(MCS8 to MCS15) legacy 802.11a data rates and single stream
802.11n rates (MCS0 to MCS7) will only transmit/receive using one
chain at a time.
Please note however that these single stream rates will still take
advantage of the devices multiple antennas by using switched
diversity (the device selects one of the antennas to transmit and
receive on depending on signal strength). Switched diversity is
particularly useful for scenarios when the NVW units will be moving
at an angle that would severely alter the polarity of a single antenna
(multiple antennas can be angled differently to cover the change
between horizontal and vertical polarity). See the antenna alignment
section for further information on polarity.
Antenna Ports
The NVW-150 product features two antenna ports both connected to
one high power 5Ghz backhaul radio (these ports are labeled left and
right in the software). The NVW-250 features four antenna ports, the
inner two ports are connected to the high power backhaul radio and
the outer two to the dual band secondary radio (these ports are
labeled left and right in the software).
Power Input
The NVW-250 can be powered from industry standard v-lock
batteries or powered over Ethernet* (Passive PoE 24V-48V, 802.3af
PoE 48V-56V).
The NVW-150 can be powered from any DC 5- 20V DC Source (2 pin
Lemo Pin 1 V-, Pin 2 V+, Pin 1 is closest to the red spot) or powered
over Ethernet* (Passive PoE 9-24V).
