Operation Modes
Bridge operating mode is selected by default. In this mode the
device will act as a transparent bridge and will operate at Layer 2.
There will be no network segmentation and the broadcast domain
will be the same. Bridge mode will not block any broadcast or
multicast traffic. Additional Firewall settings can be configured for
Layer 2 packet filtering and access control. In bridge mode the device
forwards all the network management and data packets from one
network interface to the other without any intelligent routing. For
simple applications this provides an efficient and fully transparent
network solution. WLAN (wireless) and LAN (Ethernet) interfaces
belong to the same network segment which has the same IP address
space. The devices IP address is for management purposes only.
Router operating mode can be configured in order to operate at
Layer 3 to perform routing and enable network segmentation, clients
will be on a different IP subnet. Router mode will block broadcasts
and is not transparent.
The device supports Multicast packet pass-through when in Router
mode. The router can use the Network Address Translation
(Masquerading) feature, NAT will act as the firewall between the LAN
and WLAN networks. Additional Firewall settings can be configured
for Layer 3 packet filtering and access control when in Router mode.
Access Point WDS Mode
This is mode is generally used for point-to-point or point-to-multi-
point connections between NVW units. A unit in Access Point WDS
mode should be used in conjunction other units in Station WDS

8
Datavideo Technologies Co., Ltd
www.datavideo.info
mode in order to build the point to point and multi-point
connections. This is the most commonly used mode to connect two
units, by using the WDS (Wireless Distribution System) protocol both
devices are connected transparently just like having an Ethernet
cable between them.
Station WDS Mode
A device in Station WDS mode must be connected to another unit
configured in Access Point WDS mode. This is the most commonly
used mode to connect two units, by using the WDS (Wireless
Distribution System) protocol both devices are connected
transparently just like having an Ethernet cable between them.
One unit is setup as Access Point
WDS and the other as Station
WDS (Transparent Client).
One unit is setup as Access Point
WDS and several other devices
as Station WDS (Transparent
Clients).

Repeater WDS Mode
Repeater WDS Mode is used to extend the wireless range and
coverage of the wireless network between units.
In Repeater mode, the unit acts as a relay by regenerating the signals
it receives and retransmitting them to main network infrastructure.
Note: Repeater WDS requires another unit setup in Access Point
WDS mode in order to work.
Station Mode
In Station mode the device acts as a wireless client.
Use this mode to connect the NVW unit to any standard access point
or wireless router. When connected to an access point the wired

10
Datavideo Technologies Co., Ltd
www.datavideo.info
network ports are bridged to the wireless network. This mode
translates all the packets that pass through device to its own MAC
address, thus resulting in a lack of transparency.
Note: We cannot guarantee compatibility with all access
points/routers.
Access Point Mode
The Access Point Mode is the default mode of the device. In this
mode the unit simply bridges the wireless clients to other wired and
wireless network infrastructure.
Router Mode
In Router Mode, the device operates as a router.
Either the wireless or Ethernet can be setup as the WAN connection.

11
Datavideo Technologies Co., Ltd
www.datavideo.info
Wireless as WAN is known as Station + Router mode (or Wireless
Routing Client mode) or Ethernet as WAN is known as AP +
Router mode (or Gateway mode). This device supports several
types of broadband connections Static IP, Dynamic IP and PPPoE.
Quick Setup (Pairing multiple NVW Units)
By default the NVW-150 and NVW-250 units are configured ready to
pair with each other, we simply need to specify which unit will be the
access point and which unit(s) will be the station(s). Use this mode to
create a long distance link between the two or more NVW units and
then connect your devices at each end.

Hardware Configuration & Considerations
This section will show you how to install the hardware of the NVW-
150 / NVW-250 unit and its optional accessories.
Antenna Selection
It is important to remember that antennas create gain by focusing or
directing signals, this means that for an antenna to provide increased
gain it will be focusing the signal in one direction so we must loose
signal in another direction.
A 0dBi Omni-directional antenna creates a perfect spherical response
meaning that the signal is spread equally in all directions (360 degree
vertical and horizontal planes). A standard 3dBi Omni-directional
antenna creates a doughnut shaped response, we have gained signal
from the side of the antenna at the cost of losing it above the
antenna (narrower vertical plane). This effect is increased when we
move to say an 8dBi Omni-directional antenna, we now have a thin
disc shaped response (even narrower vertical beam width) making it
more important that both antennas are on the same level ground or
angled appropriately.
With directional antennas such as a 19dBi panel we narrow both the
vertical and horizontal planes to create a highly directional beam.
As standard the NVW-250 is fitted with 5dBi Omni directional
antennas for the high power backhaul radio and the secondary radio,
the NVW-150 is fitted with 3dBi antennas. These antennas provide a
wide (almost spherical) signal spread so are ideal for cases when the
secondary radio is to be used as a local access point and the primary
radio is used to link two NVW units over moderate distances without

18
Datavideo Technologies Co., Ltd
www.datavideo.info
accurate alignment, or in cases where the NVW units will be moving.
For longer range deployments we offer two optional antennas;
19 dBi Dual Polarised Panel Antenna
This directional antenna is ideal for linking two NVW-250 units (Point
to point) over longer distances, its 25 degree horizontal beam width
and dual polarisation (horizontal and vertical) greatly simplify
alignment and allow dual stream data rates to be used increasing
throughput. When used in conjunction with the standard 5dBi
antennas on the secondary radio of the NVW-250 (used as an access
point) this combination allows very long range links while still
allowing client devices to roam freely within the local access points
range.
8 dBi Omni-Directional Antenna
This Omni-directional antenna is ideal for linking two or more (Point
to Multipoint) NVW-150 / NVW-250 units over longer distances. Its
360 degree horizontal beam width allows the unit in Access Point
WDS mode to be located in a central location and have many more
units in station WDS mode located around it. This antenna is also
ideal for situations where the units may be moving but will stay on
the same ground level.
Antennas and WiFi Power Limits
It is important to ensure that you obey local regulations relating to
the permitted transmit power of WiFi devices. In the later sections of
this manual you will see that by selecting your country of residence
the device will automatically ensure it is using only permitted
frequencies and a legal transmit power, however this is only the

19
Datavideo Technologies Co., Ltd
www.datavideo.info
transmit power at the antenna port you may need to further
decrease the transmit power to stay within regulatory limits
depending on the antennas used.
The limits for the UK are:
5Ghz Band B (5470-5725MHz) - License free use up to 1000mw
30dBm (EIRP)
2.4Ghz (2.412GHz ~ 2.472GHz) – License free use up to 100mw
20dBm (EIRP)
The EIRP power (Equivalent isotropically radiated power) is the
combined emitted power of the radio and the gain of the antenna.
For example for 5Ghz if the device has a transmit power of 20dBm
basic theory tells us you can use an antenna no stronger than 10dBi
gain (20 +1 0 = 30dBm EIRP). In reverse if you have a 19 dBi panel
antenna the devices transmit power must be restricted to
approximately 11 dBm (19 + 11= 30dBm EIRP). However in reality
you are allowed to take the loss from the cables and connectors into
account, our wireless link calculator (Available to download) will
help you to make these calculations.
Aggregate Power (MIMO)
The above examples assume only one transmit chain (antenna),
when transmitting with multiple chains we must take the aggregate
transmit power into consideration (See data sheet for aggregate
power values). The aggregate transmit power only needs to be
considered when using 802.11N data rates that use multiple streams

20
Datavideo Technologies Co., Ltd
www.datavideo.info
(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).
