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-multi­point 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).

Datavideo Technologies Co., Ltd
www.datavideo.info

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 NVW­150 / 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).

21
Datavideo Technologies Co., Ltd
www.datavideo.info

Please Note: When the NVW-250 unit is powered via POE the
internal power switch must be in the OFF position for the unit to
function, the power output cannot be used in conjunction with POE.

*PoE Kit Sold Separately

Power Output

When running from battery the NVW-250 also offers a power output
port for powering external devices. The power output provides a
regulated 12V 5A feed. The power output socket uses industry
standard 4 pin XLR connectors (Pin 1 GND, Pin4 V+)

An optional power output cable is available offering XLR to 2 pin

Lemo, 3.1 and 2.1mm barrel connectors.

Antenna Alignment

The antenna alignment must be considered to ensure that the signal
is strong. Remember that the height of the antennas above the
nearest obstacle is critical and increases with longer distance links
(As a general rule you should get the antennas as high as possible).

To gain a better understanding of the antenna height required for a
given distance please use our Wireless Link Calculator (Available to

download).

If using the devices supplied Omni directional antennas alignment is
not so critical due to their wide signal spread however you should
make sure that both units antennas are angled the same (to avoid a
polarity mismatch). If an antenna is angled on one NVW unit it
should also be angled on the other.

22
Datavideo Technologies Co., Ltd
www.datavideo.info

Sometimes angling the antennas slightly will help throughput when
using multi stream data rates by separating the two signal paths.
Likewise when using a single stream data rates multiple antennas can
be angled differently to cover the change between horizontal and
vertical polarity and help reliability (the unit will monitor all antennas
and send/receive on the one with the best signal). See the
‘Aggregate Power (MIMO)’ section on the previous page for more
information.

When using our optional directional panel the antenna radiates
towards the front of the unit. The unit should be installed in a
position whereby the front of the unit faces the direction you wish to
send the signal to (the receiving antenna). To make alignment easier
both units can be connected when at close range allowing the LED

23
Datavideo Technologies Co., Ltd
www.datavideo.info

signal indictors to be used when aligning over a larger distance (Only
devices in station or station WDS mode will display signal strength).
Our panel antenna is dual polarized, this means it contains two
antennas one is vertical and the other horizontal and allows two data
streams to be sent over great distances without interference
between the streams (because of the horizontal and vertical
mismatch)

Info

When the antennas are at the same height, it is quite
simple to align the antennas. However, when the
antennas are at different heights, greater care has to
be taken.

Advanced Configuration

The unit is configurable through any standard web browser. After
connecting your computer to the units Ethernet port using the
supplied RJ45 patch lead you need to assign an IP address to your
computer so that it is in the same subnet as the NVW unit. The units
default IP address is 192.168.168.1 so you must assign an address
within the 192.168.168.x range (192.168.168.2 to 192.168.168.254).

1. Launch your Web browser (Internet Explorer, Firefox,

Operators can change the ESSID, regulatory country code, wireless
profile, channel spectrum width, frequency, data rates, transmit
power and rate aggressiveness.

Wireless Mode

There are 5 modes available.

Access Point

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. Devices in Station mode can connect
to a device in Access Point mode.

27
Datavideo Technologies Co., Ltd
www.datavideo.info

Station:

This is a client mode that can be connected to a device in Access Point
mode (or any other wireless access point/router). It is used to bridge
the wireless connection to an Access Point, this mode forwards all the
traffic to/from the network devices attached to the Ethernet
interfaces. This mode translates all the packets that pass through to
its own MAC address, thus resulting in a lack of transparency.

Access Point WDS (Recommended)

WDS is the acronym of Wireless Distribution System. This mode can
be connected to another device in Station WDS mode. Using WDS
protocol, it allows a client or station device to bridge wireless traffic
transparently. This is the most commonly used mode to connect two
NVW devices.

