applications.
-
Specific requirements for Frame Relay applications and the Frame Relay Access Device.
To request these parameters from a customer, a standardized questionnaire form ’
Sky
WAN
®
Network Design and Engineering Requirements’ may be used.
The core
Sky
WAN
®
design process can be split into different phases, which are linked:
-
The general carrier design, where all carrier specific data is defined.
-
The outdoor units design, where all outdoor specific data, including the space segment is
defined.
-
The detailed indoor unit design, where all details about hardware and licenses are defined.
-
The finalization of the design including costs optimization.
These steps are discussed in detail within the subsequent sections of this guide.
