ROAMEO System Setup Checklist
❐
Each beltpack has only one HOME access point.
❐
Each system can have only one Sync Master access point (set in IPedit).
❐
When subscribing a beltpack to the system, the beltpack must be within 40 feet (12 meters) of an access point in
that system.
❐
Each access point set to the G.722 CODEC can be a host for up to five beltpacks (no channels left for roaming
beltpacks).
❐
Recommend each G.722 access point only be loaded to four beltpacks to allow for roaming beltpacks.
❐
Each access point set to the G.726 CODEC can be host for up to 10 beltpacks (no channels left for roaming
beltpacks).
❐
Recommend each G.726 access point only be loaded to eight beltpacks to allow for roaming beltpacks.
❐
If the CODEC is changed for a system, the beltpacks must be subscribed again.
❐
A system can only have all G.722 or all G.726 access points (no CODEC mixing is allowed).
❐
Always have Ethernet connected to an access point before powering up the access point.
❐
The Ethernet network follows standard Ethernet practices.
❐
Use only CAT5e UTP or better Ethernet cable.
❐
Use only Layer 3 IP routing-capable, managed switches.
❐
100Mbit networks can only have up to seven hops (A link between the Matrix and an Ethernet switch counts as a
hop, each link after daisy chaining through an access point counts as a hop).
❐
1GBit networks can only have up to 20 hops (A link between the Matrix and an Ethernet switch counts as a hop,
each link after daisy chaining through an access point counts as a hop).
❐
Maximum system size is 10 access points and 40 beltpacks.
❐
The overlap RF coverage area between two adjacent access points should have an RSSI reading of 80 or better
from each access point for error free roaming.
❐
In a high density beltpack coverage area with more than six access points (G.722) or more than 10 access points
(G.726) covering the area, all access points must be within each other’s -70dBm RF coverage contour (112 or
better on the beltpack’s RSSI site survey screen).
❐
If a PoE adapter is used, access points cannot be daisy-chained. Only one access point can be powered from the
PoE adapter. For more information, see “Power Over Ethernet” on page 57.
