TECHNICAL SYSTEM REQUIREMENTS
List of Differences
R4-11-4G System Planning Process 2-13
A customer’s current operations, moving to a future scenario are based on
the customer’s perception. If the customer is not serving their customers in
the most efficient manner, or serving a market or class of customers that
provide growth and profitability, then using a Private DataTAC network to
address the customer’s need to change is weighed against the various
possible solutions.
2.5.3 List of Differences
While comparing the two operational scenarios, create a list of the
differences. Organize the list into what customers do that is different and
what equipment, networks, or systems are required to help them to do it.
Total customer satisfaction depends on the customer’s confirmation of this
list of processes and procedures.
2.6 Technical System Requirements
The system engineer, using the results of the application analysis and system
analysis, specifies the customer’s technical system requirements. This phase
leads into the system design process.
There are three technical requirements: functional, architectural and
performance. They are described in the following subsections.
2.6.1 Functional Requirements
Functional requirements describe the specific data transfer and processing
required for information flow through the system. The requirements
typically relate to the host and wireless computer applications or system
routing requirements.
The system engineer must analyze the following system functional
requirements for every Private DataTAC network design:
• Host application functions
• Wireless computer functions
• Network management functions
• Host and mobile computer connectivity
• Wireless computer mobility
2.6.2 Architectural Requirements
Architectural requirements describe the physical location, the connections
between equipment, and the logical distribution of processing. The main
areas of concern are radio site location, communications links, and radio
frequency planning.
