R4-11-4G System Planning Process 2-11
Availability covers a variety of expectations such as the percentage of time
that the network is available for service maintainability, remote monitoring,
and management. Typical questions include:
• What level of network availability is required?
• For public safety and utility customers, what percentage of time must the
network be available?
• For commercial customers, what percentage of the regular work day
must the network be available?
• What level of remote monitoring or network management is required?
• What level of support does the customer expect to do internally?
• What level of support does the customer expect from the external
provider?
On the maintainability side of the issue are the following questions:
• How much space is available for FNE installation?
• Are equipment installation sites accessible?
• What are the environmental factors of the installation spaces?
• What services are available to the installation spaces?
• What acceptance tests does the customer require for customer acceptance
and benchmarking network performance?
• How much downtime can the customer tolerate?
• What level of interchangeability or network availability does the system
require?
2.4.3 Constraints
Constraints are conditions and situations that the system designer must take
into consideration during the design stage. Some constraints are as follows:
• Not enough base sites
• Too few RF channels
• Area not covered because of poor base site locations
• Insufficient budget/phased rollout
