| Per each wireless access technology | Advantages | Disadvantages |
|---|---|---|
| Integrated method (proper for integrated standard orientation) | Efficient resource utilization (economic effectiveness-time, physical resources, maintenance management) → Basic actions (SYNC, RX/TX) that must be performed in wireless access are characterized by similar order/procedure and are therefore applicable to other access environments | Difficulty reflecting individual wireless access characteristics. It can be overcome by subdividing and implementing it so that flexibility is secured, but it is difficult to establish a standard for subdividing (quantitative rules must be established before design/implementation). Requires backward/forward compatibility support by access technology |
| Separated method (traditional way) | Possible to optimize software design/implementation for individual wireless access characteristics. → High degree of freedom in development without considering compatibility | Waste of time, physical resources, unnecessary redundant use of resources, and difficulty in maintenance management. → Required redundant implementation of similar functions. All codes of same funtions need to be corrected in case of an error. |
