The radios on outdoor units (bridges) have higher transmit power levels than radios on indoor units (access

level for the receiver. At levels above the normal operating range, packet error rate (PER) performance is
degraded. At even higher levels, the receiver can be permanently damaged. To avoid receiver damage and
PER degradation, you can use one of the following techniques:
