Technologies core system consists of a RF (radio frequency)
transceiver, which is the component that sends and receives the wireless signal.
─ The system offers services that enable the connection of devices and the
exchange of a variety of data classes between these devices.
─ The system operates in an unlicensed radio band. It also incorporates the use
of a broadband spectrum which allows the signal to hop from one frequency
band to another.
─ If a band is being used, or is “noisy,” then the wireless signal switches to a
band that is not being used by other RF devices, or has less interference.
─ This “hopping” also provides a high level of security, since with ever-changing
output, it is difficult for external devices to isolate or “pirate” the signal.
─ It checks frequency bands 1600 times per second.
Acquisition and Operational Transmission Ranges
The BlueLine
has an acquisition range of approximately
fifty feet
(
50’
), with
an operational range of up to
one hundred feet
(
100’
).
─ Acquisition Range is the area where the platform and Indicator’s signals are
“paired” or find each other.
─ Operational Range is the area where the floor scale and Indicator operate
after “pairing” has occurred.
If the signal is lost because the floor scale and Indicator are outside of the
operational range (or due to interference), then the operator brings the display
back within the acquisition range.
The intuitive BlueLine
reacquires the signal automatically.
