13.10.1 Type 1 Interference
Downlink to Subscriber Unit
interfered with by another Access
Point Downlink. All Access Points
power control for full service at the
sector edge (in cusp). The worst
case scenario is when the SU (Cell
1) has the interfering AP at
Boresight (Cell 2) and is towards the
edge of its sector, i.e. min CNR from
its AP.

13.10.2 Type 2 Interference
Downlink to Subscriber Unit
interfered with by a Subscriber Unit
Uplink in another cell. Worst case
scenario is interfering SU at range
(max Tx power), and victim SU at
range (lowest CNR) and SUs facing
each other, e.g. Cells 1 and 3. The
interference is reduced if SUs using
the same frequencies do not face
each other, e.g., Cells 1 and 2.
