Are there internal cell systems inside the venue? What is cell strength on phones?
Reflections and directionality have nothing to do with this. High noise floor is the problem.
Try your antenna run outside the building. Success in fixing this has been done by putting antennas far from the high noise floor.
Walk the venue looking at the noise floor. Is the band below -100 dBm? Noise floor above -80 will totally stop the system.
Hi Pete/ Henry/ Jason,
Back in the UK now so more time to try and learn more about the problems experienced and how to preferably avoid or solve in the future.
I have little experience in scanning DECT and was hoping to gain more insight into what you look for yourself when using FSii?
- Noise floor of -100dBm is ideal
- Noise floor of -80dBm is a critical limit to system use.
- Consistent or burst transmission by FSii is considered 'normal'
- Spectrum use of the bands nearby and potential intermod or bleed increasing noise floor.
I believe FSii uses GFSK frequency modulation and I'm trying to research the details of how it works but I'm ultimately trying to build a picture of comparison to when I normally scan for Radio Microphones/ IEM's etc. I unfortunately wasn't trained as an Electronics/ RF Engineer.
Pete, you mentioned Henry and yourself experienced this Audio Stutter problem recently. Could you explain any similarities or differences you had and how you worked towards a solution if you got one?
Kind Regards,
Marc
