1. InMotion Web Conferencing
System Requirements
Summary:
InMotion Web Conferencing software is a client/server application. The host and presenter
(client) software requires Internet Explorer, v5.0 or later. Participants (client) need only a web
browser. There are no slide pre-processing, virtual machine, or other client applications to
install.
The minimum server requirement is Windows 2000 or later, 1.2+ Ghz clockspeed, and 256 MB
RAM available for this application. There are NO server software perquisites such as databases
and web servers! The server MUST have port 80 available. InMotion recommends leaving the
default port settings as is for trial evaluation. All presenters and participants must have IP
routing access to the server, and the conferencing server must be on a static IP address
(note: can be physical or mapped, but definitely must be static). For external conferencing,
the server must be located in the DMZ, or co-location, or if behind the firewall, the firewall
must have port 80 open, for in-bound and out-bound communication, and allow ActiveX
(recommended, but not required). These settings should apply to/from the conferencing
server only.
Please see below for additional information and recommended system requirements. Contact
InMotion for assistance with configurations that do not allow ActiveX, require cross-platform
support, or over 100 concurrent users.
Users and Roles:
Please note the different types of users and their roles.
User Types Roles
Server All web conferences require a server where all conference sessions are
hosted. The server is responsible for routing all conference activity between
users. The server also makes it possible to do application sharing, desktop
sharing and remote control between users at different private IP addresses.
Note: InMotion Web Conferencing requires TCP Port 80, and defaults to a
short list of additional ports. See Server page below for details.
The Host is the user that created the virtual conference room and is
Host
responsible for managing the entire session including features and
privileges.
Presenters are allowed to share any document, PowerPoint presentation, or
Presenter
application and activate desktop sharing. The audio and video features are
only usable if authorized by the host.
Participants are users who only have rights to view the presentation. The
Participant
audio and video features are only usable if authorized by the host.

2. Server Hardware Requirements
The InMotion Web Conferencing server is the heart of all conference sessions. It is responsible
for routing all conferencing traffic between users. The InMotion Real-Time routing engine has
been highly optimized over many years of use, it is capable of routing large amounts of traffic
without encountering CPU bottlenecks. System performance is generally governed by the
bandwidth available to each user.
Please contact InMotion Sales for site planning assistance regarding applications with over 100
concurrent users, and/or if have you questions or concerns about these requirements.
Minimum Requirements
• Pentium 3
• 1.2 GHz CPU
• 256 MB RAM
• 10 MBit Network card
• A static TCP/IP address or a routable host name. The address or host name must be
routable for all intended participants.
• Windows 2000 Server w/SP2
Recommended Requirements (50 concurrent users)
• Pentium 4
• 1.8 GHz
• 512 MB RAM
• Fast disk subsystem
• 100 MBit NIC or better
Note: Each connected user will use approximately 1 MB of RAM. Based on this information the
different Windows Server OSes will support:
• Windows 2000 Server:
Standard Edition - up to 250 simultaneous connected users
Enterprise Edition or Better - up to 500 simultaneous connected users
• Windows Server 2003:
Web Edition - up to 50 simultaneous connected users
Standard Edition - up to 250 simultaneous connected users
Enterprise Edition or Better - up to 500 simultaneous connected users
Note: InMotion Web Conferencing is SMP enabled and will take advantage of multiple
processors.
Hardware Requirements for Host, Presenter & Participant
The Host, Presenter and Participant require Windows running IE v5.0 or later. Details below.
The hardware required for the Host and Presenter are the same, because a Presenter has
rights to use all features. The requirements for Participants are lighter, because Participants
only view activities in a conference. In the event the Host enables audio and video for
Participants, then participants will require more up to date hardware (details below).

* The InMotion conferencing client (ActiveX) can select most Windows compatible video devices. InMotion recommends web
cams that are USB 2.0 or Firewire compatible because they reduce the load on the CPU. In addition, PC video capture cards and
other video devices that include Windows DirectX/DirectShow device drivers, version 9.0 or later are supported, providing an
interface to virtually any standard video device.
** All sound cards listed as 'compatible' to Sound Blaster (SB) Live or better will work with the InMotion audio conferencing
feature. These are typically non SB sound cards manufactured after the year 2000 because they offer a more advanced recording
and playback functionality. There are, however, exceptions where some older sound cards will work with our audio conferencing
technology.
*** Due to the technical limitation of some video cards, the desktop acceleration feature works best with NVidia chipset video
cards.
Please note the list of sound card manufactures is quite large so it is not possible for InMotion to list every compatible sound card

Bandwidth Requirements
The amount of bandwidth users require is based on the features selected during the
conference. As a guide, InMotion has compiled some information to help users determine the
amount of bandwidth they need.
Please contact InMotion if there any questions or concerns about the requirements below.

Background information about InMotion Web Conferencing
PowerPoint Sharing
Generally a PowerPoint file is 500 KB to 4 MB per presentation. With InMotion Web
Conferencing the file is sent to the server by the presenter, and then from the server to all
participants. Thereafter, only slide change commands are relayed via the server. PowerPoint
sharing can be done on dial-up connections (56kbps or less). For sizing purposes, use 8 kbps
for presenters and participants (average PowerPoint presentation size divided into 1 hour).
Key note, after initial PPT transmit, traffic is very low.
Application, Browser & Desktop Sharing
Generally same bandwidth as "remote control." For sizing purposes, use up to 300 kbps for
presenters and participants, while under load (user activity). Traffic is much less "lumpy" than
PowerPoint sharing, but there are long periods of no activity and no traffic.
Video Conferencing
Approximately 256 kbps for 320x240 at 20-30 frames/second (H263+ codec); and

5. approximately 56 kbps for 176x144 (small) at 1-5 fps. For sizing purposes, use 256 kpbs for
standard conferencing, 320x240, 6 fps, for presenters and participants (i.e., a good user
experience). Traffic is normally sustained during a video conference.
Note: InMotion is easily capable of boardroom quality video conferencing using industry
standard web cams. When set at full size, 640x480, 30 fps, allow for approximately 384-512
kbps. IT administrators can limit this capability.
WARNING! DSL and other asymmetric internet services may not offer full 256 kbps on the
uplink; presenters that use video (i.e., that encode and transmit video to the web
conferencing server) must have full 256 kbps or better for a quality video conferencing
experience.
Facts about bandwidth
Bandwidth is measured in two areas. First, the amount of bandwidth available for downloads
(a.k.a. downstream), and second the amount of bandwidth available for uploads (a.k.a.
upstream). There is a sizable difference between the amount bandwidth available upstream
and downstream. This is based on several factors:
1. The type of connection a user is using such as 56k, Cable, DSL, Frame, T1 or T3.
2. The variation to the type of service offered by the provider example iDSL, ADSL,
SDSL. In general Cable Modem and DSL connections typically have fast downstream
(around 1Mbps) but relatively slow upstream (200 kbps).
A user behind a T1 connection on the other hand will most likely have 1.5 Mbps downstream
and as much as 1 Mbps upstream. Although these figures are typical, they are not consistent
with providers. As a general rule, the best way to obtain this information is to consult the
provider and as them for this information.
