Radio
The Spectra Precision FOCUS 30 Total Station (Robotic version only) has an internal
radio to support robotic operations. The internal radio is a 100 mW radio that operates
in the public free 2.4 GHz band. The radio uses frequency hopping technology to
reduce radio interference and maintain radio communications in even the harshest RF
environment.The Spectra Precision FOCUS 30 Total Station radio baud rate is
115200 bps. This high baud rate reduces the measurement latency, which ensures that
a measurement viewed at the pole is received 100 msec after the measurement is sent
from the instrument.To maintain radio communication with the instrument, the con-
troller at the pole must also be connected to a 2.4 GHz external radio or have an inter-
nal radio (Spectra Precision Ranger).
