[c-nsp] Protecting Wireless Network from Jammers

[Felix Nkansah]

Hi,

Most cities around the world (like Chicago in the USA) have deployed
wireless mesh networks (operating in the Public Safety 4.9 Ghz band) for
connecting their city-wide surveillance cameras.

Since wireless networks are vulnerable to spectrum jammers, I am wondering
how the authorities prevent rogue citizens from jamming these wireless video
surveillance networks, even if temporary?

Is there some kind of technology that can be used to make wireless networks
less susceptible to jammers?

Thanks. Felix