Station WDS: (Recommended)

WDS is the acronym of Wireless Distribution System. This mode can
connect to a device in Access Point WDS mode. It enables packet
forwarding at layer 2 level and unlike Station mode, it is fully
transparent. This is the most commonly used mode to connect two
NVW devices.

Note: The WDS protocol used is not defined as a standard, thus
compatibility issues between equipment from different vendors
may arise.

Repeater WDS

This mode consists of a device in Station WDS mode and a device in
Access Point WDS mode. The Repeater WDS must first link up with a

28
Datavideo Technologies Co., Ltd
www.datavideo.info

device in Access Point WDS mode, then it can link up with a device in
Station WDS modes. It acts as an extension to the link, more
Repeaters can be added as necessary.

Note : The ESSID must be the same for the Remote AP and the Local
AP. The channels used by the Repeater to link to another Repeater
will follow the selected channel on the device in Access Point WDS
mode.

Access Point Parameters Settings

Local AP-ESSID

This is the Service Set Identifier used to identify this units wireless
LAN. It should be specified while operating in Access Point or Access
Point WDS mode.

All the client devices within its range will receive broadcast messages
from the access point advertising this SSID.

Hide SSID:

Once checked, this will disable advertising of the SSID of the

29
Datavideo Technologies Co., Ltd
www.datavideo.info

access point . This option is only available in Access Point, Access
Point WDS and Repeater WDS mode only.

Country Code

Different countries have different power levels and also
frequency selections. To ensure the devices operation follows
regulatory compliance rules, the operator should make sure that
correct country code where device will be used is selected. The
channel list, output power limits, IEEE 802.11 and Channel
Spectrum Width modes will be tuned according to the regulations
of the selected country.

No Country Set:

Option when checked, only the frequency ranges are available.

802.11n 2.4GHz - 2412-2462MHz, 802.11n 5GHz - 5180-5320MHz
and 5745-5825MHz.

Wireless Profile:

NA is 11n 5GHz band and represents a mix of 802.11n and 802.11a

modes.

NG is 11n 2.4GHz band and represents a mix of 802.11n, 802.11g and

802.11b modes.

Channel Spectrum Width

20M represents the data transmitted at a bandwidth of 20MHz.
20/40MHz represents the data transmitted at either 20MHz or
40MHz. In very noisy environments the NVW unit will automatically

30
Datavideo Technologies Co., Ltd
www.datavideo.info

fall back to 20MHz to be more resilient to the interference. In a
situation when auto fall back does not happen, manually changing
the channel spectrum width to 20MHz will

to help

reduce
interference on the link and improve performance. 10Mhz and 5Mhz
widths can also be used to further reduce interference and improve
range, please note however that a 10Mhz width will provide
approximately ¼ the throughout at 20Mhz and a 5Mhz width will
provide approximately ¼ the performance. (Only supported between
other units with 10/5Mhz support, all connected units must be
configured with the same channel width)

Note: 40MHz bandwidth is non-standard for 802.11n/g mode, if you
experience unstable performance change the channel width to
20Mhz.

Guard Interval : Guard band between packets. For long distance

connections, select Long for improved performance over longer
ranges.

Channel – Frequency

This is the frequency you can set for device to operate within. The
frequency range available depends on the country domain you select
in Country Code. For 5GHz

frequency ranges some have DFS
characteristics earmarked by regulations. Selecting one of these
frequencies for operation may affect and delay of 2 minutes or more
(possibly up to 10 minutes in some situations) for device to attempt
to establish a connection.

Auto: When checked, during startup the device will automatically
select the least interfering channel (or frequency) for operation.

Data Rate

Data Rates consist of both the legacy rates and the MCS
(Modulation Coding Scheme – Only for 802.11n) rates.

6 – 54Mbps are Legacy 802.11a rates

MCS0 to MCS7 are 802.11n rates, which uses only 1 stream.

MCS8 to MCS15 are 802.11n rates, which uses 2 streams.

