Range is Inadequate
Antenna placement is the most common cause of poor range. Check that the RF power level of the master
and slave units is on “High”. Radio signals in nearby bands that have significant power can also reduce range.
Longest range will always be achieved by Line-of-sight antenna placement. Any obstacle that interferes with
LOS will reduce the range. Particularly bad blocking is caused by metal buildings, solid concrete walls, and
anything else that has fairly high electrical conductance. Raising the antennas higher can help. Sometimes just
moving the antennas sideways will find an RF “path” that will improve distance. The CellScale can sometimes
take advantage of reflecting surfaces to get around obstacles. Antennas should always be place in vertical
polarization, that is the shaft of the antenna should be perpendicular to the earth, not parallel. It is OK to mount
the Antenna upside down. This is a good solution when an antenna is mounted on the ceiling for communication
with CellScale components in the building.
