How to share your 3G Broadband connection
to more than one device.
Creating a LAN
First up, you will need to create a Local Area Network, or LAN,
which is simply a name for bunch of computers and other devices
such as game consoles, WiFi phones, media players and/or printers
all linked together either by cables or wirelessly to share resources
including an Internet connection.
Here's an example of a LAN sharing a 3G Internet connection:
In the centre of the LAN is a Router. The 3G modem (USB in this
case) plugs into the Router and the Router then shares the 3G Internet
connection with other devices on the LAN.
Note: The Router in this case has a built-in Wireless Access
Point so we can connect devices to it either wirelessly or with
cables. Not all Routers have wireless capability.
Other Router Features
Besides having the ability to share an Internet connection and
protect devices on the LAN from Internet hackers, a Router might
have other features and capabilities such as a Wireless Access Point
so other devices on your LAN can connect wirelessly, an ATA (Analogue
Telephone Adapter) for VoIP so you can make and receive VoIP calls*
over your 3G Internet connection, and VPN endpoints for remote connections
into other LANs such as your office when working from home.
* Note about VoIP capability. Some of the products mentioned in
the list below have built-in ATAs
(look for the word "VoIP" in the product descriptions).
You can of course purchase
a separate ATA later such as the Linksys SPA3102, and WiFi or
IP phones do not need an ATA. If you plan on adding either of these
options later, one feature I do advise you look for is QoS
(quality of service). QoS ensures the VoIP data gets priority so
other downloads that might be occurring at the same time don't interfere
with the call quality.

Most routers that support 3G modems also accept other types of
broadband modems such as Cable modems, or might even have a built-in
ADSL modem. These capabilities won't be relevant to you if you're
only ever going to have a 3G modem in the forseeable future but
if you think you might want access to Cable or ADSL one day then
one type of Router might be a better choice for you if there is
more than one type of Router for you to choose from.
USB or PCMCIA?
Another important consideration is the type of 3G modem
you have. There are two basic types:
Some Routers such as the D-Link
DIR-451 can* accept both types but most will only
support one so read the manufacturer's spec sheets carefully.
* Check manufacturer spec sheet for model compatibility.
The Draytek routers in the product list below
support USB modems. Originally the USB port on Draytek routers started
out as print servers and most will still
be labelled "printer" on the back but don't be thrown
off by that. That's still where the modem goes.
Incidentally, it can still be used as a print server if you don't
need it for a 3G modem. Also, the 2910, 2820 & 5510 series can
support a USB hub so you can use it for both a print server and
the 3G modem at the same time. However, this feature is not available
on the 2800 series because it doesn't have the processing power
to cope with it.
3G Router Table
Below is a list of all current routers that support 3G modems*
taken from my Router Review database
with a quick summary of the main features in the description column.
Click the product name for more information about each product or
go to the Router Review database
to refine the search. For example you might only be interested in
routers that have 802.11n wireless capabililty that will support
a USB 3G modem.
* Note: compatibility problems with
3G modems are frequent so it is vital to check the router manufacturer's
modem compatibility list (usually linked in the comments section
you will see when you click each product below for more information)
or consult the manufacturer prior to purchasing. If you cannot get
absolute confirmation that your modem is compatible with the router,
don't buy it!
