1 INTRODUCTION
The Product
MOBI UTD-W Terminal is built based on the IEEE 802.20 standard combined with 54Mbps
Wireless LAN (WLAN) standard. This WiFi is five times faster than the widely deployed WiFi
(802.11b) products that are found in homes, airport and public wireless hotspots. 802.11g uses
the same 2.4GHz frequency band, this product is fully interoperable with existing WiFi cards and
devices.
Having two wireless protocols in one product is value-add, it enable you to enjoy the fastest
Wireless LAN speed at the same time.
This product combines 4 features:
a. Mobile Broadband Wireless Access (MBWA) with up to coverage 13KM range on a
flat terrain
b. Wireless LAN Access Point (AP) compliant with 802.11b and 802.11g standards.
c. 4-port Auto MDI/MDIX Switch
d. Router with NAT, DHCP Server built-in.
The product is an all-in-one device that allows multiple PCs to share the MOBI UTD-W broadband modem.
It can serve up to 4 Ethernet-PCs and many WLAN-notebooks. The built-in NAT and DHCP
Servers ensure almost plug-and-play convenience for your home network. Advanced features
such as Firewall, DMZ and WPA encryption make this a product equally suitable for your office
use.

Wireless LAN Basics
A Wireless LAN (WLAN) is a computer network that transmits and receives data with radio
signals instead of using cables. WLANs have become common in homes, offices, airports and
public Hotspots. WLAN can support the same applications and software that run on a wired
network (LAN). Besides supporting the same software and functions, WLAN brings greater
convenience and eliminates the need to lay Ethernet cables in a home or office.
The Router is based on the finalised 802.11g standard. The IEEE 802.11g standard is an
improvement on the 802.11b (WiFi) standard. It increases the data rate up to 54 Mbps within the
2.4GHz band. As the 802.11b standard is also using the 2.4GHz frequency band, the product is
fully backward compatible with the older 802.11b devices. WiFi cards can be used to connect to
the Router at 11Mbps.
The Router can even support 108Mbps WLAN if the user is using a recommended Turbo-capable
Cardbus.
The Router is also known as the Wireless Access Point (AP). The PC using the Cardbus is
known as the Client. WLAN networking involves a few additional parameters to be configured:
SSID
The SSID is the “network name” for the WLAN network. The SSID is any name, and can be any
set of characters or numbers, and must be configured on both the AP and Client. The Client sniffs
the radio frequencies for an AP with the same SSID with itself. The client locks onto the AP and
they are “associated”.
To enable plug-and-play convenience, most client cards can sniff the frequencies to extract the
available SSIDs to let the user choose from. Alternatively, setting the client’s SSID to “ANY” can
allow it to connect to most APs regardless of the AP’s SSID setting.
Encryption
WLAN traffic can be captured by anybody to be read! The solution is to use encryption to make
the traffic appear as random characters to the eavesdropper. Both the AP and client must use the
same encryption standard and key to enable them to decode the “rubbish”. If the encryption
settings are mismatched, the client and AP cannot associate. WEP (Wired Equivalent Privacy) is
the most common WLAN encryption standard.
MAC Address Control
Every client card has a unique MAC Address. This MAC Address can be input into the AP
(Router), such that the AP only allows this pool of MAC Addresses to use the WLAN.
Channel
There are a total of 11 channels in the 2.4GHz band. Depending on regulation, not all the
frequencies may be available in every country. Frequency is configured on the AP only. The client
searches for the AP and locks onto that AP’s channel.
Signal Strength
Radio signals drop in power over a distance. Even if all the settings are correct, a low signal
strength makes association impossible. The usable distance between the AP and client can
range from a few meters indoor to 200m outdoors maximum. When setting up the AP, make sure
that you:
Keep the distance from the AP to the clients as short as possible.
Make sure that the WLAN signals do not have to pass through too many concrete walls
and metal structures to reach the client.

Make sure that APs are located far away from one another to avoid interference.
Interference
Interference happens when 2 APs with the same channels are placed near to one
another. The speed of the network drops and the signal strength fluctuates wildly.
Roaming
Association happens when the SSID, Encryption and MAC Address Control settings are
correct between the AP and client. If 2 APs with these same settings are located in the
same area, the client would choose to associate to the one which gives it a better signal
strength. The client would roam over to the 2nd AP when he moves nearer to it. The
client switches AP and frequency as he does so.

5 BASIC IP NETWORKING
Internet Protocol (IP)
IP stands for Internet Protocol. In an IP network, every device has a unique IP Address (For
example: 192.168.1.35) to identify itself. There are two ways of assigning an IP address to a PC
or Router: Static and Automatic (DHCP). Static IP addresses are keyed-in manually, while
Dynamic IPs is distributed by a DHCP Server.
Ports
Every packet of traffic is identified by its Source and Destination Addresses, which would ensure
that the packet arrives at the correct destination. A Port Number is also embedded in each
packet; to identify which software application that generated and uses that packet. Therefore, if
the Router blocks a certain port number, it denies the particular software from using the
connection.
Static IP Address
Static IP addressing ensures that the device will always have the same IP address. Static
addressing is commonly used for your servers.
Dynamic IP Address
A dynamic IP address is one that is automatically assigned to a PC. These IP addresses are
“dynamic” because they are only temporarily leased to the PC when it connects to the network.
This is the most convenient and common way of managing IP addresses in a network. The
Server that manages this pool of IP addresses is called the DHCP Server. The product has a
DHCP Server built-in to simplify the network management.
DHCP (Dynamic Host Configuration Protocol)
The PC obtaining an IP address from the Server is called the DHCP Client. If there is already a
DHCP Server running on your network, you must disable one of the two DHCP servers. Running
more than one DHCP server together will cause network problems!
What is a Router?
A router is a network device that connects two networks together, to let them communicate. All
the PCs in your home or office would be considered to be in one network: the Local Area Network
(LAN). The Internet is considered to be another network: the Wide Area Network (WAN). The
Router serves 2 purposes:
Connect all the PCs in the LAN together, allowing them to communicate with one
another. (File sharing, Printer sharing etc.)
Connect all the PCs in the LAN to the Internet, allowing them to simultaneously surf the
web and access e-mails.
The Router is connected to 2 networks at the same time. Therefore, it has two IP addresses: one
for the LAN, and one for the WAN. The Router’s LAN IP address can be configured, but it is best
to use the default settings. The WAN port is a MOBI PPPoE client by default.
