Network Deployment Guide for NovoPRO
NovoPRO is a wireless presentation and collaboration system designed to support highly
interactive and collaborative meetings or classroom learning activities. Meeting participants,
instructors, teachers and students can interact and share digital content via their PCs, tablets,
Chromebooks and smartphones —a true BYOD device.
To fully take advantage of NovoPRO’s capabilities, it should be properly deployed in a school or
corporate’s network. Some aspects should be carefully considered and planned, for example,
WiFi interference and channel selection, intranet firewall, Bonjour protocol support across
different subnets/VLANs, Quality of Service and device management. In this whitepaper, we are
going to illustrate these points one by one to facilitate a successful NovoPRO deployment in your
network.
1. Network Connection
NovoPRO has three network connection types, Ethernet, WiFi Client, and WiFi Hotspot.
A) Ethernet –NovoPRO can be plugged into your Ethernet via its RJ45 port. Namely, you
can connect NovoPRO to your organization’s backbone network. It is recommended
to use Ethernet connection (when possible) since it gives you better robustness and
higher performance.
B) WiFi –NovoPRO’s built-in 802.11ac WiFi operates at dual bands (2.4/5GHz). With its
2T2R antenna, it can achieve a maximum bandwidth of 300Mbps
1
. This high-
performance WiFi module can operate at two modes.
a) Client Mode –NovoPRO can be connected to your organization’s WiFi network
via its built-in WiFi module.
b) Hotspot Mode –NovoPRO can creates its own WiFi network, allowing users to
connect their mobile devices to this ad hoc network.
The following table summarizes their feature difference and typical usage.

It is worth mentioning that Ethernet and WiFi connections can coexist on NovoPRO. Namely, you
can configure NovoPRO in Ethernet and WiFi Client mode, or in Ethernet and WiFi Hotspot mode.
1.1. Ethernet
The following home screen shows NovoPRO is in Ethernet mode, where its Ethernet IP is
highlighted in a red box.
When connecting to a wired network, NovoPRO supports both DHCP and Static IP connection
types.
DHCP: NovoPRO obtains its IP address from the DHCP server on the network.
Static IP: NovoPRO is assigned a fixed IP address manually.
“DHCP” is the default connection type. However, “Static IP” might be more preferable as it makes
remote management much easier.

The following diagram illustrates how to select one of these two connection types. (Settings 
General Settings Ethernet Ethernet Configuration).
To set up “Static IP” properly, you
need to have the following
information, as shown in the diagram
on the right.
An unallocated IP address;
Netmask;
DNS address;
Gateway address.
1.2. WiFi Client Mode
In this mode, NovoPRO functions as a client to join an existing WiFi network. As illustrated in the
following diagram, to set up the WiFi connection, on NovoPRO home screen, click on button WiFi

Connect to WiFi Configure Wi-Fi (ON). Then select the desired Wi-Fi SSID (the name
associated with the Wi-Fi network) and enter the proper credentials when necessary.
You may notice that you have the choice of using “DHCP” or “Static IP” in the connection dialog,
which is exactly the same as Ethernet connection.
Logging in a WiFi Network via Captive Portal: Some WiFi networks are equipped with a captive
portal, which requires users to log in via a web browser before they can access the Internet.
When a NovoPRO device is connected to this type of network, users can follow the following
steps:
A. Follow the above configuration steps to connect to the organization’s WiFi network;
B. After the WiFi is connected, click on button “Browser”on the home screen (see the
picture below);
C. Open this web browser and you will be prompted for login credentials.
D. Enter the proper username and password, and you will be connected to the network;
E. Click the button “Return Back” on the home screen to return to NovoPRO App main
interface.

Logging in a WiFi Network with 802.1x Authentication:
When you connect to a WiFi network with 802.1x
authentication (for example, radius server), you will need to
enter the following fields to set up the connection properly:
Network SSID Your network
Security 802.1x Enterprise
Choose the right settings for
oEAP method
oPhase 2 authentication
Identity Your username (such as
DOMAIN\John.Smith )
Password Your password
Click on button “Connect” to start the connection.
1.3. WiFi Hotspot Mode
A newly unpacked NovoPRO starts up in Wi-Fi Hotspot mode, where you can start using it without
any entanglement with networking setup. The default SSID for this WiFi Hotspot is “NVC_XXXXX”
(for example, “NVC_4DF8F” in the following screenshot), where “XXXXX” is a device-generated

text string. Please note that Android mirroring (Miracast) is disabled in this mode. In comparison,
AirPlay mirroring has no such limitation.
With NovoPRO firmware V2.2 or above, you can also configure Hotspot’s RF channel and its
routing behavior with LAN. As shown in the figure below,
You can change the RF channel to avoid unnecessary radio interference, as explained in
Section 1.4.
“Enabling LAN-WiFi-Hotspot routing” gives you the option to either keep LAN and WiFi
Hotspot completely isolated, or, allow WiFi Hotspot to piggyback LAN for Internet
access.

