The link quality portion of the architecture actively maintains the quality of the mobile portion of the link. Figure 12 shows a high level control system view of the link. The scope of link quality in this section is limited to a static wireless network, i.e. no handoffs, although the feedback used in this system may indicate that QoS has degraded beyond the ability of the adaptive system to handle and a handoff is necessary. Section 10 covers this in more detail.
