Iam having one doubt 
that will signal jammer will object our Wifi(2.4Ghz&5.8Ghz) signal 
.???
your question is not clear. are you afraid of signal jammers? well there is nothing you can do, if a bad person wants to hurt your business, he can come and steal your antenna. there are always things you can’t control
Some of the best jammers are the first generation of buffalo mimo crap…
Actually i am using router as wireless cpe and the site is near to one political party office.For security reasons they will use signal jammer.so can i establish wireless link or not???
will they observe our rf signals(2.4Ghz or 5 Ghz)
find out what frequencies are being disturbed by the jammer. if you use a wireless card like the R52 - you can use ranges from 2.3-2.5 or 4.9-6GHz. I think there must be a frequency that will not be disturbed by it, just experiment at which one it works best.
can you tell how to do experiment???.can i use laptop for this purpose
no, you will have to install your link and then change frequency until it works great
Before using this equipment check the legal side of such practice in your country … consequences may be very expensive if you use unauthorized jamming of licensed signals.
