microwaves, large-screen TVs, cordless telephones are also known to affect wireless
signals. Consider the proximity of devices to these objects.
Distance from access points How far a device is from the closest access point plays a
major factor in determining the stability and strength of the wireless signal.
Multiple Access Points "Repeaters" or multiple access points can solve signal strength
problems that may be caused by either distance or loss due to interference.

2.1.7 CHOOSE POWER SOURCE

V-Station 4G and V-Flex 4G devices can be powered by several methods:
Power sources should be:
When planning a system, know the power requirement of each device. If multiple
devices are to share a common power supply, exercise care to avoid excessive voltage
loss on the wires. Voltage loss can lead to communication problems when devices are
talking and/or listening on different ground references.
Voltage loss is directly proportional to wire resistance and the current the wire carries.
Always place the device as close as possible to the power supply and always select a
wire size appropriate for the load. V-Station 4G devices run on DC power between 12.5
and 24 VDC.
Power requirements for all V-Station 4G and V-Flex 4G models are listed below.
