On the FreeSpeak Edge Wireless System, frequencies can be manually set at each transceiver. When coordinating the frequencies, you have to be careful that transceivers set to the same frequency can not be seen by each other, otherwise, your beltpack will have an issue roaming from one transceiver to the next.

To see if your transceivers are too close together, use the beltpack’s menu to place your beltpack into Site-Survey mode (<Diagnostics> / <Site Survey>). While roaming between the two transceivers with the same frequency, look for a red dot as illustrated in the image.

Open

The RPN (Transceiver, or XCVR) with the green dot is the transceiver that your belt pack is connected to, and the transceiver with the red dot is the one that is on the same channel and can be seen at the same time.

If you see the red dot, then that means you should either change the frequency on one of the transceivers or reduce power to reduce overlap.

Additionally, if only one of the two channels is in conflict, you will still see a red dot. Pay close attention to the two channels to see which one is in conflict and with which transceivers.

Sticky roaming

If Edge antennas are too close to each other in terms of RF channels or physical distance , this can also present a “sticky antenna” or sticky roaming issue

Sticky roaming can be a symptom, where transceivers are too close in proximity, and /or different power output between transceivers.

First test is to put a Edge BP beltpack into site survey mode and check the area were your having issues if you see a red dot like the picture above than the transceivers are in conflict with each other, In this case change the channels so they are not in the same range

We suggest channels should be 6-8 channels apart on each transceiver, along with increasing the distance and decreasing the overlap between transceivers,  FS Edge transceivers should be kept 6-8 meters apart to avoid co channel interference.

Another cause of sticking roaming is transceiver output power.

Example in Europe 5G RF Channels 36-140 have a maximum output of 23 dBm, while channels 149-173 have maximum output of 14 dBm.  If one transceiver is using Rf channels 36-140(@23 dBm) and the other is using 149-173 (@14 dBm) that could be the cause the BPs to connect and stick with the higher power antenna.

In this case we suggest reducing the output power on the transceiver that is sticky and narrowing the overlap gap between transceivers, which should force beltpacks to roam.
