2.3.11 POSITIONING
Proper positioning of the M10 units will increase the range of
operation and the ability of the units to
communicate. It is important to position the
M10 units out in the open and away from any
large metal objects such as file cabinets, safes,
storage cabinets, metal walls or walls
containing foil-backed insulation.
To reduce the risk of the unit overheating, do not
place the M10 under boxes, papers or anything that
may reduce airflow.
If you are using the units in an office with metal cubicle walls it will
increase operating range if the units are placed above the cubicle
wall height.
The use of microwave ovens during transmission may reduce data
throughput by as much as a factor of two.
2.3.11.1 Co-Location of M10 Units
If two or more M10 units are co-located at one site, maximum traffic
throughput rates to remote sites may be reduced, especially if the
user is relying on the internal antennas.
The M10 units operate on a single frequency channel. If one M10
unit is transmitting to a remote site while a second M10 is
attempting to receive data from a second remote unit, the
transmitting M10 will normally block receipt of messages by the
receiving M10.
Traffic throughput rates can be improved by providing enhanced RF
isolation between the co-located units at a site. This is best
accomplished by using correctly orientated directional antennas at
each site. Further improvement in throughput can be expected if the
external directional antennas can be further isolated to reduce RF
leakage. This can be accomplished by increasing the physical
separation between the antennas or by locating the antennas in such
