Modena Hub/Hub+

Network Administrator’s Guide

Modena Hub is a wireless presentation hub

that supports versatility in modern working
environments. Ideal for Bring Your Own Device
(BYOD) and Bring Your Own Computer (BYOC)
spaces, Modena Hub allows participants to
connect to meeting room AV equipment and
USB accessories wirelessly. It also enables any
participant to wirelessly receive AV streams
during a video conferencing session.

This document is intended to guide network
administrators and IT teams in successfully
integrating a Modena Hub system within a
network environment.

General Network Requirements

The Modena system relies on stable and ecient

wireless connections and should be deployed on
a professional, enterprise-grade wireless network
to ensure optimal reliability/connectivity during

a meeting. Specic/recommended network

characteristics are as follows:

Corporate access point

• 802.11ac WiFi5 MU-MIMO 3x3 minimum

• Maximum of 20 active users per access point

The active users limit is valid under good

network conditions as specied under “Wireless

requirements” section below. Otherwise the

number of active users may be signicantly

reduced.

Modena Hub+ integrated access point

• Maximum of 12 active users

• Modena Hub+ access point works well in

ideal network conditions. In crowded Wi

environments, enterprise-grade external
access points are highly recommended.

• Avoid installing the Modena Hub+ directly
behind a TV display, as the display may

disrupt/shield the Wi signal.

A survey system (a Wi analyzing tool) should

be used to evaluate the interference level of the

Wi environment and identify the best channel

available in the network.

Connected Device Requirements

The following gives hardware and operating
requirements for connected devices:

Desktop & Laptop Computers

• Windows and MacOS

- Intel Core i5 - 6th Generation 4 cores
(minimum)

- Intel Core i7 - 7th Generation 4 cores
(recommended)

• Power Saving Disabled

• CPU workload must be below 75% when
running wireless presentation, wireless USB
and video-conference client.

• Capturing resolution may be reduced to
720p from the application settings to address
performance issues.

• Hardware acceleration is not supported with
NVIDIA GPUs (the app can be run selecting a

dierent video card, or hardware acceleration

can be disabled).

Tablets & Smartphones

• Android 8.0 minimum, with hardware
acceleration available.

• iPhone 8 or later

• iPad 5th generation or later

• iPad Pro 2nd generation or later

on the camera model, the resolution can be
automatically negotiated with Modena, or

must be manually congured in the camera

settings.

• For USB cameras, speakerphones, and all­in-one devices, please check the updated

compatibility list.

• If connecting multiple USB devices, typically
a USB camera and a USB audio device, an
active (powered) USB hub can be used to
provide more ports.

• Reboot the Modena Hub each time a USB
device is plugged into the USB port.

Wireless requirements

Wireless Connection

• 2.4Ghz 802.11n compatible Wi interface

• 5Ghz 802.11ac compatible Wi interface

(recommended)

• Minimum distance between device(s) and

Wireless USB feature

• Some USB devices have a longer start-up

time than others; wait until the device boot

sequence is complete before powering on the
Modena Hub.

Using an appropriate tool to measure network
performance is highly recommended. Modena
Hub has an iPerf3 server implementation on­board that can be launched from the Advanced
section of the web admin (see below). iPerf3
is a widely used, cross-platform tool that

can produce standardized performance

measurements for any network, with free clients
available for all major platforms.

Device set up

Modena Hub can be congured from a standard

web browser by connecting to the hub IP
address and entering the web administration
(see Network connection diagrams). To enter the
web admin, navigate to the hub IP address, click
the three-dot menu on the top right of the page
and select the Admin menu item. The default

password is “admin”.

Wired Connection

In this conguration, the Modena Hub/Hub+ base unit is connected to the company LAN via its

Network port. Users connect to Modena via their devices that are connected to the corporate LAN.
These devices may be connected to the corporate LAN wirelessly or via Ethernet connection. Guest
access to Modena can be provided with guest access to the corporate LAN.

Access to Modena and any of its specic features will depend upon permissions granted to the user.

