B.2.1
700 MHz Filter Naming Convention
Westell Technologies digital repeaters use an alphanumeric file naming convention for its filter files. The descriptions
below will allow you to understand the methodology to determine the desired file for your application.

NOTE
Modulation type determines the guard band at the edges of each passband. The
modulation type field will also be used to indicate a carrier who has a unique sub-
block designation.
Up to four sub-blocks may be defined, resulting in a maximum filename length.
All variant/guard band designators other than 0 (zero) and F are user-defined custom filters.
700 MHz examples
llA1B1-0 = (700 MHz band, E-UTRA mod type, Lower A1, B1, with standard guard band). leC0-0 = (700MHz band, E-
UTRA mod type, Upper C, with standard guard band).
llC1-0 = (700 MHz band, E-UTRA mod type, Lower C1, with standard guard band).
