cell’s sector face, the antenna field of which the user is in at that point

in the scan. The Retriever Pilot Scanner can be configured either to

lock onto that single sector regardless of its strength or to switch to

the best sector by performing idle handoffs.

List mode

In List search mode, the scanner performs one of the following scan

operations, depending upon what has been pre-loaded into the

Retriever Pilot Scanner:

_ Over-the-Air (OTA) Neighbor List only

A, N1, N2, N3... N15, N16, A, N17, N18, N19...

_ User-defined Pilot Scan List only

A, L1, L2, L3... L15, L16, A, L17, L18, L19...

SCAN_CONFIG

Parameters

For example, if the current serving system Active pilot is PN=356

and the OTA Neighbor List of the current serving sector being

demodulated is (N1=16, N2=400, N3=164, N4=8), the search pattern

will be:

356, 8, 16, 164, 400, 8, 16, 164, 400, 8, 16, 164, 400, 8,

16, 164, 400, 356, 8, 16, 164, 400...

Note The Neighbor list is searched in ascending PN order, with the Retriever Pilot

Scanner returning to the Active pilot once every 16 searches. However, this

pattern may change as the scanner occasionally tries to verify candidates for

idle handoff.

If the user has loaded a pilot list into the Pilot Scanner using the

scan_nlist command, the Pilot Scanner searches this list in ascending

PN order instead of (or in addition to) the OTA Neighbor List. For

details on scan_nlist

INCR

The incr parameter controls how the Pilot Scanner steps through PN

space in All-PNs mode. For example, with the setting incr=4,

Retriever searches PN=0,4,8,12,16... in blocks of win_siz chips.

By default, Retriever uses the Over-the-Air pilot_inc value contained

in the IS-95A or J-STD-008 Extended Neighbor List Message. This

value is recommended because the network plan uses it to
