1.4 Frequency Bands and Sub-bands
Much of the circuitry in the base station is common to both frequency
bands, and is therefore covered by a single description in this manual.
Where the circuitry differs between VHF and UHF, separate descriptions
are provided for each frequency band. In some cases the descriptions refer
to specific VHF or UHF bands or sub-bands, and these are identified with
the letters listed in the following table.
1.5 Product Options
The modular design of the base station means that it is available in many
variations. A range of features that can be enabled in software adds another
level of configurability. Here are some of the different products that result
from different module combinations.
Base Station/Repeater
The standard combination of modules is suitable for use as a line-connected
base station and as a repeater. This is the typical base station configuration
described in “Theory of Operation” on page 21. Depending on its PMU, it
can operate on AC power, DC power, or a combination of both.
Frequency
Identification
Frequency Band and Sub-band
VHF
B band B1 = 136MHz to 174MHz
B2 = 136MHz to 156MHz
B3 = 148MHz to 174MHz
UHF
H band H0 = 380MHz to 520MHz
a
H1 = 400MHz to 440MHz
H2 = 440MHz to 480MHz
H3 = 470MHz to 520MHz
H4 = 380MHz to 420MHz
a. Only PAs with hardware version 00.02 and later can operate from 380MHz to
520MHz. PAs with hardware version 00.01 and earlier can only operate from
400MHz to 520MHz.
K band K4 = 762MHz to 870MHz
b
b. The actual frequency coverage in this band is:
Transmit: 762MHz to 776MHz, and 850MHz to 870MHz
Receive: 792MHz to 824MHz
L band L1 = 852MHz to 854MHz and 928MHz to 930MHz
c
c. Only 5W L-band base stations are available. They currently only have compliance for
sale in Australia, and are unavailable in other markets.