Wired Connection Set-Up

1. Connect Modena’s Network port to
the corporate LAN.

• Make sure the Modena has both

a pathway and access to an active
DHCP server on the network.
Modena is set to DHCP by default
and will need to obtain an IP
address from DHCP server.

2. Connect Modena’s power supply to
power on the unit.

• If power is already connected but

the unit is powered o, press and

release the Power button on the
front of the unit to turn it back
on.

3. Get the Modena’s IP address one of
the following methods:

• Connect a display to Modena’s

HDMI port. The device’s IP
address will be displayed on the

“Welcome” screen.

• Use a network tool to discover

what IP address has been
assigned to the device.

4. Type the device’s IP address into the

URL eld of a web browser to access

Modena’s web admin console.

Stand-Alone Mode (Modena Hub+ Only)

Modena may be congured to function in a ‘stand-alone mode,’ where the wired Network interface

port that would normally connect to the corporate LAN is disabled. Modena has no connection to the
Internet in this mode.

In this mode users can only connect to the system by connecting their device to the wireless access
point that comes built-in to Modena Hub+ models. They will be able to present to the display device
that is physically connected to Modena’s HDMI port and the device screens of any other users that

are connected to the same Modena system via Wi.

Modena’s stand-alone mode is a secure
presentation system isolated from both
the corporate LAN and the Internet.
Users do not have access to resources
hosted on the corporate network or
in a cloud server while connected to
the Modena system. Any presentation

HDMI TV

materials required must be accessible on
the user’s local device.

Stand-Alone Mode Set-Up

1. Make sure Modena’s network port is
not plugged into a network.

2. Connect Modena’s power supply to
power on the unit.

WIFI Hot Spot

• If power is already connected but

the unit is powered o, press and

release the Power button on the
front of the unit to turn it back on.

3. Open the wireless network settings
and connect to the Modena Hub+

network on the computer that

Modena will be congured. Factory

default settings are as follows:

Figure 2. Stand Alone

• SSID: modenahub

• Security: WPA2

• Password: modenahub

4. Get Modena’s IP address on its wireless network. By default, this will be 10.3.2.1. If this setting
has changed, the current IP address can be found in two ways:

• Connect a display to Modena’s HDMI port. The device’s IP address will be displayed on the

“Welcome” screen.

• Use a network tool to discover what IP address has been assigned to the device.

5. Type the device’s IP address into the URL eld of a web browser to access Modena’s web admin
console.

Dual-network mode (Modena Hub+ only)

When congured for dual-network mode, both the wired Network interface port and the built-in

wireless access point will be functional. This allows corporate users to connect to Modena seamlessly
from their device’s regular corporate network connection, while guests can still access Modena via
WiFi without needing access to the corporate network.

This mode oers some degree of
exibility. By changing the “Share

mode” parameter in the Network

conguration page available in the
web admin, it may be congured

for an isolated, secure system or an
open, accessible system.

accessible to users but mutually
isolated from one another.
This means that guests can be
provided access to Modena
without being given any access
to the local corporate LAN or the
Internet. Company users can still
access their corporate network
resources during presentations

• Routing + NAT - Modena Hub+

Figure 3. Dual Network

handles NAT between client
devices on its wireless network and the wired network interface port connected to the corporate
LAN. This allows devices connected to Modena’s wireless access point to access resources on the

corporate LAN as well as the Internet. There is no rewall between the wireless and wired subnets
in this conguration.

• Routing - Modena Hub+ routes trac between devices on its wireless network and the wired

network interface port connected to the corporate LAN, but it does not provide any NAT services.

There is no rewall between the wireless and wired subnets in this conguration. Trac between

the two subnets is handled by the corporate LAN’s routing tables.

• Bridge - Modena Hub+ will congure its WiFi access point as an extension of the corporate LAN

using the same IP address and subnet information as the wired network interface port. Client
devices connecting to Modena’s wireless access point will be virtually connecting to the corporate
LAN.
