Welcome
The FMT3251 provides enhanced mobile voice and data service within
the building. It delivers high quality voice calls and faster, more reliable
mobile data service. It connects to your broadband Internet service to
deliver extended indoor mobile network coverage. The in-building mobile
phone connectivity, signal quality, and data bandwidth will greatly
improve, especially if the building is in a remote area or out of adequate
mobile phone tower range.
Your FMT3251 can also function as a wireless AP (Access Point),
extending the range of your existing wired network without additional
wiring, providing easy network access to mobile users.
Inside this packaging you will find: the FMT3251, an Ethernet cable, a
stand and an AC power adaptor. The FMT3251 has a zero touch set-up
process. Just install as detailed in this guide and it connects to your
mobile phone automatically whenever your phone is within range.
Before you begin you need to make sure you have the following:
• High Speed Internet service and an available Ethernet LAN port on
your router.
• An available power socket or electrical outlet.

Quick Setup
Installing the Device is simple and can be completed within 5 to 20
minutes. The following instructions will guide you through the Quick
Setup process.
1. Find a central location in your building or office to install the device.
The Device emits a radio signal similar to a Wi-Fi router. The quality of
the coverage you will experience depends on where the device is
located and it should be placed:
• In a central area of your building.
• As high as possible; on top of tall furniture, shelves, cabinets, etc.
To improve coverage the following should be avoided:
Installing near other radio transmitters
Installing near metallic devices such as radiators
Installing near a window
2. Device placement:
The Device should be placed free standing on a flat sturdy surface.

9
First, power up your DSL router. Connect the Ethernet cable to an
available Ethernet port on your DSL/Cable router.
Then connect the other end of the Ethernet cable to the Device LAN1
port. Connect the power adaptor cable into the jack named Power, and
then plug the power adaptor to an AC socket.
After a few seconds the Power status indicator lights up, and the
Ethernet port status indicators on both the Device and the DSL/Cable
router should light up green (flash green). After 60 seconds the Ethernet
port status indicator light on the Device will automatically shutdown.

10
For free standing installation, place the Device in the stand as shown.
3. Broadband Connectivity:
After approximately two minutes, the Device Internet status indicator
will begin to pulse.
4. Automatic Software Update:
After the device establishes a broadband connection to your Internet
Service Provider (ISP), the Device automatically updates its software.
This process takes about 15 minutes and the Internet status
indicator pulses during this period.
After the device retrieves its software update package, it reboots
automatically.
During reboot, the Power status indicator is on.
5. Auto-configuration:

11
After rebooting, the Device automatically configures itself with the
information you have provided to your ISP and mobile phone operator
regarding phones or devices that are allowed to connect to your small
cell service.
The Internet status indicator pulses and remains on white when the
auto configuration is complete.
When the device is ready to be used, the Internet and Small Cell
Service status indicator are ON white stable. If this does not happen,
go to the Troubleshooting section on page 16 for help.
You are now ready to make your first call using your Device.
Set Up a Wireless Network
The wireless LAN on your Device is enabled by default. To add a
wireless client to the network, use the settings found on the rear panel of
your Device, which will look similar to the following example:
Configure wireless devices that you want to connect to the wireless
network to use the same wireless settings as the Device.
The default wireless settings vary for each Device. Refer to the rear
panel of your device and use the provided information.

12
Final Checks & Making Your First Call
Authorized Users
The Device is configured to only allow service for authorized mobile
phones. The first mobile phone SIM card (the details for which you
provided to your mobile phone service provider) is pre-configured to
work with the device during auto-configuration. To allow other users to
connect to your Device, you must register them with your mobile phone
service provider. The Device will only support service to mobile phones
registered for use on the same mobile phone network as the Device.
To add additional mobile users to your Device please contact your Small
Cell Service Provider.
Mobile Phone Requirements
3G compatible mobile phone.
Enable and configure 3G service on your mobile phone. Details can be
found in your mobile phones user guide.
Enable 3G service with your mobile phone Service Provider to work with
the SIM card in your mobile phone.
Making Your First Device Small Cell Call
Before you make your first call, make sure that your mobile phone is
registered with your small cell service and connected to the Device.

13
Power OFF your mobile phone if your mobile phone was ON during the
Device installation process. Wait 30 seconds and then Power On your
mobile phone.
After a couple of seconds your mobile phone should indicate that it is
connected to the Device small cell. If this is not the case please see the
Troubleshooting section on page 16 of this guide.
You are now ready to place your first call - just use your phone as you
normally do and enjoy the enhanced quality experience!

14
Frequently Asked Questions (FAQ)
How do I know that I am using my Device service?
Your mobile phone display will automatically indicate if you are within
small cell signal range. If registered and configured properly, your mobile
phone should display a small cell service message and an associated
signal indicator.
Will my call drop if I leave Device in the middle of a call?
If you move out of range of the Device Small Cell, your call will be
automatically transferred to the next available network service offered by
your mobile service provider (carrier), without disconnecting your call. If
no other mobile network is available, your call will be disconnected.
How many people can use the Device at the same time?
Up to 8 simultaneous calls can be supported by the Device. However,
the quality of your broadband connection may impact the number of
simultaneous users the Device can support. The Device will
automatically adjust the number of allowed calls in order to ensure that
quality of service is maintained. If 8 simultaneous calls are active and a
9th person tries to connect, the call will automatically be transferred to
the mobile network (assuming coverage from the mobile network is
accessible in your Enterprise) and the Use status indicator will flash.
What happens if my broadband connection fails?
If you lose your broadband connection, due to IP connectivity setup
failure, the Internet status indicator will flash and your Device
coverage will stop. The Device service will return when the broadband
connection is recovered.

15
What happens if my Device stops operating - can I still place a call?
If your Device stops operating (e.g. if you have lost your broadband
connection) then you will no longer be able to place calls through the
Device. However, if you have coverage from the mobile network of your
mobile service provider you can still place calls normally.
Why can’t I access the Device or ping any computer from the WLAN?
Check if the wireless adapter on the wireless station is working properly.
Make sure the wireless adapter installed on your computer is IEEE
802.11 compatible and supports the same wireless standard as the
Device. Make sure your computer (with a wireless adapter installed) is
within the transmission range of the Device.
