Unlike the antennas in other FSK Cambium radios, the integrated antenna in the 900-MHz radio is
horizontally polarized to reduce exposure to noise from vertically polarized signals, which
predominate in this band.
Connectorized for External Antenna
The enclosure of the 900-MHz connectorized AP and SM includes a cable and N-type connector
to which an external antenna can attach. In this case, network operators can select horizontal or
vertical polarization and select the type of antenna to use. However, these connectorized modules
can be used in the same architecture with the integrated modules only if the connectorized
modules are horizontally polarized.
PTP Series 100 Bridges
A pair of PTP 100 Series wireless Ethernet bridges
provides point-to-point connectivity as either a
standalone link or a link through a cluster
management module to an AP cluster.
You must configure a BH as either a timing master
(BHM) or timing slave (BHS). The BHM provides
synchronization signal (sync) to the BHS.
A BH mounted to a passive reflector dish is pictured
in Figure 6. Carrier applications for these modules
include reaching remote AP clusters,
interconnecting campus buildings or remote branch
offices, extending private branch exchange (PBX)
circuits, backhauling cell sites, and extending
central office T1s/E1s.
These BHs are supported by this user guide. See
Realizing a Wireless Ethernet Bridge Network
on Page 33.
