Introduction to the Wireless Routers
Wireless Connectivity
To determine which wireless technology is best suited for your application, the following
guideline will give you some indication of the differences in these technologies.
GPRS
GPRS is a basic low speed GSM data service offered by most GSM operators. It has a
basic upload speed of 11kb/s and a download speed of around 44kb/s. Although GPRS is
very reliable and almost universally available where GSM exists, it has a major drawback of
relatively long latency times with an average latency of around 700 – 900mS. GPRS is ideal
for telemetry applications (meter reading, remote monitoring of devices etc.) or low speed
transaction based systems such as ATM’s but it is unsuitable for video links.
EDGE
EDGE is an enhancement to GPRS which is effectively four times the speed in both the
upload and download directions (i.e. 176Kb/s down and 44kb/s up). It is however not as widely
available as GPRS, but is capable of providing low to medium grade streaming video due to
the higher bandwidth and lower latency.
UMTS HSDPA
HSDPA is an advanced technology which provides very high speed wireless mobile data.
Current speeds are 7.2Mb/s in the download direction depending on the network’s capabilities.
Because of the above, HSDPA is ideal for almost all applications which need reliable, high
speed networking. Applications include remote signage high quality CCTV and provision of
internet access to areas with no access to wired services.
HSUPA
HSUPA is the latest release of high speed wireless network which offers significantly improved
uplink speeds as denoted by the ‘U’ in the name. Uplink intensive applications such as CCTV
will benefit considerably from this technology.
Wireless Routers
Mobile Router
The Mobile Router is capable of connecting to GSM/GPRS/EDGE networks. Typical applica-
tions are where reliability is important, but high speed is not a priority such as ATM machines,
credit cards authorizations and telemetry.
Broadband Router
The Broadband Router is capable of connecting to UMTS HSDPA / HSUPA networks. Typical
applications include remote office connectivity and CCTV video streaming.

Introduction
Product Features
The Wireless Routers have one RS-232/422/485 Serial interfaces, a integrated EDGE or
HSDPA modem depending on model, dual SIM slots and a single 10/100 Base-T Ethernet
interface.
A Wireless Router is capable of connecting a number of Ethernet devices via GSM/GPRS/
EDGE networks on the Mobile Router, or UMTS/HSDPA networks on the Broadband Router.
With always–on and DUAL SIM card technology they provide easy to deploy access to central
servers and the Internet via GSM networks. The Wireless Routers are capable of maintaining a
permanent PPP connection or alternatively making a connection on demand (dial-on-demand)
to the distant network. It also allows you to dial into an Ethernet network to access devices on
that network or dial out of an Ethernet network to connect to a remote RAS server.
Some of the features supported by the Wireless Routers are:
IP Masquerading, which allows one or more computers in a network without assigned IP
addresses to communicate with the Internet.
Port Forwarding, (sometimes referred to as tunnelling) which is the act of forwarding a network
port from one network node to another, can also be enabled.
The Firewall feature on the Wireless Routers allow you to implement security by setting up
Access Control rules. The Firewall feature allows you to control your connection denying any
unwanted traffic or simply viewing what traffic is passing through the Wireless Routers.
Another feature on the Wireless Routers is a DHCP server to dynamically allocate IP
Addresses to hosts connected to the Ethernet network.
VPN functionality is standard on the Wireless Routers, providing reliable and secure communi-
cation between the Router and your corporate network.

Introduction
Wireless Routers
Security
Securing your Wireless Router is done on various levels. Authentication is required for
configuring the Wireless Routers. The administrator username is ‘root’ with the default
password being ‘xxx’. It is recommended that you change this password to protect against
unwanted configuration changes on the Router.
NOTE: DO NOT lose your password. If both the Bootloader and System passwords
are lost, you will need to send your Wireless Router back to Multenet to be
reprogrammed. There is a cost associated with this recovery procedure. You are
able to recover from a lost System password by erasing the Dataflash using the
Bootloader login. The firmware will then need to be uploaded via serial.
Firmware Updates
Multenet continues to develop its products extensively, with new firmware releases available
regularly. New releases may contain new protocols, new features, bug fixes, performance
improvements, etc.
These firmware updates can be downloaded from the Multenet website:
http://www.multenet.com/support/downloads.html
Alternatively, contact your local distributor or email Technical Support.
Firmware can be uploaded to the Wireless Routers via EtherPAD Explorer V1.5.2 and above
(included on CD).

GETTING STARTED
This chapter provides information on connecting your Wireless Router to the network. The
Wireless Routers operate on the GSM network and it is important to take signal strenth and
quality into account when installing these devices.
