determine what legal PN offsets are assigned to each sector face of

each cell. However, any value (1,2,3...) can be entered by the user as

well.

WIN_SIZ

The win_siz parameter controls how many chips delay (or advance)

from the Active pilot the searcher scans for each PN. The choices are

Use WinN (1), Incr*64 (0), and User specified (2... 512).

Incr*64 mode (recommended)

By default, the Retriever Pilot Scanner uses Incr*64 (0). In this mode,

the entire 32,768-chip PN space is broken up into equal windows of

Incr*64 chips centered on each PN offset on increment incr.

Therefore, if incr=4, the PN space will be divided evenly into 128 PN

offset windows, each 256 chips wide. This setting covers the entire

32,768 chips of the short-code with no overlap or gaps in time.

On an average, the RF propagation yields approximately 6.5 chips

per mile of propagation delay. This means that if incr=4 and

win_siz=256, cells approximately 19.5 miles away can be uniquely

resolved by the Pilot Scanner.

Use WinN and User Specified modes

The Use WinN and User Specified modes are not recommended

unless the user is certain of the purpose and goals of controlling this

variable.

In Use WinN (1) mode, the Retriever Pilot Scanner uses the OTA Air

Neighbor window of the Active serving sector for its search

window. This mode can be used when it is known that Neighbor

windows are well-tailored in a particular area.

In User Specified mode, any window size from 2 to 512 can be

entered by the user.

Note Using either the Use WinN mode or the User Specified mode can result in

problems. If the windows chosen are too small, important RF information may

be missed. If the windows chosen are too large, PN ambiguities may be

introduced.

INTEG

The integ parameter controls how long the Retriever Pilot Scanner’s