In addition, you can change rename WiFi Hotspot SSID and change its security settings (security
protocol and its password.) To do so, click on button Settings General Settings More 
Tethering & portable hotspot. Then the following “Set up WiFi hotspot” window pops up to
allow you to make changes.
1.4. WiFi Network Optimization
One of the most common issues users run into when using NovoPRO is the loss of connection,
which is likely caused by instable WiFi connection. Maintaining a stable WiFi connection is
always a challenge due to the plain fact that it is wireless, subject to noise interference and
physical environment. To keep a good connection, you might follow generic WiFi setup
guideline, such as
1) Don’t place NovoPRO next to electric noise sources, such as electric fan or power
supplies. Especially when you attach NovoPRO next to a projector or an LCD monitor,
you need to keep an eye on these potential “pollution” sources.
2) Make sure you don’t place NovoPRO behind metal frames/bars, etc. Metal will greatly
degrade WiFi signal strength.
3) NovoPRO’s hotspot mode supports devices within 30 meters (100 feet). If you have an
external router, it is recommended to use NovoPRO WiFi client mode instead of hotspot
mode.
4) Try using 5GHz band as it is more robust than 2.4GHz band.
5) Lastly, you might want to check how crowded the WiFi spectrum is occupied. Two
popular Apps can give you a very good view of the WiFi spectrum.
“WiFi Analyzer” on Android devices;
“InSSIDer” tool on Windows OS.
If too many WiFi Access Points occupy the same RF channel, it can lead to sluggish
performance, and, disconnection if it becomes severe. The following example is a
screenshot from “WiFi Analyzer” App. As you can tell, WiFi channel 6 is heavily utilized.
You might want to change one or some of them to other less-crowded channels.

1.5. Dual-network Configuration
NovoPRO can even be set up to support dual networks:
Ethernet & WiFi client mode: connect to your organization’s existing wired network and
wireless network simultaneously. This function is extremely useful for organizations with
“guest” wireless network setup for external visitors.
Ethernet & WiFi hotspot mode: connect to your organization’s wired network and run as
a WiFi hotspot simultaneously. If needed, “LAN-WiFi-Hotspot routing” function can be
enabled to allow all devices connecting to its hotspot WiFi to have internet/intranet
access (via the wired Ethernet connection). You may find this configuration suitable for
meeting rooms.
Ethernet & WiFi client mode
In this case, NovoPRO’s RJ45 port is connected to a wired EMPLOYEE network for employees to
securely access it; at the same time NovoPRO’s WiFi is connected to a GUEST network to allow
visitors to access it. The following graph describes such a network setup scenario.

Network Deployment Guide for NovoPRO
V1.2 Page 9of 16
By doing so, the GUEST and EMPLOYEE networks are kept separated, while at the same time, the
NovoPRO device is available to both guest users and employees.
Notes on Network Security: Within NovoPRO, the WiFi section is completely separated from the
Ethernet section, namely, there is NO network routing between these two sections. Therefore,
users connecting to the WiFi section will not be able to access any resource on the Ethernet at all,
and vice versa. In short, security is not compromised in this configuration.
Ethernet & WiFi hotspot mode
In this case, NovoPRO’s RJ45 port is connected to a wired network connecting to the
internet/intranet; at the same time NovoPRO is also running at WiFi hotspot mode allowing PCs
and tablets to connect to it wirelessly. The following graph describes such a network setup
scenario.

V1.2 Page 10 of 16
As described in Section 1.3, you can enable the routing between LAN and WiFi Hotspot. Once you
enable this routing feature, devices on the WiFi Hotspot side will be able to access intranet or
Internet resources via the LAN connection.
Notes on Network Security: before you enable this routing feature,
1) You may consult your organization IT administrators to avoid compromising your network
security.
2) WiFi Hotspot by default is an open network. It is strongly recommended that you change
it to a secure WiFi network.
2. Port Numbers and Intranet Firewall
NovoPRO is a TCP/IP-network-based device, and the communications between a NovoPRO
device and its client devices (e.g. laptops, tablets, etc.) are achieved through several TCP and UDP
ports. The following table summarizes all the port numbers being used.
