Consider now, in the below example where dynamic RF speed selection is enabled. Now that the receiving radio can adjust
its RF speed dynamically, a faster RF speed can be chosen for normal operation. Even though the faster RF speed will not
provide 20dB of fade margin, the system is still reliable because dynamic speed selection will drop down in RF speed when a
signal fade occurs.
Part D – Feature Detail
• Multiple different RF speeds can be
utilised simultaneously, as dictated by
the site distance from the base station.
• Each site will operated at the fastest
possible RF speed.
• Older technology can only operate at the
same fixed RF speed, normally dictated by
the site requiring the longest range.
• All other sites are compromised by having
to operate at the slower RF speed
Dynamic Speed - No Obstructions
Old Technology - No Obstructions
