System Overview
System Description
A ROAMEO wireless intercom system consists of two types of devices: a wireless beltpack (TR-1800) and an access point
(AP-1800).
The ROAMEO system can be configured for anything from small systems (one access point and a few beltpacks) to a large
system (10 access points and up to 40 beltpacks). The ROAMEO system provides quality, configurable wireless audio across
the coverage area and is easily expandable.
The typical indoor coverage area varies widely depending on the installation area. The typical range of an access point is
between 50–100 meters.
System Considerations
• Number of access points required for coverage area.
• Sufficient access point coverage overlap to allow seamless roaming for beltpacks.
• The number of access points to provide sufficient capacity for all beltpacks planned to be in the area. It is especially
important to consider the number of beltpacks that are booted in the same area (and then moved to other areas). The
initial beltpack staging area should be able to provide access to all devices.
• Area Considerations
• Metal Barriers - Signal reflects off metal which can provide good signal fill for areas; however, the
signal will not pass through metal.
• Cement - Signal usually passes through with little problem. Dependent on the cement thickness
and the presence of any metal rebar.
• Wood and Drywall - No issues.
• Overall Size - May need more access points to cover a large area even if only a few beltpacks are
used.
• Spectrum Bandwidth - Other DECT systems in the area (i.e., wireless phone systems use some of the DECT
spectrum allowing less beltpacks in the area).
• Matrix system supports enough OMNEO channels for the amount of beltpacks.
• Ethernet infrastructure supports access points with sufficient bandwidth for additional traffic and uses managed
switches (OSI Layer 3 capable).
