Rssi is very important to determine if a link is properly aligned and its 
achieving its link budget.

Altough we don’t use alvarion(yet), we are currently researching backhaul 
options and the way we comission ptp links here is that we run the calcs on 
radio mobile and spreedsheet to determine the link budget in advance to 
implementation.  Snr won’t help much there...

    Software controlled dual polarity might be nice. Not sure why you
    consistently harp on us though since no one else has it either other
    than your longtime preferred vendor.
    I am not as convinced about your complaint about RSSI. Is it just used
    to RSSI like being used to feet in stead of meters. But also, isn't RSSI
    less sophisticated and a less useful number than SNR since it is only an
    indication of receive signal without discounting noise? SNR provides a
    more accurate representation of wanted signal since it discounts for
    unwanted noise.
    Not sure of your complaint about the RJ45. No one else remarks about it
    and we don't have issues with water intrusion. In other words, it works
    well. If the opening was enlarged you increase the potential for water
    Following the color code? Yes, as an old cabling guy, I would agree. But
    I am pleased to note that one is really running out of things to harp
    about when one continually highlights this a major deficiency.
    So now that I have responded here to your public mail, will you please
    admit that even if the VL came to life and saved your kid from a flood
    you complain that it was not fast enough and that it ripped the kid's
    clothes. I wish some day you'd accept that your customer chose VL and
    you should take the opportunity to learn about it instead of still
    trying to make it fail so you can get them to switch to Trango. Even the
    best radios will have room for improvement and every decent brand should
    have something special that differentiates it. You work so hard to find
    fault you miss opportunities to become proficient in more than one
    brand. So accept our invitations to allow engineer visits and accept our
    invitations to be trained. Know what I mean?
