Installation
LAN configuration requirements
To activate your AT&T MetroCell, it must be able to
communicate with a dynamic Internet address in the AT&T
Mobility network. If you're connecting the MetroCell to
a router that has a simple configuration and hasn't been
customized, you likely won't have to make changes to your
router settings.
• If you have customized your router configuration or are
using a firewall, please consult the LAN configuration
requirements in Appendix A, as well as documentation from
your router manufacturer and/or Internet Service Provider.
Make sure that there is an available Ethernet port on
a router or Ethernet switch with sufficient available
bandwidth to support the traffic that will be carried over the
MetroCell. See Appendix B for bandwidth guidelines.
Serial number
Record the 10 or 11 digit serial number before mounting the
MetroCell. You will need this identifier during Activation.
It can be found on the MetroCell label on the front of the
device (you may have to remove the cosmetic cover which
snaps over the body of the MetroCell), and also on the
shipping label.

Site-specific hardware
All site-specific installation materials such as screws and
wall anchors are the responsibility of the installer and are
not included in the MetroCell packaging.
Placement guidelines
The AT&T MetroCell is intended for indoor use only.
The following are guidelines for placement
of the MetroCell:
• Install the MetroCell in a central location, relative to
the desired coverage area.
• The MetroCell should be installed on an interior wall
or column near the ceiling.

Figure 4 – MetroCell - Indoor Installation Example
• Do not install the MetroCell close to metal obstructions
such as heating and air-conditioning ducts, large roof or
ceiling trusses, and major power cables.
• Walls between the MetroCell and users will reduce signal
strength. Solid metal or metal mesh can block a radio
signal entirely. Signals can typically penetrate one or two
solid concrete walls, three or four cinder block walls, five
or six drywall or wood walls.
• Avoid installing the MetroCell within a few feet of
microwave ovens, cordless phones, fans, motors, and
fluorescent lighting.
• The MetroCell should not be mounted where any person
will spend more than a minute within a 12-inch radius of
the device when it is active. See Appendix E for additional
details.
• Locate the device in a spot which will permit the GPS
Antenna to reach an exterior window, glass wall or door
to receive GPS signals. If the device is unable to receive
a GPS signal, it will not be able to complete activation. If
multiple MetroCells (maximum of 3) are to be installed
at the same address and are provisioned in a single
"Group", only one of them needs to have its GPS antenna
reach a window, depending on placement and building
construction. The GPS antenna cable included in the kit is
25 feet long. A 70-foot extension is available if needed -
ask your AT&T representative.
• The MetroCell kit includes 150 ft. of shielded Cat5e
Ethernet cable. Select a location for the MetroCell that
is within 150 ft. of the router or switch port to which it will
be connected. If necessary, the MetroCell can be as far
away from the router or switch as 300 ft. If a cable longer
than 150 ft. is required, customer must provide this cable,
which must be shielded Cat 5e with metallic "boots". In
the case of installations performed by AT&T, AT&T will
provide the longer cable.
• The MetroCell being installed should be 50 to 100 feet
away from any other MetroCell or MicroCell in the same
building. See Appendix C for additional information on
installing multiple MetroCells.

required between the key components:
