The Ericsson W20 has primarily been designed to be wall mounted.
Always select an indoor location, preferably close to a window and
the ceiling which generally will give the best conditions for both the
mobile network and wireless LAN.
For best results, place the Ericsson W20 away from microwave
ovens and other transmitters (e.g. security/alarm systems) as they
can cause signal interference.

The Ericsson W20 connects to the UMTS mobile network, and if it is
not available the GSM network is used as fall-back. The UMTS/GSM
signal quality available at the Ericsson W20 location affects the
performance of the unit.
The signal quality can be verified on the Ericsson W20

If you experience poor reception quality, an external antenna (indoor
window or outdoor roof mounted) may improve reception. Such
antennas are available as accessories for the Ericsson W20.

The Ericsson W20 is mounted to the wall using two screws and the
two mounting slots on the unit.
Insert and secure two screws in the wall at a distance of 110 mm.
Leave a space of approximately 3 mm between the surface and the
bottom of the screw heads. Slip the Ericsson W20 slots over the
screw heads and pull down until the unit is seated securely.
