This chapter gives an overview of the Ericsson Mobile Broadband Router
(MBR) W3x product series.
2.1 Product Variants
The Ericsson W3x product series consist of two models:
• • Ericsson W30 – Data Router
Ericsson W35 – Data and Voice Router
The W3x product series facilitates protected, high-speed Internet access for
multiple users in home and small or branch office environments. It includes
advanced data capabilities such as router and switch functionality, and
provides the users with multiple possibilities for local area connectivity
(Ethernet and WLAN).
With WCDMA/HSPA radio access capability the Ericsson W3x is well
suited to provide broadband data access with data speeds similar to fixed
line DSL services. The data rate is up to 7.2 Mbps and the up-link speed is
up to 2 Mbps.

2.3 W35 – Data and Voice Router
The Ericsson W35 data and voice router incorporates the same set of
functions and data features as the Ericsson W30. Additionally, this model
also includes high quality voice and fax services via the telephony
interfaces. A broad range of network related services such as Prepaid
Subscription, CLI (Calling Line Identification), Call Waiting, Call Forwarding,
and Multiparty Conference Calls are available.
WCDMA/HSPA radio access is well suited for combined and efficient data
and voice transmission over the mobile network.
Figure 2 - Overview of Interfaces on the Ericsson W35
Available services may
vary depending on
operator.
2.4 Feature Summary
The Ericsson W3x features the latest technology, which makes it highly
suitable for everyday broadband services:
• Wireless Broadband Services at Reliable High Speed
The Ericsson W3x uses 3G (WCDMA/HSPA) as primary radio access
and 2G (GSM/GPRS/EDGE) as fall-back.
5
1/1551-CRH 102 168 Uen Rev PB1 2009-03-27
1BW3x Series Overview
• Web-based user interface for configuration of the device with wizard
support.
• Advanced Networking
Supports an advanced local network setup providing IP routing,
Ethernet switching, DHCP service, and NAT.
• File and Printer Sharing
Network file and printer sharing is supported through a USB connection.
• Local Wireless Access with High-level Security
The Ericsson W3x may function as a WLAN access point for the
wireless local network supporting WEP, WPA, and WPA2 with preshared keys for WLAN security.
In addition to the above, the Ericsson W35 also includes the following
features:
• Voice Services
The Ericsson W35 includes voice capabilities accessed over standard
analog telephone line interfaces. Network services such as Prepaid
Subscription, Caller ID, CLIP, Call Waiting, Call Forwarding, and
Multiparty Conference Calls are supported.
• Fax Service
The Ericsson W35 supports fax over IP (T.38) functions using packet
switched connection. If T.38 Fax is offered by the service provider as a
service with the Ericsson W35, simply connect an ordinary fax machine
to the “Phone/Fax” connector on the back of the unit and the fax will
work without further configurations.
• Battery back-up
For voice back-up purposes, an optional (available as an accessory)
rechargeable battery-pack can be connected between the AC/DC
adapter and the Ericsson W35.

3 Configuration and Management
When the physical installation of the Ericsson W3x is finished (as described
in the Quick Installation Guide), the internal Web User Interface (WUI) is
available for configuration and status control.
This chapter provides detailed information about configuration options and
management of the Ericsson W3x using the WUI.
The WUI is available in five languages; English, German, Spanish, French
and Italian. Each page in the WUI includes language code buttons for the
supported languages:
Click on a button to change to the preferred language.
3.1 Access and Login to the Web User Interface
The WUI can be accessed locally from a PC connected to either an
Ethernet LAN port or to the Wireless LAN interface.
Note: First time setup must be done via an Ethernet port as the Wireless
LAN interface in the Ericsson W3x is disabled by default.
When accessing the web pages, the following web browsers are supported:
• Internet Explorer® 5.0 or higher
• • Safari® 1.3 or higher
Firefox® 1.0 or higher
• Opera® 8 or higher
Start a web browser on a PC connected to the Ericsson W3x and type
http://mbr or http://192.168.1.1 in the Address (URL) field.
Note: If you change the internal IP address (192.168.1.1) on the Ericsson
W3x, you have to use the new address to access the web pages.
A start page is displayed in one of the following appearances depending on
the operational status of the Ericsson W3x described in section 3.1.1 and
3.1.2.

3.1.1 Enter PIN Code
The SIM card contains information about the subscription and is normally
protected by a PIN (Personal Identification Number) code and a PUK
(Personal Unblock Key) code.
Normally, you have to enter a PIN code to activate the SIM card. In some
cases, however, PIN authentication is not required and it is possible to use
the SIM card without entering a PIN code.
The Enter PIN code page is displayed if a PIN code is required:
Figure 9 - Enter PIN code page
Enter the PIN code (provided with the SIM card).
You can also check “Remember my PIN” to have automatic SIM
authentication in case of a system restart.
Click the Apply button to save the settings.
3.1.2 Enter Password
If a PIN code is not needed for SIM authentication, or if automatic SIM
authentication is enabled, the Enter password page is displayed:

3.3 Wireless LAN Configuration Wizard
The Ericsson W3x may function as a WLAN Access Point (AP) for the local
network providing wireless client(s) with Internet and LAN access. The
Wireless LAN Configuration Wizard guides you step-by-step through the
basic setup for the Wireless LAN (WLAN).
Note: The wireless setup typically requires configuration of both the
Ericsson W3x and the wireless clients. For more information about
configuring wireless clients, see 6.2 – Wireless LAN Settings.
Click the Configuration Wizard… button on the Overview page to start the
wizard.

3.3.2 Network Name
All clients on the local wireless network share a common Service Set
IDentifier (SSID) or network name. This name is required to establish
connection between the Ericsson W3x and the wireless client(s), and to
distinguish the wireless network from any other(s) that may be in use
nearby. Only devices configured with the same network name as the one
set on the Ericsson W3x can obtain access to it.
Figure 15 – Wireless LAN: Network Name (SSID) page
The network name is case-sensitive (distinguish between uppercase and
lowercase letters) and can be changed to any combination of numbers (0 –
9), letters (a – z), and hyphens (-) with a maximum length of 32 characters.
If the “Enable SSID broadcast” option is selected, your local wireless
client(s) will find the network name when scanning the air. If not, the
network name is hidden and has to be manually provided to the wireless

3.3.3 Wireless LAN Authentication
All communication on the wireless LAN can be protected from potential
intruders and eavesdroppers through standard authentication and
encryption methods.

Authentication is used to restrict access to the wireless network and
encryption is the translation of data into a form that cannot be easily
understood by unauthorized users. The encrypted data can only be sent
and received by users with access to a private encryption key.
Note: Make sure that the operating system(s) and Wireless LAN
interface(s) of the wireless client(s) support the selected
authentication method.
Figure 16 – Wireless LAN: Authentication page
Select one of the authentication methods from the “Authentication” dropdown list. The available options are as follows:
Open (No security);
f you select “Open” as authentication method no client configuration is
needed but be aware of that the WLAN will now be open without any
kind of security.

• • WEP-64, WEP-128 (Low security);
WEP (Wired Equivalent Privacy) is considered to be a low security
option. WEP encrypted data is translated into blocks of either 64 bits
length or 128 bits length.
WPA, WPA2 (High security);
WPA (Wi-Fi Protected Access) and its successor WPA2 are the most
reliable security options. WPA encryption uses the Temporal Key
Integrity Protocol (TKIP) while WPA2 encryption follows the Advanced
Encryption Standard (AES). AES offers a higher level of security and is
approved for sensitive corporate and government data transmission.
