We have an interference problem come up this week that we have been unable to
resolve.Hopefully someone here has some input on how to resolve it.The problem
is walmart installed a rfid scanning system at there loading dock which

Hi,
You may want to try changing polarity and see if that helps. Often going
from vertical to horizontal will make a big difference.

I am looking for some advice on the proper climbing technique for a new

hundreds of towers including free standing, guyed, 40ft to 120ft without

Thanks for the input .that is a possible solution but not one that could be
implemented quickly or easily.It would require a new Hpol omni about $2200
a climb to install it and a trip to about 100 customers home to change their
eum antenna to h pol.This may be how it gets resolved but
If their signal occupies the whole band it is probably FHSS in nature.
So changing to a 5 or 10 Mhz. channel will not be possible. Also, it
may not be possible to turn down the power. So it may not be that simple.
A certified letter from an attorney is probably more in order.
How far is this from your site? Are they exceding 36db ERP?
If they are exceding ERP and you can prove it by taking spectrum
analyser out there have your lawyer send a certified letter to ADT and
Walmart manager with this info and quotes from FCC rules and
regulations.

no, 900 mhz rfid would be 20mhz bands. They MUST be exceeding EIRP, tho,
because I've never seen problems with rfid at close ranges like that, and
not having good reads with normal, or even less than normal power. Problem
is, rfid is 100% tx/rx 100% of the time.
How far away is this from you ?
That's what I thought too... the problem is the tower climb pegs stop at
the 80ft level... there is no way to keep climbing up higher... :(

Ya... that's the problem with unlicensed stuff... we've had to switch
many of our 900mhz towers to horizontal after having 100+ customers on
them... lucky for us, we only have to visit the customers we installed
external antennas (usually less than 10%), because of Trango's dual-pol

The bigger issue is are your customers going to wait WEEKS while you
try and resolve this via attorneys, etc. My customers would be
SCREAMING after the first hour of downtime.
The fastest solution is to switch to h-pol and start changing customers.

Again... are those 100 customers going to wait a few weeks while you

It appears that some idiot who supervised this tower installation wasn't
paying attention. Be careful and use your monkey tales and just go
across the bracing as safely as you can. 100% tie off.

Yea, I agree the connection for those customers needs to be the
priority. But, taking more than one direction of fixing the problem is a
good idea. What if the store is over EIRP and switching to h-pol only
marginally improves the signal? Then its back to square one on getting
the problem fixed.
Not sure how big or your small the town/city is, but maybe you can get
on the phone with the mayor or city manager, someone with political
clout that can put pressure on them to at least contact you and attempt
to try to solve the problem.

I'm a big fan of trying to work things out.
In person if need be. Show up at the store and ask them if they can at
least try turning the power down etc. If they say they can't adjust it,
then they can always put in attenuators between the radio and antennas they
are using.
If they still

The left leg has pegs from the ground to 80ft. The far leg has pegs from

and a 3ft) on the leg with all the pegs... so there is no way to climb

If they are using FHSS Bob, sure they can reduce their channels. The
rules now allow use of any or all channels in FHSS, including avoiding
certain frequencies. Doing so just requires low power.
