Just a quick question that should be simple to answer for you wireless gurus out there. I have a basic understanding of wireless technology, but given that I don't have a whole lot of wireless toys to play with over here, the scope of my knowledge is rather limited.

So I've been told that there has been a problem with 802.11g equipment running at 2.4gHz in that phones that run on the same frequency cause interference on the network. My understanding is that new 5gHz technology has recently been released. Do the 5gHz devices eliminate this problem, and thus are they a better investment than older 2.4gHz equipment? If not, how does one approach this problem?
