IMUW GENERAL WIRELESS
INFORMATION
- What is A Wireless
Network?
Wireless Network refers to
Wireless Local Area Network “WLANs”,
specifically those supported by the popular
802.11 standards family such as 802.11a,
802.11b, and 802.11g. Another term frequently
used for WLANs is “Wifi”.
A Wireless LAN
is a type of local area network that uses high
Radio Frequency (RF) waves rather than network
cable to communicate between noted.
- How does A Wireless LAN
work?
A
Wireless LAN transmits and receives data over
the air via radio frequency (RF) waves, instead
of the need for wired connections.
In
wireless local area networking, a wireless
user’s will be connected via radio frequency
(RF) to a device called wireless access point,
which is hard-wired to a computer network
itself. The Wireless access point will
broadcasts a wireless signal to the surrounding
area. Any device that is equipped with a
wireless networking card can receive that signal
and communicate with the access point, and
connected to Wireless network after user’s
authentication.
- What is the IEEE 802.11
standard?
IEEE is the Institute of
Electrical and Electronics Engineers, a
standards body that promotes design
specifications to ensure compatibility between
different manufacturer's products. IEEE 802.11,
the Wireless standard, is the IEEE designation
for the particular kind of wireless networking
technology.
- Why we need wireless
network in the IMU campus?
The main goal of
implementing Wireless Network is to enhance the
functionality of the IMU campus network by
extending the network, making our academic
information and online resources available to
our students, faculty members, and staff
anywhere, anytime and the freedom to surf
without wires.
Beside this, it enhances the
flexibility and mobility of users. Staff,
lecturers, and students with wireless-enabled
devices are no longer tied to a fixed location,
they are able to access electronic resources,
wherever they may be in IMU, BJ campus.
In
addition, the Wireless Network also brings
immediate access or convenient access to IMU
online resources. It is to improve the way
people work, teach, communicate, collaborate and
this increase productivity.
- What Wireless frequency or
Wireless protocols are supported by IMU Wireless
Network?
The Wireless frequency or
protocols currently supported by IMU Wireless
Network is 802.11 standard protocol, which
included 802.11a, 802.11b and 802.11g.
- Who may use IMU Wireless
Network?
All staff and students of
International Medical University and IMU
visitor.
- Do I need a Username and
Password to connect to IMU Wireless Network?
Yes, a
username Novell ID
and PIN is required
to access IMU Wireless Network.
For
guest access, please register yourself at IMU,
Helpdesk department to get your temporary
Wireless ID and PIN for accessing the IMU
Wireless Network. TEMPORARY

- How much do I have to pay
for an IMU wireless connection?
Connection to the service
is free-of-charge (FOC) for all members of
International Medical University.
- How fast is the IMU
Wireless Network?
The IMU Wireless Network
maximum can operate at 54Mbps with IEEE 802.11a
or IEEE 802.11g standard. Additionally, it is a
shared access medium. This means it depends on
how many users are connected to the wireless
access point. If there are many people connected
to the wireless access point, the slower the
connection will become.
Besides that,
the encryption transmission will also affect the
wireless speed, but this is important for
wireless security purpose.
- Does the number of
wireless users influence the wireless connection
speed?
Yes, the more users
connected to the IMU Wireless access point, the
slower the connection will become.
- What policies apply to IMU
wireless networks at the IMU?
Please refer the Link
below for more information.
IMUW
Wireless LAN communication policies and
rules
- Why the wireless LAN
network is slower than a wired LAN
network?
The wireless technology
itself is slower, support 11 Mbps and maximum
can go up to 54 Mbps in a shared mood, instead
of 10/100 Mbps (dedicated) for most wired
connections.
In addition, the amount of
wireless bandwidth that you can get is
determined by how strong and "clean" your signal
is, so even though the ICT has made every effort
to provide clear strong signals in marked
coverage areas, there still remains the
possibility of outside interference such as
microwaves and cordless phones which can
drastically affect bandwidth on the 802.11b and
802.11g.

- What IMU Wireless
Networking services are available?
There are 2 type of
IMU Wireless Network services (SSID) available
in IMU campus.
1. IMUS
2. IMUG
IMUS
This service
has enhanced wireless security feature that is
available for all staff and students in IMU
campus. It is more secure compare with IMUG.
Users are
authenticated securely via 802.1X authentication
method (EAP-GTC and EAP-TTLS) with their Novell
ID and PIN. After authenticated successfully,
all network traffic between the wireless devices
and Wireless controller will be encrypted via
WPA or WPA2 encryption methods. With the 802.1X
wireless authentication configuration, it
protects the un-authenticated access and reduce
the risk of security vulnerabilities.
Noted: Due to the security purposed, ICT
highly recommend that all the staff and students
connect via IMUS
with 802.1X authentication method.
IMUG
This service
provides a basic access to World Wide Web
(WWW), with the limitation of wireless security.
This wireless service is applicable to staff and
students, and IMU visitors.
IMUG is the unsecured
wireless connectivity by SSL web page
authentication or captive portal authentication.
Users are authenticated via SSL web page
authentication with their Novell ID and PIN or
their temporary ID and PIN. Once authenticated,
users are able to access IMU wireless network,
but the network traffic transmitted between the
wireless devices and wireless controller are not
encrypted. It means the wireless network is
insecure. People are able to capture your data
over the air.
Due to the wireless security
issues, ICT does not recommend using IMUG for any sensitive
information, such as banking transaction. In
addition, ICT have blocked the user accessing
student netmail via IMUG wireless
connectivity.

IMU helpdesk in order to connect to the IMU
Wireless Network.
A temporary User ID
and Password with a time restriction will be
assigned to users after registration. They will
be able to connect to IMU Wireless Network with
Captive Portal authentication solution, but this
is not a SECURE wireless connection.
Noted: Information sent over our
wireless network without 802.1X authentication
is not secure and is not automatically
encrypted. We do not recommend using the IMUG wireless network for
financial transactions or for items of a
personal or confidential nature. The data that
is not encrypted can be intercepted.
