User Guide| FreeSpeak II for Eclipse HX
In some environments you might observe that despite having a high signal strength, the beltpack
consistently reports a high error rate.
This could be due to two things:
l In-band interference from an RF source broadcasting in the DECT area of the spectrum.
This can be verified using a DECT band monitor or by using a Spectrum Analyzer.
l Long Delay Spread Multipath, where the signal is bounced off a number of reflective
surfaces, such as metal ceilings, gantries, walkways or other large structures. This problem
is greatest where the reflective surface is large and exists at a range of distances from the
transceiver. To reduce the problem, consider siting the transceiver where it cannot “see” the
reflective surface or installing a reflector close to the transceiver between it and the
reflective surface.
7.9.2 Testing transceiver handoff
After testing the coverage areas for individual transceivers, test the handoff between the
transceivers. When you walk through a coverage area with the beltpack, the beltpack searches to
find the transceiver with the best signal strength, and switches transmission to that transceiver.
Therefore the beltpack continually hands off transmission among transceivers as you move
through the coverage area. You can determine which transceiver the beltpack is connected to
using the EHX configuration.
