    Default Lines, Lines, Lines????

    Anyone able to help with this one...

    It is pick up in an industrial area where we manage a mesh network.

    Its only picked up within a about a 1km square radius and seems to have a rendered channel 1 useless for any devices wanting to use this channel???

    I'm talking about the diagonal lines not the cordless phone on 2414.

    Hello Shane,

    It is hard to say for sure. Would it be possible to attach a recording or send the recording to

    Could you please upload a larger & clearer image with regard ti the Density view/topographic view. Or a recording.

    Just taking a stab at it it looks like it is 10 MHz wide and OFDM or DSSS modulation. Could be a back-haul of some sort, like a Motorola Canopy or Alvarion BreezeAccess VL ? looks a lot like 802.11, but since channel size if different probably a proprietary manufacture spec. Most RFID reader Ive run into will tend to use the whole band so I don't think it is that.. But it is definitely not a machine or that sort of thing making interference... The line suggest otherwise to a very specific modulation type..
