COMIT Network Planning and Design function supports service providers with high level design (HLD) and low level design (LLD) documentation. The design can be for network roll-outs including network topology, Location Identify, Frequency, Mobility strategy, Name convention, load.... This function works closely with internal and external stakeholders to come up with the best fit and right sized network design for implementation.
HLD - High Level Design based on the business requirements and constraints. Shows the topology that will be used from a high level, what protocols will be involved and important aspects of the design from a high level. The devices that will be used in the Low Level Design (LLD) are also selected. The HLD does not contain any details such as what interfaces to use, IP addressers or any configuration. It often has an executive summary to describe to management the key concepts of the design.
High-level design (HLD) explains the architecture that would be used for developing a software product. The architecture diagram provides an overview of an entire system, identifying the main components that would be developed for the product and their interfaces. The HLD uses possibly nontechnical to mildly technical terms that should be understandable to the administrators of the system
LLD - This is a detailed document which is used to implement the design. It should contain all the details needed to implement the design such as cell level design: cellname, Lac, frequency, psc, pci, parameters,...