Auto: When enabled the data rate will be selected based on an

advanced rate algorithm that takes into consideration the amount of
errors at the data rate and fine tune to the best data rate it can use.

The data rate has a critical impact on performance as generally lower
data rates are more immune to noise while higher rates are less
immune, but are capable of higher throughput.

Transmit Power

The maximum transmit power displayed is determined by the country
code and the selected radios maximum transmit power.

Note: When the operator changes the channel, if this new

frequency has a higher permitted power output the power

previously selected will remain unchanged. You need to readjust the

power level to in order to take advantage of the higher output
power available.

Maximum : checking this box will result in maximum TX output
power overriding regulation.

Obey Regulatory Power : checking this box will obey TX output
regulatory power by country.

Rate Aggressiveness

Allows user to reduce or increase the aggressiveness of the fully
automatic algorithm. There are 2 scenarios that Rate Aggressiveness
is useful. In a noisy environment lowering the aggressiveness will
ensure better stability, choose from -3,-2,-1. The environment might
be free of interference but the fully automatic algorithm might not
select a high enough data rate, increasing the aggressiveness will
increase the transmit rate and achieve a higher throughput, choose
from +3, +2, and +1.

Station Parameters Settings

Country Code

Different countries have different power levels and also
frequency selections. To ensure the devices operation follows
regulatory compliance rules, the operator should make sure that
correct country code where device will be used is selected. The
channel list, output power limits, IEEE 802.11 and Channel
Spectrum Width modes will be tuned according to the regulations
of the selected country.

No Country Set:

Option when checked; only these frequency ranges are available.

11n 2.4GHz is 2412-2462MHz, 11n 5GHz is 5180-5320MHz and 5745­5825MHz.

Wireless Profile:

NA is 11n 5GHz band and represents a mixed of 802.11n and 802.11a

modes.

NG is 11n 2.4GHz band and represents a mixed of 802.11n, 802.11g
and 802.11b modes.

Channel Spectrum Width

20M represents the data transmitted at a bandwidth of 20MHz.
20/40MHz represents the data transmitted at either 20MHz or
40MHz. In very noisy environments the unit will automatically fall
back to 20MHz to be more resilient to the interference. In a situation
when auto fall back does not happen, manually changing the channel

35

spectrum width to 20MHz will

help

to reduce interference on the link
and improve performance. 10Mhz and 5Mhz widths can also be used
to further reduce interference and improve range. Please note
however that a 10Mhz width will provide approximately ¼ the
throughout at 20Mhz and a 5Mhz width will provide approximately ¼
the performance. (Only supported between other units with
10/5Mhz support, all connected units must be configured with the
same channel width)

Note: 40MHz bandwidth is non-standard for 802.11n/g mode, if you
experience unstable performance change the channel width to
20Mhz.

Advance Wireless

Click Advanced Wireless tab from the menu and select RADIO 1 or
RADIO 2 to open the page below.

44
Datavideo Technologies Co., Ltd
www.datavideo.info

Long Range Parameters Setup

The advanced wireless page optionally lets you optimize the link for a
specific distance. These options are for fixed point to point links only
and should only be used by advanced users.

Long Range Parameters:

Check to enable parameters.

Beacon Interval: (default is 100 MS)

Define the time interval (in milliseconds) for the beacon to be
broadcast. We recommend using the default value.

Distance:

Enter the distance in meters between both devices. Then click
Calculate. The close approximate values for Slot Time, ACK
Timeout, and CTS Timeout will be calculated to achieve the best
possible performance and link reliability.

45
Datavideo Technologies Co., Ltd
www.datavideo.info

RTS Threshold:

The range is 0-2347bytes, or the word “off”. The default value is

2347 which means that RTS is disabled.

RTS/CTS (Request to Send / Clear to send) are the mechanisms used
by the 802.11 wireless networking protocols to reduce frame

collisions introduced by the hidden terminal problem. If the packet
size the node wants to transmit is larger than the threshold, the
RTS/CTS handshake gets triggered. If the packet size is equal to or
less than threshold the data frame gets sent immediately.

