NOTES:
1. For non 900-MHz APs, the AP accepts a Max Range value of up to
30 miles (48 km). See Max Range on Page 249.
2. To avoid a decrease of unnecessary proportion, set to not much further
than the distance between the AP and the furthest SM that registers in
the AP.
A comparison of SM products in link with a CAP 130 is shown in Table 25.
