67 Tempest®2400 2-Channel Wireless Intercom System
Maximum Number of Collocated Systems
Factors that aect the maximum number of systems that may be collocated in any given locaon include:
• The existence and extent of harmful interference caused by in-band external radiators.
• Number of BaseStaons.
• Number of BeltStaons per BaseStaon.
• Whether or not synchronizaon or ZSync is being employed.
• Physical locaon of BaseStaon antennas (either on BaseStaons or on Transceivers).
• Physical locaon of the BeltStaons.
• Specic hopping paerns selected.
• Environment (wide open, reecve, through walls…).
Favorable system condions include:
• Locaons with lile or no interference from other 2.4GHz devices will provide the best opportunity for a large
number of collocated systems.
• Proper use of synchronizaon resolves potenal de-sensing issues.
• Antennas of any parcular system should be separated from every other system’s antennas by at least 10 feet (3
meters) for best collocated system performance.
• BeltStaons operang at similar distances from their respecve BaseStaon antennas provide the best opportunity
for sasfactory performance of a large number of collocated systems.
• Network Number conguraon should be set up to ensure each system’s hopping paerns are congured properly.
See the secon on Network Number for more informaon.
• Environment can play a big role in RF system performance. Every locaon is dierent and has its own unique set
of challenges. Generally speaking, locaons with very long paths to very reecve surfaces tend to be the most
dicult for digital wireless communicaon systems due to the prevalence of inter-symbol interference.
Adverse condions will limit the number, eecveness, and range of collocated systems in any given environment.