Fragmentation Threshold:

specifies the maximum size for a packet before data is fragmented
into multiple packets. The range is 256-2346 bytes, or the word “off”.
Setting the Fragmentation Threshold too low may result in poor
network performance.

The use of a fragmentation threshold can increase reliability because
when sending smaller frames collisions are much less likely to occur,
however lower values will result lower throughput as well. The
default setting of 2346 is optimum for most network use cases.

Acknowledgement Timeout:

The device has an auto-acknowledgement timeout algorithm which
dynamically optimizes the frame acknowledgement timeout value
without user intervention. This is a critical feature required for
stabilizing long-distance outdoor links.

46
Datavideo Technologies Co., Ltd
www.datavideo.info

Distance:

Specify the distance value in miles (or kilometers) using the slider or
enter the value manually. Changing the distance value will change
the ACK Timeout to the appropriate value of the distance.

ACK Timeout:

Specify the ACK Timeout. Every time the device receives the data
frame it sends an ACK frame to the sender (if transmission errors are
absent). If the sender receives no ACK frame from the device within a
set timeout it re-sends the frame. If too many data frames are re­sent (the timeout is set too short or too long) it will result in poor
throughput and performance.

Auto:

If enabled the ACK Timeout value will be derived dynamically. It is
not recommended to use Auto Adjust option for long range links if
the signal level is low or a high level of interference is present. If two
or more stations are located at considerably different distances from
the device in Access Point mode the highest ACK Timeout for the
farthest station should be set at the AP side. It is not recommended
to use Auto Adjust option for Point-to-Multipoint connections.

Noise Immunity:

Check to enable. When enabled the device will automatically adjust
the noise to signal ratio for best performance. In low noise
environments it is recommended to turn off this function.

47
Datavideo Technologies Co., Ltd
www.datavideo.info

Signal Strength Indicator (RSSI):

The default values are LED1 (RSSI value=7), LED2 (RSSI value=15),
LED3 (RSSI value=22), LED4 (RSSI value=27)

Radio Off with No Ethernet:

When checked the unit automatically stops wireless broadcast when
the Ethernet link is down.

Station Isolation:

When checked the device prevents wireless clients on same AP from
discovering other clients. When enabled wireless stations connected
to the same AP will not be able to interconnect on both layer 2 (MAC)
and layer 3 (IP) level. This is effective for the associated stations and
WDS peers also.

Chain Mask Selection:

Available selections are: a) 1x1 Left Chain, b) 1x1 right Chain and c)
2x2 Dual Chain

Selecting 1x1 (Left/Middle/Right) Chain will force the radio card to
operate with 1transmit and 1 receive stream and both transmit
/receive on the left, middle or right port only.

Selecting 2x2 Dual Chain will enable radio card to operate with 2
transmit and 2 receive streams and automatically transmit / receive
on any of the 2 ports.

VLAN Management

Vlan management lets you control and limit the client connections
that can open the devices web page.

Note: Vlan Management works only in tag vlan pass-through mode.
i.e. when Vlan Switch is disabled. When Vlan Switch is enabled or
configured, Vlan Management function stops operating.

Example:

Assuming there are 2 VLAN ID groups, 2001 and 2002 setup on the
device. One entry in the Vlan Management has the Vlan ID 2001 with
masquerade IP address 192.168.168.20, another entry in Vlan
Management has the Vlan ID 2002 with masquerade IP address

192.168.168.10

You can only select one of the 2 entries to be the active Vlan ID and
IP address. If the Vlan ID 2001 group is selected, then only
computers in that Vlan ID group can open the devices web page
using the IP address,

192.168.168.20 if there is no entry in Vlan
Management, there is no restriction. All computers can open the
devices web page by the default IP address setup in Basic Network
page.
